Abstract: Objective To explore the expression of MMP2 and its correlation with the clinical features and prognosis of
endometrial adenocarcinoma. Methods We collected paraffin-embedded samples from 81 patients with endometrial
adenocarcinoma aged 32 to 80 years to examine the expression of MMP2 using immunohistochemistry. The correlation of
MMP2 expression with the clinical characteristics and prognosis of the patients was analyzed. Results MMP2 protein was
expressed in the cytoplasm of the tumor cells. MMP2 over-expression was negatively correlated with tumor differentiation (P=
0.015) and prognosis (P=0.041) of endometrial adenocarcinoma. Conclusion MMP2 over-expression is a potential malignant
biomarker in endometrial adenocarcinoma.
