The treatment of transarterial chemoembolization/hepatic arterial infusion chemotherapy combined with lenvatinib and PD-1 inhibitor is effective against hepatocellular carcinoma with portal vein tumor thrombus: A systematic review
Abstract
BackgroundLenvatinib combined with programmed cell death protein-1 inhibitor has achieved good survival results in the treatment of hepatocellular carcinoma with portal vein tumor thrombus. Transarterial chemoembolization (TACE) or hepatic arterial infusion chemotherapy (HAIC) has attracted attention because of its high response rate and favorable survival rate in patients with liver cancer and portal vein tumor thrombus. This study aimed to compare the efficacy and safety of Lenvatinib combined with programmed cell death protein-1 inhibitor plus transarterial chemoembolization or hepatic arterial infusion chemotherapy in patients with hepatocellular carcinoma with portal vein tumor thrombus.MethodWe searched PubMed, Embase and the Cochrane Library for studies. These included randomized controlled trials or clinical trials of Lenvatinib plus programmed cell death protein-1 inhibitor plus transarterial chemoembolization or hepatic arterial infusion chemotherapy (intervention group) versus Lenvatinib plus programmed cell death protein-1 inhibitor or Lenvatinib plus transarterial chemoembolization/hepatic arterial infusion chemotherapy or Lenvatinib alone (control group) in liver cancer with portal vein tumor thrombus The primary outcomes were overall survival and progression-free time, and the secondary outcomes were response rate and the rate of adverse events. According to the heterogeneity among different studies, Revman5.4 was used to conduct fixed effect or random effect model analysis.ResultsFive clinical trials were included, including 311 cases in the intervention group and 309 cases in the control group. In terms of efficacy, compared with the control group, the overall survival (HR=1.88, 95%CI: 1.57-2.25, P < 0.00001) and progression-free survival (HR=1.62, 95%CI: 1.41-1.86, P < 0.00001), better efficacy, and better disease response than the control group. In terms of safety, the risk of treatment-related adverse events in the intervention group was higher than that in the control group, and White Blood cell count decreased (RR=0.72, 95%CI: 0.38-1.37, P=0.32), Platelet count decreased (RR=0.99, 95%CI: 0.65-1.51, P=0.96) and Total bilirubin increased (RR=0.86, 95%CI: Increased) 0.88-1.28, P=0.46) were lower than those in the control group, and the rest were higher than those in the control group, and the differences in some results were statistically significant.ConclusionsTransarterial chemoembolization or hepatic arterial infusion chemotherapy combined with Lenvatinib plus programmed cell death protein-1 inhibitor can effectively delay the progression, prolong the survival period and improve the quality of life of liver cancer patients with portal vein tumor thrombus.
