PURPOSE OF REVIEW The classic BCR-ABL negative myeloproliferative disorders are at a crossroads of rapidly evolving pathogenetic understanding, leading to changes in diagnostic criteria and potentially targeted therapy. This review focuses on the implications of these changes relative to current standards. RECENT FINDINGS The V617F activating mutation of Janus kinase 2, and associated paralle...

Background Myeloproliferative disorders are a group of diseases characterized by increased proliferation of myeloid lineage. In addition to JAK2V617F mutation, several mutations in the c-MPL gene were described in patients with Philadelphia-negative chronic myeloproliferative disorders that could be important in the pathogenesis of diseases. The aim of present study was to investigate the fre...

Myeloproliferative Neoplasm (MPN) are a clonal disorder in hematopoietic stem cells (HSC). MPN is categorized to 8 subclasses, including chronic myeloid leukemia (CML), polycythemia vera (PV), essential thrombocytopenia (ET), primary myelofibrosis (PMF), systematic mastositosis (SM), chronic eosinophilic leukemia (CEL), chronic neutrophilic leukemia (CNL), and unclassified myelofibrosis disorde...
