Objective: To evaluate the association between 3 vascular endothelial growth factor (VEGF) gene polymorphisms and susceptibility of cervical intraepithelial neoplasia (CIN). Materials and Methods: This prospectively collected case-control study investigates three common VEGF gene polymorphisms (ie, VEGF j460 [rs833061], VEGF +405 [rs2010963], and VEGF +936 [rs3025039]) in 203 women with CIN and 209 healthy women by DNA pyrosequencing. Associations between polymorphisms and CIN risk are evaluated with univariate and multivariable models and haplotype analysis. Results: In a multivariable regression model, the variant VEGF +405C allele was associated (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.2Y5.1], P = 0.02) with increased susceptibility of CIN independent of number of sexual partners (OR, 2.2; 95% CI, 1.1Y4.6; P = 0.03) and smoking (OR, 3.3; 95% CI, 1.6Y6.6; P = 0.001). The haplotype VEGF j460C Y +405C Y +936C was associated with an OR of 5.2 (95% CI, 1.2Y52.7) for the susceptibility of CIN. Conclusions: The presence of the variant VEGF +405C allele and the haplotype VEGF j460C Y +405C Y +936C are independently associated with higher susceptibility of CIN.
