ABSTRACT
The polymorphic inheritance of human drug-metabolizing enzymes, such as those encoded by the GST and CYP systems, has been implicated in both cancer risk and prognostic. In an effort to increase our understanding of the interaction between potential environmental exposure, lifestyle, and genetic factors in the predisposition and response to radiotherapy of prostate cancer patients, we examined GSTT1, GSTM1, GSTO1, GSTP1 and CYP1A1 genotypes in a Brazilian population. We studied 125 prostate cancer patients and 100 benign prostatic hyperplasia patients paired for ethnic and lifestyle characteristics. Lifetime occupational history, dietary patterns, cigarette-smoking, and other anamnestic data were obtained through interviews. Outcome was evaluated in 42 stage Subject(s)
