In molecular genetics, a DNA adduct is a segment of DNA bound to a cancer-causing chemical. This process could be the start of a cancerous cell, or carcinogenesis. Abstract We present a meta-analysis to test the hypothesis that the presence of a high level of bulky DNA adducts in tissues is associated with an increased risk of cancer in humans. Seven articles were selected that matched the selection criteria, for a total of 691 cancer patients and 632 control subjects.

Author information: (1)Center for Nutrition and Toxicology, Karolinska Institute, Sweden. Anyone having lectured on DNA adducts is likely to be familiar with the first question after the presentation: 'What is the relationship of DNA adducts and cancer?'. Bulky DNA adducts are biomarkers of exposure to aromatic compounds and of the ability of the individual to metabolically activate carcinogens and to repair DNA damage. Their ability to predict cancer onset is uncertain. We have performed a pooled analysis of three prospective studies on cancer risk in which bulky DNA adducts have been measured DNA adducts are considered a reliable biomarker that reflects carcinogen exposure to tobacco smoke, but the central question is what is the relationship of DNA adducts and cancer? Furthermore, adducts will provide an intermediary tool for genotyping studies, both for metabolic enzyme and for DNA repair system genotypes.

It was hypothesized that, similar to the animal models, human DNA adduct formation may be necessary but not sufficient for tumor induction. In addition to being markers of carcinogen exposure, DNA adducts may directly alter regulation of transcription of tumor suppressors or oncogenes.

Bulky DNA adducts were measured by 32P-postlabelling (in the ma-jority of studies) or ELISA. Six studies measured adducts in WBCs and one (12) in normal lung tissue around tumor tissue. Six were case-control investigations, and one was a case-control study on lung cancer nested within a in the identification of DNA adducts. A vivid history of the development of ideas on chemical causes of cancer has been published by Lawley (2).

Eur J Cancer 44(5):636-640 18314326. DNA adducts formed by cisplatin [cis-diamminedichloroplatinum(II)] were measured in blood samples from 48 testicular cancer patients treated in four centers in Europe during four to six cycles with cisplatin infusions on five successive days (total samples, 112). Results Aromatic DNA adductsWhen tissue DNA was analyzed for DNA adducts derived from carcinogen exposure, a significantly higher level of aromatic DNA adducts was detected in the normal adjacent tissues obtained from patients with pancreatic cancer ( Table 1). The DNA adduct patterns are as reported in our previous study [2] and are not shown Polycyclic aromatic hydrocarbon (PAH)-DNA adducts have been associated with breast cancer in several small studies. The authors' pooled analysis included 873 cases and 941 controls from a population-based case-control study.
