Because of the high density of the immune infiltrate in our specimens, specific quantification, that is, a differential distinction or infiltration proportion difference of the immune cells, could not be performed on hematoxylin and eosin-stained slides or for the immunohistochemical staining of CD8+ T cells and CD68+ and CD163+ macrophages, which were all highly represented in cancer samples. Here, CD8A is linked to cancer.
