Detection of chromosomal aberrations in cytologic brush specimens from head and neck squamous cell carcinoma

Detection of genetic changes in the mucosa of the upper aerodigestive tract may provide a target for the screening of cytologic specimens to identify premalignant transformation in this region. In this pilot study, the feasibility of the fluorescence in situ hybridization (FISH) technique to detect genetically aberrant cells in brush specimens was evaluated.
