Chronic myeloid leukemia (CML) is a myeloproliferative disorder whose therapy has changed dramatically since the late 1990s. With the introduction of the tyrosine kinase inhibitor (TKI) imatinib mesylate, the treatment outcomes for patients with CML have improved markedly, and hematopoietic stem-cell transplantation is no longer routinely offered as first-line therapy for most patients in chron...

Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder. Current targeted therapies designed to inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein have made a significant breakthrough in the treatment of CML patients. However, CML remains a chronic disease that a patient must manage for life. Although tyrosine kinase inhibitors (TKI) therapy has completely transforme...

The AP-1 transcription factor JunB is a transcriptional regulator of myelopoiesis. Inactivation of JunB in postnatal mice results in a myeloproliferative disorder (MPD) resembling early human chronic myelogenous leukemia (CML). Here, we show that JunB regulates the numbers of hematopoietic stem cells (HSC). JunB overexpression decreases the frequency of long-term HSC (LT-HSC), while JunB inacti...

INTRODUCTION Inversion of chromosome 9 had been widely discussed among geneticists and evolutionary biologists because of its significant impact on various hereditary disorders and in the evolution of man. The role of such inversions in human disease evolution is an area hitherto unclear. CASE PRESENTATION We present the case of a chronic myeloid leukemia (CML) patient who showed intermittent...

In the prechemotherapy era arsenic derivatives were used for treatment of chronic myelogenous leukemia, a myeloproliferative disorder characterized by the t(9;22) translocation, the Philadelphia chromosome (Ph+). In acute promyelocytic leukemia response to arsenic trioxide (As2O3) has been shown to be genetically determined by the acute promyelocytic leukemia-specific t(15;17) translocation pro...

| 1634 | haematologica | 2009; 94(12) The World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissues includes within myeloid neoplasms the category “Myelodysplastic/myeloproliferative neoplasms”. According to Vardiman et al., these are “clonal myeloid neoplasms that at the time of initial presentation have some clinical, laboratory or morphologic findings tha...

INTRODUCTION The 2008 World Health Organization classification of myeloid neoplasms includes the diagnostic category, myelodysplastic/myeloproliferative neoplasms (MDS/MPN), which encompasses those rare clonal myeloid proliferations that at initial presentation, show overlapping myeloproliferative and myelodysplastic features, making classification as either a myelodysplastic syndrome (MDS) or ...
