We examine changes in population level incidence and survival of patients diagnosed with myelodysplastic syndrome (MDS) in the United States in 2001-2016. Data were extracted from the Surveillance, Epidemiology, and End Results (SEER)-18 database. Period analysis was used to calculate one-, two-, and five-year survival. The incidence peaked at 5.6 per 100,000 in 2010 then decreased to 3.9 by 2016, with a decrease in the diagnoses of refractory anemia (RA) and RA with ringed sideroblasts (RARS) and a relative increase in RA with excess blasts (RAEB). Overall, one-, two-, and five-year relative survival decreased over time, going from 74.3%, 60.9%, and 42.3%, respectively, in 2008-2010 to 70.9%, 55.9%, and 37.6%, respectively, in 2014-2016. When survival was examined by histology, patients with RA/RARS and RAEB had similar survival expectations in 2008-2010 versus 2014-2016 and a decrease was observed for 5q-MDS. Our results highlight the need for new treatment options in MDS.
