BACKGROUND Hepatocellular carcinoma(HCC)often presents as unresectable,necessitating effective treatment modalities.Combining transarterial chemoembolization(TACE)with immunotherapy and targeted therapy has shown promise,yet real-world evidence is needed.AIM To investigate effectiveness and safety of TACE with tislelizumab±targeted therapy for unresectable HCC in real-world setting.METHODS This retrospective study included patients with unresectable HCC receiving combined treatment of TACE and tislelizumab.The clinical outcomes included progression-free survival(PFS),overall survival(OS),objective response rate(ORR),and disease control rate(DCR).All patients were evaluated according to the mRECIST criteria.The adverse event(AE)was also assessed.RESULTS In this study of 56 patients with median follow-up of 10.9 months,7 had previous immunotherapy.Tislelizumab was administered before TACE in 21(37.50%)and after in 35(62.50%)patients,with 91.07%receiving concurrent targeted therapy.Median PFS was 14.0(95%CI:7.0-18.00)months,and OS was 28(95%CI:2.94-53.05)months.Patients with prior immunotherapy had shorter PFS(6 vs.18 months,P=0.006).Overall ORR and DCR were 82.14%and 87.50%.Grade≥3 treatment-related AEs included increased alanine aminotransferase(8.93%),aspartate aminotransferase(10.71%),and total bilirubin(3.57%).CONCLUSION The combination of TACE and tislelizumab,with or without targeted therapy,demonstrated promising efficacy and safety in unresectable HCC,especially in immunotherapy-naive patients,warranting further prospective validation studies. 展开更多
