CA-125 is a useful predictor of disease status in uterine carcinosarcoma

Objective: Uterine carcinosarcoma is a rare and aggressive tumor with poor outcomes. CA-125 is routinely used to track the disease course in ovarian cancer and has been suggested as a biomarker in other aggressive forms of uterine cancer. We sought to characterize CA-125 as a potential biomarker of disease status in uterine carcinosarcoma.
