A 73-year-old man had undergone right hemicolectomy for advanced colon cancer in May 2006, and he concurrently had multiple liver metastases. After the operation, the patient was given chemotherapy with FOLFIRI. A partial response was achieved for twelve months, and then the liver tumors enlarged. Second-line chemotherapy with FOLFOX was delivered. After several months the liver tumors further enlarged and a new pulmonary lesion appeared with an increased serum CEA level. Therefore, chemotherapy with S-1 (120 mg/day) was started, with 2 weeks' administration followed by a one-week drug-free period. Several months later, the liver tumors and tumor makers decreased. S-1 is expected to be an effective agent for the treatment of advanced colon cancer with liver metastases after FOLFIRI and FOLFOX.
