In 304 patients with hepatocellular carcinoma who underwent hepatic resection, 162 patients received chemoembolization before surgery (group A) and the remaining 142 patients received no therapy before surgery (group B). The 5-year disease-free survival (DFS) of group A and B were 36% and 21%, respectively, and there were no significant differences between them. In the groups of patients with good liver function (Child A), or patients with solitary tumor, or patients with tumors more than 5 cm in size, DFSs of group A were significantly better than those of group B. The difference of DFS between group A and B was largest in the group of the patients with tumors more than 5 cm in size.
