[Hepatic arterial infusion of low-dose cisplatin, 5-fluorouracil for hepatocellular carcinoma with tumor thrombi in the portal vein].

Hepatic arterial infusion of low-dose CDDP (10 mg/day), 5-FU (250 mg/day) was performed in 5 unresectable hepatocellular carcinoma (HCC) patients with tumor thrombi in the trunk and/or the first branch of the portal vein. Infusion chemotherapy was continued for five days, then discontinued for the subsequent two days. This procedure was performed repeatedly for at least three weeks. Decrease in the serum levels of the alpha-fetoprotein after the treatment was found in 3 of 4 patients. In one patient, the size of the primary tumor decreased 92%. In two of five patients, the tumor thrombi in the portal vein disappeared, or decreased in size. Side effects of the chemotherapy included liver functional disorder (Grade 3; 1 case), thrombocytopenia (Grade 3; 1 case, Grade 2; 1 case), and leukopenia (Grade 2; 1 case). The present protocol proved to be effective and applicable for patients with advanced HCC associated with severe cirrhosis.
