Abstrakt: The content of vascular endothelium growth factor is significantly increased, while the level of matrix metalloproteinase-2 is 2-fold reduced in ovarian cancer tissue compared to benign tumors. A trend to an increase in the levels of matrix metalloproteinases 7 and 9 and reduction of vascular endothelial growth factor type 2 receptors in tumor tissue was also detected. A highly significant negative correlation between the levels of vascular endothelial growth factor and matrix metalloproteinase 2 and positive correlations between vascular endothelial growth factor and matrix metalloproteinase 7, vascular endothelial growth factor and matrix metalloproteinase 9, matrix metalloproteinase 2 and vascular endothelial growth factor type 2 receptors were revealed. In the tumors assayed after preoperative therapy, relative normalization of the studied parameters was observed: the level of vascular endothelial growth factor decreased significantly, while the levels of matrix metalloproteinase 2 and vascular endothelial growth factor type 2 receptors increased. The levels of the markers differed significantly in ovarian tumors of different histological types, and the levels of vascular endothelial growth factor type 2 receptors were higher in patients with stage III compared to stage I and the content of matrix metalloproteinase 7 was higher in stage III compared to stage II cancer.
