Clinicopathologic features of ovarian mixed mesodermal tumors and carcinosarcomas

Over a 27-year period there were 15 patients treated at the University of Michigan Medical center for carcinosarcomas or mixed mesodermal tumors of the ovary. Overall median survival was 11 months. Median survival was 4 months in patients with carcinosarcomas and 13 months in patients with mixed mesodermal tumors (P = 0.066). Patients with a chondrosarcomatous element had a significantly longer median survival than patients with mixed mesodermal tumors lacking cartilaginous differentiation (P = 0.031). The presence of a rhabdomyosarcomatous element did not affect survival. The size of the primary tumor, presence of ascites, FIGO stage, and degree of initial resection (optimal versus suboptimal) did not affect survival. There was no difference in survival between patients receiving postoperative chemotherapy and patients undergoing postoperative irradiation.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/28069/1/0000512.pd
