Population-based case-control study of VEGF gene polymorphisms and breast cancer risk among Chinese women.
Vascular endothelial growth factor (VEGF) is a major angiogenic factor involved in a number of pathologic processes, including neovascularization, a crucial step in the development of solid malignancies. Using data and specimens collected in the Shanghai Breast Cancer Study, a population-based case-control study conducted in urban Shanghai, China from 1996 to 1998, we evaluated the association of VEGF gene polymorphisms with breast cancer risk. Included in this study were 1,093 cases and 1,184 age-matched controls who had completed an in-person interview and donated a blood sample to the study. Polymorphisms in the promoter region (T -460C), 5' untranslated region (C +405G), and 3'untranslated region (C936T) were genotyped using the Taqman allelic discrimination assay. No statistically significant case-control difference was found for the C +405G and T -460C polymorphisms. However, the C936T polymorphism was associated with a reduced risk of breast cancer. Compared with CC genotype carriers, women who had the TT genotype showed a decreased risk [odds ratio (OR), 0.65; 95% confidence interval (95% CI) 0.41-1.02], and the inverse association was restricted to premenopausal women (OR, 0.45; 95% CI, 0.25-0.79). Six common haplotypes were identified. Compared with the most common haplotype (-460T/405C/936C), the -460T/405G/936T haplotype was associated with a reduced risk of breast cancer (OR, 0.67; 95% CI, 0.43-1.04), particularly in premenopausal women (OR, 0.47; 95% CI, 0.27-0.81). Our study suggests that the VEGF C936T polymorphism might be a susceptibility factor for breast cancer among Chinese women.
