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. In five studies the cases had lung cancer, in one oral cancer, and in one bladder cancer. Six one oral cancer (16), and in one bladder cancer (17). Bulky DNA adducts were measured by 32P-postlabelling (in the ma-jority of studies) or ELISA.

When unrepaired, DNA adducts can cause mutations, including mutational hotspots in the p53 tumour suppressor gene and other genes, that may ultimately induce cancer formation. High DNA adduct levels have been suggested to be predictive of lung cancer risk (12), consistent with the suspected role of PAHs in lung carcinogenesis (1). Aromatic DNA adducts and breast cancer risk: a case-cohort study within the EPIC-Spain Significant interactions between maternal PAH exposure and single nucleotide polymorphisms in candidate genes on B[ a ]P–DNA adducts in a cohort of non-smoking Polish mothers and newborns 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 .

Fisetin is a senotherapeutic that extends health and lifespan

Carcinogen-DNA adducts are thought to be a useful biomarker in epidemiologic studies seeking to show that environmental exposures to xenobiotics cause cancer. This paper reviews the literature in this field from an epidemiologic perspective and identifies several common problems in the epidemiologic design and analysis of these studies.
