title: Chemo-resistant choriocarcinoma metastatic to colon cured by low-anterior resection.
abstract: The role of surgery in the treatment of patients with metastatic choriocarcinoma has diminished. We present a case of chemo-resistant metastatic choriocarcinoma salvaged by surgery. A 48-year-old patient presented with uterine perforation and severe intractable hemorrhage, and histological examination revealed a choriocarcinoma. After 6 years of disease-free state, recurrence occurred in the rectosigmoid colon. Seven cycles of EMACO chemotherapy was administered, and the human chorionic gonadotropin level was normalized. Three months after the chemotherapy, the rectosigmoid colon metastasis progressed. Low anterior resection with lymphadenectomy up to the level of the inferior mesenteric artery was conducted. After the operation, the human chorionic gonadotropin level decreased to within the normal range. There has been no evidence of disease for 13 months since the operation. Local resection of metastases seems to play a significant role in curing the disease in a small subset of patients.
