ABSTRACT
UNLABELLED: We aimed to evaluate long-term treatment outcomes and toxicity profile of postoperative radiotherapy (PORT) in Saudi women with uterine cancers. METHODS AND MATERIALS: Medical records of patients with histopathologically proven uterine cancers were reviewed and identified those who received PORT (45-50.4 Gy in 25-28 fractions) followed by vaginal brachytherapy (15-20 Gy in 3 to 4 sessions) after total abdominal hystrectomy and bilateral salpingo-oophorectomy (TAHBSO) in our center between August 2007 and April 2012. Data regarding the safety profile, locoregional control (LRC) or distant metastases control (DMC) and overall survival (OS) rates were analyzed. RESULTS: Median follow-up period was 60 months (range, 12-70) for 89 patients. Predominant histological type was endometrial (59 patients), followed by carcinosarcoma (17 patients) and leiomyosarcoma (13 patients). Median age at time of diagnosis was 57.6, 56 and 51.1 years for endometrial, carcinosarcoma and leiomyosarcoma respectively. LRC rates were 80.9%, 87.1% and 100% for leiomyosarcoma, carcinosarcoma and endometrial carcinoma respectively (p 0.4). DMC rates were 69.3%, 45% and 16.3% for endometrial, leiomyosarcoma and carcinosarcoma respectively (p 0.0001). Five-year OS rates were 71.1%, 60% and 16.3% for endometrial, leiomyosarcoma and carcinosarcoma respectively (p 0.001). Coxproportional hazard ratio model showed body mass index, FIGO stage, lymphovascular invasion in endometrial carcinoma, tumor size in leiomyosarcoma and histology in carcinosarcoma important prognostic factors for LRC. Acute grade 3 and 4 proctitis/enteritis seen only in 4 patients (4.5%) and late toxicities were minimal. CONCLUSION: PORT in Saudi women with uterine cancers showed better LRC, DMC and OS rates with minimal toxicity.
