The actual incidence of MDS in the United States is unknown. MDS was first considered a separate disease in 1976, and its occurrence was estimated at 1500 new cases every year. At that time, only patients with less than 5% blasts were considered to have this disorder. MDS was not classified as neoplastic and included in cancer registries until 2001. [7] Current estimates of the incidence of MDS in the United States vary widely, from 10,000 to 30,000-55,000 new cases each year. [7, 8, 9, 10] The higher figures have been questioned as possible overestimates resulting from inclusion of other hematopoietic conditions. [11]
