Purpose: This study was performed to determine the prognostic factors influencing relapse pattern, overall and disease-free survival in patients treated with postoperative radiotherapy for endometrial carcinoma.

Materials and Methods: The records of 54 patients with endometrial adenocarcinoma treated postoperative radiotherapy at Pusan National University Hospital between April 1992 and May 2003 were reviewed retrospectively. Median age of the patients was 55 (range 35¡­76). The distribution by surgical FIGO stages were 63.0% for 0Stage I, 14.8% for Stage II, 22.2% for Stage III. All patients received postoperative external radiotherapy up to 41.4¡­54 Gy (median: 50.4 Gy). Additional intravaginal brachytherapy was applied to 20 patients (37.0% of all). Median follow-up time was 35 months (5¡­115 months). Significant factors of this study: histologic grade, lymphovascular space invasion and myometrial invasion depth were scored (GLM score) and analyzed. Survival analysis was performed using Kaplan-Meier method. The log-rank test was used for univariate analysis and the Cox regression model for multivariate analysis.

Results: 5-year overall and disease-free survival rates were 87.7% and 87.1%, respectively. Prognostic factors related with overall and disease-free survival were histologic grade, lymphovascular space invasion and myometrial invasion according to the univariate analysis. According to the multivariate analysis, lymphovascular space invasion was associated with decreased disease-free survival. GLM score was a meaningful factor affecting overall and disease-free survival (p=0.0090, p=0.0073, respectively) and distant recurrence (p=0.0132), which was the sum of points of histologic grade, lymphovascular space invasion and myometrial invasion. Total failure rate was 11% with 6 patients. Relapse sites were 2 para-aortic lymph nodes, 2 lungs, a supraclavicular lymph node and a vagina.

Conclusion: The prognosis in patients with endometrial carcinoma treated by postoperative radiotherapy was closely related with surgical histopathology. If further explorations confirm the system of prognostic factors in endometrial carcinoma, it will help us to predict the progression pattern and to manage.
