ResumoThe TOPKAT computer-based system for predicting chemical carcinogens was evaluated by determining its ability to predict the carcinogenicity of chemicals tested by the National Toxicology Program. TOPKAT was not effective in identifying potential rodent carcinogens and noncarcinogens in the data set analyzed. The chemicals in the TOPKAT database of known carcinogens and noncarcinogens that the software identifies as most "similar" to unknown chemicals are illustrated using six examples. These "similar" chemicals generally bear no apparent relationship to the chemical of interest with regard to metabolism or potential mechanism of carcinogenicity. Environ. Mol.
