Background/AimsPrevention of recurrence is the most important strategy to improve long-term survival after resection of hepatocellular carcinoma (HCC). This comparative study aimed to evaluate the outcome of adjuvant transarterial chemoembolization (TACE) after hepatectomy.MethodologyFrom February 1996 and September 2001, 721 consecutive patients (adjuvant TACE treatment vs. control group; 145 vs. 576) with R0 resection for HCC were analyzed. The prospective data was analyzed retrospectively.ResultsAfter a median follow-up of 75 months, 89 patients (61.4%) in the adjuvant TACE group and 355 patients (61.6%) in the control group had recurrent disease. There was no significant difference in the tumor recurrence rate between the 2 groups. There was significant difference in the tumor recurrence time between the 2 groups. The 1-, 3- and 5-year overall survival rates were 96.5%, 70.0% and 55.9%, respectively, for the adjuvant TACE group and 80.8%, 49.7% and 38.8%, respectively, for the control group. The 1-, 3- and 5-year disease-free survival rates were 79.9%, 54.9% and 48.4%, respectively, for the adjuvant TACE group and 60.2%, 39.8% and 31.5%, respectively, for the control group. The differences in the disease-free survival rates and the overall survival rates between the 2 groups were significant. In subgroup analysis, there was significant survival benefit in the adjuvant TACE group in the subgroup of patients with risk factors of recurrence - large tumor size, presence of satellite tumor nodules and narrow resection margin.ConclusionsAdjuvant TACE improved surgical outcome in those patients with risk factors of HCC recurrence.
