ABSTRACT
<p><b>OBJECTIVE</b>To study the expressions and clinical significances of p-extracellular regulated kinase(P-ERK)1/2 and matrix metalloproteinase-9(MMP-9)in cervical squamous cell carcinoma.</p><p><b>METHODS</b>The expressions of P-ERK1/2 and MMP-9 in 30 cases with chronic cervicitis, 45 cases with cervical intraepithelial neoplasia (CIN), and 58 cases with cervical squamous cell carcinoma were detected by immunohistochemical method.</p><p><b>RESULTS</b>The positive rates of P-ERK1/2 and MMP-9 in chronic cervicitis, CIN, and cervical squamous cell carcinoma were 0 and 0, 28.9% and 24.4%, 77.6% and 65.5%, respectively, showing significant differences among these three groups (χ(2)= 54.393,p=0.003;χ(2)=40.968,p=0.005). The positive rates of P-ERK1/2 and MMP-9 in patients at clinical stages 2-3, at G3, with lymphatic metastasis, or with a tumor diameter greater than 4 cm were significantly higher than those at clinical stage 1(p=0.015,p=0.002), at G1-G2(p=0.013,p=0.017), without lymphatic metastasis (p=0.017,p=0.021), or with a tumor diameter less or equal than 4 cm in cervical squamous cell carcinoma(p=0.008,p=0.004). There was a positive correlation between P-ERK1/2 and MMP-9 in cervical squamous cell carcinoma (χ(2)=8.955,p=0.006).</p><p><b>CONCLUSIONS</b>The expressions of P-ERK1/2 and MMP-9 increase gradually with the progression of cervical squamous cell carcinoma. The over expressions of P-ERK1/2 and MMP-9 may promote the infiltration of cervical squamous cell carcinoma and lymphatic metastasis, druing which these two enzymes may exert their effects in a synergistic manner.</p>
