Studies have revealed improved objective response rates, progression-free survival, and overall survival with immune checkpoint inhibitors when used in both first and subsequent-line settings. Unfortunately, only a subset of unselected patients with lung cancer responds to these therapies. An important area of ongoing research is to identify biomarkers that can predict which patients are most likely to derive clinical benefit. This review will discuss established and emerging biomarkers from some of the clinical trials that have demonstrated the efficacy of immune checkpoint inhibitors for the treatment of both NSCLC and SCLC.
