The Significance of EphB 4 and EphrinB 2 Expression and Survival in Head and Neck Squamous Cell Carcinoma

Conclusions: EphB4 and EphrinB2 overexpression is associated with poor overall survival in patients with HNSCC. Our results are the first to demonstrate an association between decreased survival and elevated expression of the receptor tyrosine kinase EphB4 and its ligand EphrinB2, suggesting that EphB4 and EphrinB2 may be used as biomarkers to predict prognosis and as targets in future HNSCC therapies.
