Y1 - 2017 N1 - T2 - Williams Manual of Hematology, 9e AB - BCR-ABL1–positive chronic myelogenous leukemia (CML) results from a somatic mutation in a pluripotential lymphohematopoietic cell, yielding a fusion oncogene (BCR-ABL1).CML is characterized by granulocytic leukocytosis, granulocytic immaturity, basophilia, anemia, and often thrombocytosis in the blood, intense leukemic granulocytic precursor expansion in the marrow, and splenomegaly.The natural history of the disease is to evolve into an accelerated phase in which cytopenias develop and response to chronic phase therapy is lost; either the chronic or accelerated phase can undergo further clonal evolution to acute leukemia.This natural history has been modified significantly by the introduction of inhibitors of the constitutive kinase activity of the BCR-ABL1 oncoprotein.
