Material and Method: The medical records of patients with surgical stage III endometrial carcinoma, and receiving adjuvant treatment between January 2003 and December 2012 were reviewed. DFS and OS were analyzed using the Kaplan-Meier method and Cox proportional hazards model.

Results: Of the 54 eligible patients, 61% underwent radiation, 19% chemotherapy, and 20% chemotherapy with radiation. The median DFS was 36.7 months. The 3-year DFS and OS was 51.9% (95% CI 36.3-74.1%) and 70.6% (95% CI 57.4-86.8%), respectively. There was no significant difference in DFS and OS among treatment groups. Cox regression analysis showed grade 2-3 tumors and menopause were associated with poor DFS and OS.

Conclusion: The DFS and OS in stage III endometrial carcinoma receiving postoperative adjuvant therapy were quite good and were not different among radiation therapy, chemotherapy, and combined treatment groups. The multi-center randomized prospective study was needed to determine the standard modality.
