Abstract: Prior improvements in multiple myeloma (MM) survival were not fully observed in racial and ethnic minorities and older individuals. We hypothesized that improvements in MM management in recent years have reduced these disparities. We used the Surveillance, Epidemiology, and End Results registries to calculate the incidence and relative survival rates (RSRs) of MM in the United States for patients diagnosed from 1993 to 1997 (prethalidomide), 1998 to 2002 (introduction of thalidomide), 2003 to 2007 (bortezomib and lenalidomide), and 2008 to 2012 (upfront bortezomib and lenalidomide, early availability of carfilzomib and pomalidomide). MM incidence increased significantly among non-Hispanic whites (NHWs) and non-Hispanic black (NHB) men, but not among NHB women and Hispanics. Improvement in 5-year RSRs (1993-1997 vs 2008-2012) was seen among patients of all age and race/ethnicity groups. Ten-year RSRs (1993-1997 vs 2003-2007) improved for patients
