CEACAM8 and neoplasm: SARIFA-positivity is associated with lower densities of T cells, CD66b+ granulocytes, mast cells, mature monocytic cells, and M1-like macrophages but higher densities of M2-like macrophages and immature monocytic cells in the tumours, which supports the hypothesis of an immunosuppressive tumour microenvironment in SARIFA-positive tumours.
