Uterine and Ovarian Carcinosarcomas: Do They Behave Similarly?

ABSTRACT

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.
