23. Multiple myeloma is a hematological (blood) cancer that
develops in the plasma cells found in the bone marrow.
Risk factors :
genetic factors
prevalence of MGUS
(About 19% of MGUS patients develop multiple myeloma in
about two to 19 years after MGUS diagnosis).
occupational exposure
Radiation
Age, race, and gender.
24. Symptoms
• Bone pain or bone fractures
• Fatigue
• Increased vulnerability to infections
• Increased or decreased urination
• Restlessness – eventually followed by extreme weakness and fatigue
• Confusion
• Increased thirst
• Nausea and vomiting
• Loss of appetite and weight loss
• Impaired kidney function
25. Diagnostic Criteria
The diagnostic criteria for multiple myeloma requires confirmation of one major and
one minor criteria or three minor criteria in an individual who has signs or symptoms of
multiple myeloma.
Major criteria
-Plasmacytoma (as
demonstrated on evaluation
of biopsy specimen)
-30% plasma cells in a bone
marrow sample
-Elevated levels of M protein
in the blood or urine
Minor criteria
-10% to 30% plasma cells in a bone
marrow sample.
-Minor elevations in the level of M
protein in the blood or urine.
-Osteolytic lesions (as demonstrated on
imaging studies).
-Low levels of antibodies (not produced
by the cancer cells) in the blood.
26. Classifying Multiple Myeloma
.11.Monoclonal gammopathy of undetermined significance
(MGUS)
2. Asymptomatic myeloma (further subdivided into smoldering
myeloma or indolent myeloma)
3. Symptomatic myeloma
27. Diagnostic Tests
CBC , Albumin , Ca , LDH
IgG or IgA antibodies
Serum protein electrophoresis : Monoclonal or M protein
Immunofixation electrophoresis
Freelite™ serum free light chain (FLC) assay
Urinalysis
Urine protein level
X-ray
Bone marrow biopsy/aspiration
Cytogenetic analysis(also known as karyotyping and Fluorescence In Situ
Hybridization [FISH])
