It has been suggested that there might be differences in susceptibility due to genetic polymorphisms in biotransformation enzyme genes.

The estimate relative risks (OR) were higher for individuals carrying combined CYP1A1 and GSTM1 rare genotypes, in relation to individuals carrying CYP1A1 or GSTM1 alone. Multivariate logistic regression analysis including confounding factors (age, digital examination, and PSA antigen) showed even higher risk for individuals carrying m2m2 genotype (OR\u2009=\u20093.99; 95% CI, 1.27\u201312.54), GST(\u2212\/\u2212) genotype (OR\u2009=\u20092.75; 95% CI, 1.31\u20135.79), and m2m2\/GST(\u2212) genotype (OR\u2009=\u200916.63; 95% CI, 1.67\u2013165.48).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Taken together, these findings suggest that Chilean people carrying single or combined GSTM1 and CYP1A1 polymorphisms are more susceptible to prostate cancer.
