The objective of this retrospective study was to evaluate Stage IIIA endometrioid type endometrial carcinomas (ECCs) and to analyze clinical and pathological determinants of prognosis in three tertiary hospitals between January 2007 and January 2017. Forty-seven patients with a median age of 61 (range: 31 to 76) years were diagnosed with Stage IIIA disease. Median follow-up was 45 (range: 6 to 116) months. The five-year disease-free survival (DFS) rate was 57.2%, and the overall survival (OS) rate was 59.7%. In the univariate analysis, age and grade of the disease (1-2 versus 3) disease were found to be significant factors for DFS. Univariate analysis also revealed the presence of cervical stromal involvement and grade of the disease were associated with decreased OS. In the multivariate analysis, however, only patients with an advanced histological grade had a reduced risk for OS (hazard ratio [HR] 2.9; 95% confidence interval [CI] 1.020-8.615; p= 0.040). In conclusion, histological grade seems to be an independent prognostic factor for OS in patients with Stage IIIA ECCs.
