Summary Background Long‐term outcomes after hepatic resection for hepatocellular carcinoma are not satisfactory because of high recurrence rates. Aim To assess whether a single session of pre‐operative transarterial chemoembolization affects post‐operative outcome. Methods We analysed outcomes retrospectively in 334 consecutive patients who underwent hepatic resection for hepatocellular carcinoma, initially judged resectable. Ninety‐seven of these patients had each undergone a single session of pre‐operative transarterial chemoembolization (transarterial chemoembolization + hepatic resection group), whereas 237 had not (hepatic resection group). Results Most clinicopathological characteristics were similar in the two groups. The overall survival rate was significantly higher in the hepatic resection than in the transarterial chemoembolization + hepatic resection group ( P = 0.011), whereas their disease‐free survival rates were comparable ( P = 0.67). The overall and disease‐free survival rates of the transarterial chemoembolization + hepatic resection group with incomplete tumour necrosis were significantly lower than those of the hepatic resection group ( P < 0.001 and P = 0.006, respectively). Multivariate analysis showed that pre‐operative transarterial chemoembolization, serum alpha‐fetoprotein elevation (>1000 ng/mL), tumour size (>5 cm) and vascular invasion were independent risk factors for poor overall survival after hepatic resection. Conclusions A single session of pre‐operative transarterial chemoembolization for initially resectable hepatocellular carcinoma worsens overall survival rate. It may also increase the risk of tumour recurrence in patients who achieve incomplete tumour necrosis.
