Impact of age, race and decade of treatment on overall survival in a critical population analysis of 40,000 multiple myeloma patients

With the availability of novel agents, the overall survival (OS) in patients diagnosed with multiple myeloma (MM) has improved over the last decade. Data on 40,294 MM patients in the years from 1973 to 2003 were obtained from the Surveillance, Epidemiology, and End Results Program (SEER) of the US National Cancer Institute. Statistical analyses evaluating gender, race, age, and year of diagnosis were performed using univariate and multivariate Cox regression models for the OS endpoint. The mean patient age at diagnosis was 68.3 years. Mean survival was 30 months (median = 19 months). Asian/Pacific Islander race was associated with an improved OS, HR 0.90 (CI 0.86-0.95, P
