CD14+, CD68+ and CD163+ cell densities in the intratumoral tumor (IT tumor) compartment (p = 0.001; p < 0.001 and p = 0.004, respectively) and peritumoral tumor (PT Tumor) compartment (p = 0.001; p = 0.003 and p < 0.001, respectively) differed between grades of differentiation. This evidence concerns the gene CD68 and neoplasm.
