The Association Between VEGF +936C/T and −634G/C Polymorphisms and Breast Cancer Susceptibility, Tumor Growth, and Metastases: Evidence From 20,728 Subjects

Abstract

The relation between the polymorphisms of vascular endothelial growth factor (VEGF) and breast cancer remains inconclusive. In our meta-analysis based on 10,340 breast cancer patients and 10,388 controls, we found breast cancer susceptibility was elevated in individuals carrying the VEGF +936C allele, especially in Asians, and the +936CC increases tumor growth. The G allele of –634G/C polymorphism reduces breast cancer susceptibility in Asians, and breast cancer patients of –634GG genotype has decreased tumor growth. These results suggest that both the VEGF +936C/T and –634G/C polymorphisms influence breast cancer susceptibility and tumor growth, instead of metastasis.
