Abstract
BackgroundThinking of the rarity and malignancy of gynecologic tract carcinosarcomas (GTCS), the aim of the study was to investigate the possible predictors of relapse-free survival (RFS) and overall survival (OS) for GTCS patients.MethodsWe performed a retrospective cohort study of women with GTCS at our hospital between January 2009 and December 2013. We used the Kaplan–Meier method to calculate RFS and OS, and Cox regression analysis to define the survival effects of risk factors.ResultsA total of 45 GTCS patients were included in the study. The median follow-up time was 46 months. Cox regression analysis showed that lymph node metastasis was significantly associated with worse RFS (HR: 3.145; 95%CI: 1.181–8.378; P=0.022) and OS (HR: 4.065; 95%CI: 1.57–10.524; P=0.004). Pelvic lymphadenectomy had a favorable RFS (HR: 0.213; 95%CI: 0.057–0.796; P= 0.021).ConclusionLymph node metastasis significantly affected the prognosis of uterine carcinosarcoma. Pelvic lymphadenectomy could reduce the relapse rate of GTCS patients.
