Diagnostic Potential of Selected Matrilysins and Stromelysins in the Diagnosis of Gynecological Malignancies Based on ROC Curve Analysis.

Matrilysins and stromelysins play a vital role in cancer, facilitating tumor invasion and metastasis. The aim of this study was to investigate the diagnostic significance of selected matrilysins and stromelysins in comparison to routine tumor markers in gynecological malignancies, relative to a control group (benign tumors and healthy women). Preoperative plasma levels of selected metalloproteinases were determined using ELISA, while levels of CA125, SCC-Ag, and HE4 by CMIA. In endometrial and cervical cancers, matrilysins (MMP-7 and MMP-26) exhibited higher diagnostic utility than routine markers. Similarly, all stromelysins in cervical cancer outperformed CA125; furthermore, MMP-10 also outperformed SCC-Ag, achieving the highest diagnostic utility among all parameters tested in cervical cancer. For ovarian cancer, diagnostic utility remained highest for routine markers. In endometrial and cervical cancers, the AUCs for all studied parameters exceeded those of standard markers, while in ovarian cancer, MMP-7 had an AUC higher than HE4 and comparable to CA 125. Combined analysis of the studied parameters in diagnostic panels demonstrated that their introduction into routine diagnostics could provide tangible benefits in the detection of malignant gynecological lesions, especially the combination of MMP-7 or MMP-10 with routine markers. These results indicate the usefulness and high diagnostic power of selected MMPs in the detection of these malignancies.
