ABSTRACT
Objective:
To investigate the expression and clinical significance of Ang-2 and MMP-7 protein in laryngeal carcinoma tissue.Method:
Immunohistochemical technique was used to detect the expression of Ang-2 and MMP-7 protein in 65 tissues of laryngeal carcinoma and 34 biopsies of adjacent non-cancerous tissue. The relationship between the expression of Ang-2 and MMP-7 and invasion, metastasis or prognosis in laryngeal carcinoma tissue was analyzed.Result:
The positive rates of Ang-2 and MMP-7 were significantly higher in laryngeal carcinoma tissue than those in adjacent non-cancerous tissue(P<0.05).The level of Ang-2 and MMP-7 expression had no significant correlations with the age and course as well as the smoking, drinking, histological differentiation of carcinoma and clinical classification (P>0.05).While the expression of Ang-2 significantly differed between patients with different T stage and clinical stage(P<0.05), and the expression of MMP-7 was notably correlated with the T stage,clinical stage and lymph node metastases (P<0.05).There was a correlation between the expression of Ang-2 and MMP-7 (P<0.05).The Kaplan-Meier survival analysis showed that patients with positive expression of Ang-2 had worse overall survival(P<0.05).However,MMP-7 expression was not related to overall survival or disease-free survival (all P>0.05).Cox regression analysis indicated that Ang-2 and MMP-7 expression were independent prognostic factors of laryngeal carcinoma.Conclusion:
Overexpression of Ang-2 and MMP-7 was observed in laryngeal carcinoma and they might be served as an objective indicator for biological behaviour and prognosis.
