PURPOSE: To compare the survival outcome between radical hysterectomy and simple hysterectomy with radiation therapy in patients with stage II endometrial cancer.
MATERIALS AND METHODS: This is a retrospective cohort study based on the SEER database from January 1, 1988 to December 31, 2015.
RESULTS: Of 577 patients were enrolled in the study, 117 patients received radical hysterectomy and 460 patients received simple hysterectomy combined with vaginal brachytherapy. All patients received external beam radiation therapy after the surgery. The median follow-up duration was 82.77 ± 1.44 months. No differences were found on the baseline information between two groups. Both the 5-year overall survival (62.31% vs. 78.48%, p < 0.001) and 5-year cause-specific survival (74.60 vs. 85.38%, p = 0.01) were shorter in radical hysterectomy than in simple hysterectomy combined with vaginal brachytherapy group. However, the positive outcomes were further validated in patients with high-risk endometrial cancer, not in patients with grade 1-2 low-risk endometrial cancer both on cause-specific survival and overall survival. In patients with grade 3 low-risk endometrial cancer, the tendency was only found with lower overall survival not cause-specific survival.
CONCLUSIONS: This study revealed that in patients' high-risk stage II endometrial cancer, radical hysterectomy was associated with shorter survival outcome than simple hysterectomy combined with vaginal brachytherapy.
