    Abstract:
    AIMS: Vascular endothelial growth factor (VEGF) protein plays an important role in tumor development and progression. Polymorphisms in the VEGF gene may lead to over- or underexpression of the protein and may be associated with either risk or progression of malignancy. The aim of this case-control study is to identify and quantify the correlation between VEGF polymorphisms and renal cell carcinoma (RCC). RESULTS: Restriction fragment length polymorphism methods were used for the analysis of VEGF polymorphisms at -2578 and +936 positions in the promoter and 3'-untranslated regions, respectively. The VEGF -2578 A-allele was associated with an increased risk of RCC (odds ratio: 1.6; 95% CI: 1.2-2.3) and A-carrier genotypes were strongly correlated (odds ratio: 2.7; 95% CI: 1.5-4.7) with higher risk. Comparison of VEGF +936 C/T polymorphism between patient and control groups revealed no association with renal carcinoma. Both VEGF -2578 C/A and VEGF +936 C/T polymorphisms showed no significant association with the histopathological parameters of RCC. CONCLUSIONS: This study shows that VEGF -2578 A-allele and A-carrier genotypes are associated with an increased risk of RCC. In groups with higher incidence of RCC, a screening test for this polymorphism may be recommended in conjunction with other established markers.
