Retrospective cohort study of geographic variation of racial and ethnic differences in uterine cancer survival in the United States

Racial and ethnic disparities in uterine cancer survival are well-documented; however, limited data exist regarding the interplay of geography, diversity, and race and ethnicity in survival disparaties. In a retrospective cohort study using 17 SEER registries data on 162,500 patients with uterine cancer, disease-specific survival was better among Asian patients, worse among Black patients, and not different among Hispanic patients compared with White patients. Location-stratified analyses comparing Asian, Black, and Hispanic patients with White patients with uterine cancer showed disparate survival within less and more diverse US locations; however, associations varied by race and ethnicity. The authors conclude that these findings suggest that race- and ethnicity-based survival differences among patients with uterine cancer varied within the US, providing clues on the settings where future research should be targeted.
