Аннотация
PURPOSE: This retrospective study was conducted to evaluate the effectiveness and safety of a new combination therapy of radiotherapy (RT), hepatic arterial infusion chemotherapy (HAIC), tyrosine kinase inhibitors (TKI) and immune checkpoint inhibitors (ICI) for hepatocellular carcinoma (HCC) patients involving portal vein tumor thrombus (PVTT).
METHODS: A total of 71 HCC patients with PVTT were retrospectively analyzed: 45 patients were treated by 'HAIC + TKI + ICI' therapy and 26 patients by the new combination therapy. The primary outcomes were overall survival (OS), progression-free survival (PFS), and cumulative survival rate.
RESULTS: The PFS in the 'New combination therapy' group was longer than that in the 'HAIC + TKI + ICI' group (HR 0.459, 95%CI 0.253-0.832; P = 0.008). Meanwhile, the OS in the 'New combination therapy' group was also longer than that in the 'HAIC + TKI + ICI' group (HR 0.420, 95%CI 0.198-0.894; P = 0.024). Compared with 'HAIC + TKI + ICI' group patients, the 'New combination therapy' group patients had higher 1-year PFS rate and 1-year OS rate (P = 0.029; P = 0.015). There was no significant difference in the incidence of adverse events between the two groups.
CONCLUSION: The new combination therapy was an effective and safe non-surgical treatment for HCC patients with PVTT and could be considered a preferred therapy option.
