BACKGROUND: Hepatocellular carcinoma (HCC) with tumor thrombosis of the main trunk of the portal vein (PVTT) has a poor prognosis. This study was designed to evaluate the efficacy of arterial infusion chemotherapy for advanced HCC of this type. METHODS: Nine patients with HCC were treated by arterial infusion of a chemotherapeutic agent via a subcutaneously implanted injection port. One course consisted of the daily administration of cisplatin (10 mg for 1 hour on Days 1-5) and the subsequent infusion of 5-fluorouracil (250 mg for 5 hours on Days 1-5). In principle, patients were to receive four serial courses of chemotherapy. RESULTS: The mean course of chemotherapy was 4.6 (range, 2.6-7.6) months. The serum total concentrations of alpha-fetoprotein and des-gamma-carboxyprothrombin were reduced after chemotherapy in most of the patients. Two patients showed complete response (CR) with disappearance of HCC and PVTT after treatment, and the other two showed partial response (PR) (response rate [CR + PR/All cases], 44.4%). The 3-year survival rate was 40%. The mean survival after the therapy was 14.9 (range, 4.1-48.9) months. The 50% survival was 9.2 months. Adverse reactions were tolerable nausea and loss of appetite. CONCLUSIONS: This chemotherapeutic regimen achieved favorable results and may be useful in treating patients with HCC with tumor thrombosis of the main trunk of the portal vein.
