Association analysis of rs2275913G>A and rs763780T>C interleukin 17 polymorphisms in Chinese women with cervical cancer

We conducted a case-control study with a relatively large sample size, and investigated the association between rs2275913G>A and rs763780T>C and the risk of cervical cancer. Three hundred and six newly diagnosed patients with histologically confirmed cervical cancer and 354 cancer-free control subjects were recruited from the Forestry General Hospital between May 2011 and May 2014. The gene polymorphisms rs2275913G>A and rs763780T>C were identified using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. By unconditional logistic regression analysis, our study found that the AA genotype and the A allele of rs2275913 were associated with a higher risk of cervical cancer compared with the wild-type genotype, and the ORs (95%CIs) were 2.84 (1.57-5.23) and 1.55 (1.22-1.97), respectively. Compared with the G allele, the A allele of rs699947 was associated with a significantly increased risk of cervical cancer in subjects above 20 years and who were positive for human papillomavirus 16 (HPV-16) or HPV-18 infection. Patients with the A allele of rs2275913 had increased risk of cervical cancer, regardless of the number of births they had experiencedor their smoking habits. We suggest that rs2275913 may play a role in the etiology of cervical cancer, although further large-sample studies are needed to confirm these observations.
