PURPOSE: This study aimed to examine trends in the incidence and mortality rates of endometrial cancer (EC) across ethnic groups in Brazil and to analyze the demographic and clinicopathological characteristics associated with these trends. METHODS: The incidence of EC was analyzed from 2010 to 2015 using data from Brazilian Population-Based Cancer Registries (PBCRs), including crude rates and annual percentage changes (APCs). Clinical and sociodemographic information from 2000 to 2019 was gathered from Hospital-Based Cancer Registries. Mortality data between 2000 and 2021 were obtained from the National Mortality Information System, allowing for comparisons between White women and Black women. RESULTS: From 2010 to 2015, a total of 32,831 new cases of EC were reported across 13 PBCRs, with Black patients accounting for 35.7% of these cases. The median age at diagnosis was 63 years, with Black women diagnosed at a younger age than White women. Black patients experienced a significant increase in incidence rate (APC +6.7% CONCLUSION: Racial disparities in EC incidence and mortality in Brazil may be closely linked to unfavorable sociodemographic factors faced by Black women. Targeted public health initiatives are critical for improving early detection and access to equitable care for Black women.
