14、研究表明,肺癌已成为中国恶性肿瘤死亡的首要原因,非小细胞肺癌(non-small cell lung cancer,NSCLC)约占全部肺癌的80%,NSCLC的发病率呈上升趋势,以老年人为主要发病群体1。大部分NSCLC 患者在确诊时已处于中晚期,错过了手术治疗的最佳时机,5 年生存率较低。因此,如何提高晚期NSCLC患者的治疗效果是目前临床研究的重点之一。化疗是晚期NSCLC患者的主要治疗方法,吉西他滨+顺铂(GP)方案是常用的化疗方案,但耐药性和患者耐受问题仍亟待解决,也是影响治疗效果的关键。近年来免疫治疗为晚期NSCLC患者的治疗提供了新方向2。程序性死亡受体 1(programmed
15、 cell death 1,PDCD1,也称 PD-1)抑制剂是目前研究较多的免疫治疗药物,研究发现,PD-1 抑制剂辅助治疗晚期 NSCLC 患者能够有效提高肿瘤控制率3-4。信迪利单抗是新型PD-1抑制剂,具有亲和力好、持久稳定以及靶点占位率高等优势,是目前较为常用的免疫治疗药物5。本研究探讨信迪利单抗对晚期NSCLC患者T淋巴细胞亚群的影响及其治疗效果,现报道如下。1 1资料与方法资料与方法1 1.1 1 一般资料一般资料收集2019年7月至2021年12月河南科技大学第一附属医院与河南省人民医院收治的晚期NSCLC 患者的病历资料。纳入标准:临床症状表现为不同程度的疲乏、体重下降、食欲
