Résumé
The aim of the present study was to investigate the clinical significance of 7 single nucleotide polymorphisms (SNPs) of vascular endothelial growth factor A (VEGFA), endothelin receptor type A (EDNRA), nibrin (NBS1) and Fas cell surface death receptor (FAS) genes in patients with nasopharyngeal carcinoma (NPC). Genomic DNA was extracted from the peripheral blood specimens of 60 patients. Genotyping of 4 VEGFA polymorphisms, namely VEGFA -1154 G/A (rs1570360), -2578 A/C (rs699947), -1498 C/T (rs833061) and +936 C/T (rs3025039), as well as EDNRA SNP p.His323 (rs5333), NBS1 p.E185Q (rs1805794) and FAS -671 A/G (rs1800682) was performed by using Sanger sequencing. The VEGFA +936 CC genotype was more frequent in tumors with bilateral infiltration of pterygoid plates compared to those with ipsilateral (76.9% vs. 69.6%, p=0.008) and no infiltration of pterygoid plates (76.9% vs. 68.8%, p=0.023). VEGFA -2578, VEGFA -1154 and VEGFA +936 were significantly associated with infiltration to the pterygoid processes (p=0.011, p=0.041 and p=0.032, respectively). EDNRA H323H TT genotype was marginally associated with infiltration to the ipsilateral medial pterygoid muscles (p=0.045). A trend towards longer overall survival was observed for VEGFA -2578 CC as compared to AC (HR=0.24, p=0.060). The studied VEGFA SNPs seem to be associated with the local extension of the NPC and maybe with the clinical outcome of this patient group.

BACKGROUND/AIM
OBJECTIVE
The aim of the present study was to investigate the clinical significance of 7 single nucleotide polymorphisms (SNPs) of vascular endothelial growth factor A (VEGFA), endothelin receptor type A (EDNRA), nibrin (NBS1) and Fas cell surface death receptor (FAS) genes in patients with nasopharyngeal carcinoma (NPC).
PATIENTS AND METHODS
METHODS
Genomic DNA was extracted from the peripheral blood specimens of 60 patients. Genotyping of 4 VEGFA polymorphisms, namely VEGFA -1154 G/A (rs1570360), -2578 A/C (rs699947), -1498 C/T (rs833061) and +936 C/T (rs3025039), as well as EDNRA SNP p.His323 (rs5333), NBS1 p.E185Q (rs1805794) and FAS -671 A/G (rs1800682) was performed by using Sanger sequencing.
RESULTS
RESULTS
The VEGFA +936 CC genotype was more frequent in tumors with bilateral infiltration of pterygoid plates compared to those with ipsilateral (76.9% vs. 69.6%, p=0.008) and no infiltration of pterygoid plates (76.9% vs. 68.8%, p=0.023). VEGFA -2578, VEGFA -1154 and VEGFA +936 were significantly associated with infiltration to the pterygoid processes (p=0.011, p=0.041 and p=0.032, respectively). EDNRA H323H TT genotype was marginally associated with infiltration to the ipsilateral medial pterygoid muscles (p=0.045). A trend towards longer overall survival was observed for VEGFA -2578 CC as compared to AC (HR=0.24, p=0.060).
CONCLUSION
CONCLUSIONS
The studied VEGFA SNPs seem to be associated with the local extension of the NPC and maybe with the clinical outcome of this patient group.
