Abstract

The comparative analysis of the quantity of matrix metalloproteinases (MMP) 2,7 and 9 in breast cancer is carried out; the concentration of sex hormones receptors and protein HER-2/neu are determined. Authentically high values MMP-2 and MMP-7 are found in a tumor tissue in contrast to the normal one. The elevated concentration of ММР-2 in a tumor is connected with receptor status (p < 0,05). The highest values of concentration ММР-7 and ММP- 9 are found at RE-, RP- and HER-2/neu + tumors, and also in the tumors with the size more than 4,0 cm.
