Abstract
ObjectiveTo determine the impact of adjuvant therapy and other factors associated with the recurrence and survival of patients with uterine carcinosarcoma (UCS). MethodsA total of 102 patients who underwhent surgery for UCS from 1998 to 2017 were included in the analysis. Data were analyzed using Kaplan–Meier methods and Cox proportional hazards regression. ResultsAt 240 months, the actuarial recurrence rate was 34.3%. Distant recurrence was the most common recurrence pattern. Patients with higher CA 125 levels, sarcoma dominance, cervical involvement, advanced stage, no lymphadenectomy, and residual tumour had a significiantly higher risk of recurrence. Five-year disease-free survival (DFS) and overall survival (OS) were 67% and 77%, respectively. FIGO stage was found to be an independent prognostic factor for DFS and OS. Sarcoma dominance was independently associated with decreased OS. ConclusionSarcoma dominance is associated with poor survival in UCS. Adjuvant treatment was not found to affect recurrence or survival. Given this finding, more effective postoperative strategies are needed.
