BACKGROUND/AIMS: Despite an adequate hepatic resection, theprognosis of the patients with hepatocellular carcinoma (HCC) that have macroscopic tumor thrombus in the portal vein has still been poor. The prognosis of those patients and was investigated the significance of postoperative adjuvant therapy was discussed in this study. METHODOLOGY: Twenty five patients who had Vp2 or more portal invasion were included in this study. Those patients were retrospectively divided into 2 groups: the systemic interferon alpha, 5-Fluorouracil (FU) and cisplatin group (n = 10, IFN+ chemo group); and the no adjuvant therapy group (n = 15, control group). RESULTS: The overall survival rate was significantly higher in the IFN+chemo group compared with the control group. There was no significant difference between the 2 groups in regard to the disease-free survival rate. However, a difference in the recurrence pattern was observed between the 2 groups. In the IFN+chemo group, 3 of 6 patients with a recurrence had a single tumor in the remnant liver. While in the control group, 10 of 11 recurrent patients had either distant metastasis or multiple recurrences in the residual liver. CONCLUSIONS: Our new adjuvant systemic therapy including interferon alpha, 5FU and cisplatin for advanced HCC with macroscopic portal invasion is promising.
