Abstract  Chronic myelogenous leukemia, BCR-ABL1+ (CML) is a myeloproliferative neoplasm defined by the presence of the BCR-ABL fusion gene and a t(9;22)(q34;q11) cytogenetic abnormality. Its natural history is that of inexorable progression to an acute
leukemia (blast crisis) after a prolonged chronic phase. The recent development of imatinib and other inhibitors of BCR-ABL tyrosine kinase activity has dramatically altered the clinical course of CML, with long-term remissions in most patients
treated early in the course of the disease. Monitoring of resistance to therapy and progression on therapy are critical in
the current management of the disease. Problems facing the diagnostic pathologist in this “Age of Imatinib” include accurate
diagnosis and determination of CML …
