New molecular data is incorporated into some of the changes in the classification of myeloid neoplasms. Changes were made to existing categories, and a new category known as Myeloid Neoplasms with Germline Predisposition was added.
Among the many changes:
- Myelodysplastic/Myeloproliferative Neoplasms with Ringed Sideroblasts and Thrombocytosis (MDS/MPN-RS-T) was added.
- New mutations were incorporated into the Myeloproliferative Neoplasms (MPN)
- The Myelodysplastic Syndromes (MDS) were renamed, and new diagnostic criteria were incorporated into some of the categories; the term Refractory Anemia is no longer used, but rather MDS with the various descriptions of blasts and cytopenias
