摘要: 目的:初步探讨应用微粒-经肝动脉化疗栓塞(m-TACE)治疗肝细胞癌(HCC)术后外周血中CD4+程序性死亡受体1(PD-1)、CD8+PD-1的变化及意义。
方法:选取 2021—2022年北京清华长庚医院肝胆胰中心临床资料完整的20例有 m-TACE治疗指征的中晚期HCC患者(HCC组),选择非酒精性肝硬化患者及健康志愿者各 12 例作为肝硬化组和健康组。应用流式细胞术检测健康组、肝硬化组和HCC患者m-TACE术前与术后1~2周外周血中CD4+PD-1、CD8+PD-1表达情况。
结果:HCC组外周血CD4+PD-1、CD8+PD-1表达均明显高于肝硬化组及健康组。HCC患者经m-TACE治疗后1~2周外周血CD4+PD-1表达由治疗前(38.65±8.56)%下降至(31.65±5.81)%(P<0.05),同样CD8+PD-1表达也较治疗前下降[(41.17±12.12)% ∶(29.29±10.48)%,P<0.05]。m-TACE治疗后疗效好的患者术后外周血PD-1表达较低。
结论:m-TACE治疗HCC可能降低外周血CD4+/CD8+ PD-1的表达。

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.
