VCAM1 and neoplasm: The overall median CD3+/VCAM-1+ T cell density was 8.1 cells/mm2 (range 2.7–66.0 cells/mm2) with non-statistically significant higher numbers of CD3+/VCAM-1+ T cells in the stromal compartment (11.7 cells/mm2, range 3.1–144.5 cells/mm2) compared with the tumour compartment (0.8 cells/mm2, range 0.1–12.6 cells/mm2, Fig 1B).
