Abstract

Background: Vascular endothelial growth factor (VEGF) is a mitogen for endothelial cells and a potent regulator of angiogenesis and inflammatory processes in nasopharyngeal carcinomas. In the current report, we designed a case-controlled study to evaluate whether a genetically predetermined variation in the VEGF expression may affect susceptibility and prognosis. Methods: A PCR and restriction fragment length polymorphism analysis was used to determine the variation of the - 2578 C/A promoter region in a Tunisian population of patients with nasopharyngeal carcinomas (NPC) and in healthy control subjects. Results: A significantly risk of NPC was observed for carriers of VEGF - 2578 C allele (OR = 1.4; P = 0.03). Regarding prognostic indicators, a significant association was found between - 2578 C allele carriers and the aggressive forms of NPC as defined by large tumor size (OR = 2.29; P = 0.0002) and advanced tumor stages (OR = 1.97; P = 0.02). Moreover, an association was ascertained between the VEGF polymorphism and gender. Conclusions: This is the first report on the studies of functional VEGF polymorphisms in NPC and our preliminary data suggest that this genetic variant may play a role in mediating susceptibility to NPC, as well as, in neoplastic progression, supporting our hypothesis for VEGF involvement in NPC etiology.
