| 摘 要： | 肺癌是全世界发病率及病死率最高的恶性肿瘤。近年来,针对程序性死亡受体1(programmed cell death 1,PD-1)及其配体(programmed cell death-ligand 1,PD-L1)的免疫检查点抑制剂治疗显著改善了非小细胞肺癌(non-small cell lung cancer,NSCLC)患者的预后。然而在非选择人群中免疫治疗的客观应答率仅约20%,因此选择出免疫治疗潜在的获益人群非常重要。通过免疫组织化学检测肿瘤组织中PD-L1的表达可以在一定程度上预测免疫治疗的疗效,但是其仍有一定的局限性。最新临床研究表明循环肿瘤细胞(circulating tumor cell,CTC)上PD-L1的表达(PD-L1 expression in circulating tumor cells,CTC-PD-L1)是一种潜在的独立生物标志物,其可为NSCLC的免疫治疗提供重要信息。本文将对CTC-PD-L1检测技术及其在NSCLC患者免疫治疗效果中的预测价值及最新临床研究进展进行综述。

| Abstract: | Lung cancer is the most frequent cancer and the leading cause of cancer death all around the world.Anti-programmed cell death 1(PD-1)/programmed cell death-ligand 1(PD-L1)therapies have significantly improved the outcomes of non-small cell lung cancer(NSCLC)patients in recent years.However,the objective response rate in nonscreened patients is only about 20%.It is very important to screen out the potential patients suitable for immunotherapy.Immunohistochemical staining of tumor tissue biopsies with PD-L1 antibodies can predict the therapeutic response to immunotherapy to some extent,but it still has some limitations.Recently some clinical studies have shown that PD-L1 expression in circulating tumor cells(CTC-PD-L1)is a potential independent biomarker and may provide important information for immunotherapy in NSCLC.This article will review technology for CTC-PD-L1 detection and the predictive value of CTC-PD-L1 for immunotherapy in NSCLC and review the latest clinical research progress. |
