['Little is known about the role of hepatitis B virus (HBV) factors in the long-term prognosis of hepatocellular carcinoma (HCC) after resection. The objective of the present study was to identify the changing patterns of HBV levels and its effect on outcome after resection.', 'This study recruited 188 patients with HBV-related HCC who underwent curative resection. Among the 188 patients, 115 were alive without recurrence at 12 months, and had serial measurements of viral levels.', 'The mean age was 53 years and the mean follow-up period was 48.5 months. With multivariate analysis, tumor size > 5 cm (P = 0.047), Child-Pugh class B (P = 0.017), vascular invasion (P = 0.028), and HBV DNA > 10(4) copies/mL at the time of resection (P = 0.003) were independently predictive of HCC recurrence for the entire population. For the 115 patients with serial measurements of viral levels, tumor size > 5 cm, HBV DNA > 10(4) copies/mL at resection, and the absence of sustained HBV DNA level < 10(4) copies/mL, the presence of cirrhosis, and elevated aminotransferase levels (> 40 IU/L) were marginally or significantly associated with HCC recurrence and overall survival. However, on multivariate analysis, sustained HBV DNA level < 10(4) copies/mL was the only factor for both low recurrence (P = 0.002; odds ratio [OR] 3.13; 95% confidence interval [CI] 1.55-6.35) and longer survival (P = 0.002; OR 3.76; 95% CI 1.61-8.78).'] Does sustained low hepatitis B viral load predict good outcome after curative resection in patients with hepatocellular carcinoma?
