Significance expression and relationships with endothelin-1, matrix metalloproteinase-9 in the laryngeal carcinoma / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To evaluate the expression of endothelin-1(ET-1) and matrix metalloproteinase-9 (MMP-9) in laryngeal carcinoma and their correlations with clinical features.@*METHOD@#The expression of ET-1 and MMP-9 was detected by immunohistochemical method in 58 specimens of laryngeal carcinoma, 28 specimens of polyps of vocal cord and 19 specimens of normal laryngeal tissues.@*RESULT@#The expressions of ET-1, MMP-9 in laryngeal carcinoma were remarkably higher,compared to polyps of vocal cord and normal laryngeal tissues (P < 0.05). The expression of ET-1, MMP-9 was associated with clinical stage, T stage and lymph node metastasis. Expression levels of ET-land MMP-9 correlated significantly with each other (r(s) = 0.693, P < 0.05).@*CONCLUSION@#The expression of ET-1 and MMP-9 may be the vital indexes in laryngeal carcinoma.
