Matrix Metalloproteinases and Their Tissue Inhibitors in Blood Serum of Patients with Endometrial Cancer: Clinical and Morphological Correlations.

In patients with endometrial cancer (N=94), endometrial polyps (N=28), endometrial hyperplasia (N=25), and healthy women (N=77), the serum contents of MMP-2, MMP-7, MMP-9, TIMP-1, and TIMP-2 were measured by ELISA. Both carcinoma and benign neoplasms were accompanied by significant elevation of MMP-7 and TIMP-2 in blood serum. The greatest elevation (in comparison with the control) was observed for MMP-7, although serum concentration of this marker was practically identical in patients with carcinoma and benign tumors.
