Abstract :

Cervical cancer is the third most prevalent type of cancer among women worldwide. Cervical human papillomavirus (HPV)â??s infection and persistence are essential factors for this type of disease. Nevertheless, HPV infection alone is not sufficient to cervical pathogenesis, as other necessary cofactors related to the activation of some intracellular and extracellular mechanisms are required to trigger and continue the progressive process of cervical lesions. One of these cofactors is the active role of matrix metalloproteinase (MMP), a family of endopeptidases able to degrade both extracellular matrix components and the basement membrane, and to induce tumor growth factors. These combined actions leads therefore to invasion and metastasis. Despite the extensive literature on MMPs, there is a paucity of studies on the specific MMPs mechanisms in cervical lesions, and its association with high-risk HPV oncoproteins. MMPs are important for their role in carcinogenesis, as well as potential predictive biomarkers for detection and prognosis of cervical lesions. This is due to the fact that intraepithelial lesions overexpressing certain types of MMPs tend to progress to invasion. Material for analysis of MMPs can be obtained by cytological brush at the time of the Pap smear collection, as well as colposcopy and biopsies. Further studies on the frequency of MMP genesâ?? polymorphisms can also serve as an additional tool for predictive analysis among patients with cervical intraepithelial lesions.
