Staging is a cumulative evaluation of all of the diagnostic information garnered and is a useful tool for stratifying the severity of patients’ disease. Currently, two staging systems for multiple myeloma are in use: the Salmon-Durie system, which has been widely used since 1975; and the International Staging System, developed by the International Myeloma Working Group and introduced in 2005. [32, 33]  A revision of the International Staging System, published in 2015, added genetic information to the standard laboratory tests. [34]  See also Multiple Myeloma Staging.
