Abstract
We treated a man with unresectable hepatic metastases from sigmoid colon carcinoma who has since survived for more than 10 years. A sigmoidectomy with lymph node dissection was performed and a continuous hepatic arterial infusion of 5-fluorouracil (5-FU) with intermittent infusion of mitomycin C (MMC) was administered for about 3 months after this operation. The total doses of 5-FU and MMC were 16 g and 84 mg, respectively. Tegafur also was administered orally at a dose of 600 mg/day for about 8 months. The carcinoembryonic antigen (CEA) level (which had reached 4,409 ng/ml preoperatively) normalized 4 months after surgery, and still remains normal. Very few patients with unresectable hepatic metastases survive for 5 or more years. However, regional chemotherapy can be effective in some patients.
