Prognostic significance of expression of cyclooxygenase-2, vascular endothelial growth factor, and epidermal growth factor receptor in nasopharyngeal carcinoma

摘要

Background. The association between expression of cyclooxygenase-2 (COX-2), vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), and the long-term outcomes in treated nasopharyngeal carcinoma (NPC) was studied.
