Vascular endothelial growth factor (VEGF) is a potent regulator of angiogenesis and thereby involved in the development and progression of solid tumours. The association between polymorphisms of angiogenesis pathway genes and risk of breast cancer (BC) has been widely studied, but the results are not conclusive. This information is especially limited in Spanish women, so we decided to conduct a case–control study. Here, we selected four commonly studied polymorphisms in VEGF, rs3025039 (known as +936 C/T), rs1109324, rs154765 and rs833052, one polymorphism at the promoter of the VEGFR1 (−710 C/T) and another in the FGF2, rs1449683, gene to explore their association with BC susceptibility. Genotyping was performed by TaqMan SNP assays and polymerase chain reaction–restriction fragment length polymorphis (PCR-RFLP) on 453 patients and 461 controls in a population from Valencia (Spain). We observed that women carriers of +936 CT + TT VEGF genotypes have a protective effect concerning this disease (p = 0.014; OR 0.67, 95% CI 0.48–0.92) in the global group of patients. The haplotype TGAC of VEGF (rs3025039, rs1109324, rs154764 and rs833052) shows a reduction of the risk to develop BC (p = 3e−04; OR 0.48, 95% CI 0.32–0.72). Furthermore, we found that carriers of −710 CT + TT VEGFR1 genotypes have also a protective effect (p = 0.039; OR 0.55, 95% CI 0.31–0.98). When we stratified by groups of ages these associations were maintained. Our data report for the first time the association of the polymorphism −710 C/T VEGFR1 with BC. Additional experiments focused on VEGF-A, VEGFR1 and sVEGFR1 gene expression demonstrated that carriers of T allele at −710 C/T VEGFR1 genotype have higher levels of sVEGFR1/VEGF-A than the C/C genotype carriers. This was consistent with the hypothesis that this polymorphism may act as low penetrance risk factor. The data provided suggest that +936 C/T VEGF and −710 C/T VEGFR1 genotypes are likely important genetic markers of susceptibility to BC.
