Of all the chemicals classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC), 90% exert their biological effects through binding of their metabolically activated intermediates to DNA forming covalent DNA adducts. As a consequence DNA adducts are generally considered to be causative and directly related to tumour formation. DNA adduct analyses reflect tissue-specific rates of adduct formation and removal, which depend on carcinogen uptake, metabolic activation, DNA repair, adduct instability and tissue turnover and are thus useful markers of carcinogen exposure. The measurement of carcinogen-DNA adduct levels is central to the understanding of chemical carcinogenesis both in animals and humans to determine molecular mechanisms and exposure. Sensitive methods for DNA adduct analysis used to date are based on 32P-postlabelling, immunoassay, mass spectrometry and laser-induced fluorescence. The aim of this workshop held over 2 days (29-30 September 2006) at the German Cancer Research Center (DKFZ) in Heidelberg, Germany, was to discuss methodological improvements of DNA adduct detection with emphasis on the 32P-postlabelling procedure as well as new findings achieved by applying the methods to studies on understanding human cancer mechanisms and to elucidate the relationship between adduct formation and human cancer risk.

{dagger}This workshop was dedicated to Prof. Manfred Wiessler, head of the Division of Molecular Toxicology at the German Cancer Research Center, Heidelberg, Germany, on the occasion of his 65th birthday.
