Abstract
BACKGROUND: Thinking 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. METHODS: We 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. RESULTS: A 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). CONCLUSION: Lymph node metastasis significantly affected the prognosis of uterine carcinosarcoma. Pelvic lymphadenectomy could reduce the relapse rate of GTCS patients.
