Polypoid or non-polypoid? A novel dichotomous approach to uterine carcinosarcoma

Conclusions. Polypoid carcinosarcomas differ from their non-polypoid counterparts in key histological parameters such as the carcinoma to sarcoma ratio, myometrial and lymphatic vascular invasion, stage and type of carcinomatous component. Patients with polypoid tumors may have a better survival outcome than those with non-polypoid tumors.
