Abstract
Background
Recent studies have shown that high hepatitis B virus (HBV) load is associated with increased risk of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). The aim of our study was to investigate the predictive role of HBV DNA and hepatitis B surface antigen (HBsAg) levels in early and late recurrence of HCC after curative resection in patients with HBV-related HCC.
Methods
From January 2008 to December 2010, a total of 248 patients underwent curative resection for HBV-related early-stage HCC (solitary tumor; < 5 cm in diameter or multinodular tumor; number of tumors ≤3 and diameter < 3 cm). We analyzed the predictive factors including HBV DNA and HBsAg levels for early recurrence (within 2 years) and late recurrence (after 2 years) of HCC after curative resection.
Results
The median follow-up duration was 33.3 months. Cumulative recurrence rates after resection at 1, 3, and 5 years were 16.6, 34.0, and 46.7 %, respectively. The multivariate analysis showed that risk factors for early recurrence were the presence of microvascular invasion (hazard ratio [HR] 3.86; p < 0.001), preoperative HBV DNA levels ≥ 20,000 IU/mL (HR 2.77; p < 0.001), and des-γ-carboxy prothrombin level ≥ 40 mAU/mL (HR 1.76; p = 0.045). Although, the risk factors for late recurrence by multivariate analysis were preoperative HBsAg levels ≥ 4,000 IU/mL (HR 2.80; p = 0.023) and age at resection ≥ 50 years (HR 3.22; p = 0.032).
Conclusion
The HBV DNA levels were associated with early recurrence, whereas HBsAg levels were associated with late recurrence after curative resection in HBV-related HCC.
