Lower incidence of hepatocellular carcinoma with tenofovir alafenamide in chronic hepatitis B: Evidence from a large-scale cohort

초록

Background & Aims: Tenofovir alafenamide (TAF) lacks extensive research regarding its impact on hepatocellular carcinoma (HCC). This study evaluated and compared the effects of TAF, tenofovir disoproxil fumarate (TDF), and entecavir (ETV) on HCC incidence using nationwide claim data. Methods: In total, 75,816 patients with treatment-na & iuml;ve HBV were included in the study and divided into TAF (n = 25,680), TDF (n = 26,954), and ETV (n = 23,182) groups after exclusions. Propensity score matching (1:1:1) resulted in 17,537 patients per group. HCC incidence rates were compared among the groups. Results: Before matching, the incidence of HCC was significantly lower in the TAF group compared with the TDF and ETV groups (11.47 vs. 15.04 and 14.24 per 1,000 person-years). The incidence rate ratio (IRR) for TDF was 1.31 (1.19-1.44) and for ETV was 1.24 (1.12-1.37). Before matching, the TAF group had a significantly lower HCC compared with TDF and ETV in both patients with and without cirrhosis. After matching, the TAF group had a lower HCC incidence compared with the TDF group (12.38 vs. 15.39, IRR 1.24, p <0.001) but not with ETV group (IRR 1.08, p = 0.219). In patients with cirrhosis, TAF had lower HCC incidence compared with TDF and ETV (30.25 vs. 39.56 and 38.51, respectively). In patients without cirrhosis, the TAF group had a lower HCC incidence compared with the TDF group (IRR 1.19, p = 0.030) but not the ETV group (IRR 0.85, p = 0.066). Cox regression analysis showed that the TAF group had a significantly lower HCC incidence compared with the TDF (hazard ratio 1.335, p <0.001) and ETV groups (hazard ratio 1.162, p = 0.011), after adjusting for age, gender, and cirrhosis status. Conclusions: The TAF group consistently demonstrated a lower incidence of HCC compared with the TDF and ETV groups, especially in patients with cirrhosis. (c) 2024 The Author(s).
