最新发布的中国癌症疾病负担报告显示,肺癌持续多年位居我国肿瘤死亡率首位[1]。目前非小细胞肺癌患者晚期一线治疗方案已为程序性死亡分子1(Programmed Cell Death Protein 1,PD-1)/程序性死亡受体-配体1(Programmed Cell Death-Ligand 1,PD-L1)抑制剂单药或联合含铂化疗。前期研究发现,携带丝氨酸-苏氨酸激酶11(Serine-threonine kinase 11, STK11)、Kelch样环氧氯丙烷相关蛋白1(Kelch-like ECH-associated protein 1,KEAP1)等基因突变的非小细胞肺癌患者表现出更差的临床预后,对免疫治疗反应不佳,生存期低于未携带上述突变肺癌人群[2-4],提示该部分人群仍存在未满足的临床需求。
