Polycythemia vera4

• These mutations are not specific to myelofibrosis, but are observed in other myeloproliferative neoplasms, specifically polycythemia vera and essential thrombocythemia. (wikipedia.org)
• The MPN Research Foundation has a single goal: to stimulate original research in pursuit of new treatments - and eventually a cure - for polycythemia vera,essential thrombocythemia and myelofibrosis, known collectively as myeloproliferative neoplasms (MPNs). (mpnfoundation.org)
• The classic myeloproliferative neoplasms, including chronic myelogenous leukemia (CML), polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF), are a phenotypically diverse category of malignancies that are derived from stem cells in the myeloid lineage. (mhmedical.com)
• When he was in Boston, Dr. Gardner himself had worked with Dr. William Dameshek, a great hematologist who is widely credited today with developing the concept of what was then called "myeloproliferative disorders" ("MPD"), presciently recognizing the interrelatedness of polycythemia vera, essential thrombocythemia, and myelofibrosis and their clonal origin in a classic paper in BLOOD in 1951. (mpnresearchfoundation.org)

MPNs4

• 2008: Myeloproliferative disorders are reclassified as myeloproliferative neoplasms (MPNs) by the World Health Organization and nested within the blood cancer category. (mpnfoundation.org)
• The 2008 World Health Organization (WHO) classification system considers five broad categories of myeloid malignancies: acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPNs), MDS/MPN overlap, and molecularly characterized MPN with eosinophilia 1 ( Table 78-1 ). (mhmedical.com)
• F rom the outset , we recognized that outstanding care of MPN patients required not just hematologists (who would be their primary doctors) but also the participation of other specialists who had expertise in the complications of MPNs, such as cardiologists, neurologists, vascular surgeons, interventional radiologists, dermatologists, infectious disease specialists, gastroenterologists, and rheumatologists. (mpnresearchfoundation.org)
• In honor of MPN Awareness Day 2023, MPNRF spoke with a pioneer in the research and treatment of MPNs, Andrew I. Schafer, MD, director of the Richard T. Silver, M.D. Myeloproliferative Neoplasm Center at Weill Cornell Medicine in New York City. (mpnresearchfoundation.org)

Bone marrow4

• It is classified by the World Health Organization (WHO) as a type of myeloproliferative neoplasm, a group of cancers in which there is activation and growth of mutated cells in the bone marrow. (wikipedia.org)
• It is one of the myeloproliferative disorders, diseases of the bone marrow in which excess cells are produced at some stage. (wikipedia.org)
• The blood and bone marrow morphology are essential in diagnosis, for WHO classification, establishing a baseline, monitoring response to treatment and identifying changes that may indicate disease progression. (bvsalud.org)
• 1999: The first clinical trial for myeloproliferative disorders, "Combination Chemotherapy Plus Bone Marrow or Peripheral Stem Cell Transplantation in Treating Patients With Myeloproliferative Disorders" is initiated. (mpnfoundation.org)

Disorders1

• MPN research has come a long way since 1951 when William Dameshek first described the concept of myeloproliferative disorders. (mpnfoundation.org)

Myelofibrosis1

• The Philadelphia-negative MPN that will be described are polycythaemia vera (PV), essential thrombocythaemia (ET), pre-fibrotic myelofibrosis and primary myelofibrosis (PMF). (bvsalud.org)

Malignancies2

• Myeloproliferative neoplasms (MPN) are a group of clonal haematological malignancies first described by Dameshek in 1957. (bvsalud.org)
• He has dedicated his 40-year long career to the study of the pathogenesis of B cell malignancies, including B Cell Lymphoma and Chronic Lymphocytic Leukemia, and contributed significantly to the understanding of the genetics and biology of these diseases, as quoted in major textbooks of medicine and oncology. (lls.org)

JAK22

• JAK2 is the first known genetic mutation associated with myeloproliferative diseases. (mpnfoundation.org)
• Recently, activating mutations in JAK2 and MPL have been found in the majority of BCR-ABL -negative myeloproliferative neoplasms. (mhmedical.com)

Genetic1

• The first genetic alteration recognized as a cause of myeloproliferative disease was the translocation that creates the BCR-ABL gene fusion. (mhmedical.com)

Patients2

• When we came across patients with atypical presentations of their diseases, he pushed me to come up with a hypothesis of what could be the basic problem. (mpnresearchfoundation.org)
• The LLS mission: Cure leukemia, lymphoma, Hodgkin disease and myeloma, and improve the quality of life of patients and their families. (lls.org)

Polycythemia vera and essential thrombocythemia1

• These mutations are not specific to myelofibrosis, but are observed in other myeloproliferative neoplasms, specifically polycythemia vera and essential thrombocythemia. (wikipedia.org)

Group2

• It is classified by the World Health Organization (WHO) as a type of myeloproliferative neoplasm, a group of cancers in which there is activation and growth of mutated cells in the bone marrow. (wikipedia.org)
• Myeloproliferative neoplasms (MPN) are a group of clonal haematological malignancies first described by Dameshek in 1957. (nih.gov)
