OBJECTIVE: To use a large population-based case-control study to test the association between the common genetic variant rs743572 (-34 T to C), prostate cancer risk and circulating levels of several hormones. SUBJECTS AND METHODS: A previous meta-analysis concluded that reported associations between rs743572 in the promoter of CYP17A1 and prostate cancer risk might reflect publication bias, but a few recent studies reported associations with prostate cancer risk and data suggesting that rs743572 is functional. We genotyped 824 prostate cancer cases and 737 population-based controls, and applied unconditional logistic regression to estimate the association between rs743572 and prostate cancer risk. We also used linear regression of transformed testosterone, androstanediol glucuronide, dehydroepiandrosterone sulphate, androstenedione, sex hormone-binding globulin and oestradiol (circulating levels) measured for controls, to estimate the association between these levels and rs743572. The linear models were adjusted for age and laboratory batch. RESULTS: Men with different genotypes had similar circulating levels of all the hormones measured (all P < 0.05).="" in="" the="" case-control="" comparison="" using="" unconditional="" unadjusted="" logistic="" regression,="" the="" odds="" ratios="" (95%="" confidence="" interval)="" for="" prostate="" cancer="" were="" 1.07="" (0.87-1.32)="" and="" 0.94="" (0.71-1.25)="" for="" the="" dominant="" and="" recessive="" models,="" respectively,="" and="" for="" the="" co-dominant="" model,="" 1.10="" (0.88-1.36)="" and="" 0.99="" (0.73-1.35)="" for="" carriers="" of="" one="" or="" two="" copies="" of="" the="" c="" allele,="" respectively.="" there="" was="" no="" evidence="" of="" heterogeneity="" in="" the="" odds="" ratios="" by="" tumour="" stage="" (all="" p=""> 0.3) and grade (all P > 0.3). CONCLUSION: The results of the present study are consistent with the conclusions of the previous meta-analysis, and suggest that rs743572 has no role in the risk of prostate cancer for men of Caucasian origin.
