Abstract
With the deeper understanding of the pathophysiology and pathogenesis of non-small cell lung cancer (NSCLC) which threatens human health, NSCLC treatment has entered a new era. Transition from traditional treatment based on surgery, radiotherapy and chemotherapy to individualized and precise targeted therapy and safer and more effective immunotherapy. Immune checkpoint inhibitor therapy has been approved as a first-line or second-line treatment for advanced NSCLC, and has achieved extraordinary clinical results. Meanwhile, other types of immunotherapy are rarely explored in NSCLC. Chimeric antigen receptor modified T cells (CAR-T cells) perform well in treating several hematological malignancies. However, it is not ideal for treating patients with solid tumors including NSCLC. This review aims to systematically explain the latest progress of CAR-T in the treatment of NSCLC, mainly including: CAR molecular target selection, CAR-T function enhancement and related toxicity management, as well as the difficulties and prospects of CAR-T treatment of NSCLC. It aims to open up new perspectives and unique ideas for the immunotherapy of NSCLC, and contribute to the building of tumor immunotherapy. .Entities:

1CAR-T免疫疗法治疗NSCLC。CAR-T细胞疗法的主要步骤包括:①分离体内的T细胞;②嵌合抗原受体修饰T细胞(嵌合抗原受体CAR主要包括胞内激活区和共刺激区域、跨膜区、胞外的铰链区和抗原结合区);③CAR-T细胞的体外扩增;④CAR-T细胞回输至体内杀伤肿瘤细胞。
CAR-T immunotherapy for NSCLC. The main steps of CAR-T cell therapy include: (1) isolating T cells in vivo; (2) modifying T cells with chimeric antigen receptor (CAR mainly includes intracellular activation area and co-stimulation area; transmembrane area; extracellular hinge area and antigen binding area); (3) expansion of CAR-T cells in vitro; (4) reinfusion of CAR-T cells to kill tumor cells in vivo.
