OBJECTIVE: The purpose of this study was to determine factors responsible for the increasing number of deaths from corpus cancer over three time periods. STUDY DESIGN: Data were collected from the Surveillance, Epidemiology and End Results database from 1988-2001. Kaplan-Meier and Cox proportional hazards regression analyses were performed. RESULTS: Of 48,510 women with corpus cancer, there was an increase in the proportion of patients dying from advanced cancers (52.1% to 56.0% to 68.8%; P < .001), grade 3 disease (47.5% to 53.3% to 60.6%; P < .001), serous tumors (14.3% to 18.4% to 16.6%; P < .001), and sarcomas (19.1% to 20.4% to 27.2%; P < .001) over time. On multivariate analysis, older age, African American race, lack of primary staging procedures, advanced-stage, high-grade, and non-endometrioid histology were independent prognostic factors for worse survival. CONCLUSION: Our data suggest that the increase in mortality in women with corpus cancer over the last 14 years may be related to an increased rate of advanced-stage cancers and high-risk histologies.
