About

For patients with recurrent liver cancer after liver transplantation, the median survival time is low and the prognosis is often poor. On the one hand, it is necessary to take into account the weakened effect of postoperative anti-rejection drugs with the use of immune checkpoint inhibitors, and on the other hand, the therapeutic effect of recurrent tumors should be taken into account. Both HAIC (hepatic arterial infusion chemotherapy) and T+A（Bevacizumab+Atezolizumab) have inhibitory effects on tumor, and we consider combining them organically to explore one that not only has a good inhibitory effect on tumor, but also better reduces the risk and degree of rejection. Therefore, in order to determine the feasibility and effectiveness of hepatic arterial infusion chemotherapy combined with Atezolizumab and Bevacizumab in the second-line treatment of patients with recurrent liver cancer after liver transplantation

Hepatic arterial infusion chemotherapy + Atezolizumab and bevacizumab

Experimental group

Description:

Hepatic arterial infusion chemotherapy: percutaneous introduction of a standard hepatic arterial catheter through the femoral artery. FOLFOX was sequentially transfused by a fixed catheter. Drugs:FOLFOX regimen: oxaliplatin, calcium folinate, and 5-FU. Atezolizumab: About 3 to 7 days after HAIC treatment, when liver function is stable (TBILI\<2 times the upper limit of normal), Atezolizumab therapy can be started. The dosage was 1200mg and was given intravenously for at least 1 hour, once every 3 weeks. The longest course of treatment is 24 months. Bevacizumab: About 3 to 7 days after HAIC treatment, when liver function is stable (TBILI\<2 times the upper limit of normal), bevacizumab therapy can be started. The dosage was 15mg/kg and was given intravenously for no less than 1 hour, once every 3 weeks. The longest course of treatment is 24 months.
