Hepatic artery infusion of 5-FUDR after prior systemic 5-fluorouracil

Abstract

Twenty-one patients with disseminated colon carcinoma and clinically significant liver metastases were treated with 5-FUDR via hepatic artery infusion (HAI). All patients had previously received systemic chemotherapy consisting of either 5-fluorouracil aone or in combination with other agents. At the time of the initiation of the HAI, clinical disease in all patients was progressing. A PR of hepatic metastases was noted in eight patients (35%) with a median and mean duration of response of 4.5 and 5.0 months respectively. The median and mean survival from the start of HAI for responders was 8.0 and 9.0 months and for nonresponders was 1.0 and 1.6 months respectively. It appears that a significant response rate can be achieved with HAI of 5-FUDR in spite of previous exposure to fluorinated pyrimidines.
