Background: Endometrial adenocarcinoma is the most common gynecological cancer in the Western world and its incidence appears to be rising. However, population-based studies on endometrial cancer providing survival estimates by age, histology, and stage in Asia have been sparse. The aim of this study was to evaluate the clinicopathological data and survival for patients with endometrial adenocarcinoma treated at three institutions in Yazd, Iran. Materials and Methods: Medical and anatomicopathological records at the Department of Pathology and Radiotherapy of the Shahid Sadoughi University of Medical Sciences and Madar private hospital, between 2005 and 2012 were reviewed. All cases of endometrial adenocarcinoma were included. The Kaplan-Maier method was used for survival analysis and Cox proportional hazards model for multiple regression analysis. Results: The study included 84 patients. Stages I, II, III, and IV were identified in 65.4%, 21.5%, 11.9% and 1.2%, respectively. Disease-free survival rate was $73.9{pm}3.77$ months (95% confidence interval, 64.51-83.22 months) and relapse occurred in 12.3% of the patients. The overall survival rate was $78.2{pm}3.65$ months (95% confidence interval, 71.0-85.3 months). A multivariate analysis revealed that stage and grade were associated with overall survival. Conclusions: In this survival analysis of patients with endometrial cancer, we found that the prognosis of endometrial cancer was fair but strongly varied by stage and grade, and moderately varied by histology and age.
