Abstract: Objective:To explore the changes and significance of CD4+programmed death receptor 1(PD-1) and CD8+PD-1 in peripheral blood after hepatocellular carcinoma(HCC) patient streated with microparticles transcatheter arterial chemoembolization(m-TACE).
Method:From 2021 to 2022, 20 patients with intermediate and advanced HCC with indications for m-TACE treatment were selected from the Hepatobiliary and Pancreatic Center of Beijing Tsinghua Chang Gung Hospital (HCC group), and 12 patients with non-alcoholic cirrhosis and 12 healthy volunteers were selected as cirrhosis group and healthy group. Flow cytometry was used to detect the expression of CD4+PD-1 and CD8+PD-1 in peripheral blood of healthy, cirrhotic, and liver cancer patients before and 1-2 weeks after m-TACE.
Result:The expression of CD4+/CD8+PD-1 in peripheral blood of the HCC group was significantly higher than that of the liver cirrhosis group and the healthy group. After 1-2 weeks of m-TACE, the expression of CD4+/CD8+PD-1 of HCC patients decreased compared to before treatment(P<0.05). Patients with good therapeutic effects after m-TACE have lower expression of CD4+/CD8+PD-1 in peripheral blood(P<0.05).
Conclusion:m-TACE treatment for HCC can reduce the expression of CD4+/CD8+PD-1 in peripheral blood.
