Overview
If left untreated, most of patients with multiple myeloma may progress to develop fatigue, bone pain, and pallor.[1] Complications that can develop as a result of multiple myeloma are hematologic complication, renal failure,skeletal, and neurological complications.[2] The prognosis of multiple myeloma is good with treatment. Without treatment, multiple myeloma will result in death with a median survival of 7 months. Multiple myeloma is associated with a 10 year survival of 3%. The presence of plasma cell leukemia or soft tissue plasmacytomas is associated with a particularly poor prognosis among patients with multiple myeloma.[3] According to a report published by National Cancer Institute there is a 43.25% chance of 5 year survival.[4]
Natural History
Complications
Complications that can develop as a result of multiple myeloma are divided into:[5]
- Local complications:
- Hematologic complications, usually results from the replacement of normal bone marrow by infiltrating tumor cells and inhibition of normal (hematopoiesis) by cytokines
- Normocytic and normochromic anemia
- Bleeding disorders
- Pancytopenia due to bone marrow failure
- Skeletal complications
- Pathologic fractures
- Spinal cord compression present as back pain, numbness, dysthesias suggestive, loss of bowel or bladder control.
- Systemic complications:
- Hypercalcemia
- Renal insufficiency, may develop both acutely and chronically.
- Neurologic complications
- Infections
Prognosis
- Overall mortality rates peaked in the mid-1990s and have fallen in recent years.[6]
- The average survival of multiple myeloma patients is approximately 3 years and approximately 43.5% of patients survive after 5 years.
- The International Staging System can help to predict survival, with a median survival of 62 months for stage 1 disease, 45 months for stage 2 disease, and 29 months for stage 3 disease.
- Cytogenetic analysis of multiple myeloma cells may be of prognostic value, with deletion of chromosome 13, non-hyperdiploidy and the balanced translocations t(4;14) and t(14;16) conferring a poorer prognosis. The 11q13 and 6p21 cytogenetic abnormalities are associated with a better prognosis.
- Prognostic markers such as these are always generated by retrospective analyses, and it is likely that new treatment developments will improve the outlook for those with traditionally 'poor-risk' disease.
