Multiple MyelomaStaging and Prognosis
![Page 3: Scottsdale, Arizona Rochester, Minnesota Jacksonville, Florida Multiple Myeloma Monitoring and Therapy Angela Dispenzieri, M.D. IMF Patient Workshop November](https://reader038.vdocuments.us/reader038/viewer/2022110320/56649ccc5503460f94995a5e/html5/thumbnails/3.jpg)
Myeloma Staging Systems
• Durie Salmon: IA-IIIB• Size of M-protein, extent of anemia,
calcium, kidney function, and number of bone lesions
• International staging system: I-III• Blood albumin and beta-2
microglobulin
![Page 4: Scottsdale, Arizona Rochester, Minnesota Jacksonville, Florida Multiple Myeloma Monitoring and Therapy Angela Dispenzieri, M.D. IMF Patient Workshop November](https://reader038.vdocuments.us/reader038/viewer/2022110320/56649ccc5503460f94995a5e/html5/thumbnails/4.jpg)
Most Important Prognostic Factors
• Age• Frailty• Renal function• Myeloma stage• Myeloma cells
• FISH (fluorescent in situ hybridization) of myeloma cells
• Aberrant flow phenotype • Gene expression profiling

What do we mean by ‘prognostic’ factors?
• Different patients’ myeloma acts almost like different diseases!
• Markers to help differentiate those patients with the ‘gentlest’ myeloma from those with the ‘meanest’ myeloma

What tests should be done with new diagnosis of multiple myeloma?
1. Protein electrophoresis of blood and urine and quantitative immunoglobulin
2. Serum immunoglobulin free light chain
3. Blood hemoglobin, creatinine, calcium, albumin, beta-2 microglobulin, and LDH
4. Bone radiographs
5. Bone marrow aspirate with FISH and immunophenotype
Prognostic factor
Important to monitor for complications and to establish response therapy

Survival for MM patients has doubled to tripled past 15
years due to new treatments!

The landscape is changing for patients with myeloma thanks
to investigators all over the world and patients like you,
who are willing to participate in clinical trials.
