We have previously shown that continuous intra-arterial combination chemotherapy (IACC) might be more effective for advanced hepatocellular carcinoma (aHCC) in patients with HCV-related liver cirrhosis (C-LC) or alcoholic liver cirrhosis (A-LC) than in patients with HBV-related LC (B-LC). However, it is still unknown whether IACC actually improves the prognosis of aHCC patients with liver cirrhosis (LC), because it is difficult to perform a randomized controlled trial for patients with a poor prognosis. The aim of this study was to retrospectively assess the influence of IACC on the prognosis of aHCC.
