Objective:
To compare postoperative radiotherapy and observation for survival and recurrence rates in stage IC endometrial carcinoma patients who underwent comprehensive surgical staging.
Study Design:
Fifty-seven stage IC endometrial cancer patients who underwent surgical staging were included in this study. Twenty cases (35%) received postoperative radiotherapy and 37 (65%) were observed without additional therapy. The two groups were compared for survival and recurrence rates.
Results:
Mean follow-up times for the radiotherapy and observation groups were 52.05 and 38.71 months, respectively. Five-year disease-free survival rates for the radiotherapy and observation groups were 91% and 63%, respectively, and 5-year overall survival rates for the radiotherapy and observation groups were 90.0% and 80.8%, respectively. Both the disease-free and overall survival rates were similar between the two groups (p > 0.05). One (5%) of the 20 patients in the radiotherapy group, and four (10.8%) of the 37 patients in the observation group had recurrences and there was no statistical difference for the recurrence rates (p > 0.05). Disease grade had no prognostic significance in terms of survival after surgical staging.
Conclusions:
Comprehensive surgical staging might minimize the unfavorable role of deep myometrial invasion and grade. After surgical staging, postoperative observation without radiotherapy may be an appropriate approach in stage IC, all grades, endometrial carcinoma.
