Overview

If left untreated, most of patients with multiple myeloma may progress to develop fatigue, bone pain, and pallor.[1] Common complications of multiple myeloma include anemia, renal failure, skeletal complications, and neurological complications.[2] The prognosis of multiple myeloma is good with treatment while without treatment multiple myeloma will result in death with a median survival of 7 months.[3][4] Multiple myeloma is associated with a 10 year survival rate of 3%. The presence of plasma cell leukemia or soft tissue plasmacytomas is associated with a particularly poor prognosis among patients with multiple myeloma.[5] According to a report published by the National Cancer Institute there is a 43.25% chance of 5 year survival.[6]

Natural History

  • Most patients with multiple myeloma are initially asymptomatic. If left untreated, most of the patients with multiple myeloma will gradually develop fatigue, bone pain, and pallor.[7]
  • In as many as 30-40% cases the diagnosis may be incidental and is often diagnosed on routine blood screening.
  • As the tumor grows larger people may notice one or more of the symptoms.[8]

Complications

Complications that can develop as a result of multiple myeloma are divided into:[9]

  • Local complications:
  • Hematologic complications, usually results from the replacement of normal bone marrow by infiltrating tumor cells and inhibition of normal (hematopoiesis) by cytokines
  • Skeletal complications
  • Systemic complications:
  • Infections

Prognosis

  • The prognosis of multiple myeloma is good with treatment. Without treatment, multiple myeloma will result in death with a median survival of 7 months.[10][11]
  • Overall the 5-year survival rate of multiple myeloma is around 46.6%.[12][13]
  • Overall mortality rates peaked in the mid-1990s and have decreased in recent years with the development of new therapeutic interventions.[14]
  • The average survival of multiple myeloma patients is approximately 3 years and approximately 43.5% of patients survive after 5 years.[15]
  • The table below lists common prognostic factors for multiple myeloma:
Prognostic Factor Description
Stage Advanced stages of multiple myeloma is associated with poor prognosis.[16]
Kidney function An elevated level of creatinine is associated with poor prognosis.[17]
Labelling index The labeling index indicates how fast the cancer cells are growing. A high plasma cell labeling index (PCLI) or proliferation (reproduction) rate is associated with poor prognosis.[18]
Age Older patients have worse prognosis than younger patients.[19]
Chromosome changes 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.[20][21]
Assocciated plasma cell disorder The presence of plasma cell leukemia or soft tissue plasmacytoma is associated with a particularly poor prognosis among patients with multiple myeloma.[22]
Performance status Performance status is ranked on a 0–4 scale. The lower the number, the healthier and more active the person is, and the better the prognosis. Performance status is important in multiple myeloma because people who are healthier can withstand more intensive treatment.[23]
Blood tests Abnormal blood tests play an important role in determining prognosis in people with multiple myeloma.[24]
Beta-2-microglobulin A higher level of beta-2-microglobulin is associated with poor prognosis.[25]
Albumin level A lower albumin level is associated with poor prognosis.[26]
Lactate dehydrogenase level A higher level of lactate dehydrogenase (LDH) is associated with poor prognosis.[27]
Response to treatment People whose cancer responds to treatment and goes into complete remission have a better prognosis than people whose cancer does not respond to the initial treatment.[28]
