Methods: The expression of EphB4 and HIF-1α was detected in 54 specimens of lung cancer by using streptavidin-peroxidase (SP)immunohistochemical method, and 10 normal lung tissues as control. Results: Among the 54 cases of lung cancer, the positive rate of EphB4 was 50.0%; 42.6% of the tumors were positive for HIF-1α. The expression of these two kinds of proteins was related to gross types, differentiation and clinical stages (P〈0.05), but not to histological classification, age, sex and lymphoid metastasis (P〉0.05). A highly positive correlation was observed between the expression of EphB4 and HIF-1α (P〈0.01). Conclusion: Overexpression of EphB4 and HIF-1α may play an important role in the pathogenesis, progression and malignant degree of lung cancer. Detection of EphB4 and HIF-1α expression might be helpful to predict prognosis of patients with lung cancer.展开更多
