摘要
肿瘤免疫治疗是近年肿瘤治疗领域的研究热点,尤其是免疫检查点抑制剂的成功开发与应用,更是将肿瘤免疫治疗带入了一个新时代。与化疗、放疗、靶向治疗等常规治疗方法直接作用于肿瘤细胞不同,免疫检查点抑制剂是通过阻断肿瘤微环境中免疫检查点通路,激发肿瘤特异性T细胞功能,从而改善内源性抗肿瘤免疫,达到抗肿瘤效果。现在已有多种程序性死亡受体1(PD-1)/程序性死亡受体配体1(PD-L1)单抗获得美国食品药品监督管理局(FDA)批准用于临床抗肿瘤治疗;但PD-1/PD-L1单抗在临床应用中也面临诸多挑战,如疗效预测生物标志物的选择和联合治疗等。本文对PD-1/PD-L1通路的免疫学机制、PD-1/PD-L1通路与肿瘤免疫逃逸以及目前经FDA批准的PD-1/PD-L1单抗研究现状作一综述,并讨论了目前比较热门的预测PD-1/PD-L1单抗疗效的生物标志物的研究进展。
