To assess the reliability of these approaches and harmonize PD-L1, Lantuejoul et al. (32) analyzed 41 NSCLC surgical specimens via three platforms [Dako, Ventana, and laboratory-developed tests (LDTs) are included], which involved five IHC PD-L1 detections (22C3, 28-8, SP142, SP 263, and E1L3N assays). This evidence concerns the gene CD274 and non-small cell lung carcinoma.
