Abstract
Chromosome 13 abnormalities are frequently observed in multiple myeloma (MM ). Several reports recently demonstrated the strong prognostic value of the se abnormalities, associated with a short survival. Cytogenetic studies hav e shown that most of these abnormalities are complete monosomies. In order to define the common minimal deletion, we analysed a series of 234 patients with MM using fluorescence in situ hybridization (FISH) with a panel of fi ve probes mapping along the whole chromosome 13, A chromosome 13 abnormalit y was observed in 98 patients (42%), 90 of whom (92%) displayed a complete monosomy. In seven of the eight remaining patients presenting partial delet ions, the three probes specific for the 13q14 region were deleted, Only one patient (1%) displayed a small deletion of the D13S319 locus. In conclusio n, FISH should be used for the analysis of chromosome 13 abnormalities, usi ng probes mapping in the 13q14 region.
