ABSTRACT
OBJECTIVES:
Fas is the prototypic representative of the death receptor subgroup of the tumor necrosis factor (TNF) receptor family. Recently, single nucleotide polymorphisms (SNPs) of the Fas or Fas ligand (FasL) genes have been shown to be associated with an increased risk of several cancers and with the prognosis of several cancers. The objective of this study was to evaluate the association between the SNPs of the Fas and FasL genes and papillary thyroid cancer (PTC) and to assess the relationship between these SNPs and the clinicopathological characteristics of PTC.METHODS:
Five SNPs located within the two genes of Fas and FasL were genotyped using direct sequencing in 94 patients with PTC and 364 healthy controls. Genetic data were analyzed using commercially available software. And, the statistical analyses were performed according to clinicopathologic characteristics of PTC.RESULTS:
Genotyping analysis demonstrated that the intron SNP (rs1571013), promoter SNP (rs1800682) and 3'-UTR SNP (rs1468063) of Fas were significantly associated with the development of PTC. We also detected a significant difference between patients with PTC and healthy controls with respect to Fas gene allele frequencies. Furthermore, we found that the 3'-UTR SNP (rs1468063) of Fas was associated with the multifocality of cancer [dominant model, OR 0.28, p=0.028; log-additive model, OR 0.43, p=0.033].CONCLUSION:
We observed a significant association between SNPs of the Fas gene and the development of PTC. In addition, there was a significant association between a Fas SNP and the multifocality of PTC.Palavras-chave
