Uterine and Ovarian Carcinosarcomas: Do They Behave Similarly?

OBJECTIVE: We aimed to compare the clinicopathologic characteristics, recurrence patterns, and survival of patients with ovarian carcinosarcomas (OCs) and uterine carcinosarcomas (UCs). METHODS: Patients who were diagnosed with UCs or OCs on the basis of final pathology reports and who underwent surgery between January 1993 and January 2015 were included in the study. Data of patients were obtained from Gynecological Oncology Clinic electronic database and patient files. RESULTS: The study included 101 and 21 patients who underwent surgery for UCs and OCs, respectively. Forty percent and 67% of patients who had UCs and OCs, respectively, experienced lymph node metastasis (P = 0.051). Median follow-up time was 12 months (range, 1-158 months) for patients with UCs and 24 months (range 1-154 months) for patients with OCs. Recurrence developed outside the abdomen in 58% of patients with UCs and in 10% of patients with OCs (P = 0.005). Median time to recurrence was 9 months (range 3-58 months) in patients with UCs, whereas it was 18 months (range 11-72 months) in patients with OCs (P = 0.002). Five-year disease-free survival was 34% and 19% for patients with UCs and OCs, respectively (P = 0.90). Five-year overall survival was 56% for patients with UCs and 54% for patients with OCs (P = 0.51). CONCLUSION: We found that UCs recurred earlier and extra-abdominally. Recurrence pattern should be kept in mind during the planning of adjuvant therapies for these patients.

Clinical outcomes of uterine carcinosarcoma: results of 94 patients.

OBJECTIVE: We aimed to determine the clinicopathologic features and identify prognostic factors of patients with uterine carcinosarcoma. MATERIALS AND METHODS: A total of 94 patients with uterine carcinosarcoma who were diagnosed between January 1993 and October 2013 were included. Staging surgery consisted of total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, peritoneal cytology, and omentectomy. Staging is undertaken according to the 2009 International Federation of Gynecology and Obstetrics staging system. Kaplan-Meier survival analysis was used to determine the effects of variables on disease-free survival (DFS) and overall survival (OS). RESULTS: Seventy-nine patients underwent staging surgery and none of them had residual tumor after surgery. Three-year DFS and 3-year OS were 42.7% and 59.2%, respectively. In the univariate analysis, stage, presence of para-aortic metastatic lymph nodes, uterine serosal spread, positive peritoneal cytology, and extrapelvic metastases were associated with 3-year DFS and stage, presence of para-aortic metastatic lymph nodes, uterine serosal spread, positive peritoneal cytology, adnexal involvement, and extrapelvic metastases were associated with 3-year OS. Seventy-four patients received adjuvant therapy. Adjuvant therapy did not reduce recurrence or improve survival. Any of the chemotherapy regimens was not superior to the others. In the multivariate analysis, only age was an independent prognostic factor for 3-year DFS and no parameter was statistically significant for 3-year OS. CONCLUSIONS: Age was an independent prognostic factor for 3-year DFS. Older age was associated with poor survival. Extrauterine spread was associated with survival. The aims of surgery should be both staging and providing tumoral debulking. Prospective randomized trials are needed to better define the necessity and modality of the administered adjuvant therapy.
