In non-small cell lung cancer (NSCLC), high concordance with tumor cell PD-L1 expression was seen when comparing these three assays (lower tumor cell PD-L1 expression was observed with the Ventana SP142 assay comparatively); however, concordance between these assays was lower for immune cell PD-L1 expression [60]. Here, CD274 is linked to non-small cell lung carcinoma.
