Multiple Myeloma Patient Handbook
EDUCATION · AWARENESS · ACCESS · RESEARCH
Providing information and support for Canadians living with multiple myeloma

Introduction
This resource has been designed for:
1. A person who has been newly diagnosed with myeloma and is wondering what it means and what
the future will bring.
2. Those who have been living with myeloma for some time, but would like to refresh their understanding
of the disease or fill in any missing pieces.
3. A person who is a family member, friend or loved one of someone with myeloma, and who wants
to gain a better understanding of the disease and treatment options.
The goal of this resource is simple: to educate myeloma patients and their loved ones so they can become
a more active partner in their care.
If you have been searching for information on myeloma, you know how complicated this can be. This resource
is an attempt to give you accurate, reliable and clear information on myeloma, its causes and effects, and how
it is diagnosed, staged and treated in Canada.
There is a lot of information in this handbook and the more times you refer to it, the easier it will for you to
understand it. And don't be afraid to ask the members of your healthcare team to explain any term you don't
understand. Over time, you will better understand your disease, your treatment options and what you can do
to optimize your quality of life.

Chapter 1
What is Multiple Myeloma?
In this chapter, we'll define what is meant by "multiple myeloma" and its
underlying disease process. Some of this information may appear intimidating
or complex at first. Don't worry over time you will understand more and
more. Refer to this resource frequently and don't be afraid to ask your
healthcare team for explanations.
As early as possible, start collecting and organizing key information about
your condition and your care.This should include contact information for
the members of your healthcare team, copies of your lab results, your medication
regimens and side effects.You'll find information on these and other issues
later in this resource (Chapter 9 HowTo BeYour OwnAdvocate).In Chapter 7,
we'll also talk about how to optimize communications with the main partners
in your treatment your healthcare team.
Of Bone Marrow and Plasma Cells
You have probably heard the terms "multiple myeloma" and "myeloma".
These terms refer to the same thing: a cancer of the plasma cells. Plasma
cells are found in the bone marrow, the hollow area within the bones.
Because plasma cells are found in the blood, myeloma is referred to as
a hematologic or blood cancer. The word "multiple" is often used because
the malignant cells usually affect multiple areas of the bone marrow.
In this resource, we'll use the term "myeloma" to keep things simple.
| What is Multiple Myeloma?

Myeloma vs. Melanoma
It's not uncommon for people to confuse "myeloma" with "melanoma". Myeloma is a cancer of the plasma cells
in the bone marrow. Melanoma refers to a form of cancer that usually occurs in the skin, but can also occur in
the eye and mucous membranes.
Your bone marrow is a sort of "blood factory" where three kinds of blood cells are made:
1. Red blood cells that carry oxygen.
2. Cells called platelets (or thrombocytes) that help the blood to clot whenever you cut yourself.
3. A variety of white blood cells including lymphocytes that plays important roles in the functioning of
your immune system. There are two types of lymphocytes: T cells and B cells. Another variety of white
blood cell you may hear of is the neutrophil. This plays an important role in protection from infection.
If you have a low neutrophil level you are more susceptible to infection.
With regard to lymphocytes:
The abbreviation "T", in T cell (or T lymphocyte), stands for thymus since it is the principal organ
for their development.
B cells (or B lymphocytes) are found in the bone marrow. As they mature, B cells turn into plasma cells.
When plasma cells are exposed to foreign substances (antigens), they produce different antibodies. These antibodies
are called immunoglobulins (the short form is Ig).
Immunoglobulins are proteins made up of two types of chains:
heavy chains (G, A, M, D or E) and
IgG
Light chain
light chains ( kappa, , or lambda, ).
Heavy chain
Normally, the most common immunoglobulin in the blood
is IgG, followed by IgA and IgM. IgD and IgE are usually
present in the blood in only very small amounts.
What happens when you have myeloma? In myeloma,
the B lymphocyte (the cell that matures into a plasma
cell) is damaged. It begins to reproduce plasma cells
uncontrollably. We commonly refer to this "good cell gone
bad" as being malignant.
What is Multiple Myeloma? |

When plasma cells reproduce uncontrollably, two things happen.
Too many plasma cells are produced. In healthy people, plasma cells
make up 2-3 % of the cells in the bone marrow. In someone who has
myeloma, plasma cells make up at least 10 % of the cells or even
more. The abnormally high number of plasma cells can "crowd" out
other types of cells you need to be healthy, such as red blood cells
or platelets.
Too much of the same immunoglobulin is produced, such as too much IgG or IgA. This is referred
to as the monoclonal protein (M-protein), monoclonal spike (M-spike), monoclonal peak (M-peak),
or paraprotein. For more information about the M-protein and the different types of myeloma, please
refer to Chapter 2.
When myeloma cells enter the bone marrow, they attach to other, structural cells of the bone marrow known
as stromal cells. Once attached to stromal cells, interactions occur that stimulate the myeloma cells to continue
reproducing.
Chemical messengers called cytokines are produced that stimulate the growth of myeloma cells and
prevent the cells from dying naturally. Interleukin 6 (IL-6) is one of these chemical messengers.
The myeloma cells secrete chemicals called growth factors that promote the creation of new blood
vessels that usually accompanies the growth of malignant cells (a process called angiogenesis). One of
the most important of these growth factors is vascular endothelial growth factor (VEGF).
The immune system begins to fail. Ordinarily your immune system would try to clear out or stop
the growth of abnormal cells. But as the immune system weakens, it is unable to battle the abnormal cells.
As the myeloma cells invade the bone, they cause multiple areas of damage
that weaken the bone. These areas are known as osteolytic lesions, or lytic
lesions for short.
Sometimes, the myeloma cells collect in a single bone and form a tumour
called a plasmacytoma. Occasionally, a plasmacytoma can even affect areas
of soft tissue outside of bone.
| What is Multiple Myeloma?

History of Myeloma Research
The first medical descriptions of myeloma date back to the 1840s. By
the early 1900s, the role of plasma cells in the development of myeloma
had been described and X-rays were being used to find areas of bone
involvement (lytic lesions). It was not until 1962 that the first modern
treatment of myeloma, the chemotherapy drug melphalan, was available.
The use of this drug together with prednisone was first described by
Dr. Daniel Bergsagel from the University of Toronto. For many years,
melphalan and the steroid prednisone, the "MP" regimen, was the only
available treatment for myeloma.
In the 1970s, various combinations of chemotherapy agents were developed,
such as VAD (vincristine, Adriamycin® and dexamethasone). Bone marrow
transplants for myeloma patients began in the 1980s. It was not until 1996,
however, that a randomized controlled trial was able to show a clear
benefit for high dose therapy followed by a bone marrow transplant.
Research has been able to increase both our understanding of the genetics
of myeloma and the underlying disease process. This has resulted in
the development of new approaches to treating myeloma and new therapies.
Although there is still no absolute "cure" for myeloma, a growing number
of patients with active myeloma are living ten or more years after diagnosis.
We are also getting better at treating the complications of myeloma, giving
people with the disease the best possible quality of life for the longest
time possible.
What is Multiple Myeloma? |

Incidence and Prevalence in Canada
There are approximately 6,000 Canadians living with myeloma. It is estimated
that in 2006, 1,900 new cases of myeloma were diagnosed in Canada, and
there were 1,300 myeloma deaths. Men outnumbered women among both
newly diagnosed cases (there were 1,050 men and 850 women) and deaths
(700 men and 620 women). Myeloma makes up 1.3 % of all new cancer
cases in Canada and 1.9 % of all cancer deaths.
Myeloma is fairly rare before age 40, and most people are in their 60s when
they are diagnosed.
We know that the incidence of myeloma varies from country to country,
from a low of less than one per 100,000 people in China to a high of about
four per 100,000 in most Western industrialized countries. In the United
States, myeloma is more common in African Americans than Caucasians.
Although we know that genetic changes are present in myeloma cells, there
is no evidence that myeloma is a hereditary disease. Factors that may be
associated with an increased risk of myeloma include exposure to toxic
chemicals, radiation and possibly some viruses. There is still much to learn
about what causes myeloma.

Chapter 2
Types of Myeloma
Myeloma is not really one disease. In this chapter we will look at the different types of myeloma. The chart
at the end of the chapter also summarizes the different criteria for each type.
Monoclonal Gammopathy of
Undetermined Significance (MGUS)
This is a benign condition in wich the M protein is present but there is
no underlying disease. MGUS can, however, be a precursor of myeloma.
In someone with MGUS:
There may be more plasma cells than normal in the bone marrow,
but it is still less than 10 % of all blood cells (part of the definition
of myeloma includes 10 % or more plasma cells).
Monoclonal (M) protein level in the blood is usually less than 30g/L.
There is no anemia (low blood hemoglobin), renal failure (kidney
disease), hypercalcemia (high levels of calcium in the blood) or
bone damage (lytic lesions).
Why is MGUS important? It is important because about 1 % per year of
people with MGUS will go on to develop active myeloma. Currently, there
is no clear way to predict who will progress to active myeloma. MGUS is
usually monitored but not treated.
Types of Myeloma |

Asymptomatic Myeloma
In some patients, there is a transitional state, called asymptomatic myeloma,
(also known as smoldering or indolent myeloma), that lies between MGUS
and active myeloma. In asymptomatic myeloma there are few signs of active
disease or the myeloma remains unchanged or stable.
In asymptomatic myeloma, plasma cells may make up 10 % or more of
the bone marrow and/or there is an M protein (M-spike or M-peak) greater
than 30 g/L. However, there is still no anemia, renal failure, hypercalcemia
or bone lesions. Because the disease is not yet active, asymptomatic
myeloma is usually observed but not treated. Supportive care, such as
drugs to strengthen the bone, may be given.
Symptomatic or Active Myeloma
Active myeloma is characterized by the presence of M proteins in the blood
or urine and an increased number of plasma cells in the bone marrow. Another
possible sign of active myeloma is the growth of a plasmacytoma or tumour
in the bone or soft tissue.
People with symptomatic or active myeloma can develop complications
such as anemia, kidney failure, or excessive levels of calcium (hypercalcemia)
in the blood. Soft spots (lytic lesions) can appear on X-rays of the bone.
These lesions weaken the bone, causing pain and increasing the risk of
fractures. People with symptomatic or active myeloma require treatment.
Myeloma is often referred to by the type of immunoglobulin (monoclonal
protein) or light chain (kappa or lambda) that is over-produced by
the cancerous plasma cells. The excessive level of one type of immunoglobulin
is referred to as the M-protein, M-spike, M-peak or paraprotein.
0| Types of Myeloma

Mproteins
In the previous chapter, we saw that immunoglobulins can be
defined by the type of heavy chain they contain (G, A, M, D or E).
About 60 - 65 % of all cases of myeloma involve the overproduction
of IgG. In about 20 % of cases, it is the IgA protein that is involved.
Myeloma can also involve IgD or IgE but these forms occur
less frequently.
Uncontrolled production of IgM is a rare form of plasma cell cancer
known as Waldenstrom's macroglobulinemia. Excessive amounts
of IgM cause the blood to thicken (hyperviscosity). Symptoms can
include enlarged lymph nodes, spleen or liver, fatigue due to anemia,
headaches, weight loss, a tendency to bleed easily (due to too few
platelets in the blood), visual problems, confusion or dizziness.
In extreme cases, the increased concentration of IgM in the blood
can lead to heart failure.
LightChainMyeloma
Although a high level of M protein in the blood is a hallmark of myeloma, about 15 - 20% of patients produce
only the light chain portion of the immunoglobulin. These are referred to as free light chains because
they lack the heavy chain portion of the M protein. Light chain proteins are also referred to as Bence-Jones
proteins, after the physician and chemist who discovered them in the urine of myeloma patients.
When free light chain proteins are in the urine, they can accumulate in the kidney and damage it. A 24-hour
urine collection is usually required to measure and monitor the light chain proteins. Some laboratories,
however, now have tests that can detect and measure free light chains in the blood.
When very small amounts of M protein are produced by the malignant plasma cells it is called oligosecretory
myeloma. Sensitive measurement of the M protein called Freelite® testing may be available in some centres
and be useful in monitoring this type of myeloma.
Approximately 30% of patients produce light chains in the urine as well as heavy and light chains in the blood.
NonsecretoryMyeloma
About 1 % of myeloma patients do not produce enough M proteins or light chains in the blood or urine to
be detected. Again, Freelite® testing may help to measure levels of free light chains in these people.
GeneticSub-Types
It is now known that there are multiple different genetic (DNA) abnormalities associated with myeloma. Having
one of these genetic abnormalities affects how your disease will respond to different treatments. In the future,
genetic profiling will play an increasingly important role in the customization of myeloma treatments.
Types of Myeloma |

Amyloidosis
About 10 - 15% of people with myeloma will have or develop amyloidosis. In amyloidosis, the myeloma
light chains (Bence-Jones proteins) form protein deposits called amyloid. The amyloid can collect in one
or more organs causing the organ to malfunction. The heart, kidneys, nervous system and gastrointestinal
tract are most often affected.

Chapter 3
Diagnosing Myeloma
During the early stages of myeloma, there may be no symptoms. Most people first go to their doctor because
of vague symptoms that can be difficult to diagnose, such as fatigue, recurrent infections or back pain.
Common symptoms of myeloma can include any of the following:
Symptom
WhyItOccurs
Pain in the lower back, ribs Osteolytic lesions weaken the bone, resulting in tiny fractures or even
or sternum
the collapse of a vertebra in the spine. About 70 % of myeloma patients
seek medical attention because of pain.
Fatigue
The increased number of myeloma cells can decrease the production of red
blood cells in the bone marrow, leading to anemia.
Recurrent infections
Due to crowding in the bone marrow, the production of a variety of infection-
fighting white blood cells is reduced. The immune system is unable to fight
off infections and illnesses.
Tiredness accompanied by The breakdown of bone releases excess amounts of calcium into the blood
other symptoms such as thirst, (hypercalcemia). Hypercalcemia can result in a number of symptoms, such
frequent urination, nausea as loss of appetite, fatigue, muscle weakness, restlessness, difficulty in thinking,
or muscle weakness
confusion, constipation, increased thirst, increased urine production, and
nausea and vomiting.
Kidney problems
Excessive protein in the blood (which is filtered through the kidneys),
excessive light chains in the urine or high levels of calcium in the blood
can cause kidney damage.
Diagnosing Myeloma |

How Myeloma is Diagnosed
Diagnostic lab tests help to:
Establish whether there are monoclonal proteins (M proteins) in
the blood or urine.
Confirm the presence of abnormal numbers of malignant plasma
cells in the bone marrow.
Determine whether or not there is organ damage as a result of
the myeloma (for example, bone damage or kidney dysfunction).
In short, diagnostic testing will tell you whether you have myeloma and
what stage your disease is in.
Prognostic lab tests will:
Determine the tumour burden (the severity of your disease).
Suggest how aggressive the cancer is.
Some prognostic tests can even characterize the genetic abnormalities of the cancerous plasma cell. Prognostic
tests help you and your doctor determine the best course of treatment.
Whether diagnostic or prognostic, lab tests for myeloma involve testing the blood, urine and bone. How
frequently you will undergo testing will depend upon:
How rapidly the myeloma is advancing.
What symptoms you are experiencing.
What treatment you are undergoing.
When undergoing treatment, some people may undergo testing monthly or even weekly; at other periods
you may not require testing for much longer periods of time. There is no one "schedule" for testing
everyone's condition must be assessed individually.

BloodTests
A Complete Blood Count (CBC) measures the number of white and

When studying the results of a CBC, your doctor will look for:
·
a decreased level of hemoglobin (an indication of anemia)
·
a decreased platelet count that can cause bleeding problems
(referred to as thrombocytopenia)
·
a decreased level of white blood cells which causes the immune
system to weaken (referred to as granulocytopenia)
Although values can vary, normal CBC results are summarized in
the following chart. Values that are significantly outside of the normal
range will raise questions and may lead to other tests.

Blood chemistry tests wil also be conducted. These tests look for indications of:
·
Increased levels of total protein in the blood
·
Poor kidney function (renal dysfunction). Indicators include :
-
abnormal blood urea
-
increased creatinine
·
Decreased albumin
·
An elevated level of lactate dehydrogenase (LD or LDH)
·
More bone breakdown than normal. Indicators are:
-
hypercalcemia, an elevated calcium level in the blood that
occurs when calcium is released from the bone
-
in some cases, there may be elevated levels of alkaline phosphatase
(ALP); in other cases, lytic lesions can occur without any increase
in ALP levels
Other tests that may be performed include measuring the level of:
·
Beta-2 microglobulin ( 2-M ), an indicator that tumours may be present in the blood.
·
C-reactive protein (CRP), an indicator for interleukin-6 (IL-6), a growth factor for myeloma cells.
Once the diagnosis of myeloma is made, even more specialized blood tests may be ordered to confirm
the diagnosis and determine what type of myeloma you have.
·
Serum protein electrophoresis (SPE or SPEP) gives a picture of the level of various proteins in
the blood. SPE shows if there is a monoclonal peak or abnormal level of a particular immunoglobulin,
as well as kappa and lambda free light chains. Electrophoresis can also be conducted on urine
(UPE or UPEP).
·
Immunofixation is the test used to type the monoclonal paraprotein or M-Spike seen by SPE.
Immunofixation can also be conducted on urine.
·
A quantitative immunoglobulin (QIG) test measures the levels of different types of
immunoglobulins or antibodies in the blood (IgG, IgA and IgM).
·
New tests can measure the level of free light chains in the blood (serum free light chain assay,
such as Freelite®).
| Diagnosing Myeloma

UrineTests
When myeloma is suspected, urine tests may be ordered. Urine tests
can be used to:
·
Measure the amount of protein in the urine
·
Look for free light chains
·
Test for creatinine, a waste product excreted by the kidneys
·
Look for bilirubin, a breakdown product of hemoglobin
A 24-hour urine test may be conducted to measure the amount of
protein in the urine over a day. Urine protein electrophoresis (UPE
or UPEP) may be done to look for free light chains in the urine
and to assess kidney function. If they are present, your doctor may
follow up with urine immunofixation or blood tests.
These tests can help to determine what stage of the disease you
are in or how the disease is responding to treatment.
TestsConductedontheBone
X-rays can be used to check for changes in the bone structure and to determine if there are osteolytic
or lytic lesions in the bone (weak spots). A bone (skeletal) survey consists of a series of X-rays of
the skull, spine, arms, ribs, pelvis and legs. Less frequently, other imaging techniques may also be
used, such as Magnetic Resonance Imaging (MRI), Computerized Axial Tomography (CAT or CT-scan)
or Positron Emission Tomography (PET scan).
Samples of the bone marrow may also be taken to check the number of plasma cells. There are two
bone marrow sampling techniques. In both cases, samples are usually taken from either the hip or
breast bone (aspiration only).
Bonemarrowaspiration-- a needle with a syringe attached is used to draw a sample of liquid
bone marrow. As well as examining the sample under a microscope, the cytogenetics of the plasma
cells can be studied.
Bonemarrowbiopsy--a biopsy needle is inserted into the bone and rotated to force a tiny
sample of solid bone tissue into the needle. A biopsy is usually performed when you are first
diagnosed and may not need to be repeated.
Diagnosing Myeloma |

Cytogenetics the study of the structure of chromosomes (the ribbons of
DNA that make up our genes).The two techniques most commonly used in
the cytogenetics of myeloma are karyotyping and Fluorescence In Situ
Hybridization (FISH).
Karyotyping a means of looking at the chromosomes of an individual
cell arranged in pairs and sorted by size.This test can detect large genetic
changes, such as the existence of an extra chromosome.
FISH a powerful molecular technique that uses a fluorescent-labelled
probe to determine the presence or absence of a particular segment of DNA.
It can detect even small changes, such as the translocation or rearrangement
of chromosome segments.

Chapter 4
Staging Myeloma
In the last chapter, we discussed how some tests are considered "prognostic".
Prognostic tests are not conducted in order to tell you whether or not
you have active myeloma, but to figure out more about the disease and
how advanced it is (known as its "stage"). Prognostic testing will help to
determine what sort of care is appropriate for you.
There are several systems that are used to "stage" active myeloma. The two
main systems are the International Staging System (ISS) and the Durie-Salmon
Staging System.
The ISS system is based upon two blood test results:
Beta-2microglobulin(2M)-- 2M is a protein that is normally
found on the surface of cells. A higher-than-normal level of this
protein indicates inflammation somewhere in the body. It may also
indicate some types of white blood cell (lymphocyte) disorders.
A normal level of 2M in the blood is usually less than 2.5 g/mL,
dependingonthelaboratory.
Albumin -- The most common form of protein in the blood plasma
is albumin. The normal range for albumin is between 35 to 50 g/L
(in American units, 3.5 to 5.0 g/dL). Lower levels may be an indicator
of kidney dysfunction.
Staging Myeloma |

The Durie-Salmon Staging System requires a number of other blood tests.
They include:
Hemoglobin(Hb) is the protein in the red blood cell that carries and
releases oxygen. Normal hemoglobin levels are 120 to 160 g/L for adult
women and 130 to 180 g/L for men (equivalent American values are 12
to 16 g/dL for women and 13 to 18 g/dL for males). Abnormally low values
may indicate anemia.
Serumcalcium-- Although calcium is an important electrolyte in the body,
too much calcium in the blood can be an indicator of bone disease. Normal
value ranges may vary slightly among different laboratories but are usually
between 2.10 to 2.65 mmol/L (in American units, from 8.5 to 10.2 mg/dL).
Serummonoclonalproteins-- This refers to the level of individual M-
proteins, such as IgG, IgA, etc., or free light chains.
Serumcreatinine-- Creatinine is a byproduct produced when creatinine
phosphate is broken down, an important part of muscle. If kidney function
is abnormal, creatinine levels may be elevated. Because they typically
have more muscle mass, men usually have higher creatinine levels than
women. A normal value of creatinine is usually 50 to 100 mol/L for
women and 70 to 120 mol/L for men (roughly equivalent to the American
values of 0.8 to 1.4 mg/dL).

Your Treatment Options
How your myeloma is treated will depend upon a number of factors, including:
The results of your physical exam and diagnostic testing (blood, urine and bone tests).
The stage of your disease.
What sort of prognostic indicators you may have (e.g., whether a chromosome mutation is identified,
and if so, which type).
Your age and general state of health.
The symptoms you are experiencing, such as bone pain or fractures.
What type of complications of the disease you may be experiencing (e.g., kidney disease, anemia
or infections).
What sort of treatments you have had before and how your myeloma responded to them.
What new treatments are becoming available, such as those accessed by participating in clinical trials.
Each patient is assessed individually. What works for one patient may not work for someone else. Whatever
treatment you are given, the goals of therapy are similar :
Stop the production of abnormal plasma (myeloma) cells.
Strengthen the bone and prevent fractures.
Increase the hemoglobin count and reduce fatigue.
Reduce the risk of infections.
Promote your well-being and quality of life.

Response to Treatment
When reading about myeloma particularly myeloma research you may hear terms such as"Complete Response"
(CR) or "Partial Response" (PR). Different studies may use different definitions, so check the study for what it is
using. The International MyelomaWorking Group response categories are:
sCR(StringentCompleteResponse):Complete Response (see below) plus normal free light chain ratio
and an absence of clonal cells in the bone marrow by immunohistochemistry or immunofluorescence.
CR(CompleteResponse): Negative immunofixation in the serum and urine, disappearance of any soft

tissue plasmacytomas and 5 % or less of plasma cells in the bone marrow.
VGPR(VeryGoodPartialResponse):Serum and urine M-protein detectable by immunofixation but not
on electrophoresis or 90 % or greater reduction in serum M-protein plus urine M-protein less than 100 mg
per 24 hours.
PR(PartialResponse):50 % or greater reduction in the serum M-protein and a reduction in the 24-hour
urinary M-protein of 90 % or more, or to less than 200 mg per 24 hours. If the serum and urine M-protein
are unmeasurable, a 50 % or greater decrease in the difference between involved and uninvolved free light
chain levels is required in place of the M-protein criteria. If serum and urine M-protein are unmeasurable
and serum free light assay is also unmeasurable, a 50 % or greater reduction in plasma cells is required in
place of M-protein, provided baseline bone marrow plasma cell percentage was 30 % or greater. In addition
to these criteria, if present at baseline, a 50 % or greater reduction in the size of soft tissue plasmacytomas
is also required.
SD(StableDisease):Not meeting the criteria for CR,VGPR, PR or progressive disease. SD is not recommended
for use as an indicator of response, as the stability of disease is best described by estimating the time to
progression.
PD(ProgressiveDisease):Requires one or more of the following:
· Increase of 25 % or more from baseline in:
- serum M component and/or urine M component and/or bone marrow plasma cell percentage
(the absolute percentage must be equal to or greater than 10 %)
- development of new bone lesions or plasmacytomas
- development of hypercalcemia attributable to the plasma cell disorder
Since relapses are common in myeloma, you and your healthcare team have to think about not only your
immediate needs but also what you might want to do in the future. Talk with your doctor and your
healthcare team about how you can keep your options for future treatments as open as possible.
| Your Treatment Options

The Three Rs: Remission, Relapse and Refractory
Remission: Complete or partial disappearance of the signs and symptoms of myeloma.
Relapse: The reappearance of signs and symptoms of myeloma after a period of improvement.
Refractory:Myeloma that is unresponsive to a treatment.
At this point, the standard treatments for myeloma are:
Observation
Radiotherapy
Chemotherapy, which can be intravenous (IV) or oral
Steroids
Stem cell transplantation
Thalidomide
Bortezomib ( Velcade® )
Clinical trials
Treatments or drugs are commonly used in different combinations, such as thalidomide and high dose steroids
or melphalan and prednisone. A number of new and emerging treatment therapies are becoming available.
Observation
Sometimes, the best treatment is no treatment at all. If your myeloma is
stable (that is to say, is not progressing or getting worse), the best option
may be to simply monitor your condition. Currently, there is no evidence
that treatment is beneficial for people who have MGUS or asymptomatic
myeloma (smoldering or indolent myeloma), or who have been treated
and are in remission. Research on the role of ongoing or maintenance
therapy is being conducted and approaches may change in the future.
Your Treatment Options |

"First" and "Second Line" Therapies
You may have heard these terms, but what do they mean? A first line treatment is a form of therapy that is
used on people who have not had any previous treatment for their myeloma. If the myeloma does not respond
(the disease is said to be refractory) or if it progresses after the first line therapy has been completed
(i.e., there is a relapse), the subsequent therapy is referred to as second line treatment.
Radiotherapy
High energy radiation may be used to damage the myeloma cells and
prevent them from growing. Radiation therapy is typically used on specific
parts of the body to treat bone pain and plasmacytomas, usually in
combination with some form of chemotherapy.
Total body irradiation was used in the preparation for autologous stem
cell transplantation in the past. Clinical trials have shown that it does
not improve outcome for transplant but does add to side effects. It is
usually not used in conjunction with autologous transplantation anymore.
Chemotherapy
The goal of chemotherapy is to reduce the number of plasma cells in
the bone marrow and the proteins they produce. Chemotherapy cannot
"cure" myeloma but it may put the disease into remission (that is to say,
stop it from progressing or getting worse). It must be tailored individually
to each patient.
There are many forms and combinations of chemotherapy regimens.
Some of the most common in Canada are:
Melphalan, either alone or in combination with steroids such as
prednisone (MP) or dexamethasone.
Cyclophosphamide or cyclophosphamide and prednisone (CP).
VAD ( vincristine, Adriamycin® and dexamethasone ).
CVAD or Hyper-CVAD (cyclophosphamide, VAD).
VMCP/VBAP (vincristine, melphalan, cyclophosphamide, prednisone; alternating with vincristine,
carmustine, doxorubicin and prednisone).
| Your Treatment Options

People with myeloma may receive their chemotherapy intravenously, in cycles of alternating treatment and rest
periods. The rest periods allow patients to recover from chemotherapy-related side effects. They also increase
the chances that tumour cells that are dividing will be exposed to treatment. The length and type of chemotherapy
will depend in part upon whether there are plans to perform a stem cell transplant in the future.
Central Lines
When you are receiving chemotherapy, you may be given a central line or catheter. You may hear it
referred to as a Port-a-Cath®, PICC line or Hickman®. A central line is a long, hollow tube made from silicone
rubber which is inserted or tunnelled under the skin of your chest into a vein.The line can be left in for weeks
or months and makes it possible for you to have your treatment without having to have needles inserted at
each visit. When it is time for your chemotherapy, the nurse or doctor connects the line to a syringe or
intravenous drip.When you no longer need chemotherapy, the line may be removed.
Steroids
Steroids (corticosteroids) are chemicals naturally produced by the adrenal
gland to help prevent inflammation. The synthetic or man-made steroids
most commonly used to treat myeloma are prednisone and dexamethasone.
Steroids can be used alone or in combination with other drugs, such as
chemotherapy drugs.
Your Treatment Options |

Stem Cell Transplantation
Stem cells are cells that can be used to "repopulate" the bone marrow.
They are normally found in the bone marrow and in the blood. There are
several types of stem cell transplantation approaches that may be used to
treat myeloma.
Autologousstemcelltransplantation(ASCT) is the most common. It is referred to as an "autograft"
because it uses your own stem cells. Stem cells can be obtained from blood in the veins (a peripheral
blood stem cell or PBSCT) or your bone marrow. A transplant consists of the following steps:
1. If the stem cells are being harvested from the peripheral blood, drugs are used to "mobilize"
them. By using a medication called a Granulocyte-Colony Stimulating Factor (G-CSF) (e.g. Neupogen®)
with or without chemotherapy, the bone marrow is stimulated to increase the number of stem
cells in the blood. A process called pheresis is then used to collect the stem cells from the blood.
Prior to collection, be sure to talk with your physician about the amount of stem cells that will
be collected. By ensuring that enough stem cells are harvested and frozen to support two or more
transplants, you can increase your treatment options for the future.
2. The stem cells that are collected are frozen and stored until it is time for your transplant. .
3. You then undergo a "conditioning regimen" of high dose chemotherapy with a drug such as melphalan.
This regimen will destroy the cancer cells in the bone marrow. In the process, it will also destroy
the blood-producing cells in your bone marrow.
4. Within a few days of completing the high-dose chemotherapy, the stored stem cells are thawed
and infused back into you. In time, the transplanted stem cells begin to produce new blood cells.
You may or may not stay in the hospital following your transplant.
All treatments have both their risks and benefits. However, studies have shown that on average,
people who undergo ASCT live longer than those who receive chemotherapy alone.
Allogeneic transplant involves collecting stem cells from someone else, usually a brother or sister.
The donor's cells must match the recipient's tissue type note that this is different from blood type
and requires special blood testing. The transplanted donor stem cells may also help attack any myeloma
cells remaining in the patient's bone marrow. This is referred to as the graft-versus-myeloma effect.
Few patients are good candidates for allogeneic transplant. It is difficult to find good donor matches
and the procedure has a greater risk of complications, including infections, graft-versus-host disease
(GVHD, a potentially life-threatening condition in which the donor's bone marrow attacks and destroys
the patient's own tissue) and death. For these reasons, allogeneic transplant is not a standard therapy
for myeloma.
0| Your Treatment Options

There are two types of allogeneic transplant:
·
Ablative or "full" high-dose therapy is used to condition the bone marrow before transplant,
which destroys the patient's own bone marrow cells.
·
"Mini" or non-myeloablative a moderately high-dose chemotherapy conditioning regimen
is used that does not destroy the patient's bone marrow cells but rather causes enough
immunosupression to allow the donor cells to grow in the patient's bone marrow.
A syngeneic cell transplant refers to a transplant using stem cells taken from an identical twin.
The prognosis for syngeneic transplants is better than that of allogeneic transplants; however, this is
an option for only a small number of patients.
Amatchedunrelateddonor(MUD)transplant refers to a transplant using stem cells taken from
a donor who is not a relative but has the same tissue type.
Tandem(double)autologoustransplants are performed in some centres. For a tandem transplant,
the plan is to conduct a second transplant within six months of the first one. This approach may be
beneficial for people who do not have a full response to the first transplant or who have "high risk"
disease, as indicated by age or cytogenetics.
An experimental approach is ASCT followed by a mini-allogeneic transplant. In this version,
a patient first undergoes high-dose chemotherapy to reduce the overall number of myeloma cells,
followed by an autologous transplant. Next there is a second course of moderately high-dose therapy
with an allogeneic transplant of donor stem cells. The second course of therapy in combination
with the help of the allogeneic transplant should reduce the number of myeloma cells.
Maintenance Therapy
The question of whether or not you should continue treatment after a transplant
has not yet been fully answered. Your treatment options will depend upon
your condition, preferences and other factors. Studies are underway which
will give us more information about post-transplant maintenance therapy;
you may be able to participate in such a study and should discuss this with
your physician.
Your Treatment Options |

Is there an age cut-off for stem cell transplant?
Many myeloma centres have a general rule that ASCT is not routinely offered to people above a certain age,
such as 70 or 75 years. These are not hard-and-fast rules. The important thing is not your chronological age
but rather your biological age how generally healthy you are. An otherwise healthy 72-year-old may be
a good candidate for ASCT, whereas a 66-year-old with multiple health problems may be a poor candidate.
Thalidomide
Thalidomide is an immunomodulatory agent. Instead of destroying myeloma cells (like chemotherapy drugs),
thalidomide interferes with the underlying processes that promote the growth and reproduction of myeloma
cells. Thalidomide:
·
inhibits factors that promote the growth of blood vessels (Vascular Endothelial Growth Factor or VEGF
and basic Fibroblast Growth Factor or bFGF) that help to feed tumours
·
modulates the level of several chemicals (called cytokines) that the cancer cells use to communicate
with one another and orchestrate growth and reproduction (e.g., Tumour Necrosis Factor alpha or
TNF-, interleukin 6 ou IL-6, interleukin 2 or IL-2, and interferon-gamma or IFN- )
·
alters the expression of chemicals involved in acute rejection, such as cytokine secretion and cell growth
Thalidomide is used to treat cases in which the myeloma has not responded to treatment (refractory myeloma)
or has returned after treatment (relapsed myeloma). In some countries, it is also used as first-line or initial
treatment. It can be used as a single agent or in combination with other drugs such as dexamethasone,
prednisone or melphalan.
Bortezomib (Velcade®)
Bortezomib ( Velcade® ) has recently been approved for use in Canada for
the treatment of relapsed or refractory myeloma. Bortezomib is a proteasome
inhibitor, one type of the new generation of "biological treatments". It works
by acting on the myeloma cells and the cells with which they interact to
inhibit plasma cell growth and reproduction and to promote cell death.
Bortezomib is given intravenously, usually four times every three weeks.
It can be used alone or with other medications, such as dexamethasone
and doxorubicin.
| Your Treatment Options

New and emerging therapies
A number of new therapies are in development. Lenalidomide (Revlimid®)
is an immunomodulatory drug in the same class as thalidomide. It has been
tested as a sole therapy and in combination with other drugs, such as
dexamethasone. At the time this handbook was printed, clinical trials were
underway in Canada testing lenalidomide in the treatment of refractory and
relapsed myeloma.
Other new approaches are currently being tested. They include:
·
other proteasome inhibitors
·
gene therapy vaccines
·
targeted radioactive agents
·
drugs that reduce the formation of new blood vessels (anti-angiogenesis
agents), block growth factors and/or promote cell death (apoptosis)
Some of these new therapies target not only the myeloma cell, but also
the bone marrow microenvironment (the "neighbourhood") in which
the myeloma lives. One of the most exciting aspects of current research is
the insights that are being made into the genetics of the disease. In the future,
knowing more about the genetics of myeloma will make it possible to more
closely individualize and tailor treatment.
For more information about new and emerging therapies, please refer
to the Myeloma Matrix on the International Myeloma Foundation
(IMF) website (www.myeloma.org). Other sources of information are
the Myeloma Canada website (www.myelomacanada.ca), the Canadian
Cancer Society (www.cancer.ca)and the US National Institute of Health
(www.clinicaltrials.gov).

Chapter 6
Managing Complications and Side Ef ects
The build up of myeloma proteins in the bone marrow can cause a number
of medical problems. It is important that such problems be identified,
monitored and treated.
Complications of the bone
Healthy bones are continually breaking down (referred to as resorption)
so new bone can be laid down. There are two types of cells that are
important for bone:
Osteoclasts -- cells that break bone down. If you are replacing
the roof on your house, one of the first things you should do is tear
off the old roof. Osteoclasts breaks down old bone so there is room
for new bone.
Osteoblasts -- cells that lay down new bone. These are the cells
that follow behind the osteoclasts and strengthen the bone by laying
down fresh, new bone.
Myeloma cells stimulate the osteoclasts the cells that break bone down
while inhibiting the osteoblasts, the cells that make new bone. If there
is more bone breakdown than creation, there can be:
-
areas of damage or "holes" in the bone, known as osteolytic or
lytic lesions
-
progressive bone thinning, called osteoporosis
Managing Complications and Side Effects |

When bone thins or there are lytic lesions:
·
You are at increased risk of fractures. Sometimes, even everyday
activities can cause bones to break. Myeloma patients with bone
disease can experience fractures in the ribs or compression fractures
of the vertebrae in the spine.
·
You may experience bone pain. The majority of myeloma patients
experience bone pain at some point. Words commonly used to
describe bone pain in myeloma include "constant", "aching", "deep"
and "sharp". The pain is often localized and worse when you move
or shift positions. Compression fractures of the vertebrae can occur,
which in turn can cause nerve damage and pain.
What is done for bone disease in myeloma?
·
Skeletal X-rays and bone density tests (a form of special X-ray ) are used to monitor bone loss and
to check for specific areas of damage.
·
People with myeloma are routinely prescribed bisphosphonate drugs that strengthen the bone, such
as pamidronate (Aredia®) or zoledronic acid (Zometa®).
·
Radiation therapy can be used to treat specific bone lesions and help relieve pain. Extensive radiation
of the spine or the long bones should be avoided, however, as it can lead to prolonged suppression
of the bone marrow.
·
Vertebral fractures (fractures in the spine) have traditionally been treated by a procedure called
vertebroplasty, in which cement is injected into the affected vertebrae to stabilize it. A newer alternative
is kyphoplasty. In kyphoplasty, a balloon is inserted into the compressed vertebra and inflated to
raise up the collapsed section. The cavity is then filled with a bone cement, stabilizing the vertebrae
and preserving the reestablished height.
Is exercise safe?
Unless there are reasons why you can not exercise, mild to moderate exercise such as walking or swimming may
be physically and emotionally beneficial. It is important to avoid contact sports or activities that could result in
falls.Talk with a physical therapist or your healthcare team about activities that would be suitable for you.
| Managing Complications and Side Effects

Anemia
By crowding the bone marrow, myeloma can result in a reduced red blood
cell count. Red blood cells are important because they contain hemoglobin.
Hemoglobin carries oxygen from the lungs to the cells of your body, giving
you energy and stamina.
If the hemoglobin count is less than 120 g/L in a women or less than
130 g/L in a man, it is called anemia. Whether anemia requires treatment
will depend upon its level, how quickly the level is changing, and how
well you are feeling and functioning.
Symptoms of anemia include:
·
feeling very tired even though you are getting enough rest
·
looking pale
·
becoming short of breath after even mild exertion
·
finding it hard to do daily chores, to concentrate or to
remember things
·
feeling lightheaded or dizzy
Different people react differently to having a low hemoglobin count. Some people also report headaches,
leg pains or feeling cold.
Why treat anemia? Studies have shown that in people with cancer, treating anemia can help relieve fatigue,
make it easier to do everyday activities, reduce the need for blood transfusion, improve the quality of daily
life and make it more likely they will be able to complete their cancer therapy.
There are a number of treatment options for anemia, and it is important to discuss all of them with your
healthcare team.
If your anemia is due to a change in your diet, eating a healthier diet or taking iron, vitamin B12 or
folic acid (folate) supplements may help. Alwayscheckwithyourdoctororpharmacistbefore
takinganynon-prescription,over-the-counterironorvitaminsupplement,oranyherbal
remedy. Some supplements or remedies can interact with prescription medications.
Managing Complications and Side Effects |

Blood transfusions can be used to treat severe anemia and can quickly increase the hemoglobin level
on a short-term basis.
A medication can be prescribed that stimulates the body to make more red blood cells. Epoetin alfa
(Eprex®) and darbepoetin alfa (Aranesp®) contain versions of the human hormone erythropoietin,
which tells the bone marrow to make more red blood cells. Both drugs are given by subcutaneous
injection (an injection just under the skin).
Infections
Myeloma and some of its treatments can affect the normal production of
antibodies and reduce the white blood cell counts. This can leave a person
susceptible to infections. Someone with this problem may get repeated
infections or illness, especially respiratory infections, or take a long time
to recover from them.
Many infections cannot be prevented, so it important that they be treated
as soon as they develop. Fever or other signs of infection or disease should
be reported promptly to your healthcare team. Antibiotics may be required.
It is important to have a complete dental examination before you begin
any treatment therapy. Because of the increased risk of infection, myeloma
patients may require antibiotics before any dental work.
Reduce your risk
To reduce the risk of infections and illnesses, remember to practice good hand-washing techniques.When in
public places, wash your hands frequently or use a hand sanitizer (the small containers can easily fit into your
pocket or purse). Avoid situations where you may come into contact with people who are ill.
| Managing Complications and Side Effects

Kidney damage
The M-proteins produced by myeloma are cleared from the body in the kidneys.
Over time, the elevated levels of abnormal M-proteins in the blood and
urine can damage the kidneys. This is why renal function is assessed regularly
by creatinine testing of the blood.
The best way of preventing kidney damage (renal disease) is to treat the myeloma
and keep the M-protein levels as low as possible. Sometimes but infrequently
if the renal dysfunction is severe, dialysis may be required.
Drink up!
Drinking lots of fluids can help to flush medications and toxins from your body, maintain normal blood volume
and pressure, lubricate the joints, limit fatigue and help prevent kidney damage. The best single fluid to drink
is water. Gradually increase your intake until you are drinking 2 litres of water a day. Try to limit drinks that
contain caffeine, such as coffee, tea and soft drinks. Caffeine and alcohol increase your urine output and can
lead to dehydration and fatigue.
High blood calcium
As bone is broken down, it releases calcium into the blood stream. If the myeloma is causing a lot of bone
damage, the blood can develop excessively high levels of calcium. This condition is called hypercalcemia.
Hypercalcemia is a complication of myeloma and is treatable. Symptoms can include constipation, increased
frequency of urination, weakness and in extreme cases, confusion.
Hold off on calcium supplements
In people without myeloma, calcium supplements are often recommended for bone health. But if you have
myeloma, never take a calcium supplement without checking with your doctor.Too much calcium in the blood
can be unhealthy.
Managing Complications and Side Effects |

Other blood complications
Myeloma can result in other complications of the blood, although most are relatively rare. If the number of
platelets in the blood drops below a healthy level, normal clotting will be affected. This can lead to bruising
or excessive bleeding.
Some medications, such as thalidomide and lenalidomide (Revlimid®) can also increase the risk of blood
clots in the veins, such as in the legs. Known as deep vein thrombosis (DVT), this can be a potentially
dangerous complication. Blood thinning medications can be prescribed to reduce this risk.
In a small number of people, a high M-protein level can cause the blood to thicken (known as hyperviscosity).
If this occurs, blood flow to the skin, fingers, toes, nose, kidneys or brain can be affected.
Bone pain, nerve pain and neuropathy
There are three main causes of pain for myeloma patients:
·
bone pain
·
nerve damage, often due to compression fractures
·
peripheral neuropathy
The sort of treatment you require will depend upon the cause of the pain,
its severity, and how you respond to different therapies. Other treatments
may be helpful. For example, bone pain may be relieved by radiation or
bisphosphonates, and nerve damage due to compression fractures by
vertebroplasty or kyphoplasty.
There are three broad categories of pain medications:
·
Weak opioids, such as codeine, Percocet®/Percodan® and Oxycet®.
·
Non-steroidal anti-inflammatory drugs (NSAIDs), which include non-prescription medications such
as acetylsalicylic acid (ASA, Aspirin®), ibuprofen (Motrin®, Advil®) and prescription medications such
as the COX II inhibitors (Celebrex®, Mobicox®). NSAIDs can increase the risk of kidney damage and
are usually not encouraged for routine use.
·
Stronger opioids, which come in short-acting forms (meperidine or Demerol®) or slow-acting forms
(MSContin®, OxyContin®).
As always, each individual situation should be discussed with your doctor to evaluate the best treatment options.
0| Managing Complications and Side Effects

Pain medication dependency and addiction
Some myeloma patients hesitate to take opioid medications because they are afraid of addiction. Most healthcare
professionals agree that in someone with no history of dependency or addictions, there is little chance of
developing a true addiction. Physical and psychological dependency can occur and can be handled by decreasing
the dose gradually.
It may take some time to find the right treatment for your pain. Extreme
cases may require treatment by a pain specialist.
Peripheral neuropathy appears to be a side-effect of certain drugs
used to treat myeloma, such as thalidomide, bortezomib (Velcade®)
and vincristine. It usually occurs in the feet, legs, hands or arms and
is very different from bone pain. Characteristics of neuropathic pain include:
·
a painful sensitivity to touch (known as allodynia)
·
the sensation of "electric jolts" or that the pain travels
·
a burning, tight or pulling sensation
·
numbness or a "pins and needles" feeling
These sensations may come on spontaneously without movement or get
worse at night.
Drug-induced neuropathy must be treated differently from bone pain or
nerve damage resulting from spinal compression. First, it may be necessary
to stop or reduce the drug causing the neuropathy. Second, the sorts of
medications used for neuropathic pain are different. Drugs used to treat
neuropathic pain include:
·
some of the older tricyclic antidepressants (amitriptyline, nortriptyline
or desipramine)
·
some anti-convulsant medications (gabapentin, phenytoin, valproic acid or carbamazepine)
A number of unconventional and alternative approaches have been proposed for treating neuropathy but
to date there is no evidence that they are effective.
Managing Complications and Side Effects |

Alternative Therapies
Many vitamins, supplements and herbal therapies can interact with your cancer medications. Before taking
any vitamin, supplement or herbal therapy, talk with your physician and/or your pharmacist.
Osteonecrosis of the jaw (ONJ)
Dental health is very important for myeloma patients. Encourage your dentist
to talk with your oncologist to discuss any special precautions you may
require, especially when receiving treatment. Check to see if your cancer
centre has a dental clinic. Before starting any therapy, have a complete
dental examination.
Osteonecrosis of the jaw (ONJ) is a relatively rare side-effect of long-term
bisphosphonate use in which there is abnormal death (necrosis) of the jaw
bone. A review of patients at one of Canada's largest myeloma centres,
the Princess Margaret Hospital in Toronto, found that 2 % of patients taking
pamidronate developed osteonecrosis. It can occur spontaneously but
appears to be more likely following dental work, particularly traumatic
work such as extractions. The risk of osteonecrosis appears to be higher
among those taking zoledronic acid (Zometa®), compared to pamidronate
(Aredia®).
If you think you may take bisphosphonates in the future, be sure to have a complete dental examination
and all corrective work completed. Once you start taking bisphosphonates, it is recommended that you:
·
practice good oral hygiene to reduce the odds of needing dental care
·
see your dentist regularly to catch problems when they are small
·
avoid extractions and peridontal surgery if possible
·
do not have dental implants
Restorative work such as fillings, bridges and crown and root canals are probably safe, provided wounds
are as small as possible and all rough edges are carefully smoothed.
To reduce the risk of osteonecrosis of the jaw, many cancer centres are changing the way they prescribe
bisphosphonates, either reducing the dose or the length of time for which they are taken.
| Managing Complications and Side Effects

Medication side effects
All prescription medications have intended effects and others that
you may not want, commonly known as side effects. Your healthcare
team, particularly your pharmacist and nurse educator, can explain
what side effects you can expect from the medications you are
prescribed, which ones to report right away, and what can be done
to relieve them.
Common side effects of chemotherapy are:
Nauseaandvomiting--anti-sickness (anti-emetic) drugs can help
to prevent and control nausea and vomiting. Avoiding strong smells
and getting lots of fresh air may also help. Vomiting can dehydrate
you, so it is important to try and keep taking sips of cool drinks.
Hairloss(alopecia) is common with some but not all kinds of chemotherapy. If it occurs,
remember that your hair will grow back once your treatment has finished.
Changesinthemouth--depending upon the type of chemotherapy you are receiving, you may
experience mouth sores, or a sore or dry mouth. Medicines or a special mouthwash can help to
prevent or treat mouth ulcers. When undergoing high dose intravenous chemotherapy (e.g., with
melphalan), sucking on ice chips may help to prevent mouth sores. Keep your teeth clean by regularly
using a soft toothbrush, and try to avoid things that might irritate your mouth, such as spicy, salty or
tangy foods. If you have a sore or dry mouth, avoid food that sticks to the roof of your mouth
(e.g., peanut butter or chocolate) and mouthwashes that contain alcohol. Moisten your food with
gravy or sauces and try drinking through a straw or sucking ice-cubes or frozen treats.
Lossofappetite-- at times over the course of your treatment, you may have no appetite or feel
you cannot face food. To avoid losing weight, try to eat small amounts of food particularly fresh
fruits and vegetables frequently throughout the day. Or if you feel hungry at some parts of the day
and not at others, eat your larger meal when you are hungry. No matter what you eat, be sure to
always drink plenty of fluids.
Managing Complications and Side Effects |

Corticosteroids (steroids) such as dexamethasone and prednisone are frequently used to treat myeloma.
Side effects can include:
Fluid retention and swelling, particularly if you also have congestive heart failure
An increase in blood sugar, which is of concern to people with diabetes or at risk of diabetes
Insomnia
Increased appetite
Indigestion or heartburn speak to your physician about medication to prevent this problem
Hiccups
Blurred vision
Mood or emotional charges, such as depression, mood swings, agitation, anxiety, or even psychosis
Other effects than can develop after long-term use of high dose steroids include the Cushingoid appearance
(weight gain with a "moon face"), osteoporosis or bone loss, and muscle weakness and/or wasting. Fatigue,
depression and cataracts are other potential side effects.
Coping with "`Roid Rage"
Dealing with the diagnosis of cancer is hard for you and your loved ones. The mood changes brought about
by steroids can add to that burden. It is important that you talk with your loved ones and explain the effects
steroids can have on your mood and activity levels. Give them a "heads up" when you will be going on and off
your medication. Family members and friends can help by being supportive and understanding that sometimes
"it's the `roids talking".
| Managing Complications and Side Effects

Depression
Some studies suggest that up to 40% of cancer patients experience depression
or anxiety. As you deal with your disease, periods of feeling "blue" or "down"
are not unusual. After all, you are going through a lot of changes. You may
sometimes feel that you are no longer the person you used to be. Physical
and mental changes may threaten your feeling of self-esteem.
Ifthedepressionlastsformanyweekswithoutrelieforissevere

Talk about your feelings with your doctor, nurse or counsellor. Sometimes
just talking with someone is enough to help. In other cases, medication
can be given to help relieve depression.
Speak with a health professional if you experience five or more of the following symptoms for more than
two weeks:
Feeling sad, anxious, irritable, nervous and/or guilty
Feelings of worthlessness or hopelessness

Chapter 7
Your Healthcare Team
When you were told you have myeloma, you may have felt like you were
alone in the battle of your life. But in reality, there is a whole team of dedicated
professionals who are behind you and ready to help you. They are the members
of your healthcare team. In this section, we'll begin by looking at the roles
played by the different members of your team. Then we'll discuss how
you can optimize your communications with your team members and
become a more informed and active participant in your care.
Family Doctor
When you first became ill, probably the first person you saw was your
family doctor. Your family doctor helped to narrow down the possibilities
of what might be wrong and provided referrals to specialists. Most family
doctors see only a few, if any, myeloma patients in their practices.
Oncologist
A medical oncologist is a physician who specializes in the diagnosis and
treatment of cancer. This doctor may be the key member of your health
care team. He or she will determine your exact diagnosis and, in consultation
with you and other specialists, design your treatment plan.
| Your Healthcare Team

Hematologist
Because myeloma is a cancer of the blood, you may be referred to
a hematologist. A hematologist is a physician who studies, diagnoses and
treats diseases and disorders of the blood. Some hematologists specialize
in blood cancers, whereas other may specialize in other blood problems
such as clotting disorders. This doctor may be the key member of your
healthcare team.
Radiation Oncologist
If you require radiation therapy, you will be referred to a radiation oncologist.
As the name implies, a radiation oncologist is a physician who specializes
in treating cancer with radiation therapy.
Surgical Oncologist
A surgical oncologist is a surgeon who specializes in cancer operations.
For example, if a tumour must be removed, you may be referred to
a surgical oncologist.
Nurse or Nurse Practitioner
Nurses may fill several important roles in your healthcare team.
An oncology nurse is a specially-trained nurse who works closely
with your medical oncologist, hematologist or radiation oncologist to
coordinate your care, oversee your therapy and keep your physicians
informed of any problems you may encounter. Other nurses may
specialize as cancer educators. Nurse practitioners are nurses who
have undertaken additional training in diagnosis and treatment of
medical conditions.
Orthopedic Surgeon
If you require surgery on your bones, muscle or joints, you may be referred
to an orthopedic surgeon.
Your Healthcare Team |

Pharmacist
Your treatment for myeloma will involve many medications, some of which
may be oral and others which may be delivered through an intravenous
line. Whether working in the hospital or the community, pharmacists are
valuable sources of information for patients and care providers. Pharmacists
can help you to understand what different medications are design to do,
how to take them, what effects and side effects to expect, and what to do
if side effects occur.
Dentist
Your dentist is an important but often overlooked member of your healthcare
team. Good oral health is important at all times, and even more so when
you are undergoing myeloma treatment. Infections from the teeth can drain
into the lymph glands in the neck, and if your teeth and gums are not kept
clean large quantities and varieties of bacteria can colonize the gums. These
types of infections are an important and preventable source of problems.
If possible, it is best to identify and treat dental problems before you start
chemotherapy, undergo stem cell transplant, or start taking bisphosphonates.
Generally, the best time to be treated is when your hemoglobin count is
100 or more, platelet count 80 or more, and your neutrophil count 2.0 or
more. Special precautions such as prophylactic antibiotics are probably
required if you have a central line or catheter in place.
Dentists who work at cancer centres are familiar with the special requirements
of myeloma patients, but some community dentists may not be. Speak with
your dentist and clearly outline what drugs you are taking (including intravenous
therapies), where you are in your therapy and what the plans may be for
the future. Encourage him or her to talk with a cancer centre specialist.
| Your Healthcare Team

Registered Dietitian/Nutritionist
Cancer and cancer treatment can make eating difficult. You may find it
difficult to eat enough or to eat the right kinds of food to keep up
your strength. Or some medications can actually increase your appetite,
making it difficult to avoid overeating. The dietitian can help you maintain
the healthiest diet possible throughout the different stages of your treatment.
If you are struggling with nausea, vomiting, anorexia (loss of appetite),
or a dry or sore mouth, your dietitian can suggest foods or drinks to help.
Psychiatrist or Psychologist
A psychiatrist is a physician trained in the diagnosis and management of
mental illness. A psychologist is not a physician, but someone who has
advanced training in counselling and human psychology. Both psychiatrists
and psychologists can be very helpful in dealing with the psychological,
emotional or behavioural problems you may encounter. In addition to
"talk therapy", psychiatrists are licensed to prescribe medication, such as
anti-depressants, if required.
Social Worker or Counsellor
Like a psychologist, a social worker or counsellor can help you deal
with the many emotional changes being diagnosed with myeloma can
bring. In addition, a social worker may be able to help you deal with
some of the practical issues that arise, such as finding out more about
your healthcare coverage.
Clergy or Spiritual Advisor
Some people find that talking with their clergy or spiritual advisor can
be very helpful.
Your Healthcare Team |

Optimizing Communications
As a patient, you have both rights and responsibilities when interacting with the members of your healthcare team.
Rights:
To be treated with respect and courtesy.
To be your own advocate or to bring an advocate with you.
To be kept fully informed and to have things explained to you in language you can understand.
To be informed of all possible treatment options available at your centre or other facilities, including
clinical trials.
To be allowed, and even helped, to obtain a second opinion if you want one.
To be given the opportunity to participate in treatment decision-making, including the right to refuse
any treatment you do not want.
When you ask, to receive copies of your records, such as lab results, X-rays, and test results,
at a reasonable cost (e.g., for the cost of copying).
Responsibilities:
To tell the whole truth and nothing but the truth.
To speak up if you aren't happy or don't understand (it helps to be tactful when doing so).
To try and learn about your condition and treatments so you can share in decision making.
To comply with any mutually acceptable treatment plan.
To treat the members of your healthcare team with respect and courtesy.
As you probably know only too well, most healthcare professionals are very busy. Their time to talk is often
limited. And most healthcare professionals are so used to the medical terms they use that they may forget
that other people do not understand them. Here are some tips for optimizing your communications with
your health care team.
0| Your Healthcare Team

Write down any questions you have as well as any side-effects or symptoms you are experiencing.
Bring these lists or documents with you to your appointment. Give the list to your doctor at
the beginning of your consultation. Don't wait until the end, when the doctor is out of time.
Take notes during your consultation of what your doctor says. Or bring someone with you to take
notes for you. Some patients bring tape recorders to their appointments so that they can easily refer
back to what was discussed.
Ask your doctor if he or she has an assistant or nurse that you can talk to whenever you have questions.
Ask if there are any brochures or other educational material you can take home with you.
Keep your own history of your medical history and treatment. Many patients find it helpful to keep
a binder in which they write down all of their appointments and treatments, who treated them, what
medications they received, and their test results. In Canada, patients by law must be given access to
their medical information if they request it (a reasonable fee may be charged to cover copying costs).
Creating and maintaining your own binder of information will give you a better understanding of
your condition, and may be helpful when dealing with healthcare professionals who are not familiar
with your condition.
Not certain of what to ask? Following are some sample questions for different members of your healthcare team.
For your oncologist, hematologist or radiationoncologist:
-
Who should I contact if I have problems, especially after hours or on weekends? Ask for names
and telephone numbers.
-
What are the results of my tests and what do they mean?
-
What are all my treatment options, which one do you recommend and why do you feel this is
the best approach?
-
Are there clinical trials available at this centre or other centres that I could consider?
-
What should I expect when undergoing treatment?
-
How will we know if the treatment is working?
-
Are there any warning signs or side effects that I should watch out for, and if they occur, whom
should I report them to? Which ones do I need to report immediately?
-
Are there foods, vitamins, supplements or herbal therapies that I should avoid?
-
How often will I require testing or follow-up care?
Your Healthcare Team |

For your surgicaloncologist or orthopedic surgeon:
-
Can you explain my surgical procedure in detail?
-
What should I expect before, during and after surgery? What will
my recovery be like?
-
When do I need to come back for a follow-up visit?
For your cancer nurse or educator:
-
What is your role in my cancer care? Are you the person I should
contact if I have a problem or question?
-
Can you help me find reliable and accurate information on myeloma?
-
What advice can you give me at this stage of my cancer treatment?
-
What sort of activities can you suggest so I can stay as active
as possible? Which activities should I avoid?
For your pharmacist:
-
What is the purpose of this medication? What side effects are likely to occur and which ones
should I report immediately if they occur?
-
Are there vitamins, supplements or herbal remedies that I should avoid while taking this drug?
-
Can you help me set up a system, such as daily pill boxes or blister packs, to ensure I take all
of my medications as prescribed?
For your dentist:
-
Are there any infections or dental problems that should be taken care of before I begin my
myeloma treatment?
-
Are you familiar with the requirements for treating someone with myeloma and/or with a central
line in place?
-
What can I do to reduce the risk of requiring extractions or other traumatic dental work while
undergoing treatment?
| Your Healthcare Team

For your dietitian:
-
I'm finding it difficult to eat. Is there anything you can recommend to help me?
-
I'm going to start a new therapy soon. What do we know about this treatment's effect on appetite,
digestion, etc.? Is there anything you can recommend to reduce its effects?
-
Steroids have increased my appetite and I'm finding it difficult to control my eating. What should I do?
For your psychologist, counsellor or spiritualadvisor:
-
Can you help me better deal with the emotional effects of my diagnosis?
-
My family and loved ones are very upset about my illness. What can I do to help them?
For your social worker:
-
Can you help me and my family to learn ways of coping with the changes brought by my disease?
-
Can you help me figure out what healthcare or other benefits I may be eligible for, such as short
or long-term disability leaves?

Chapter 8
Development, Approval and Reimbursement of
New and Emerging Therapies
For decades, only a very small number of therapies were available for myeloma.
Today, the treatment of myeloma has entered a new and exciting phase.
Research into the underlying cellular and biochemical processes of
the disease is making possible a variety of innovative therapies. In this
chapter, we'll look at how new therapies are developed and the approval
process they must undergo. We'll also look at how new therapies are paid for.
New therapy development
Developing new therapies is a long and very expensive process. A number
of phases of types of studies are required.
1. Pre-Clinical
The research that eventually leads to a new drug or treatment typically
begins in a laboratory. Using the results of research into the basic genetic,
cellular or biochemical processes underlying myeloma, scientists test different
molecules or substances. This research may begin by using cells in a test
tube(in vitro)and if promising, proceed to testing in small animals such
as rats or mice (in vivo). Repeated animal trials are required to establish
that a new agent is safe before it can be tested in any humans. Many
molecules may be studied, but only the most promising will make the leap
from pre-clinical to clinical trials.
| Development, Approval and Reimbursement of New and Emerging Therapies

2. Clinical Trials
Clinical trials are research studies involving people. Because people are
involved, all clinical trials must be reviewed by Health Canada and shown
to be safe. Clinical trials must also be approved by the Ethics Committees
of all participating hospitals. These review processes are in place to protect
the safety of participants. Only those studies that pass these rigorous approval
processes are allowed to recruit patients.
There are four phases or types of clinical trials, and each phase is designed
to answer specific questions.
Phase I
The primary question of a Phase I trial is: "What is the best and safest way
to administer the new therapy?" A Phase I trial usually involves a small
number of volunteers. The testing establishes the optimal dose for the new
agent (enough that it is effective but not so much that it has toxic side
effects), and perhaps the best way to administer it (e.g. orally or intravenously).
A Phase I trial is an essential safety check for the new agent. Only those
agents that are shown to be safe can proceed to the next phase of testing.
Phase II
The primary question of a Phase II trial is: "Does the new agent work in
a selected group of patients?" A Phase II trial typically involves a larger
group of volunteers than a Phase I trial. Volunteers are usually chosen to
reflect a particular type or stage of the disease. The goal is to evaluate how
effective the new therapy is in treating the disease in this type of patient.
Possible side effects are also monitored.
Development, Approval and Reimbursement of New and Emerging Therapies |

Phase III
Only therapies that are effective, safe and have tolerable side effects can
proceed to Phase III testing. Phase III trials are usually the largest, and can
involve hundreds or even thousands of patients at cancer centres around
the world. Patients in a Phase III trial are usually assigned randomly to
either the new therapy (often referred to as the "treatment group") or
the existing therapy ("usual care" or "control" group). If there is no existing
therapy, the new agent may be compared to a placebo ("sugar pill") but
this is seldom necessary in myeloma research. The term "Randomized
Controlled Trial" is derived from the random way in which people are
allocated to either the treatment or control group.
The primary question answered by a Phase III trial is: "Is the new agent
effective, particularly in comparison to the best available existing treatment?"
To ensure expectations don't affect the assignment of people into groups
or the interpretation of the data, Phase III trials are often "blinded". "Blinded"
means the patients do not know which agent they are getting. "Double
blinding" is sometimes used so that neither the patient nor the researcher
knows who is getting the new agent until the study is completed.
Phase IV
A Phase IV trial is sometimes referred to as "post marketing research".
It is research on a drug that has already been approved and is being used
widely. Phase IV trials may be conducted to determine if the drug works
as well in the "real world" as it did under the controlled conditions of
a Phase III clinical trial. It may also be conducted to see if there are any
significant long-term effects of the therapy or whether the drug could be
used for other indications.

You can contribute to myeloma research
As a myeloma patient, you may be able to make an invaluable contribution
to myeloma research and the development of new therapies. Perhaps
you can donate marrow for laboratory research, or can volunteer for
a clinical trial. Speak with your doctor or your healthcare team.
There are both advantages and disadvantages to participating in clinical trials.
The advantages are:
You may gain access to a new therapy that is not available outside
of the trial. If the agent is effective, you will be among the first
patients to benefit.
You will be monitored even more closely and frequently than you
would ordinarily.
You will be helping other patients, now and in the future.
Among the disadvantages to consider:
If you receive the new treatment, it may not turn out to be as effective
as the existing therapy or there may be unexpected side effects.
You may need to be tested more frequently than you would ordinarily.
It is important that you understand all potential risks and benefits before
you agree to join a clinical trial. People who are asked to participate in
a clinical trial must give what is called an informed consent. To do so,
the clinical trial coordinator must give you a written document that explains
in plain language the study protocol or written plan, as well as all potential
risks, benefits and requirements.
Development, Approval and Reimbursement of New and Emerging Therapies |

If you are considering a clinical trial, don't be afraid to ask a lot of questions.
The more you know about a study, the more informed your decision will
be. Some questions you may want to ask include:
- What is the purpose of this study?
- Is it a Phase I, Phase II, Phase III or Phase IV study?
- Has the treatment or therapy been tested before? If so, what were
the results? Were there side effects I should know about?
- Who has reviewed and approved this clinical trial?
- How long will the study last? How long will I be involved?
-
Who will be in charge of my care? Will I be cared for by my own doctor?
-
Where will my treatment take place?
-
How will my safety be monitored during the study?
-
What sort of treatments, tests or procedures should I expect? How do they compare with what
I would receive if I didn't participate?
-
What are the possible short- and long-term risks, side effects and benefits for me? How do these
risks, side effects and benefits compare to those of the usual treatment?
-
If the study requires other medications either as part of the treatment or for side effects will
they be supplied by the study? If not, will they be covered by my private or public drug plan?
-
How might being in the trial affect my daily life? Is there anything my family should know about
the treatment?

The drug approval process in Canada
Just because a new therapy has been shown to be effective in a Phase III
trial doesn't mean that it is automatically available in Canadian hospitals,
clinics or pharmacies. Before a drug can be used in Canada, it must go
through a rigorous approval process by Health Canada. Health Canada
does not look solely at whether a new agent is safe, but at the balance
between risks and benefits.
If the drug company's submission is approved, Health Canada will issue
a Notice of Compliance (NOC) and give the drug a Drug Identification
Number (DIN). This means the company is now allowed to market the new
drug in Canada. In some cases, Health Canada may award a Notice of Compliance
with Conditions (NOC/c). A drug awarded with a NOC/c is given a DIN
but the sponsoring company must agree to special conditions or requirements,
such as for more research or professional and patient education.
Once a new agent is approved for use in Canada, the manufacturer must
make a submission to the national Common Drug Review (CDR) committee.
The Common Drug Review was set up by the federal government to make
recommendations as to whether new drugs should be covered under
provincial formularies the list of medications they will pay for. The hope
was that it would streamline the drug review process and help to encourage
greater consistency across the country.
In reality, most provincial drug plans continue to make their own decisions
as to which medications they will or will not list. As a result, the coverage
of new agents often varies across the country. In some cases, even when
a new agent is added to a formulary, the decision as to whether to pay for
it is made on a case-by-case basis. This special authorization process requires
your physician to write a letter to the drug plan, explaining why you require
this particular medication.
Development, Approval and Reimbursement of New and Emerging Therapies |

Reimbursement of new therapies
There are basically four ways of paying for cancer drugs:
The drug is on the list of approved medications of the government
health insurance drug plan of which you are a member (either as
a general benefit or through a special authorization process).
You have a private drug plan which will pay for the drug in question
(many private plans also have formularies or lists of drugs they
will cover).
You pay for the drug yourself.
If you meet certain financial eligibility criteria, assistance may be
provided by the drug manufacturer.
It may take some research to ensure you have optimal access to new
prescription medications and to minimize your own out-of-pocket costs.
Here are some tips to help you.
Know your health insurance coverage. Some provinces only provide
drug coverage for people who are 65 and older or on social assistance.
But others may have a variety of plans, such as special coverage for
those facing substantive prescription drug costs. Drugs provided
through cancer care centres can also vary from province to province.
Talk with your cancer team social worker or pharmacist or call your
provincial Ministry of Health to learn about all your options.
If you have private health insurance or a drug plan at work, sit down
and carefully review your benefits. If you are employed, meet with
your Human Resources department or union representative to help
you better understand your benefits. Ask your doctor what drugs
you may need in the future, and check to see if your plan covers
them. Try to coordinate the benefits so any portion of a drug cost
that is not paid for by one plan is applied to the next.
Some private insurance plans require that you pay up-front and
then apply for reimbursement. If this is a problem for you (e.g. you
need a very expensive drug), ask your insurance company to allow
your pharmacy to send the bill directly to them.
0| Development, Approval and Reimbursement of New and Emerging Therapies

Don't be afraid to advocate for yourself. For instance, if your employee health plan does not cover
a certain drug, ask your employer or human resources manager if the company can make an exception
in your case. Or ask your employer if they would waive the cap on your drug coverage.
Find someone to work with you to advocate for the drug coverage you need. This someone can be
a family member, for instance, or a friend. This person can help continue to advocate for you even
when you cannot.
If you are refused coverage of a medication you need, appeal. Sometimes the refusal may be the result
of nothing more than faulty paperwork. And sometimes insurance companies will change their mind
if you appeal.
Some pharmaceutical companies have free services that will help you search for coverage of specific
drugs or even supply you with the drug you require. Talk with your cancer care team or search online
to see if you may be eligible for such a program.

Chapter 9
How To Be Your Own Advocate
Being diagnosed with cancer can be overwhelming. You are facing a number
of major life changes. One of the most important things you can do to help
yourself is to become your own advocate.
1. Document your experience
It is important that people with myeloma keep a binder or log with detailed
information on their treatments, test results and consultations. Such a log
can help you to better understand your condition and support your efforts
to act as your own advocate.
The sort of information you may want to collect includes:
Names and contact information for all professionals involved in
your care.
Dates of all appointments, reasons for the appointments and any
outcomes or decisions that were made.
Copies of all test results (blood and urine tests and X-rays).
Dates and details of all treatments you undergo.
Details of all medications you are prescribed (dose, how and when
you are supposed to take them, side effects you are supposed
to report).
Daily reports of any side effects or symptoms you experience during
treatments or while taking medications.
| How To Be Your Own Advocate

If you are experiencing fatigue, try keeping a log of your energy level on a scale of 0 (absolutely
exhausted) to 10 (full of energy) at different points of the day. Keeping a log may help to identify
when you have the most and the least energy, so you can plan your activities accordingly.
A pain log can also extremely helpful in identifying the type of pain you are experiencing and how
it should be treated. At different points of the day, write down how severe your pain is on a scale
ranging from 0 (pain-free) to 10 (the most excruciating pain possible). You might also want to describe
the type of pain, where it is, and whether it moves or changes throughout the day.
Living Well With Cancer Personal Health Journal
This journal is a handy way of keeping track of your appointments, lab results, and other information.To obtain
a copy,contact your healthcare team,your local cancer centre or email,call or write Myeloma Canada.
2. Sort out the type of information or services you need
and identify the appropriate person to address
each need
During your treatment for myeloma, you will have a number of different
needs. Sorting out what these needs are will help you identify the most
appropriate person or organization to address them. For example, your
medical needs are best addressed by your healthcare team; emotional or
spiritual needs by a social worker, counsellor, clergy or spiritual advisor;
personal issues such as housekeeping and transportation by your family;
or job-related and/or financial issues by your employer, accountant or lawyer.
How To Be Your Own Advocate |

3. Prepare for each appointment
We prepare for all the important events of our life, such as job interviews,
presentations, weddings and celebrations. Your medical appointments are
equally important, so be sure to prepare for them too.
Keeping your myeloma record will be a big help in preparing for your
medical appointments. A quick review of your record may help to clarify
in your mind what sorts of questions you should ask.
During most medical appointments, things happen so quickly that it can
be difficult to remember what you meant to ask. Don't take chances come
with your list of questions and give it to the healthcare professional at
the beginning of your appointment. If there isn't enough time to cover all
of the questions on your list, ask if you can book another appointment so
you can address them or if there is someone else on your cancer care team
who can talk with you.
4. Take, review and store notes of your visits
During appointments and treatments you will probably be given a lot of
information. Don't expect that you will be able to accurately remember
everything. Bring a notepad with you and take notes during your appointment
and as you talk with different members of your healthcare team. Or bring
a tape recorder and record the appointment. Don't be afraid to ask questions,
especially if someone uses unfamiliar terms. If you want, bring someone
with you to take notes for you or to help you make a record of your visit.
Review these notes when you get home and call your healthcare team
contact if anything is unclear to you. Add these notes to your permanent
record or binder.
| How To Be Your Own Advocate

5. Educate yourself
While it may be overwhelming at the beginning, it is important to educate
yourself about myeloma and about your own condition. Ask your healthcare
team for literature and brochures to read. Consult reputable web sites, such as
those we describe below. Ask at your cancer care treatment centre about support
groups in your area, or consult the listing on the Myeloma Canada website.
6. Involve others
Support is essential when you are living with myeloma. There are various
ways in which different people can help. Some may be able to offer
emotional support. Others may give practical support, such as running
errands or driving you when you are not feeling well.
When you feel too tired or ill to act as your advocate, it can be very helpful
to have someone who can step in and take over this role for you. Whether
going with you to your appointment, taking notes, or asking questions,
having someone to advocate for you can be extremely helpful.
Finally, don't forget to look for patient support groups in your area. Patient
support groups can be valuable sources of information and support. Many
arrange for talks by healthcare providers, or can give you access to resources
such as brochures or booklets. Ask at your hospital or cancer centre if
there is a myeloma patient support group in your area, or check the Myeloma
Canada website. If there is no group in your area, consider forming one.
Myeloma Canada will give you information and support on how to start
a patient group in your area.

Your Journey Has Begun
In this handbook, we have covered a lot of material. Don't expect to be
able to understand or remember all of it. Focus your attention on those
parts that are most relevant to your situation at this time. Come back
whenever you have questions, are unclear about something, or want to
learn more.
Hundreds of years ago, explorers set sail uncertain of where they would
end up or what they would encounter. Being diagnosed with a disease
such as myeloma is similar in many ways. The life and world you have
known has changed, and you are embarking on a journey in a new and
often unfamiliar world. Sometimes it may seem overwhelming and frightening.
But there are people to help and support you. Some of them are in your
home and community; others are at your hospital, cancer clinic or place
of worship.
The journey you are facing is challenging. The outcome is uncertain.
But remember that you are never alone. Around the world, patient groups,
healthcare professionals and researchers are working hard to improve
the outlook for myeloma patients everywhere.
| Your Journey Has Begun

Glossary
Accrual: The process of enrolling patients in a clinical research study (trial), or the number of patients already enrolled
in a trial or anticipated to enroll in a trial.
Acute: A sudden onset of symptoms or disease.
Albumin: Simple water-soluble proteins that are found in blood serum.
Alkylating agent: A chemotherapeutic agent such as melphalan or cyclophosphamide. Alkylating refers to the way
in which these agents cross-link the DNA of myeloma cells and block cell division.
Allogeneic: See "Transplantation"
Amyloidosis: A condition in which myeloma light chains (Bence-Jones proteins) are deposited in tissues and organs
throughout the body. This occurs more commonly with lambda versus kappa Bence-Jones proteins. In patients with
amyloidosis, the light chain proteins bind to certain tissues such as heart, nerves and kidney rather than being
excreted out of the body through the kidneys.
Analgesic: Any drug that relieves pain. Aspirin and acetaminophen are mild analgesics.
Analogue: A chemical compound that is structurally similar to another but differs slightly in composition.
Anemia: A decrease in the normal number of red blood cells. Myeloma in the bone marrow blocks red blood cell
production, causing shortness of breath, weakness, and tiredness.
Angiogenesis: Blood vessel formation, which usually accompanies the growth of malignant tissue, including myeloma.
Angiogenesis inhibitors: Compounds that attempt to cut off the blood supply to tumours.
Antibody: A protein produced by certain white blood cells (plasma cells) to fight infection and disease in the form
of antigens such as bacteria, viruses, toxins or tumours. Each antibody can bind only to a specific antigen.
The purpose of this binding is to help destroy the antigen. Antibodies can work in several ways, depending on the
nature of the antigen. Some antibodies disable antigens directly. Others make the antigen more vulnerable to
destruction by other white blood cells.
Anti-emetic agent: A drug that prevents or controls nausea and vomiting.
Antigen: Any foreign substance (such as a bacteria, virus, toxin or tumour) that, when introduced into or arising in
the body, causes the immune system to produce natural antibodies.
Antineoplastic agent: A drug that prevents, kills, or blocks the growth and spread of cancer cells.
Glossary |

Apoptosis: A normal cellular process involving a genetically programmed series of events leading to the death of a cell.
Aspiration: The process of removing fluid or tissue, or both, from a specific area.
Asymptomatic myeloma: Myeloma that presents no signs or symptoms of disease. Also called indolent, smoldering,
or early myeloma.
B cells: White blood cells that develop into plasma cells in the bone marrow and are the source of antibodies. Also
known as B lymphocytes.
Basophil: A type of white blood cell. Basophils are granulocytes.
Bence-Jones: A myeloma protein present in urine. The amount of Bence-Jones protein is expressed in terms of grams
per 24 hours. Normally a very small amount of protein (< 0.1 g/24 h) can be present in the urine, but this is albumin
rather than Bence-Jones protein. The presence of any Bence-Jones protein is abnormal.
Benign: Not cancerous; does not invade nearby tissue or spread to other parts of the body. MGUS is a benign condition.
Beta 2 microglobulin (2M): A small protein found in the blood. High levels occur in patients with active myeloma.
Low or normal levels occur in patients with early myeloma and/or inactive disease. Approximately 10 % of patients
have myeloma that does not produce 2M. For these patients, 2M testing cannot be used to monitor the disease.
At the time of relapse, 2M can increase before there is any change in the myeloma protein level. Therefore, 90 % of
the time, 2M is very useful for determining disease activity.
Biopsy: The removal of a sample of tissue for microscopic examination to aid in diagnosis.
Bisphosphonate: A type of drug that binds to the surface of bone where it is being resorbed (or destroyed) and protects
against osteoclast activity.
Blood cells: Minute structures produced in the bone marrow; they include red blood cells, white blood cells and platelets.
Blood count: The number of red blood cells, white blood cells and platelets in a sample of blood.
Bone marrow: The soft, spongy tissue in the center of bones that produces white blood cells, red blood cells and platelets.
Bone marrow aspiration: The removal, by a needle, of a sample of fluid and cells from the bone marrow for examination
under a microscope.
Bone marrow biopsy: The removal, by a needle, of a sample of tissue from the bone. The cells are checked to see
whether they are cancerous. If cancerous plasma cells are found, the pathologist estimates how much of the bone
marrow is affected. Bone marrow biopsy is usually done at the same time as bone marrow aspiration.
Bone remodelling: The normal coordination (coupling) between osteoclast cells (which resorb or destroy bone) and
osteoblast cells (which create new bone matrix) to maintain a balanced state of bone production and destruction.
Calcium: A mineral found mainly in the hard part of bone matrix.
Cancer: A term for diseases in which malignant cells divide without control. Cancer cells can invade nearby tissues
and spread through the bloodstream and lymphatic system to other parts of the body.
Carcinogen: Any substance or agent that produces or stimulates cancer growth.
CAT or CT [Computerized (Axial) Tomography scan]: A test using computerized X-rays to create three-dimensional images
of organs and structures inside the body, used to detect small areas of bone damage or soft tissue involvement.
Catheter: A tube that is placed in a blood vessel to provide a pathway for drugs or nutrients. The catheter allows
medications, fluids, or blood products to be given and blood samples to be taken.
0| Glossary

Cell differentiation: The process during which young, immature (unspecialized) cells take on individual characteristics
and reach their mature (specialized) form and function.
Cell proliferation: An increase in the number of cells as a result of cell growth and cell division.
Chemotherapy: The treatment of cancer with drugs that kill all rapidly-dividing cells.
·
Combination chemotherapy The use of more than one drug given in a chemotherapy regimen during cancer treatment.

the transmission of genetic information. Normally, human cells contain 46 chromosomes.
Chronic: Persisting over a long period of time.
Clinical: Involving direct observation of a patient.
Clinical trial: A research study of new treatment that involves patients. Each study is designed to find better ways to
prevent, detect, diagnose or treat cancer and to answer scientific questions.
·
Control group The arm of a randomized clinical trial that gets the standard treatment.
·
End Point What a clinical trial is trying to measure or find out; the goal of the trial. Typical end points include
measurements of toxicity, response rate and survival.
·
Experimental group The arm of a randomized trial that gets the new treatment.
·
Randomized clinical trial A research study in which subjects are randomly assigned to receive a particular treatment.
Creatinine: A small chemical compound normally excreted by the kidneys. If the kidneys are damaged, the serum
level of creatinine builds up, resulting in an elevated serum creatinine. The serum creatinine test is used to measure
kidney function.
Cytokine: A substance secreted by cells of the immune system that stimulates growth/activity in a particular type of
cell. Cytokines are produced locally (i.e., in the bone marrow) and circulate in the bloodstream.
Dexamethasone: A powerful corticosteroid given alone or with other drugs.
Diagnosis: The process of identifying a disease by its signs and symptoms.
Dialysis: When a patient's kidneys are unable to filter blood, the blood is cleaned by passing it through a dialysis machine.
DNA: The substance of heredity; a large molecule that carries the genetic information that cells need to replicate and
to produce proteins.
Drug resistance: The result of cells' ability to resist the effects of a specific drug.
Edema: Swelling; an abnormal accumulation of fluid in part of the body.
Electrophoresis: A laboratory test in which a patient's serum (blood) or urine molecules are subjected to separation
according to their size and electrical charge. For myeloma patients, electrophoresis of the blood or urine allows both
the calculation of the amount of myeloma protein (M-protein) as well as the identification of the specific M-spike
characteristic for each patient. Electrophoresis is used as a tool both for diagnosis and for monitoring.
Enzyme: A substance that affects the rate at which chemical changes take place in the body.
Erythrocytes: Red blood cells (RBCs). RBCs carry oxygen to body cells and carbon dioxide away from body cells.
Erythropoietin: A hormone produced by the kidneys. Myeloma patients with damaged kidneys don't produce enough
erythropoietin and can become anemic. Injections with synthetic erythropoietin can be helpful. Blood transfusion is
another alternative, especially in an emergency.
Glossary |

Free light chains: A portion of the monoclonal protein of light molecular weight that can be measured in a sensitive
assay, the Freelite® test.
Gene: A specific sequence of DNA or RNA; the biological unit of heredity located in a specific place on a chromosome
and found in all cells in the body. When genes are missing or damaged, cancer may occur.
Gene therapy: Treatment that alters genes; using genes to stimulate the immune system. In studies of gene therapy for
cancer, researchers are trying to improve the body's natural ability to fight the disease and to make the tumour more
sensitive to other kinds of therapy. Treatment focuses on replacing damaged or missing genes with healthy copies.
Genetic: Inherited; having to do with information that is passed from parents to children through DNA in the genes.
Graft-versus-host disease (GVHD): A reaction of donated stem cells against the recipient's own tissue.
Granulocyte: A type of white blood cell that kills bacteria. Neutrophils, eosinophils, and basophils are granulocytes.
Hematocrit (Hct): The percentage of red blood cells in the blood. A low hematocrit measurement indicates anemia.
Hematologic: Originating in the blood, or disseminated by the circulation or through the bloodstream.
Hematologist: A doctor who specializes in the problems of blood and bone marrow.
Herpes simplex: A common virus, it causes sores often seen around the mouth, commonly called cold sores.
Herpes zoster: A virus that settles around certain nerves in patients who have previously had a chicken pox (varicella)
infection, causing blisters, swelling, and pain. This condition is also called shingles.
Hormones: Chemicals produced by various glands of the body that regulate the actions of certain cells or organs.
Human leukocyte antigen (HLA) test: A blood test used to match a blood or bone marrow donor to a recipient for transfusion
or transplant.
Hypercalcemia: A higher-than-normal level of calcium in the blood. This condition can cause a number of symptoms,
including loss of appetite, nausea, thirst, fatigue, muscle weakness, restlessness and confusion. Common in myeloma patients
and usually resulting from bone destruction with release of calcium into the blood stream. Often associated with reduced
kidney function since calcium can be toxic to the kidneys. For this reason, hypercalcemia is usually treated on an emergency
basis using IV fluids combined with drugs to reduce bone destruction along with direct treatment for the myeloma.
IgG, IgA: The two most common types of myeloma. The G and the A refer to the type of protein produced by the myeloma
cells. The myeloma protein, which is an immunoglobulin, consists of two heavy chains, (for example of a G type) combined
with two light chains, which are either kappa or lambda. Therefore, the two most common subtypes of myeloma have
identical heavy chains (i.e. IgG kappa and IgG lambda). The terms heavy and light refer to the size or molecular weight of
the protein, with the heavy chains being larger than the light chains. Since the light chains are smaller, they are more likely
to leak out into the urine, resulting in Bence-Jones protein.
IgD, IgE: Two types of myeloma that occur less frequently.
IgM: Usually associated with Waldenstrom's macroglobulemia. In rare cases can be a type of myeloma.
Immune system: The complex group of organs and cells that produces antibodies to defend the body against foreign
substances such as bacteria, viruses, toxins and cancers.
Immunodeficiency: A lowering of the body's ability to fight off infection and disease.
Immunofixation: An immunologic test of the serum or urine used to identify proteins in the blood. For myeloma
patients, it enables the doctor to identify the M-protein type (IgG, IgA, kappa, or lambda). The most sensitive routine
immunostaining technique, it identifies the exact heavy and light chain type of M-protein.
| Glossary

Immunoglobulin (Ig): A protein produced by plasma cells, an essential part of the body's immune system. Immunoglobulins
attach to foreign substances (antigens) and assist in destroying them. The classes of immunoglobulins are IgA, IgG,
IgM, IgD and IgE.
Immunosuppression: Weakening of the immune system that causes a lowered ability to fight infection and disease.
Immunosuppression may be deliberate, such as in preparation for bone marrow transplantation to prevent rejection
by the host of the donor tissue, or incidental, such as often results from chemotherapy for the treatment of cancer.
Immunotherapy: Treatment that stimulates the body's natural defenses to fight cancer. Also called biological therapy.
Incidence: The number of new cases of a disease diagnosed each year.
Induction therapy: The initial treatment used in an effort to achieve remission in a newly diagnosed myeloma patient.
Also referred to as "front-line" or "first-line" therapy.
Informed consent: The process requiring a doctor to give a patient enough information about a proposed procedure
for the patient to make an informed decision about whether or not to undergo it. The doctor must, in addition to
explaining all procedures, address the issues of risks, benefits, alternatives and potential costs.
Infusion: Delivering fluids or medications into the bloodstream over a period of time.
Injection: Pushing a medication into the body with the use of a syringe and needle.
Interferon: A naturally produced hormone (cytokine) released by the body in response to infection or disease which
stimulates the growth of certain disease-fighting blood cells in the immune system.
Interleukin: A naturally produced chemical released by the body or a substance used in biological therapy. Interleukins
stimulate the growth and activities of certain kinds of white blood cells. Interleukin-2 (IL-2) is a type of biological
response modifier that stimulates the growth of certain blood cells in the immune system that can fight some types of
cancer. Interleukin-6 (IL-6) is a cytokine which is a potent stimulus to osteoclast and plasma cell activities.
LDH: Lactate dehydrogenase, an enzyme that may be used to monitor myeloma activity.
Lesion: An area of abnormal tissue change. A lump or abscess that may be caused by injury or disease, such as cancer.
In myeloma, "lesion" can refer to a plasmacytoma or a hole in the bone.
Leukocytes: Cells that help the body fight infections and other diseases. Also called white blood cells (WBCs).
Leukopenia: A low number of white blood cells.
Lymphocytes: White blood cells that fight infection and disease.
Lytic lesions: The damaged area of a bone that shows up as a dark spot on an X-ray when enough of the healthy bone in
any one area is eaten away. Lytic lesions look like holes in the bone and are evidence that the bone is being weakened.
M proteins (M spike): Antibodies or parts of antibodies found in unusually large amounts in the blood or urine of multiple
myeloma patients. M spike refers to the sharp pattern that occurs on protein electrophoresis when an M protein is present.
Synonymous with monoclonal protein, paraprotein and myeloma protein. (See "monoclonal" below)
Maintenance therapy: Drugs given to patients in remission to delay or prevent a relapse.
Melanoma: A cancer of the pigment-forming cells of the skin or the retina of the eye. Not associated with myeloma
despite the similar-sounding name.
Metastasize: To spread from one part of the body to another. When cancer cells metastasize and form secondary tumours,
the cells in the metastatic tumour are like those in the original (primary) tumour. This term is commonly used to describe
a disease process in solid tumours (e.g., breast, prostate) and not in myeloma, which is a blood-related cancer.
Glossary |

MGUS (Monoclonal Gammopathy of Undetermined Significance): A benign condition in which the M protein is present
but there is no underlying disease.
Monoclonal: A clone or duplicate of a single cell. Myeloma develops from a single malignant plasma cell (monoclone).
The type of myeloma protein produced is also monoclonal; a single form rather than many forms (polyclonal). The important
practical aspect of a monoclonal protein is that it shows up as a sharp spike (M spike) in the serum electrophoresis test.
Monoclonal antibodies: Artificially manufactured antibodies specifically designed to find and bind to cancer cells for
diagnostic or treatment purposes. They can be used alone, or they can be used to deliver drugs, toxins, or radioactive
material directly to tumor cells.
Monocyte: A type of white blood cell.
MRI (Magnetic Resonance Imaging): A diagnostic test that uses magnetic energy, rather than X-ray energy, to produce
detailed two- or three-dimensional images of organs and structures inside the body. Gives very fine resolution of soft
tissues, especially encroachments on the spinal cord, but is less accurate for bone lesions.
Myelosuppression: A decrease in the production of red blood cells platelets and some white blood cells by the bone marrow.
Neutropenia: A reduced level of neutrophils. Cytotoxic chemotherapy has a tendency to induce neutropenia. In contrast,
lymphocytes which are more important in viral infections, tend not to be affected by cytotoxic treatment. Neutropenia
can be prevented or reduced using a synthetic hormone called G-CSF (e.g. Neupogen®).
Neutrophil: A type of white blood cell necessary to combat bacterial infection.
Oncogene: A gene that has the potential to cause a normal cell to become cancerous.
Oncologist: A doctor who specializes in treating cancer. Some oncologists specialize in a particular type of cancer treatment.
Osteoblast: The cell that produces osteoid, which becomes mineralized with calcium to form new hard bone.
Osteoclast: A cell found in the bone marrow at the junction between the bone marrow and the bone that resorbs or
breaks down old bone. In myeloma, the osteoclasts are over-stimulated while osteoblast activity is blocked. The combination
of accelerated bone resorption and blocked new bone formation results in lytic lesions.
Osteonecrosis of the jaw: A previously rare jaw problem now being observed in a small percentage of patients taking
bisphosphonates. The condition produces pain, swelling, and bone damage around the tooth sockets in the jaws. There
is bone necrosis or loss of bone which can lead to loose teeth, sharp edges of exposed bone, bone spurs and the breaking
loose of small bone spicules or dead bone. A case definition is 3 months with non-healing exposed bone. Symptoms
may not be obvious at first, or may include pain, swelling, numbness or a "heavy jaw" feeling, or loosening of a tooth.
Osteoporosis: Reduction in bone density typically associated with old age. Diffuse involvement of bones with myeloma
produces what looks like osteoporosis on X-ray and bone density measurement.
Palliative treatment: Aimed to improve the quality of life by relieving pain and symptoms of disease but not intended
to alter its course.
Pathological fracture: A break in a bone usually caused by cancer or some disease condition. Occurs in myeloma-
weakened bones, which can't bear normal weight or stress.
PET (Positron Emission Tomography) scan: A diagnostic test that uses a sophisticated camera and computer to produce
images of the body. PET scans show the difference between healthy and abnormally functioning tissues.
Placebo: An inert (inactive) substance often used in clinical trials for comparison with an experimental drug.
Plasma: The liquid part of the blood in which red blood cells, white blood cells and platelets are suspended.
| Glossary

Plasma cells: Special white blood cells that produce antibodies. The malignant cell in myeloma. Normal plasma cells
produce antibodies to fight infection. In myeloma, malignant plasma cells produce large amounts of abnormal antibodies
that lack the capability to fight infection. The abnormal antibodies are the monoclonal protein, or M protein. Plasma cells
also produce other chemicals that can cause organ and tissue damage (i.e. anemia, kidney damage and nerve damage).
Plasmacytoma: A collection of plasma cells found in a single location rather than diffusely throughout the bone marrow,
soft tissue, or bone.
Plasmapheresis: The process of removing certain proteins from the blood. Plasmapheresis can be used to remove
excess antibodies from the blood of multiple myeloma patients.
Platelet: One of the three major blood elements, others being the red blood cells and white blood cells. Platelets are
the major defense against bleeding. Also called thrombocytes.
Port - Implanted: A catheter connected to a quarter-sized disc that is surgically placed just below the skin in the chest
or abdomen. The catheter is inserted into a large vein or artery directly into the bloodstream. Fluids, drugs, or blood
products can be infused, and blood can be drawn through a needle that is stuck into the disc.
Prognosis: The projected outcome or course of a disease; the chance of recovery; the life expectancy.
Progression-free survival: The time period during which the patient survives and the cancer does not become worse.
The improved survival of a patient that can be directly attributed to the treatment given for the myeloma. This term identifies
myeloma patients who are in complete remission versus those who have had an episode of relapse or progression.
Progressive disease: Disease that is becoming worse, as documented by tests.
Protocol: A detailed plan of treatment including the dose and schedule of any drugs used.
Precancerous: A term used to describe a condition that may, or is likely to become, cancer.
Radiation therapy: Treatment with X-rays, gamma rays, or electrons to damage or kill malignant cells. The radiation may come
from outside the body (external radiation) or from radioactive materials placed directly in the tumour (implant radiation).
Radiologist: A doctor who specializes in creating and interpreting images of areas inside the body. The images are produced
with X-rays, sound waves, magnetic fields, or other types of energy.
Recurrence: The reappearance of a disease after a period of remission.
Red blood cells (erythrocytes): Cells in the blood that contain hemoglobin and deliver oxygen to and take carbon dioxide
from all parts of the body. Red cell production is stimulated by a hormone (erythropoietin) produced by the kidneys.
Myeloma patients with damaged kidneys don't produce enough erythropoietin and can become anemic. Injections with
synthetic erythropoietin can be helpful. Blood transfusion is another alternative, especially in an emergency.
Refractory: Disease that is unresponsive to standard treatments.
Regression: The shrinkage of cancer growth.
Relapse: The reappearance of signs and symptoms of a disease after a period of improvement.
Remission or response: Complete or partial disappearance of the signs and symptoms of cancer. Remission and response
are used interchangeably.
Shingles: See "Herpes zoster"
Side effects: Problems that occur due to drugs used for disease treatment. Common side effects of cancer chemotherapy
are fatigue, nausea, vomiting, decreased blood cell counts, hair loss and mouth sores.
Skeletal survey (metastatic survey): A series of plain X-rays of the skull, spine, ribs, pelvis and long bones to look for
lytic lesions and/or osteoporosis.
Glossary |

Stable disease: This describes patients who have some response to treatment but < 50 % reduction in myeloma protein
levels. Stable disease is not necessarily bad or sub-optimal provided the myeloma has stabilized and is not progressing.
With slow-moving myeloma, stabilization can last for many years.
Stage: The extent of a cancer in the body.
Staging: Doing exams and tests to learn the extent of the cancer in the body.
Stem cells: The immature cells from which all blood cells develop. Normal stem cells give rise to normal blood
components, including red cells, white cells and platelets. Stem cells are normally located in the bone marrow and
can be harvested for transplant.
Steroid: A type of hormone. Steroids are often given to patients along with one or more anticancer drugs and appear
to help to control the effects of the disease on the body.
Supportive care: Treatment given to prevent, control, or relieve complications and side effects and to improve the patient's
comfort and quality of life.
Thrombocyte: See "Platelet"
Thrombocytopenia: A low number of platelets in the blood. The normal level is 150,000-450,000. If the platelet count is less
than 50,000, bleeding problems could occur. Major bleeding is usually associated with a reduction to less than 10,000.
TNF (Tumor Necrosis Factor): A type of biological response modifier that can improve the body's natural response to disease.
Transfusion: The transfer of blood or blood products.
Transplantation: The use of stem cells are to rescue a patient's blood-forming potential following high-dose chemotherapy
and/or radiation treatment. Transplant is not a treatment, but a method of support to make high-dose treatment possible.
·
Bone marrow transplantation This term refers to the process of collecting stem cells from the bone marrow
and infusing them into a patient. This term is used less frequently today in myeloma as stem cells are now
collected from the peripheral or circulating blood.
·
Peripheral blood stem cell transplantation Doctors remove healthy stem cells from a patient's circulating blood
system (not from the bone marrow) and store them before the patient receives high-dose chemotherapy to
destroy the cancer cells. The stem cells are then returned to the patient, where they can produce new blood
cells to replace cells destroyed by the treatment.
·
Allogeneic The infusion of bone marrow or stem cells from one individual (donor) to another (recipient).
A patient receives bone marrow or stem cells from a compatible, though not genetically identical, donor.
·
Autologous A procedure in which stem cells are removed from a patient's blood and then are given back to
the patient following intensive treatment.
·
Matched unrelated donor transplants (MUDs) Refers to stem cell transplantation procedures in which
the patient and the stem cells are genetically matched but are not from family members.
·
Syngeneic The infusion of bone marrow or stem cells from one identical twin into another.
Tumour: An abnormal mass of tissue that results from excessive cell division. Tumours perform no useful body function.
They may either be benign or malignant.
Tumour marker: A substance in blood or other body fluids that may suggest that a person has cancer.
Vaccine: A preparation of killed microorganisms, living attenuated organisms, or living fully virulent organisms that is
administered to produce or artificially increase immunity to a particular disease.
| Glossary

Waldenstrom's macroglobulemia: A rare type of indolent lymphoma that affects plasma cells. Excessive amounts of
IgM protein are produced. Not a type of myeloma.
White blood cells (WBC): General term for a variety of cells responsible for fighting invading germs, infection and
allergy-causing agents. These cells begin their development in the bone marrow and then travel to other parts of
the body. Specific white blood cells include neutrophils, granulocytes, lymphocytes, and monocytes.
X-ray: High-energy electromagnetic radiation used in low doses to diagnose diseases and in high doses to treat cancer.
