Ovarian carcinosarcoma, also known as a malignant mixed mullerian tumor (MMMT) of the ovary, is a rare, aggressive cancer of the ovary with characteristics of two types of cancer: carcinoma and sarcoma. Because women with this cancer often have no symptoms, more than half of women are diagnosed at an advanced stage. When present, symptoms may include pain in the abdomen or pelvic area, bloating or swelling of the abdomen, quickly feeling full when eating, or other digestive problems. The cause of ovarian carcinosarcoma is not yet understood. Treatment usually consists of surgery to remove the tumor and chemotherapy. The chance of recovery and long-term survival (prognosis) is poor, with a reported 5-year survival rate of about 28%.
