Urothelial cancer and some industry-related chemicals: an evaluation of the epidemiologic literature.
In a previous cohort study by our group, certain industry-related chemicals were judged as warranting further attention as possible urothelial carcinogens. In this paper, the epidemiologic literature of cancer of the lower urinary tract is evaluated for these substances. We would like to add combustion gases/soot from coal to the substances considered as increasing the risk of urothelial cancer. It is, however, uncertain whether this risk is due to contaminants of aromatic amines in tar volatiles or whether it depends on other agents, such as nitroarenes or polycyclic aromatic hydrocarbons. Furthermore, we find some support for the hypothesis that exposure to chlorinated aliphatic hydrocarbons increases the risk of urothelial cancer. For creosote, cutting fluids and cutting oils, hair dyes, and polychlorinated biphenyls, data are scarce. Available data do not support the hypothesis that asbestos is associated with urothelial cancer. "Publication bias," such that only limited information was available, was judged to be a potential problem in the review for many, but not all, of the substances investigated.
