Abstract

The incidence of thyroid cancer has been on the increase in a number of countries, and certain genetic factors associated with the increased incidence of the papillary thyroid cancer (PTC) have been identified. However, little is known about the effect of mutations of the cystic fibrosis transmembrane conductance regulator (CFTR) gene, expressed in the thyroid. We hypothesized and investigated that CFTR single nucleotide polymorphisms (SNPs) may be associated with the risk and/or progression of PTC. A total of 105 PTC patients, confirmed by pathological tests, and 323 controls, without any thyroidal disease, were recruited. One promoter SNP (rs4148682) and one coding SNP (rs213950, Val470Met) in the CFTR gene were analyzed, using direct sequencing. The PTC patients were sub-grouped and compared by their clinical and pathological characteristics of PTC. The results showed that the association between SNPs in the CFTR gene and the development of PTC was statistically insignificant. However, in the clinical and pathological features, rs4148682 was found to be correlated with multifocal tumors, location and cervical node metastasis of PTC. rs231950 was also correlated with multifocal tumors, location and nodal metastasis of PTC. The G allele of rs213950 was correlated with increased risk of multifocal tumors and bilateral lobe location. However, in cervical lymph node metastasis, the A allele of rs213950 was found to reflect high risk. Our study suggests that the CFTR gene polymorphisms studied may not be associated with the development of PTC, but that rs4148682 and rs213950 may be associated with clinical features and prognosis, such as multifocality, location of cancer and cervical lymph node metastasis of PTC.
