Overview
International Staging System for multiple myeloma, based on β2-microglobulin (β2M) levels and serum albumin levels, was published by International Myeloma Working Group in 2003 and is the most widely used staging system. It is used for both guiding treatment as well as predicting prognosis.
Staging
- International Staging System
According to the International Staging System (ISS), there are three stages of multiple myeloma based on both β2-microglobulin and Albumin levels.[1][2]:

- Durie-Salmon staging system
First published in 1975, the Durie-Salmon staging system [3] is still in use, but has largely been superseded by the simpler ISS: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
Stages 1, 2 and 3 of the Durie-Salmon staging system can be divided into A or B depending on serum creatinine:
- A: serum creatinine < 2mg/dL (< 177 umol/L)
- B: serum creatinine > 2mg/dL (> 177 umol/L)
