Abstract
Background
The role of nucleos(t)ide analogs (NAs) therapy in intermediate and advanced hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) remains unclear.
Aims
The aim was to evaluate the effect of NAs therapy on survival of intermediate- and advanced-stage HBV-related HCC patients initially treated with chemoembolization.
Methods
A total of 1016 Barcelona Clinic Liver Cancer (BCLC) stage B/C HBV-related HCC patients initially treated with chemoembolization were included. Propensity score matching (PSM) was performed to decrease heterogeneity between the antiviral and non-antiviral groups. Kaplan–Meier and Cox regression analysis were performed to evaluate the effects of NAs therapy on overall survival (OS).
Results
Antiviral group (n = 394) significantly prolonged OS compared with non-antiviral group (n = 622) (p = 0.003). NAs therapy (p < 0.001) along with tumor size (p = 0.002), tumor number (p = 0.001), gross vascular invasion (p < 0.001), metastasis (p < 0.001), α-fetoprotein (p < 0.001), Child–Pugh score (p = 0.008), aspartate aminotransferase (p < 0.001), and HBV DNA (p = 0.018) were identified as independent prognostic factors for OS. After PSM processing, deducting the influence of subsequent treatments for HCC, NAs therapy was still identified as an independent protective factor (p = 0.009) for OS in patients who survived ≥ 7 months, regardless of BCLC stage B or C HCC.
Conclusion
NAs therapy prolongs OS in intermediate- and advanced-stage HBV-related HCC patients initially treated with chemoembolization. After PSM processing, patients who survived ≥ 7 months still benefited from NAs therapy.
