Immunohistochemical PD-L1 staining (Magnification: 10 x 40). The patient's expression level of PD-LI was detected using the VENTANA PD-L1 (SP263) Assay. The brown cells in the immunohistochemical staining for PD-L1 are positive cells, including tumor cells (TCs) with membrane staining at any intensity and immune cells (IC) in the tumor area, such as lymphocytes and macrophages. After counting the positive cells, the corresponding proportion was calculated according to the formula. Tumor Proportion Score (TPS), which is the percentage of viable tumor cells showing partial or complete membrane staining at any intensity. Combined positive score (CPS) = (positive TC + positive IC)/total tumor cells x 100.
