Abstract

PURPOSE:

Genome-wide association studies have identified several genetic variants at 8q24 that are strongly associated with prostate cancer risk in populations of European, American and Japanese ancestry. We investigated the contribution of these prostate cancer risk variants in the Chinese population.

MATERIALS AND METHODS:

We evaluated the association of 14 single nucleotide polymorphisms at 8q24 with prostate cancer risk using high resolution melting curve combined gene sequencing methods in case-control groups, including 265 cases and 288 controls. We explored the association between clinical covariates (age at diagnosis, prostate specific antigen, Gleason score and tumor stage) and risk loci in our study to infer their impact on aggressive prostate cancer.

RESULTS:

Four of the 14 single nucleotide polymorphisms were associated with prostate cancer risk, including rs16901966 (OR 1.343, 95% CI 1.029-1.754, p = 0.030), rs1447295 (OR 1.499, 95% CI 1.109-2.027, p = 0.008), rs11986220 (OR 1.589, 95% CI 1.160-2.178, p = 0.004) and rs10090154 (OR 1.571, 95% CI 1.146-2.154, p = 0.005). Haplotype based association analysis of the risk alleles revealed significant differences between cases and controls. The risk alleles of rs16901966, rs1447295, rs11986220 and rs10090154 were associated with age at diagnosis and tumor stage compared with controls while rs16901966 was associated with aggressive prostate cancer (OR 1.538, 95% CI 1.076-2.099, p = 0.018).

CONCLUSIONS:

For northern Chinese men rs16901966, rs1447295, rs11986220 and rs10090154 at 8q24 (region 1, region 2) are associated with prostate cancer and prostate cancer related clinical covariates.
