PURPOSE Recent studies have detected aberrant promoter methylation of adenomatous polyposis coli promoter 1 A (APC), cyclin-dependent kinase inhibitor-2A (p16(INK4a)), retinoic acid receptor beta2, and RAS association domain family protein 1 (RASSF1A) in bronchial aspirates and suggested their use as biomarkers for lung cancer diagnostics. The purpose of(More)
Global DNA hypomethylation is a common phenomenon in bladder cancer. Therefore we investigated whether it is possible to detect and assess global DNA hypomethylation in bladder cancer using a specific monoclonal antibody for 5-methyl-cytosine. Cytospins from exfoliative urine cytology specimens of patients with bladder cancer or a history of bladder cancer,(More)
BACKGROUND Sometimes, cytological lung cancer diagnosis is challenging because equivocal diagnoses are common. To enhance diagnostic accuracy, fluorescent in situ hybridization (FISH), DNA-image cytometry, and quantitative promoter hypermethylation analysis have been proposed as adjuncts. METHODS Bronchial washings and/or brushings or transbronchial(More)
Efficient, preferably early diagnosis of lung cancer represents a major challenge. Under this aspect the sensitivity of conventional histomorphology and cytomorphology procedures is unsatisfactory. This review highlights technical aspects, possibilities and drawbacks of the application of aberrant promoter methylation as a biomarker for lung cancer(More)
Die rasche, möglichst frühe Diagnose des Lungenkarzinoms stellt eine große Herausforderung dar. Die Sensitivität der konventionellen histo- und zytomorphologischen Verfahren ist diesbezüglich unbefriedigend. Der vorliegende Beitrag beleuchtet Technik, Chancen und Probleme des Nachweises aberranter Promotormethylierungen als Biomarker für die(More)
