We used spectral karyotyping (SKY) and fluorescence in situhybridization(FISH)tofurthercharacterizechromosomalabnormali-ties in 35 patients with hematological disorders. SKY confirmed 149aberrations, refined 117, and detected 11 hidden changes. Eighteenabnormalities were detected only by G-banding. Ten monosomiesand two deletions described by G-banding were shown to be involvedintranslocationsorringchromosomes.TheseresultsdemonstratethatSKY increases the accuracy of karyotype interpretation, which is im-portant for proper diagnosis and management of hematological ma-lignancies. Key Words: spectral karyotyping, hematological disorders( Diagn Mol Pathol 2004:13:190–195) S ince the introduction of chromosome banding techniques,numerous recurrent aberrations have been identified in he-matological malignancies, and their detection has become es-sential for accurate diagnosis and clinical management of pa-tients. Chromosomal aberrations represent one of the most im-portant independent prognostic factors, concerning thelikelihoodofremissioninductionandriskofrelapse.Recently,some of these aberrations have been used within the WHOclassification to define specific disease subgroups.
