PG - 395-410 AB - Myelodysplastic syndromes (MDS) are a group of heterogeneous stem cell disorders with different clinical behaviors and outcomes. Conventional cytogenetics (CC) studies have demonstrated that the majority of MDS patients harbor clonal chromosome defects. The probability of discovering a chromosomal abnormality has been increased by fluorescence in situ hybridization (FISH), which has revealed that about 15% of patients with a normal chromosome pattern on CC may instead present cryptic defects. Cytogenetic abnormalities, except for the interstitial long-arm deletion of chromosome 5 (5q-), are not specific for any French-American-British (FAB)/World Health Organization (WHO) MDS subtypes, demonstrate the clonality of the disease, and identify peculiar morphological entities, thus confirming clinical diagnosis. In addition, chromosome abnormalities are independent prognostic factors predicting overall survival and the likelihood of progression in acute myeloid leukemia.
