Abstract: Non-small-cell lung cancer (NSCLC) has a multifactorial pathogenesis, and the genetic background may be one of the critical etiologic factors. Interleukin (IL)-27, a novel member of the IL-12 family, plays a vital role in antitumor immunity. The aim of the current study was to determine the association of a single nucleotide polymorphism of the IL-27 gene with the risk of NSCLC. The genotype of the IL-27 rs153109 polymorphism was analyzed in 388 patients with NSCLC and 390 healthy controls by using polymerase chain reaction-restriction fragment length polymorphism and DNA sequencing methods. In the patients with NSCLC, the frequencies of the GG, GA, and AA genotypes and the G and A alleles were 14.0%, 56.4%, 29.6%, 42.1%, and 57.9%, respectively. There were no significant differences in the genotype and allele distributions of the IL-27 rs153109 polymorphism between the patients with NSCLC and healthy controls (P>0.05). Furthermore, no association was determined between this polymorphism and different clinical characteristics in patients with NSCLC. Taken together, these findings suggest that the IL-27 gene may not be involved in the development of NSCLC in the Chinese population.
