Abstract：Objective To investigate the expression and clinical significance of nuclear factor kappa -B ( NF-κB ) and matrix metalloproteinase ( MMP-9 ) in cervical carcinoma .Methods The expression levels of NF-κB and MMP-9 were detected by immunohistochemistry in 80 cases of cervical carcinoma (CSES),70 cases of cervical intraepithelial neoplasm (CIN) and 50 cases of normal cervical tissues (NCE).The correlation between their expression levels and clinical pathological characteristics was analyzed .Results The expression levels of NF-κB and MMP-9 in CSES were significantly higher than those in CIN and NCE ( P <0.05).The expression levels of NF-κB and MMP-9 were correlated to the pathological classification , clinical staging and lymph node metastasis of cervical carcinoma ( P <0.05),however,which were not related to patient ’ s age and histological types,moreover the expression of NF-κB was positively related with that of MMP-9 ( P <0.05).Conclusion The overexpression of NF-κB and MMP-9 exists in patients with cervical carcinoma ,which may play an important role in the pathogenesis ,development ,invasion and metastasis of cervical carcinoma and NF-κB and MMP-9 can be used as the indexes of diagnosis and prognosis evaluation for cervical carcinoma .
