The International Staging System (ISS) -calculated from serum albumin and beta-2 microglobulin (β2m)- is an established prognostic marker in multiple myeloma (MM), which has also been suggested to account for survival among general senior population. Our objective was to examine long-term survival of older women free of MM according to baseline ISS. The study included 230 community-dwelling healthy older women without known MM from the EPIDOS cohort (mean ± SD, 80.4 ± 3.4 years). Serum albumin and β2m were measured at baseline, and used to calculate the ISS a posteriori.
