ABSTRACT
OBJECTIVE@#To investigate the expressions and clinical significance of Hypoxia-Inducible Factor-1alpha (HIF-1alpha) and angiopoietin-2 (Ang-2) proteins in laryngeal squamous cell carcinoma.@*METHOD@#Immunohistochemical technique was used to detect the expressions of HIF-1alpha and Ang-2 protein in 52 laryngeal squamous cell carcinoma and 10 normal tissues.@*RESULT@#The positive rates of HIF-1alpha and Ang-2 proteins were significantly higher in laryngeal squamous cell carcinoma than those in normal tissues (P 0.05). The level of Ang-2 expression was also correlated with TNM stage, lymph node metastasis and histological differentiation of laryngeal squamous cell carcinoma. But not related to the age and sex. There was positive correlations between both expressions of HIF-1alpha and Ang-2 proteins (r = 0. 333, P < 0.01).@*CONCLUSION@#High expressions of HIF-1alpha and Ang-2 proteins in laryngeal squamous cell carcinoma may play an important role in tumor growth, invasion and metastasis.
