Why do we use bone markers for the assessment
di
and mon tit i
or ng MM
MM bone di
di
?
sease
· Bone lesions do not normally heal even if MM
goes into remission (osteoblast dysfunction).
· Radiographs frequently do not indicate
increased bone resorption in MM progression.
· BMD measurements are often not informative for
bone disease status in MM.
· Bi
Bioch
i
em cal markers f

tabo ilism have
been used in an effort to better monitor the
myeloma bone disease and improve
assessment of disease progression.

Due to bone specificity and their unique
characteristics NTX, ICTP, and CTX have almost
totally replaced the use of older resorption indices
in the diagnostic assessment of bone diseases.

Zoledronic Acid increases serum Osteoprotegrin
in early stage
-
Multiple Myeloma
Methods
· Pilot study comparing OPG, RANKL, and MIP-1 levels in patients
with stage IA MM with healthy patients
Results
· Patients with smoldering MM (n = 26) had significantly decreased
OPG levels (P < .05) and increased RANKL/OPG ratios
· Patients treated with zoledronic acid (n = 16) had increased levels
of OPG, decreased RANKL/OPG ratios and a 3.8% increase in BMD
(P < .05)
Conclusion
· Zoledronic acid increases levels of OPG, decreases RANKL/OPG
ratio, and increases BMD in patients with MM
Martini et al, Haematologica 2006;91:1720-1
Conclusions for Bone Markers in MM
· Biochemical markers of bone turnover and osteoclast function
reflect the
the extent of bone disease in
in MM
MM
(NTX, ICTP > CTX >DPD & PYD)
· NTX and ICTP correlates with SREs and disease progression
pg
· NTX is an independent prognostic factor for survival
· There is a dichotomy regardin
yg
g the pro
p gnostic
g
value of bALP
that depends on disease stage
· May be useful in monitoring bisphosphonate treatment
· Chemotherapeutic and novel anti-myeloma agents affect
levels of bone markers in patients with multiple myeloma
· Marker (NTX)-related therapy ?
· Novel markers (RANKL, OPG) need further evaluation
Side-effects of bisphosphonates

· The risk seems to be higher when zoledronic acid

Conclusions (2)
· Although the association of ONJ with the use of
bisphosphonates seems well established, several
issues need to be clarified:
the pathophysiological mechanism
Other possible risk factors,
prevention and appropriate treatment.
· The diagnosis of ONJ, in most cases, has been made
retrospectively based on the review of medical records
rather than by a specialist

· Further studies are needed to establish the time for
