Nonrandom numerical chromosomal abnormalities (NCA) are frequent in invasive breast cancer, but little is known about such changes in microscopic precursor lesions. Mammographically detected 'suspicious' breast lesions were localized by specimen radiology of sliced breast tissue. The slices containing the lesion were imprinted onto coated slides by gentle scraping. The corresponding hematoxylin and eosin stained histologic sections and Diff- Quik stained imprints were used for classification as ductal hyperplasia (DH), atypical ductal hyperplasia (ADH), and ductal carcinoma in situ (DCIS). Additional slide imprints were evaluated for copy number of chromosomes 7, 18, and X by using fluorescent in situ hybridization with alpha satellite probes. NCA were detected in 1 of 9 (11%) cases of DH, in 2 of 8 (25%) cases of ADH, and in 14 of 16 (87%) cases of DCIS. There was selective loss (chromosome 18) in one case of DCIS; all other cases with NCA had a gain of at least one chromosome. There is a progressive increase in incidence of NCA in DH, ADH and DCIS. The majority of NCA are chromosomal gains.
