Abstract

Background: Breast cancer is one of the leading causes of cancer mortality in women worldwide. Despite significant advances in cancer treatment, mortality results from local invasion and/or distant metastasis. Aim: To evaluate EMMPIRIN (CD147) and matrix metalloproteinase-9 (MMP9) immunohistochemical expressions significance in invasive ductal breast carcinoma cases in relation to other clinicopathological parameters. Materials and Methods: The study included 50 specimens of surgically resected breast carcinomas in which the expression of CD147and MMP9 was assessed. The results were compared statistically with chi-square (χ2) and Fisher exact test. Results: CD174 overexpression showed significant association with poorly differentiated tumors, staging, presence of nodal metastasis and high Ki67 expression. There was a significant correlation between high MMP9 expression and pathological variables as tumor staging, positive nodal metastasis, low ER expression and high HER2 expression. Conclusion: The results of this study suggest that high expressions of EMMPRIN and MMP9 correlate to poor prognostic parameters. Targeted therapy might improve the prognosis of patients with CD147 and MMP-9 overexpression.
