Clinical Response to Sequential HAIC and TAE Combined with Tislelizumab and Lenvatinib Treatment for Hepatocellular Carcinoma Involving Lung Metastases: A Case Report

This is the authors' abstract. We don't add key points for this paper.

Lung metastasis is common in hepatocellular carcinoma (HCC) and is typically associated with a poor prognosis. In this report, we present a case of advanced HCC in a 46-year-old Chinese male with lung metastases. The patient received two cycles of sequential hepatic arterial infusion chemotherapy and transarterial embolization in combination with lenvatinib (a tyrosine kinase inhibitor) and tislelizumab (a programmed cell death protein 1 immune checkpoint inhibitor). After three months of treatment, the intrahepatic tumors showed a partial response, while the bilateral lung metastases exhibited a complete response. Concurrently, levels of alpha-fetoprotein and protein induced by vitamin K absence or antagonist-II decreased to normal levels. Systemic treatment with lenvatinib and tislelizumab was continued for 10 months. This case underscores the potential of combination therapies for advanced HCC with lung metastases and provides a novel perspective on a therapeutic approach involving sequential hepatic arterial infusion chemotherapy and transarterial embolization with immune checkpoint and tyrosine kinase inhibitors.
