Abstract
The long-term outcome after curative resection of hepatocellular carcinoma (HCC) remains unsatisfactory because of the high incidence of recurrence. The present study was intended to assess the impact of hepatitis B virus (HBV) DNA level and nucleos(t)ide analog therapy on posthepatectomy recurrence of HBV-related HCC. Eligible studies were identified through a computerized literature search. The pooled relative risk ratio (RR) with 95 % confidence interval (CI) was calculated using Review Manager 5.1 Software. Twenty studies with a total of 8,204 participants were included for this meta-analysis. Pooled analysis showed that high viral load was significantly associated with risk of recurrence (RR: 1.85, 95 % CI: 1.41-2.42; P < 0.001), poorer disease-free survival (DFS) (RR: 1.96, 95 % CI: 1.62-2.38; P < 0.001), and poorer overall survival (OS) (RR: 1.47, 95 % CI: 1.22-1.77; P < 0.001) of HBV-related HCC after surgical resection. Nucleos(t)ide analog therapy significantly decreased the recurrence risk (RR: 0.69, 95 % CI: 0.59-0.80; P < 0.001) and improved both DFS (RR: 0.70, 95 % CI: 0.58-0.83; P < 0.001) and OS (RR: 0.46, 95 % CI: 0.32-0.68; P < 0.001). High DNA level is associated with posthepatectomy recurrence of HBV-related HCC. Nucleos(t)ide analog therapy improves the prognosis of HBV-related HCC after resection.
