Patterns of Failures and Clinical Outcome of Patients with Early-Stage, High-Risk, Node-Negative Endometrial Cancer Treated with Surgery Followed by Adjuvant Platinum-Based Chemotherapy and Vaginal Brachytherapy.

OBJECTIVE: To assess the clinical outcome of patients with high-risk early-stage endometrial cancer and negative pelvic nodes who received adjuvant platinum-based chemotherapy plus vaginal brachytherapy (VBT). METHODS: This investigation assessed 80 patients who underwent hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy for stage Ib-II, grade 2-3 endometrioid (n = 43) or stage Ia-II nonendometrioid (n = 37) endometrial cancer. RESULTS: Five-year local control rate, 5-year disease-free survival, and 5-year overall survival were 97, 87, and 97%, respectively, for endometrioid carcinoma, and 66, 50, and 72%, respectively, for nonendometrioid carcinoma. CONCLUSIONS: This retrospective study appears to show that adjuvant platinum-based chemotherapy plus VBT achieve very good results in endometrioid carcinoma. This combined treatment seems to be less effective in nonendometrioid carcinoma.
