Myelodysplastic Syndromes (MDS) are a collection of disorders in which blood cells remain at an immature stage within the bone marrow and never fully develop into cells capable of performing their necessary functions. MDS patients do not meet criteria for leukemia based on the percentage of blasts in the bone marrow. However, many MDS patients will eventually develop AML over time, leading to use of the terms “smoldering leukemia” and “preleukemia” to describe this condition.
Also called pre-leukemia. A group of disorders in which the bone marrow does not function normally and not enough normal blood cells are made.
Preleukemic conditions characterized by bone marrow or hematopoietic dysfunction and manifested as anemia, neutropenia, thrombocytopenia or a combination of these disorders.
