Fig. 4From: Tumor Area Positivity (TAP) score of programmed death-ligand 1 (PD-L1): a novel visual estimation method for combined tumor cell and immune cell scoringPD-L1 expression status around the 5% TAP score cutoff. Top panel: PD-L1 negative case, TAP score <5% (A H&E staining, B PD-L1 staining). Bottom panel: PD-L1 positive case, TAP score >5% (C H&E staining, D PD-L1 staining). H&E hematoxylin and eosin, IC immune cells, PD-L1 programmed death-ligand 1, TAP Tumor Area PositivityBack to article page
