Hepatic arterial infusion (HAI) chemotherapy for liver metastases of colorectal cancer using 5-FU.

Thirty-three patients with liver metastases of colorectal cancer were treated by intra-arterial 5-FU chemotherapy. The median survival time of all patients was 14 months. A partial remission could be observed in nine patients, and a further 15 patients had stable disease. Patients were treated on an outpatient basis and the toxicity of treatment was mild. We observed no case of sclerosing cholangitis or chemical hepatitis. Intra-arterial 5-FU chemotherapy provided treatment results similar to those reported for FUdR but with less hepatobiliary toxicity.
