Study design:

Single arm 

研究目的:

1. 对 PDL-1 低表达接受免疫联合化疗进展 NSCLC 患者,原耐药方案基础上继续应用免疫检查点抑制剂联合LD-RT进行前瞻性单臂临床研究,评价ORR及PFS; 2. 探索 LD-RT 放疗后或同步给予免疫检查点抑制剂临床疗效,采集患者接受LD-RT前后影像资料,测量病灶变化,评价肿瘤缩小达到 CR+PR 比例和DCR(CR+PR+SD); 3. 对临床符合病理穿刺取材患者,比较接受 LD-RT 放疗前后病灶中 T-和 NK 细胞浸润变化情况,即在适用的情况下,收集 LD-RT 前后的活检,并固定福尔马林,用多重免疫荧光(multi-IF)分析免疫细胞浸润:CD3、CD8、CD4、CD56 和Ki67;  

Objectives of Study:

1. For patients with advanced NSCLC with low PDL-1 expression receiving immunotherapy combined with chemotherapy, a prospective single-arm clinical study with immune checkpoint inhibitor combined with LD-RT was continued on the basis of the original drug resistance regimen to evaluate ORR and PFS; 2. To explore the clinical efficacy of immune checkpoint inhibitors after radiotherapy or simultaneous administration of LD-RT, collect imaging data of patients before and after receiving LD-RT, measure lesion changes, and evaluate tumor shrinkage to CR+PR ratio and DCR (CR+PR+SD); 3. Compare the changes of T- and NK cell infiltration in the lesion before and after receiving LD-RT radiotherapy for patients with clinically consistent pathologic puncture sampling, that is, if applicable, biopsies before and after LD-RT were collected, formalin was fixed, and immune cell infiltration was analyzed by multi-immunofluorescence (multi-IF) : CD3, CD8, CD4, CD56 and Ki67;
