Hepatocellular carcinoma (HCC) is closely associated with chronic hepatitis B or C virus (HBV, HCV) infection. Tumor recurrence frequently occurs after surgical resection and may adversely affect the outcome. This study aimed to investigate the effect of viral hepatitis in association with HCC recurrence after resection. A total of 248 patients [HBV in 165, HCV in 44, dual HBV+HCV in 15, and non-B non-C (NBNC) in 24] who underwent curative resection for HCC were included. The cumulative recurrence rate was compared according to the etiology of the underlying hepatitis and was stratified by tumor size and other clinicopathologic parameters. Altogether, 116 patients (47%) had a tumor recurrence within 17 +/- 11 months after resection. No significant difference in recurrence was noted among the four groups of patients (HBV, HCV, HBV+HCV, NBNC) ( p = 0.248). Persistent hepatitis was more common in the HCV group ( p < 0.001) after resection. Among the 157 patients with a small (= 5 cm) tumor, the recurrence rate was significantly higher in the HCV group than in the HBV, HBV+HCV, and NBNC groups ( p = 0.036). Cox multivariate analysis showed that HCV infection [relative risk (RR) 4.4, 95% confidence interval (CI) 1.3-14.8, p = 0.018] and vascular invasion (RR 3.2, 95% CI 1.2-8.9, p = 0.044) were independent predictors of tumor recurrence. Stratified analysis in other parameters did not show significant differences in terms of tumor recurrence among the four virologic groups ( p > 0.1 for all parameters). In conclusion, patients with small HCCs and concurrent HCV infection are at a high risk of tumor recurrence after resection.
