While analytical comparisons have demonstrated a reasonable agreement among most of the available PD-L1 detection assays (VENTANA PD-L1 [SP263] Assay, Dako PD-L1 IHC 22C3 pharmDx, and Dako PD-L1 IHC 28–8 pharmDx) [28], lower sensitivity has been reported with the VENTANA PD-L1 (SP142) Assay for determining tumor proportion scores on TCs in comparison with other assays [43]. Here, CD274 is linked to neoplasm.
