Clinical outcomes including overall survival (OS), progression-free survival (PFS), tumor response and adverse events (AEs) were compared between the two groups. The risk factors affecting OS and PFS were also analyzed.Results: The median OS and PFS of the TACE-Len-T group were significantly longer than those of the TACE-Len group (Median OS: not reached vs 13.8 months, P 3, and cTACE were independent risk factors for OS, whereas TACE-Len treatment was the only independent risk factor for PFS. The frequency and severity of AEs in the TACE-Len-T group were comparable to those in the TACE-Len group (any grade: 92.6% vs 91.2%, P=0.753; grade 3 or 4: 33.8% vs 32.3%, P=0.855).Conclusion: TACE-Len-T treatment significantly improved OS, PFS, ORR, and DCR over TACE-Len treatment, with a manageable safety profile in uHCC.Keywords: unresectable hepatocellular carcinoma, transarterial chemoembolization, lenvatinib, tislelizumab, immunotherapy
