The association between vascular endothelial growth factor (VEGF) gene polymorphisms and risk of cancer has been investigated in several studies published previously; however, the individual results are inconclusive. Therefore, we performed a meta-analysis to establish evidence for an association between the VEGF -634 G/C polymorphism and risk of cancer. We searched PubMed, Medline, and Korean Studies Information Service System databases and identified 29 case-control studies, containing data of 25,324 individuals, for this meta-analysis.
Vascular endothelial growth factor
The aim of this study was to explore whether vascular endothelial growth factor (VEGF) polymorphisms confer susceptibility to psoriasis. Meta-analyses were conducted to examine the associations between the +405 C/G, -460 C/T, -1154 A/G, and -2578 A/C polymorphisms of VEGF and psoriasis using allele contrast and recessive, dominant, and additive models. Seven studies on VEGF polymorphisms and psoriasis involving 1956 subjects (psoriasis patients 665, controls 1291) were included in this meta-analysis.
