Enhanced prognosis of HCC patients undergoing radical treatments with tenofovir versus entecavir: A meta-analysis based on propensity score matching studies

The selection of postoperative antiviral therapy for hepatocellular carcinoma (HCC) patients with HBV infection undergoing radical treatments (HPHR) is a topic of ongoing debate and controversy. The primary aim of this study was to compare the prognostic impact of selecting entecavir (ETV) or tenofovir disoproxil fumarate (TDF) as antiviral therapy options in HPHR. All the studies included in this analysis were implemented propensity score matching (PSM) methodology. Meta-analysis was performed using R statistical software (version 4.3.0). The primary outcome measures, overall survival (OS) and recurrence-free survival (RFS), were quantified using hazard ratios (HR) and 95% confidence intervals (CI). This study analyzed 13 studies involving 6961 patients (2394 in the TDF group and 4567 in the ETV group). We conducted a meta-analysis of 8 studies that included a total of 5289 patients using the PSM analysis method. In comparison to the ETV group, the TDF group demonstrated significantly better RFS (HR = 0.81; 95% CI, 0.70-0.93; p = 0.0034) and OS (HR = 0.61; 95% CI, 0.42-0.88; p = 0.0085). Furthermore, the disparity between the two drugs was particularly evident in the prognosis of patients undergoing hepatectomy. Regional disparities were observed, with mainland China studies favoring RFS benefits and Taiwan or Korea studies favoring OS benefits. In conclusion, TDF has demonstrated significant superiority over ETV in terms of RFS and OS outcomes for HPHR. The findings hold significant implications for informing clinical decision-making and guiding the selection of postoperative antiviral therapy drugs in HCC patients.
