Real-world study of hepatic artery infusion chemotherapy combined with anti-PD-1 immunotherapy and tyrosine kinase inhibitors for advanced hepatocellular carcinoma.

Lay abstract Some tyrosine kinase inhibitors (TKIs) that inhibit tumor vessel growth, such as sorafenib and lenvatinib, have been recommended as first-line treatment for advanced hepatocellular carcinoma (HCC). In hepatic artery infusion chemotherapy, chemotherapeutic drugs can be delivered via a microcatheter to the tumor-supplying artery to increase the local drug concentration, leading to higher local disease control rates and less toxicity than systemic chemotherapy. The combination of anti-PD-1 immunotherapy plus TKIs was shown in a previous study to be a safe and effective treatment for advanced HCC. This study explored the safety and effectiveness of hepatic artery infusion chemotherapy, TKIs and an anti-PD-1 antibody for the treatment of advanced HCC and found that combination therapy is effective, with good tolerability.
