Thus, together, this data suggests that the good prognostic value of NKp46 would reflect the prognostic value of NK cell infiltration in breast tumors and therefore, the good prognostic value of CD56 mRNA expression in breast tumor tissues might be at least in part due to the enhanced infiltration by NK cells and not necessarily related to the expression of this adhesion molecule in tumor cells themselves. Here, NCR1 is linked to breast neoplasm.
