Abstract [en]

Aim: The aim of the present study was to evaluate a consecutive series of ovarian carcinosarcomas with regard to prognosis, treatment and prognostic factors. Patients and Methods: A consecutive series of 81 ovarian carcinosarcomas from two well-defined geographic regions were studied with regard to survival, type of primary and adjuvant therapy and prognostic factors. All patients but one underwent primary surgery and some patients also received adjuvant chemotherapy (platinum-based) alone or in combination with radiotherapy. Univariate and multivariate Cox proportional regression analysis was used. Survival was analyzed by the Kaplan-Meier technique and differences were assessed by the log-rank test. Results: The mean age of the patients was 73 years. Fifty-one patients received adjuvant chemotherapy and nine patients pelvic irradiation. The 5-year overall survival rate was 10%. Adjuvant therapy (any type) and six completed cycles of chemotherapy were highly significant factors with regard to improved overall survival rate. The only significant tumor-associated prognostic factor was the International Federation of Gynecology and Obstetrics (FIGO) grade of the tumor. FIGO stage, site of metastatic spread, tumor size, histology, DNA ploidy, and tumor necrosis were nonsignificant factors. Therapy was rather well-tolerated and 29 patients (57%) completed at least six cycles of adjuvant chemotherapy. Conclusion: Adjuvant and completed chemotherapy according to the treatment plan were the most important prognostic factors. FIGO grade (grade 3 vs. 1-2) of the epithelial component of the tumor was also a significant prognostic factor in multivariate Cox analysis.
