Abstract:
Objective To investigate the possible association between the CCND1 A870G polymorphism and susceptibility to prostate cancer(PCa)in a Chinese population.Methods The CCND1 A870G genotypes were determined by TaqMan assays in 245 PCa cases and age-matched 245 controis.Odds ratios(OR)for PCa and 95%confidence intervals(CI)from unconditional logistic regression models were used to evaluate relative risks.Age,a potential PCa risk factor,was included in the logistic regression models as a covariate in the multivariate analyses on genotype and PCa risk.Results The frequencies for G and A alleles were 0.476,0.524 in PCa cases,and 0.408 and 0.592 in controls,respectively.The G allele was marginally significantly associated with the presence of PCa (P=0.054)and had an increased risk for PCa(OR=1.31,95%CI=1.00-1.72)as compared to theA allele.Compared to AA homozygote,AG heterozygote had a 1.43-fold increased risk(95%CI=0.89-2.31,P=0.142),whereas GG homozygote had a significantly higher 2.02-fold increased risk (95%CI=1.07-3.80,P=0.029)of PCa(Armitage's trend test,P=0.029).The G allele(AG or GG genotype)was more frequently found in PCa patients with metastasis than those without metastasis(P=0.014).Conclusion The G allele of CCND1 A870G is associated with the presence of PCa and GG homozygote is potentially one of the genetic risk factors for PCa in Chinese population.The G allele may be associated with the progression of PCa metastasis.
