Effect of the presence of hepatitis B e antigen on prognosis after liver resection for hepatocellular carcinoma in patients with chronic hepatitis B.
We examineded the clinical effects of serum hepatitis B e antigen (HBeAg) positivity on clinicopathologic findings and prognosis after liver resection for hepatocellular carcinoma (HCC) in patients with chronic hepatitis B. A series of 56 patients who underwent curative resection were divided into two groups: 25 HBeAg-positive patients (group 1) and 31 HBeAg-negative patients (group 2). The mean age was significantly lower in group 1 than in group 2 (p = 0.0021), and the proportion of patients with symptoms was significantly higher in group 1 than in group 2 (p = 0.037). There were no significant differences in other clinical findings between the two groups, including laboratory test results, coexisting medical conditions, and operative methods. Although tumor size, degree of differentiation of the main tumor, and the prevalence of vascular invasion did not differ between the groups, the prevalence of intrahepatic metastasis and the proportion of patients with active hepatitis were significantly higher in group 1 than in group 2 (p = 0.009 and p = 0.043, respectively). Tumor-free and cumulative survival rates were significantly lower in group 1 than in group 2 (p = 0.022 and p = 0.0001, respectively). Multivariate analysis of various possible risk factors demonstrated serum HBeAg positivity to be an independent risk factor for recurrence [risk ratio (RR) 2.49; 95% confidence interval (CI) 1.12-5.49; p = 0.032] and an independent unfavorable factor for the survival time (RR 7.58; 95% CI 2.10-27.8; p = 0.0020). We concluded that the prognosis after liver resection for HCC is worse for HBeAg-positive patients than for HBeAg-negative patients.
