Description: It is a systematic review and meta-analysis of fourteen contemporary phase II and phase III trials evaluating outcomes following PD-1/PD-L1 inhibitor therapy (immunotherapy-exclusive or chemotherapy-immunotherapy combination regimens) in locally advanced and metastatic NSCLC with < 1% PD-1 expression. This particular subset of patients makes up 50-60% of advanced NSCLC patients for whom the optimal therapy regimen is yet to be defined. In addition, histologic subtypes and lines of treatment further complicate the treatment strategy.
