Abstract:
Objective To study the expressions of matrix metalloproteinase-2(MMP-2)and vascular endothelial growth factor (VEGF)in laryngeal carcinoma and their clinicopathological significance.Methods The immuno-histochemical technique was used to detect the expression staining results of MMP-2 and VEGF in 54 cases of laryngeal carcinoma,23 cases of polyps of vocal cord and 1 5 cases of normal laryngeal mucous tissues verified by clinicopathology under the automatic image analyzer.Results The ex-pression rates of MMP-2 and VEGF were 72.22%(39/54)and 70.37%(38/54)in the laryngeal carcinoma tissue,which were sig-nificantly higher than 47.83% and 39.13% in polyps of vocal cord and 40.00% and 46.67% in the normal laryngeal tissues respec-tively,the differences between them had statistical significance(P<0.05).The expressions of MMP-2 and VEGF had certain corre-lation with the clinical stage,lymph node metastasis and.infiltration depth of laryngeal carcinoma.Conclusion MMP-2 and VEGF may jointly participate in the process of infiltration and metastasis in laryngeal and have certain relation with the tumorous invasive growth.
