Tenofovir versus Entecavir on Outcomes of Hepatitis B Virus-Related Hepatocellular Carcinoma After FOLFOX-Hepatic Arterial Infusion Chemotherapy

PURPOSE: The efficacy of entecavir (ETV) versus tenofovir (TDF) on the prognosis of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients who underwent FOLFOX-hepatic arterial infusion chemotherapy (HAIC) remains unclear. In this study, we compared the outcomes between ETV and TDF in HBV-related advanced HCC patients who underwent FOLFOX-HAIC. METHODS: A total of 683 patients diagnosed with HBV-related HCC who underwent FOLFOX-HAIC and received TDF or ETV between January 2016 and December 2021 were included. Overall survival (OS), progression-free survival (PFS), HBV reactivation, and liver function of patients were compared between the ETV and TDF groups by propensity score matching (PSM). RESULTS: In the PSM cohort, for all patients and patients with ≥ 4 cycles of FOLFOX-HAIC, the median OS in the ETV group (15.2 months, 95% CI: 13.0–17.4 months; 16.6 months, 95% CI: 14.8–18.5 months; respectively) was shorter than that in the TDF group (23.0 months, 95% CI: 10.3–35.6 months; 27.3 months, 95% CI: 16.5-NA months; p=0.024, p=0.028; respectively). The median PFS in the ETV group (8.7 months, 95% CI: 7.9–9.5 months; 8.9 months, 95% CI: 8.0–9.8 months; respectively) was also shorter than that in the TDF group (11.8 months, 95% CI: 8.0–15.6 months; 12.7 months, 95% CI: 10.8–14.6 months; p=0.036, p=0.025; respectively). The rate of HBV reactivation in the ETV group was higher than that in the TDF group (12.3% vs 6.3%, p=0.040; 16.5% vs 6.2%, p=0.037, respectively). For liver function, the rate of ALBI grade that remained stable or improved in the ETV group was lower than that in the TDF group (44.6% vs 57.6%, p=0.006; 37.2% vs 53.8%, p=0.019, respectively). CONCLUSION: Compared with ETV, TDF was associated with a better prognosis, lower proportion of HBV reactivation, and better preservation of liver function in advanced HBV-HCC patients who underwent FOLFOX-HAIC, especially those who received ≥ 4 cycles.
