Carcinosarcoma of the uterine body is a rare mixed tumor composed of both carcinoma and sarcoma. The 5-year survival rate for this cancer is 33-39%. We present a case study of a woman treated with multidisciplinary therapy who survived carcinosarcoma of the uterine body with liver metastasis for over ten years. After she was diagnosed with carcinosarcoma of the uterine body at the age of 61 years, a hysterectomy was performed. Seven years later, she was diagnosed with cecal carcinoma, and ileocecal resection and tumorectomy were performed. Pathological findings revealed recurrence of the carcinosarcoma with cecal adenocarcinoma. After an additional 6 months, multiple liver metastases were also detected on abdominal enhanced computed tomography. We performed a partial hepatectomy. The patient survived for over ten years from the first operation. Therefore, a relatively long survival time can be expected for carcinosarcoma of the uterine body when treated with multidisciplinary therapy including surgery.
