Abstract

The benefits of entecavir (ETV) versus tenofovir disoproxil fumarate (TDF) in reducing the development of chronic hepatitis B (CHB)-related hepatocellular carcinoma remain controversial. Whether mortality rates differ between patients with CHB treated with ETV and those treated with TDF is unclear.A total of 2542 patients with CHB treated with either ETV or TDF were recruited from a multinational cohort. A 1:1 propensity score matching was performed to balance the differences in baseline characteristics between the two patient groups. We aimed to compare the all-cause, liver-related, and non-liver-related mortality between patients receiving ETV and those receiving TDF.The annual incidence of all-cause mortality in the entire cohort was 1.0/100 person-years (follow-up, 15 757.5 person-years). Patients who received TDF were younger and had a higher body mass index, platelet count, hepatitis B virus deoxyribonucleic acid levels, and proportion of hepatitis B e-antigen seropositivity than those who received ETV. The factors associated with all-cause mortality were fibrosis-4 index > 6.5 (hazard ratio [HR]/confidence interval [CI]: 3.13/2.15-4.54, P < 0.001), age per year increase (HR/CI: 1.05/1.04-1.07, P < 0.001), alanine aminotransferase level per U/L increase (HR/CI: 0.997/0.996-0.999, P = 0.003), and ?-glutamyl transferase level per U/L increase (HR/CI: 1.002/1.001-1.003, P < 0.001). No significant difference in all-cause mortality was observed between the ETV and TDF groups (log-rank test, P = 0.69). After propensity score matching, no significant differences in all-cause, liver-related, or non-liver-related mortality were observed between the two groups.Long-term outcomes of all-cause mortality and liver-related and non-liver-related mortality did not differ between patients treated with ETV and those receiving TDF.
