Abstract
Introduction: Vascular endothelial growth factor (VEGF) is thought to be an important angiogenic factor that involved in tumor growth, progression and metastasis. Objective: The present study evaluate the relation between tissue expression, serum and salivary levels of VEGF in head and neck squamous cell carcinomas (HNSCCs) and their correlation with clinicopathologic features. Method and Materials: Samples were collected from 30 patients with HNSCCs and 24 healthy volunteers. Immunohistochemical analysis was used for tissue expression and ELISA was employed to measure serum and salivary levels. Results: No VEGF staining was observed in normal tissues; whereas VEGF expression was seen in six patients (20%). Mean serum level of VEGF was 83.7?104.47 in patients and 50.04?32.94 in controls. Mean salivary level of VEGF was 174.41?115.07 in patients and 149.58?101.88 in controls. No significant difference was found by Mann-Whitney statistical test between controls and patients (respectively P: 0.411, P: 0.944). No correlation was found between VEGF tissue expression and its serum and salivary level. Conclusion: In the present study, over expression of VEGF was found in HNSCC patients that suggest its role in the pathogen
