PG - 128-32 AB - In this study, we used spectral karyotyping (SKY) and fluorescence in situ hybridization (FISH) as complementary techniques for the analysis of two therapy-related secondary myelodysplastic syndrome (t-MDS) cases with complex karyotypes, previously analyzed by G-banding. Different types of SKY's cytogenetic contributions include confirmation of G-banding results, identification of partially characterized rearrangements, identification of marker chromosomes unidentified by G-banding, and detection of cryptic reciprocal translocations. In particular, the ability of SKY to clarify a number of markers led to the comprehension of clonal evolution. The common aberration found in these two t-MDS cases was the fragility of chromosome 5 and monosomy of chromosome 18. We clearly present that the use of SKY combined with conventional G-banding analysis and FISH has assisted in the identification of important chromosomal events that may play a key role in the development of t-MDS.
