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

الملخص EN

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) (P=0.02) and 0.57 (95% CI = 0.42–0.78) (P<0.01), resp.).

An opposite finding was observed for COX-2 (-1195) polymorphism (odds ratios of 1.58 (95% CI = 1.15–2.18) (P<0.01) for heterozygous comparison model and 2.08 (95% CI = 1.48–2.92) (P<0.01) 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.
