Racial and Ethnic Differences in Hysterectomy-Corrected Uterine Corpus Cancer Mortality by Stage and Histologic Subtype

The findings of this cohort study suggest a significant increase of nonendometrioid uterine carcinoma mortality rates, aligning with recent incidence trends. The factors associated with these trends are not well understood and require more investigation of possible mechanisms. Despite stable incidence rates, endometrioid cancer mortality rates have not decreased over the past decade at the population level, suggesting limited progress in treatment for these cancers. The substantial disparities in uterine corpus cancer mortality rates among non-Hispanic Black women cannot be fully explained by subtype distribution and stage at diagnosis.
