Leroy Satchel Paige was the longtime Negro League star who eventually received his due in the majors. He reportedly got his nickname working as a baggage porter in Mobile, Ala., where he became a satchel tree by carrying several bags at once. Satchel, the man, was literally ageless.
The diagnosis of AML requires the identification of 20% or more leukemic blasts in the bone marrow. Further analysis then must separate AML from acute lymphoblastic leukemia by showing evidence for commitment to the myeloid lineage.
In all the four disease groups, most patients had a higher blast percentage in BM than in PB. However, 341 (26%) of the 1314 patients with AML, 58 (13%) of the 446 patients with MDS, 35 (9%) of the 385 patients with ALL, and 2 (3%) of the 58 patients with CMML had a higher blast percentage in PB than in BM.
