Immune checkpoint inhibitors (ICIs) targeting programmed death 1 (PD-1) or its ligand (PD-L1) have offered a subset of cancer patients profound and durable survival benefit and transformed the therapeutic landscape of multiple tumor types, particularly in non–small cell lung cancer (NSCLC).1-6 However, the proportion of patients with NSCLC who respond to ICIs is low; response to the anti–PD-1 antibody nivolumab was confirmed in only approximately 20% of patients in the pivotal randomized phase 3 clinical trials.1,2 More troublesome, PD-1/PD-L1 inhibitors can cause immune-related adverse effects7 as well as hyperprogressive disease.8 Therefore, there have been substantial attempts to discover and validate predictive biomarkers to identify patients who may benefit from PD-1/PD-L1 inhibitors by integrating information from tumors, the tumor microenvironment (TME), and the host immune system.9 To date, tumor PD-L1 expression using companion diagnostics is the only approved biomarker to indicate NSCLC patients for PD-1 axis blockade.  M, ¥çš„に作った抗体で蓋をしてしまうことで結合を阻害しT細胞を抑制させない薬が認可され …  et al.
