Approximately 2% of histologically benign giant cell tumors (BGCT) of bone are complicated by lung metastases, which can progress despite their benign histologic appearance. Almost all BGCT studied by DNA flow cytometry (FCM) have been reported to be diploid. However, the very few cases with lung metastases previously analyzed were all aneuploid. To assess the usefulness of DNA FCM in predicting the metastatic potential of BGCT, seven metastasizing BGCT were studied by DNA FCM using paraffin-embedded tissue. Five were purely diploid, one was tetraploid, and one was aneuploid. The primary and the metastasis showed the same DNA distribution in all but the tetraploid case, in which the metastasis was purely diploid. A single patient, who was in the diploid group, had unresectable tumor in the lungs; she remains alive with stable disease at 30 months. The other six patients, who underwent complete resections of their lung metastases, are free of disease. These results suggest that DNA FCM is not a sensitive method for predicting the metastatic potential of BGCT since most metastasizing cases appear to be diploid.

D004273 DNA, Neoplasm DNA present in neoplastic tissue. Neoplasm DNA
D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D000782 Aneuploidy The chromosomal constitution of cells which deviate from the normal by the addition or subtraction of CHROMOSOMES, chromosome pairs, or chromosome fragments. In a normally diploid cell (DIPLOIDY) the loss of a chromosome pair is termed nullisomy (symbol: 2N-2), the loss of a single chromosome is MONOSOMY (symbol: 2N-1), the addition of a chromosome pair is tetrasomy (symbol: 2N+2), the addition of a single chromosome is TRISOMY (symbol: 2N+1).
