We categorized all cases into three subgroups according to the CD73 and CD8 staining: group I, high CD73 and low CD8+T cells; group II, both high CD73 and tumour infiltrating CD8+ T cells or both low CD73 and tumour infiltrating CD8+T cells; and group III, low CD73 and high tumour infiltrating CD8+ T cells. This evidence concerns the gene NT5E and neoplasm.
