Previous studies examining associations suffered from limitations including the reliance on mortality data and inadequate exposure assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We conducted a nested case\u2010control study of 362 cases and 1,805 matched controls to examine the association between occupational chemical exposures and prostate cancer incidence. Workers were employed between 1950 and 1992 at a nuclear energy and rocket engine\u2010testing facility in Southern California. We obtained cancer\u2010incidence data from the California Cancer Registry and seven other state cancer registries. Data from company records were used to construct a job exposure matrix (JEM) for occupational exposures to hydrazine, trichloroethylene (TCE), polycyclic aromatic hydrocarbons (PAHs), benzene and mineral oil. Associations between chemical exposures and prostate cancer incidence were assessed in conditional logistic regression models.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>With adjustment for occupational confounders, including socioeconomic status, occupational physical activity, and exposure to the other chemicals evaluated, the odds ratio for low\/moderate TCE exposure was 1.3; 95%CI\u2009=\u20090.8 to 2.1, and for high TCE exposure was 2.1; 95%CI\u2009=\u20091.2 to 3.9. Furthermore, we noted a positive trend between increasing levels of TCE exposure and prostate cancer (<jats:italic>P<\/jats:italic>\u2010value for trend\u2009=\u20090.02).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Our results suggest that high levels of TCE exposure are associated with prostate cancer among workers in our study population.
