NCAM1 and neoplasm: Furthermore the absolute number of CD56− T cells was similar at all three sites sampled (macroscopically normal liver tissue, 595 cells/mg, peritumoural liver 760 cells/mg and tumour 626 cells/mg p = ns), whilst the intratumoral NK cell number was significantly lower than the macroscopically normal tissue (145 cells/mg vs 832 cells/mg p = 0.026) and there was a trend towards a lower number of CD56+ T cells in the tumour (92 cells/mg) compared to the macroscopically normal liver (285 cells/mg) (Figures 2C, E, G).
