Genetic Variations in Inflammatory Response Genes and Their Association with the Risk of Prostate Cancer

Prostate cancer is a common cancer in men. Genetic variations in inflammatory response genes can potentially influence the risk of prostate cancer. We aimed to examine the association between PPARG Pro12Ala, NFKB1 -94 ins/del, NFKBIA -826C/T, COX-1 (50C>T), and COX-2 (-1195G>A) polymorphisms on prostate cancer risk. The genotypes of the polymorphisms were ascertained in 543 prostate cancer patients and 753 controls through PCR-RFLP and the risk association was evaluated statistically using logistic regression analysis. The NFKB1 -94 polymorphism was shown to decrease prostate cancer risk in both heterozygous and homozygous comparison models (odds ratios of 0.74 (95% CI = 0.58–0.96) () and 0.57 (95% CI = 0.42–0.78) (), resp.). An opposite finding was observed for COX-2 (-1195) polymorphism (odds ratios of 1.58 (95% CI = 1.15–2.18) () for heterozygous comparison model and 2.08 (95% CI = 1.48–2.92) () for homozygous comparison model). No association was observed for other polymorphisms. In conclusion, NFKB1 -94 ins/del and COX-2 (-1195G>A) polymorphisms may be, respectively, associated with decreased and increased prostate cancer risk in the Chinese population.
