Evaluation of PD-L1 Expression in Tumor Tissue of Patients with Lung Carcinoma and Correlation with Clinical and Demographic Data

<div>Photomicrographs of PD-L1 immunohistochemical expression in IICs in non-small-cells lung cancer (magnification/scale bar: 400x/50<i>μ</i>). (a) Absence of PD-L1 expression; (b) focal PD-L1 expression (&lt;5% of tumor surface); (c) diffuse PD-L1 expression (&gt;5% of tumor surface). Observe the dendritic cytoplasm of some cells; (d) Positive Control. Arrows show positive staining cells.</div>
