BACKGROUND. Patients with advanced hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) have a particularly grave prognosis. In the current study, an attempt was made to localize chemoradiation therapy (CCRT) followed by hepatic arterial infusion chemotherapy (HAIC) in patients with locally advanced HCC with PVT and good reserve liver function. The objective of the current study was to evaluate the therapeutic effect of localized CCRT followed by HAIC as a new treatment modality for these patients. METHODS. Between January 1998 and December 2003, 40 patients were recruited. Concurrent regional chemotherapy using an intra-arterial implanted port plus localized external beam radiotherapy was performed with a total of 45 gray (Gy) over 5 weeks with conventional fractionation and hepatic arterial infusion of 5-fluorouracil (5-FU), which was administered during the first and fifth weeks of radiotherapy. One month after localized CCRT, HAIC with 5-FU and cisplatin was administered every 4 weeks. RESULTS. One month after localized CCRT, an objective response was observed on the intention-to-treat analysis in 18 of 40 patients (45%). The actuarial 3-year overall survival rate was 24.1% and the median survival time was 13.1 months from the start of radiation treatment. Responders after localized CCRT demonstrated significantly better survival (P 5.033) than nonresponders. CONCLUSIONS. The substantial response rate as well as median survival time noted in the current study encourages the use of this new approach in patients with locally advanced HCC with PVT.
