The use of programmed cell death 1 ligand 1 (PD‐L1) as a predictive biomarker to select
patients to receive programmed cell death 1 (PD‐1) or PD‐L1 inhibitors in non‐small cell
lung cancer (NSCLC) is limited by the definitions of positivity, interassay agreement, and
intra‐and intertumoral heterogeneity of expression. Although PD‐L1 expression enriches for
responses, the lack of expression does not exclude clinical benefit.
