Tenofovir versus entecavir on the prognosis of hepatitis B virus-related hepatocellular carcinoma: a systematic review and meta-analysis.

BACKGROUND

Tenofovir (TDF) and entecavir (ETV) are first-line treatments for patients with chronic hepatitis B virus (HBV) infection. However, the effect of TDF versus ETV on the prognosis of HBV-related hepatocellular carcinoma (HCC) has not been fully clarified yet.

RESEARCH DESIGN AND METHODS

PubMed, Embase and Web of science were searched up to March, 2021. Meta-analyses were performed for overall survival (OS), disease-free survival (DFS) and recurrence-free survival (RFS) to assess the effect of TDF versus ETV on the prognosis of HBV-related HCC.

RESULTS

A total of 10 studies comprising 4706 Asian patients were included. The pooled results revealed that TDF was associated with better OS (adjusted HR = 0.50, 95% CI: 0.40-0.62; I = 36.0%,  = 0.167) and better RFS/DFS (adjusted HR = 0.70, 95% CI: 0.55-0.89, I = 71.9%,  = 0.002) than ETV in treatment of HBV-related HCC. Subgroup analysis revealed that OS benefit from TDF was generally consistent, except for patients who underwent non-surgical treatment for HCC. Subgroup analysis also indicated that TDF reduces the risk of late recurrence (HR = 0.41, 95% CI: 0.18-0.0.93; I = 63.0%,  = 0.067) rather than early recurrence (HR = 0.99, 95% CI: 0.64-1.52; I = 61.3%,  = 0.076).

CONCLUSIONS

Compared with ETV, TDF has the advantage of improving OS and reducing late recurrence of patients with HBV-related HCC patients who underwent resection.
