Abstract
The patient was a 76-year-old male, who was seen at an another hospital with a complaint of melena. He was diagnosed as Sigmoid colon cancer and hepatic metastases. We only performed sigmoidectomy because his performance status was not good, and hepatectomy seemed to be difficult. After operation, We started a FOLFOX4 regimen. After 8 courses of FOLFOX4, a reduction of hepatic metastases was observed, and it was difficult to continue the chemotherapy due to a side effect. Then we performed hepatectomy. In the histopathology, an adenoma was found in one area, but only necroses and calcification remained otherwise as a result of the chemotherapy. Hepatectomy after chemotherapy seemed to be a useful treatment for unresectable hepatic metastasis.
