| Abstrakt: | Background: Matrix metalloproteinases (MMPs) are basically a part of a large family of proteolytic enzymes. They play an important role in degrading extracellular matrix and basement membrane, which is a basic mechanism in local invasion and tumour metastasis. The aim of this study was to evaluate immunohistochemically the expression of MMP1 and MMP10 in tumour invasion locally and at distant levels, including lymph nodes at different levels in oral squamous cell carcinoma (OSCC). Materials and Methods: A total of 50 tissue samples with clinically confirmed OSCC and 15 normal oral mucosal tissues will be included in the study. Immunohistochemical staining will be performed for the demonstration of MMP1 and MMP10 in lesional tissue, perilesional tissue, and lymph nodes of different levels that were evaluated with respect to microscopic features. Results: All OSCC cases had MMP1 and MMP10 expression levels. The expression increased as the nodal level increased from level I to level V. This difference was statistically significant at P < 0.001 Both MMPs were not expressed in normal epithelial cells. There was no significant correlation between MMP1 and MMP10 expression. Conclusion: This study showed that MMP1 and MMP10 are expressed in the tissues of OSCC and may serve as prognostic indicators for the disease. Competing Interests: There are no conflicts of interest.
