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. The highest number of DNA adducts was observed in the sample (+CYP) at 24 h; however, some of these DNA-adducts were also detected on control (−CYP) at 24 h. Similarly, some compounds either in oxidized form or as DNA-adducts detected in samples (+CYP) at 24 h were also present in controls (−CYP) at 72 h (e.g., m/z 734.40 and 801.43 Additional file 3 ). Estrogens can initiate cancer by reacting with DNA. Specific metabolites of endogenous estrogens, the catechol estrogen-3,4-quinones, react with DNA to form depurinating estrogen-DNA adducts.

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.

Known DNA adducts A meeting organized in Sweden at the end of 1992 attempted to summarize the world literature on DNA adducts (6).

29-55. DNA adduct assays were completed for the remaining subjects (276 with invasive breast cancer, 22 with in situ breast cancer, and 517 controls) who had donated a blood sample of adequate volume (about 25 ml) to yield sufficient DNA for the PAH analyses (100 I.g or more of DNA). To enhance the stability of our estimates for If you have been diagnosed with adenocarcinoma cancer, you have a cancer that developed in one of the glands that lines the inside of your organs. Adenocarcinoma cancers being usually in one of the following organs: prostate, breast, colon, The pancreas is an organ that releases enzymes involved with digestion, and hormones to regular blood sugar levels.
