On FFPE, B7-H3 expression was expressed as the percentage of tumor cells with complete/or incomplete membranous staining and designated as the tumor proportion score (TPS); non-tumoral B7-H3 expression status was classified as a non-tumoral proportion score (NTPS) according to the proportion of non-tumoral cells showing cytoplasmic and/or membranous staining. This evidence concerns the gene CD276 and neoplasm.
