Abstract

V originále

Accurate prognostic evaluation of patients with multiple myeloma (MM) is required for their stratification for more adequate therapy. Chromosomal G-banding and interphase fluorescence in situ hybridization (FISH) on cell-nonspecific samples and on myeloma cells selected by magnetic-activated cell separation (MACS) were used to study 13 samples from 12 multiple myeloma (MM) patients. Bone marrow (BM) samples were analysed using three approaches. Standard mitotic samples were prepared and analysed after G-banding. Interphase FISH was performed to detect the 13q14 deletion in unselected BM cells. In parallel, myeloma cells were selected from the BM using the CD138-specific antibody. The high-purity myeloma cell suspension was then analysed by interphase FISH for the 13q14 deletion. Magnetic separation yielded enriched myeloma cell suspensions with the mean viability of 98.0% (range: 97.0%-99.0%), and the purity of 97.6% (range: 87.2%-99.2%) as detected morphologically, and 85.2% (range: 44.8%-98.4%) as detected by immunophenotyping for CD138+ cells. Interphase FISH revealed the 13q14.3 deletion in 5 of 13 (38.5%) of cell-nonspecific samples and in 9 of 13 (69.2%) of enriched myeloma cell suspensions. In conclusion, interphase FISH on immunomagnetically selected MM cells increases the detection of the 13q14 deletion in BM samples from the patients with MM.
