The number of tumour cells expressing CD18 was positively correlated with the intensity of the CD18 expression (r = 0.642; P = 0.000), the intensity of the lymphocytic infiltration (r = 0.303; P = 0.014), the number of tumour cells expressing MHCII (r = 0.638; P = 0.000) and the MHCII expression pattern (r = 0.284; P = 0.022). Here, ITGB2 is linked to neoplasm.
