The overall median CD3+/ICAM-1+ T cell density was 5.0 cells/mm2 (range 0.1–144.9 cells/mm2), with non-statistically significant higher numbers of CD3+/ICAM-1+ T cells in the stroma (4.8 cells/mm2, range 0.1–373.3 cells/mm2) than in the tumour compartment (1.7 cells/mm2, range 0.0–22.1 cells/mm2, Fig 1C). Here, ICAM1 is linked to neoplasm.
