OBJECTIVE: To examine the patterns of care and survival for African American and white women with high-grade endometrial cancer. METHODS: The linked Surveillance, Epidemiology, and End Results and Medicare databases were queried to identify patients diagnosed with grade 3 endometrioid endometrial adenocarcinoma, uterine carcinosarcoma, uterine clear cell carcinoma, and uterine serous carcinoma between 1992 and 2009. The effect of treatment modality on survival was analyzed using the Kaplan-Meier method. Factors predictive of outcome were compared using the Cox proportional hazards model. RESULTS: A total of 9,042 patients met study eligibility criteria. African Americans had definitive surgery (76.8% compared with 88.7%; P<.001) less frequently. There was no difference in the rate of adjuvant treatment between the groups. In the crude models for both all-cause mortality and cancer-specific mortality, African American women had an increased overall and disease-specific hazard of death compared with white women. The overall hazard ratio for African American women was 1.6 (95% confidence interval [CI] 1.5-1.7), and the disease-specific hazard ratio was 1.5 (95% CI 1.3-1.6). Over the entire study period, after adjusting for stage, age, period of diagnosis, registry region, urban compared with rural setting, marital status, treatment, surgery, socioeconomic status, and comorbidities, there was no association between race and lower disease-specific survival (hazard ratio 1.1, 95% CI 1-1.2; P=.06). CONCLUSION: African American women had lower cancer-specific and all-cause survival compared with white women. Controlling for treatment, sociodemographics, comorbidities, and histopathologic variables eliminated the difference between African American and white women in the disease-specific analysis.
