Purpose: To determine the association of prostate-specific antigen (PSA) 158A/G polymorphism with clinicopathologic characteristics of the disease and prostate cancer (PCa) risk.
Materials and Methods: Two hundred and six subjects, including 95 patients with PCa and 111 subjects with benign prostatic hyperplasia (BPH), were recruited in this study. Genotyping was performed by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism method.
Results: Presence of GG genotype significantly increased the risk of PCa more than 2-fold compared to AG genotype (adjusted odds ratio = 2.4; P = .03). The percentages of G alleles of polymorphisms in patients with PCa were more than that in ones with BPH (odds ratio = 1.2; P = .7).
Conclusions: The GG genotype of PSA 158A/G polymorphism is a predisposing factor for PCa. But no association was observed between alleles and grade, stage, or age of diagnosis. Similarly, the rs266882 polymorphism was not associated with PSA plasma levels.
