B7-H3 expression shows no notable correlation with major TIICs, including CD3 + , CD8 + and CD20 + TIICs in small cell lung cancer [32], whereas B7-H3 expression is positively correlated with the abundance of CD45 + and CD8 + TIICs in non-small-cell lung cancer [33]. This evidence concerns the gene PTPRC and small cell lung carcinoma.
