The mean % of positive cells in primary tumour ranged from 12.79 ± 6.376% CD8+CD71+ to 50.26 ± 16.72% CD8+HLA-DR+ T-cells, in sentinel node from 3.466 ± 1.939% CD8+CD71+ to 40.55 ± 14.54% CD4+CD69+, in non-sentinel node from 3.968 ± 5.401% CD8+CD71+ to 29.46 ± 17.73% CD8+HLA-DR+ and in blood from 0.9848 ± 0.7570% CD8+CD71+ to 20.02 ± 17.97% CD8+HLA-DR+. This evidence concerns the gene CD8A and neoplasm.
