Abstract
Myelodysplastic syndromes (MDS) comprise a heterogeneous group of clonal hematologic disorders. MDS is characterized by ineffective hematopoiesis, showing dysplastic features in at least one hematopoietic lineage in the bone marrow. Considering the introduction of more differentiated therapeutic options, e.g., due to demethylating agents, lenalidomide, or allogeneic stem cell transplantation for high-risk cases, valid and easily reproducible classification systems became of major importance in the care of patients with MDS. With the use of standard classification systems, e.g., formerly the French-American-British (FAB) classification (Bennett et al. 1982), the International Prognostic Scoring System (IPSS) (Greenberg et al. 1997) or the IPSS-R (Greenberg et al., 2012) the WPSS (Malcovati et al. 2007), or the new World Health Organization (WHO) proposal (Brunning et al. 2008), staging and classification of MDS are readily achieved. The IPSS or IPSS-R, respectively, is often combined with FAB or WHO morphological criteria to provide the most complete clinical picture and the most accurate prognostic assessment possible (Bennett 2005).
