Background and Aims: We investigated the efficacy of intra‐arterial 5‐fluorouracil (5‐FU) and systemic interferon (IFN)‐α (5‐FU‐IFN) in the treatment of hepatocellular carcinoma (HCC) with portal vein tumor thrombosis in the first branch or trunk (Vp3/4) and extrahepatic metastases. Methods: We examined 17 HCC patients with Vp3/4 and extrahepatic metastases (meta group) and 31 HCC patients with Vp3/4 (non‐meta group). Baseline intrahepatic tumor factors and the hepatic reserve were similar between groups. The extrahepatic metastases of the meta group were not considered prognostic factors. Following the administration of 5‐FU/IFN to all patients, we compared the survival rates, response, time to progression (TTP), and safety between groups. Results: For intrahepatic HCC, complete response, partial response, stable disease, progressive disease, and drop out were observed in no (0%), one (6%), seven (41%), nine (53%), and no (0%) patients of the meta group, and in five (16%), seven (23%), 13 (42%), five (16%) and one (3%) patient of the non‐meta group, respectively. The response rate was significantly lower in the meta group (6% vs 39%, P = 0.018). The median TTP of intrahepatic HCC and the median survival time were significantly shorter in the meta group than in the non‐meta group (1.6 vs 6.3 months, P = 0.0001, and 3.9 months vs 10.5 months, P < 0.0001, respectively). The multivariate analysis showed that the absence of extrahepatic metastases was a significant and independent determinant of both TTP of intrahepatic HCC ( P < 0.001) and overall survival ( P < 0.001). No patient died of extrahepatic HCC‐related disease. Conclusions: The efficacy of 5‐FU/IFN for advanced HCC with Vp3/4 and extrahepatic metastases was markedly limited.
