The CD163+ cell count in the tumour region revealed much higher cell densities in both the stromal (CT: Median/SD 83.6/±421.5 cells/mm2; IF: 100.4/±462.9 cells/mm2) and intraepithelial compartments (CT: Median/SD 121/±172.1 cells/mm2; IF: 148.6/±208.6 cells/mm2). This evidence concerns the gene CD163 and neoplasm.
