[Abstract]
Introduction
Most hepatocellular carcinomas (HCC) develop in a background of underlying liver disease including chronic hepatitis B. However, the effect of antiviral therapy on the long-term outcome of patients with hepatitis B virus (HBV)-related HCC treated with chemoembolization is unclear. This study aimed to evaluate the survival benefits of anti-HBV therapy after chemoembolization for patients with HBV-related HCC.
Methods
A total of 224 HCC patients who successfully underwent chemoembolization were identified, and their survival and other relevant clinical data were reviewed. Kaplan-Meier and Cox regression analyses were performed to validate possible effects of antiviral treatment on overall survival (OS).
Results
The median survival time (MST) was 15.9 (95% confidence interval [CI], 9.5–27.7) months in the antiviral group and 9.6 (95% CI, 7.8–13.7) months in the non-antiviral group (log-rank test, P=0.044). Cox multivariate analysis revealed that antiviral treatment was a prognostic factor for OS (P=0.008). Additionally, a further analysis was based on the stratification of the TNM tumor stages. In the subgroup of early stages, MST was significantly longer in the antiviral-treatment group than in the non-antiviral group (61.8 months [95% CI, 34.8 months to beyond the follow-up period] versus 26.2 [95% CI, 14.5–37.7] months, P=0.012). Multivariate analysis identified antiviral treatment as a prognostic factor for OS in the early-stage subgroup (P=0.006). However, in the subgroup of advanced stages, MST of the antiviral-treated group was comparable to that of the non-antiviral group (8.4 [95% CI, 5.2–13.5] months versus 7.4 [95% CI, 5.9–9.3] months, P=0.219). Multivariate analysis did not indicate that antiviral treatment was a significant prognostic factor in this subgroup.
Conclusion
Antiviral treatment is associated with prolonged OS time after chemoembolization for HCC, especially in patients with early-stage tumors.
