Genetic associations of visfatin polymorphisms with clinicopathologic characteristics of prostate cancer in Taiwanese males

The most general cancer in men is prostate cancer (PCa), with its risk increasing due to age and obesity. Visfatin, a member of adipokines, is related to cancer progression and metastasis, but its relationship in PCa remains undetermined. In addition, no knowledge is available regarding relations between visfatin polymorphisms and clinicopathological characteristics in PCa. We sought to investigate the functions of four visfatin gene polymorphisms and clinicopathological characteristics on the hazard of developing PCa in 695 Taiwanese males with PCa. Carriers of the GA+AA heterozygote of SNP rs61330082 were at a markedly higher risk of biochemical recurrence than those with the GG genotype. Visfatin rs61330082 and rs11977021 were related with a high risk of perineural invasion, lymphovascular invasion, and biochemical recurrence in prostate-specific antigen (PSA) > 10 PCa patients. The Cancer Genome Atlas database noted that visfatin mRNA level did not prominently differ with pathological T/N stage and overall survival. This finding is the first to document a connection between visfatin polymorphisms and clinicopathological characteristics of PCa in Taiwanese males.
