Long-Term Follow-Up and Overall Survival in NRG258, a Randomized Phase III Trial of Chemoradiation Versus Chemotherapy for Locally Advanced Endometrial Carcinoma

This randomized phase III trial aimed to determine whether treatment with cisplatin and volume-directed radiation followed by carboplatin and paclitaxel for four cycles (chemoradiotherapy [C-RT]) increased recurrence-free survival (RFS) and overall survival (OS) when compared with carboplatin and paclitaxel for six cycles (chemotherapy [CT]) in locally advanced endometrial cancer (UC). Previously reported results showed that C-RT did not improve RFS compared with CT. Here we report the final OS analysis. Patients with International Federation of Gynecology and Obstetrics (FIGO) 2009 stage III-IVA UC or stage I/II serous or clear cell UC and positive cytology were enrolled. The primary objective was RFS. Secondary objectives were OS, toxicity, and quality of life. Cumulative probabilities of OS were estimated using the Kaplan-Meier method. Subgroup analyses of treatment effect for FIGO stage, age, race, gross residual disease, histology, lymph-vascular space invasion, and body mass index were performed. In total, 813 patients were randomly assigned (407 C-RT and 406 CT). The median follow-up was 112 months. Median OS was not achieved in either arm. The stratified hazard ratio for death comparing C-RT versus CT was 1.05 (95% CI, 0.82 to 1.34, log-rank two-sided P value = .72). None of the factors analyzed predicted OS benefit from C-RT. Although C-RT reduced the rate of local recurrence compared with CT, it did not increase OS or RFS in stage III/IVA UC.

Radiation Therapy With or Without Cisplatin for Local Recurrences of Endometrial Cancer: Results From an NRG Oncology/GOG Prospective Randomized Multicenter Clinical Trial

PURPOSE Pelvic recurrence is a frequent pattern of relapse for women with endometrial cancer. A randomized trial compared progression-free survival (PFS) after treatment with radiation therapy alone as compared with concurrent chemotherapy. MATERIALS AND METHODS Between February 2008 and August 2020, 165 patients were randomly assigned 1:1 to receive either radiation treatment alone or a combination of chemotherapy and radiation treatment. The primary objective of this study was to determine whether chemoradiation therapy was more effective than radiation therapy alone at improving PFS. RESULTS The majority of patients had low-grade (1 or 2) endometrioid histology (82%) and recurrences confined to the vagina (86%). External beam with either the three-dimensional or intensity modulated radiation treatment technique was followed by a boost delivered with brachytherapy or external beam. Patients randomly assigned to receive chemotherapy were treated with once weekly cisplatin (40 mg/m2). Rates of acute toxicity were higher in patients treated with chemoradiation as compared with radiation treatment alone. Median PFS was longer for patients treated with radiation therapy alone as compared with chemotherapy and radiation (median PFS was not reached for RT v 73 months for chemoradiation, hazard ratio of 1.25 (95% CI, 0.75 to 2.07). At 3 years, 73% of patients treated definitively with radiation and 62% of patients treated with chemoradiation were alive and free of disease progression. CONCLUSION Excellent outcomes can be achieved for women with localized recurrences of endometrial cancer when treated with radiation therapy. The addition of chemotherapy does not improve PFS for patients treated with definitive radiation therapy for recurrent endometrial cancer and increases acute toxicity. Patients with low-grade and vaginal recurrences who constituted the majority of those enrolled are best treated with radiation therapy alone.
