Association between single nucleotide polymorphisms of VEGF gene and pelvic lymph node metastasis in patients with early-stage cervical cancer

Cervical cancer patients in early-stage cervical cancer (ECC) were divided into pelvic lymph node (PLN) metastasis and non-PLN metastasis group. Single nucleotide polymorphism (SNP) genotyping for the VEGF gene was conducted and plasma VEGF levels were measured. Multivariate analysis was performed t...

Description
Summary:	Cervical cancer patients in early-stage cervical cancer (ECC) were divided into pelvic lymph node (PLN) metastasis and non-PLN metastasis group. Single nucleotide polymorphism (SNP) genotyping for the VEGF gene was conducted and plasma VEGF levels were measured. Multivariate analysis was performed to assess the correlation between SNPs of the VEGF gene and PLN metastasis. We found that SNP of the VEGF rs2010963 was independently associated with PLN metastasis. GG and CG genotype had increased susceptibility to PLN metastasis compared with CC genotype, and moreover, OR was higher in GG genotype than in CG genotype. Plasma VEGF levels were lowest in CC genotype, intermediate in GC genotype and highest in GG genotype. In summary, the SNP of the VEGF rs2010963 affected susceptibility to PLN metastasis in patients with ECC, and GG and CG genotype had increased susceptibility compared with CC genotype. The potential mechanism was associated with elevated plasma VEGF levels. Impact Statement What is already known on this subject? The positive expression of vascular endothelial growth factor (VEGF) is correlated with higher risk of lymph node metastasis among cervical cancer patients, and VEGF levels of patients with pelvic lymph node (PLN) metastasis are significantly higher than those without PLN metastasis. Additionally, single nucleotide polymorphisms (SNPs) of the VEGF gene have been indicated to be correlated with individual susceptibility to tumours and expression and protein production of VEGF. What do the results of this study add? The SNP of the VEGF rs2010963 was independently associated with PLN metastasis in patients with early-stage cervical cancer (ECC). The GG and CG genotype of the VEGF rs2010963 had increased susceptibility to PLN metastasis compared with CC genotype. Plasma VEGF levels were lowest in the CC genotype, intermediate in the GC genotype and highest in the GG genotype. What are the implications of these findings for clinical practice and/or further research? The SNP of the VEGF rs2010963 affected susceptibility to PLN metastasis in patients with ECC, and the potential mechanism was associated with elevated plasma VEGF levels.
