OBJECTIVE: Evaluate the impact of clinicopathologic characteristics and adjuvant treatment on survival outcomes in early stage uterine carcinosarcoma patients. METHODS: We performed a retrospective cohort study of women with stage I or II uterine carcinosarcoma at our institution between March 1990 and June 2016. All pathology had been reviewed and confirmed by gynecologic pathologists. Data were extracted from the electronic medical record. Descriptive and comparative statistics were used to compare clinicopathologic characteristics. Univariable and multivariable analyses were performed for survival outcomes. RESULTS: 140 patients were identified. Median age was 67 years (range: 36-91). Median follow-up was 39.1 months (2.9-297.4). The majority of patients had stage IA (67%) versus stage IB (21%) or stage II (11%) disease. The majority of patients (63%) received adjuvant treatment: vaginal brachytherapy only (14%); whole pelvic radiation therapy only (16%); chemotherapy only (n = 13, 9%); combination chemotherapy and vaginal brachytherapy (15%); combination chemotherapy and whole pelvic radiation (9%). 52 patients (37%) received no adjuvant therapy. Median overall survival (OS) was 48.0 months (95% CI 32.7-80.9). On multivariable analysis for OS, advancing age (HR 1.05, 95% CI 1.03-1.08, p < 0.001), higher stage (stage IB: HR 1.64, 95% CI 0.91-2.95, p = 0.10; stage II: HR 3.04, 95% CI 1.51-6.13, p = 0.002), and the presence of a rhabdomyosarcoma component (HR 1.66, 95% CI 1.02-2.70, p = 0.04) were significantly associated with worse OS. CONCLUSIONS: Advancing age, stage, and the presence of a rhabdomyosarcoma component were all associated with worse OS in patients with early stage uterine carcinosarcoma. New treatment algorithms should incorporate factors aside from stage alone.
