Matrix metalloproteinase 9 (MMP9) and CD147 play a role in invasion and metastasis of many types of human malignancies. The correlation of the expression of MMP9 and CD147 with invasion and metastasis of invasive squamous cell carcinoma (SCC) of the uterine cervix has not been examined. In the present study, RT-PCR assay was used to detect the expression level of MMP9 mRNA semiquantitatively, and immunohistochemical stain was adapted to evaluate the score of CD147 on the cell membrane or in the cytoplasm of tumor cells of 65 cases of invasive squamous cell carcinoma of the uterine cervix and 21 cases of chronic cervitis tissues. MMP9 and CD147 expression in correlation with invasion, metastasis, and differentiation of invasive SCC of the uterine cervix was analyzed statistically. We found that MMP9 and CD147 expression was elevated significantly in tumor tissue compared to the control (cervical epithelium of chronic cervitis) (P<0.01). In the comparison of MMP9 and CD147 expression in 47 cases with lymph node metastasis and 18 cases without lymph node metastasis, there was a significantly higher expression of MMP9 and CD147 in the group with lymph node metastasis (P<0.05 for MMP9, P<0.01 for CD147). MMP9 expression was significantly higher in 24 cases of poor differentiation than in 41 cases of moderate differentiation (P<0.05). No difference was found in CD147 expression between poor and moderate differentiation (P>0.05). No significant difference in MMP9 and CD147 expression levels was obtained between 26 cases of FIGO stage I tumors and 39 cases of stage II tumors (P>0.05 for MMP9, P>0.05 CD147). There was no correlation between MMP9 or CD147 expression levels and the resected tumor size (P>0.05). The positive correlation (r=0.568, P<0.001) of MMP9 expression and CD147 score was seen in the tumor tissues of 65 cases. The data in this study show that MMP9 and CD147 expression are correlated with invasion, metastasis of squamous cell carcinoma of the uterine cervix, and that MMP9 expression is correlated with poor differentiation of invasive squamous cell carcinoma of the uterine cervix.
