Vascular endothelial growth factor G+405C polymorphism may contribute to the risk of developing papillary thyroid carcinoma.

Background: Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy. Vascular endothelial growth factor (VEGF) is a mediator implicated with cell proliferation, differentiation and migration, and monocyte/macrophage chemotaxis.
