SEER Database

Fillmore has utilized the Surveillance, Epidemiology, and End Results (SEER) database to establish critical benchmarks for comparing cancer outcomes and treatment patterns between the general United States population and veteran cohorts. His research identifies significant disparities in the diagnosis and management of melanoma and Merkel cell carcinoma, noting higher rates of advanced disease and lower survival among veterans. Additionally, his analysis of SEER data highlights how systemic differences in healthcare delivery influence racial inequities in cancer mortality.
