OBJECTIVE Surgery is the primary treatment for endometrial carcinoma. Methods of complementary treatment are still debated, with the potential association of external radiotherapy and/or brachytherapy before or after surgery. This study was aimed at evaluating local control and complications rates in a series of patients treated by hysterectomy followed by postoperative vaginal low-dose rate brachytherapy (BT) combined with pelvic irradiation in case of poor prognosis factors. METHODS From 1978 to 1993, 101 patients were treated at the Centre Alexis-Vautrin, France according to this scheme. Forty five had deep myometrial invasion, and thirteen cervical involvement. Fifty patients received pelvic irradiation (median dose 46 Gy) combined with BT (dose 14 Gy, median volume 127 cm3); 51 patients had BT alone (dose 60 Gy, median volume 71 cm3). RESULTS The 5-year overall survival rate was 83% and the local control rate 97% with a median follow-up of 7 years. Multivariate analysis showed two factors of bad prognosis, i.e., deep myometrial invasion and cervical involvement. Three severe complications occurred in two patients for whom the treated volume was larger than the theoretical target volume. Eleven patients developed metastases. CONCLUSIONS Results obtained from this series are comparable with those of previous studies, particularly in regard to pre-operative BT. The complication rate is also satisfactory and depends on the irradiation precision and the definition of the target volume.
