Abstract
This study was to investigate the association of inflammation-related factors with the risk of lung cancer. All subjects were unrelated ethnic Han Chinese in Liaoning province. Our study conducted a hospital-based case–control study, the case group consisted of 193 histologically diagnosed lung cancer patients, and 211 controls were selected from cancer-free patients at the same. 5 single-nucleotide polymorphisms (TGFβ1 +869T/C, IL6 −634C/G, TGFβ1 −509C/T, IL1β −511C/T, and IL1α −899C/T) in inflammatory genes (IL1, IL6, TGF) were analyzed by Taqman real-time PCR method. All statistical analyses were performed with statistical product and service solutions v13.0. The genotype distribution frequency of IL6 −634C/G exists significant difference between case and control group. Individuals carrying −634GG and CG genotype had a higher risk of lung cancer. The risk allele was G in IL6 −634C/G.
