This study aimed to investigate the efficacy and safety of hepatic arterial interventional therapies (HAIT) combined with lenvatinib and programmed cell death-1 (PD-1) inhibitors for HCC patients with PVTT.Methods: In this retrospective study, HCC patients with PVTT treated with HAIT combined with lenvatinib and PD-1 inhibitors (H-L-P group) or lenvatinib plus PD-1 inhibitors (L-P group) between June 2020 and December 2023 were analyzed. Overall survival (OS), progression-free survival (PFS), and tumor response were evaluated to assess the efficacy, while treatment-related adverse events (TRAEs) were evaluated to assess the safety. Propensity score matching (PSM) was applied to balance the baseline differences.Results: In this study, 208 HCC patients with PVTT were enrolled, including 120 patients in H-L-P group and 88 patients in L-P group. After PSM, there were 74 patients per group, the H-L-P group showed significantly better median OS (19 months vs 14 months, p < 0.001) and median PFS (10 months vs 4 months, p < 0.001) than L-P group; higher objective response rate (ORR) (37.8% vs 16.2%, p < 0.001) and disease control rate (DCR) (78.4% vs 47.3%, p < 0.001) were observed in the H-L-P group. All TRAEs were controlled, and the three most prevalent TRAEs in the H-L-P group were elevated aspartate aminotransferase (AST), elevated alanine aminotransferase (ALT), and vomiting.Conclusion: Combining HAIT with lenvatinib and PD-1 inhibitors is a safe and promising treatment pattern for HCC patients with PVTT.Keywords: hepatocellular carcinoma, hepatic arterial interventional therapies, lenvatinib, programmed cell death protein-1 inhibitors, portal vein tumor thrombosis
