Fact Sheet
Chemical Carcinogenesis Research Information System (CCRIS)

CCRIS is a toxicology data file of the National Library of Medicine's (NLM) Toxicology Data Network (TOXNET®). It is a scientifically evaluated and fully referenced data bank, developed and maintained by the National Cancer Institute (NCI). It contains over 9,000 chemical records with carcinogenicity, mutagenicity, tumor promotion, and tumor inhibition test results. Data are derived from studies cited in primary journals, current awareness tools, NCI reports, and other special sources. Test results have been reviewed by experts in carcinogenesis and mutagenesis.

Web Access/Searching

CCRIS is accessible, free of charge, via TOXNET at: http://toxnet/nlm.nih.gov

Users can search by chemical or other name, chemical name fragment, Chemical Abstracts Service Registry Number (RN), and/or subject terms. Search results can easily be viewed, printed or downloaded. Search results are displayed in relevancy ranked order. Users may select to display any combination of data from the following broad groupings:

(a) Carcinogenicity Studies
(b) Tumor Promotion Studies
(c) Mutagenicity Studies
(d) Tumor Inhibition Studies

Users can easily conduct their CCRIS search strategy against other databases: Hazardous Substances Data Bank®, Integrated Risk Information System, GENE-TOX, TOXLINE®, and ChemIDplus®.
