Durie-Salmon staging system

First published in 1975, the Durie-Salmon staging system [2] is still in use, but has largely been superseded by the simpler ISS:

  • stage 1: all of
    • Hb > 10g/dL
    • normal calcium
    • Skeletal survey: normal or single plasmacytoma or osteoporosis
    • Serum paraprotein level < 5 g/dL if IgG, < 3 g/dL if IgA
    • Urinary light chain excretion < 4 g/24h
  • stage 2: fulfilling the criteria of neither 1 nor 3
  • stage 3: one or more of
    • Hb < 8.5g/dL
    • high calcium > 12mg/dL
    • Skeletal survey: 3 or more lytic bone lesions
    • Serum paraprotein >7g/dL if IgG, > 5 g/dL if IgA
    • Urinary light chain excretion > 12g/24h
Stage Hemoglobin level Calcium level Skeletal survey Serum paraprotein level Urinary light chain excretion
Stage 1
  • > 10g/dL
  • 8.5-10.2 mg/dL
  • Normal or single plasmacytoma or osteoporosis
  • < 5 g/dL if IgG or < 3 g/dL if IgA
  • < 4 g/24h
Stage 2
  • 8.5-10g/dL
  • 10.2-12 mg/dL
  • fulfilling the criteria of neither 1 nor 3
  • 5-7 g/dL if IgG or 3-5 g/dL if IgA
  • 4-12 g/24h
Stage 3
  • < 8.5g/dL
  • > 12mg/dL
  • 3 or more lytic bone lesions
  • >7g/dL if IgG or > 5 g/dL if IgA
  • > 12g/24h



The table below lists the genetic risk factors for multiple myeloma:

Genetic Risk Factor Description
Age The chance to develop multiple myeloma increases as patients get older, where only 1% of multiple myeloma cases are diagnosed in patients younger than 35 years.
Gender Males are more commonly affected with multiple myeloma than females. The male to female ratio is approximately 2 to 1
Lynch Syndrome AKA Hereditary Non-polyposis Colorectal Cancer (HNPCC) AD inheritance; caused by a defect in one of the mismatch repair genes, most commonly hMLH1, hMSH2, hMSH6, or PMS2; the mean age at initial cancer diagnosis is around 48 years[3]

The table below lists the risk factors for multiple myeloma:

Risk Factor Description
Age The chance to develop multiple myeloma increases as patients get older, where only 1% of multiple myeloma cases are diagnosed in patients younger than 35 years[4][5][6]
Race African American and Native Pacific Islanders descents are at increased risk of developing multiple myeloma[7][8][9]
Gender Males are more commonly affected with multiple myeloma than females. The male to female ratio is approximately 2 to 1[10][11]
Having other plasma cell diseases Studies have shown that patients with other plasma cell diseases such as monoclonal gammopathy of undetermined significance develop multiple myeloma later in their lives.[12][13]
Family history A familial predisposition to myeloma exists due to hyperphosphorylation of specific proteins that may contribute to a higher rates of multiple myeloma in certain groups.[14][15][16][17]
Obesity A study by the American Cancer Society found that being overweight increases a person's risk of developing multiple myeloma[18][19]
Workplace exposures Petroleum workers and farmers tend to have higher incidence of multiple myeloma relative to other occupations[20][21][22]
Radiation Areas with previous history of atoms bombs or nuclear accidents had higher risk of multiple myeloma due to increased rate of radiation exposure [23][24]
