Predictive factors for the clinical effect of PD-1/PD-L1 checkpoint inhibitors in treatment of hepatocellular carcinoma / 临床肝胆病杂志

ABSTRACT

At present, there is still a lack of uniform treatment strategies for hepatocellular carcinoma (HCC). Immunotherapy, especially PD-1/PD-L1 checkpoint inhibitors, is a novel therapy for HCC and can bring survival benefits to patients with advanced HCC. However, research data show that only a small number of HCC patients can benefit from this treatment regimen. To date, few biomarkers have been reported to predict the clinical effect of PD-1/PD-L1 checkpoint inhibitors in HCC patients. This article reviews the biomarkers studied for HCC and other tumors and explores the possible predictive factors for the clinical effect of PD-1/PD-L1 checkpoint inhibitors in HCC, in order to optimize the selection of treatment population and improve the clinical effect of PD-1/PD-L1 checkpoint inhibitors in the treatment of HCC.
