Twenty-four hour intra-arterial infusion of 5-fluorouracil, cisplatin, and leucovorin is more effective than 6-hour infusion for advanced hepatocellular carcinoma

Abstract

To evaluate the time dependence of intra-arterial 5-fluorouracil (5-FU) therapy for advanced hepatocellular carcinoma (aHCC). Thirty-seven adult Japanese patients who had aHCC and liver cirrhosis were treated with combined intra-arterial 5-FU, cisplatin (CDDP), and leucovorin (LV). The Japan Integrated Staging score (JIS score) of each patient was 3 or more. The patients were divided into two groups, after which the 15 patients in group S were treated with 6-h infusion chemotherapy (LV at 12 mg/h, CDDP at 10 mg/h, and 5-FU at 250 mg/m2 per 4 h) and the 22 patients in group L were treated with 24-h infusion chemotherapy (LV at 12 mg/h, CDDP at 10 mg/h, and 5-FU at 250 mg/ m2 per 22 h). Continuous infusion chemotherapy was performed via the proper hepatic artery every 5 d for 4 wk using an implanted drug reservoir. The percentages of patients with a partial response after 4 wk of chemotherapy were 6.7% in group S and 31.8% in group L. The survival of group L was significantly better than that of group S, with the median survival time being 496 d in group L and 226 d in group S (P < 0.05). Continuous 24-h intra-arterial infusion is more effective for aHCC and can markedly prolong survival time as compared to 6-h infusion.
