Association between the GGN tri-nucleotide repeat polymorphism in androgen receptor gene and prostate cancer risk:a systematic review and meta-analysis / 国际检验医学杂志

ABSTRACT

Objective To provide a powerful and conclusive result for the association between the GGN polymorphic repeats in androgen receptor (AR)gene and prostate cancer (PCa)risk.Methods CNKI,VIP,Wanfang,PubMed/Medline,Embase and The Cochrance Library electronic database were used to retrieve the eligible publications addressing the association between the AR gene GGN polymorphic repeats and prostate cancer risk.16 GGN polymorphism repeats were used as cut off value,meta-analysis was ap-plied to the study on the association between the length of polymorphism repeats and prostate cancer risk.Results 9 cases of con-trol studies were included in this meta-analysis and a total of 2 438 cases and 1 968 controls were included.People with ≤16 GGN polymorphism repeats displayed a higher risk of prostate cancer(OR =1.15,95%CI1.00 -1.31,P =0.04).Conclusion ≤16 GGN polymorphism repeats polymorphism associated with increased risk of prostate cancer.
