Primary myelofibrosis (PMF) is a chronic progressive myeloproliferative disorder with a median survival (around 5.5 years) much shorter than that of other myeloproliferative disorders. Myelofibrosis, also known as agnogenic myeloid metaplasia, is a rare disease that causes progressive scarring (fibrosis) of bone marrow, leading to abnormal blood cell counts and other serious complications. Some people with the disease may not have symptoms or require immediate treatment. Prognosis in secondary myelofibrosis depends in large part on the underlying disorder. Myelofibrosis that occurs after polycythemia vera or essential thrombocythemia typically has a poor prognosis. Prognostic scoring systems have been developed which can help determine prognosis in primary myelofibrosis and in myelofibrosis preceded by polycythemia or essential thrombocythemia.

As we consider the implications of distinguishing pre‐MF as an entity separated from overt‐MF or, indeed, other MPN, one of the most relevant issues for the haematologist is how to gauge prognosis and then select management of this group of patients appropriately. 2017-11-01 Popat U, Frost A, Liu E, et al. High levels of circulating CD34 cells, dacrocytes, clonal hematopoiesis, and JAK2 mutation differentiate myelofibrosis with myeloid metaplasia from secondary myelofibrosis associated with pulmonary hypertension.

Diagnosis requires bone marrow examination and exclusion of other conditions that can cause myelofibrosis (secondary myelofibrosis).

Myelofibrosis is a disorder that is progressive, and in most cases is irreversible. The prognosis rest on the individual’s age, red and white count, and bone marrow cytogenetic results. The best prognosis is living at least 15 years with the poor prognosis being 12 to 18 months. Background. To better describe the clinical, biological, and the outcome of non-Hodgkin's lymphoma (NHL) with, at the initial presentation, bone marrow fibrosis (MF). Patients and Methods. From January 2001 to January 2007, 16 eligible patients with NHL and MF were retrieved from the Pathology Department of the University hospital of Amiens.

Prognostic scoring systems have been developed which can help determine prognosis in primary myelofibrosis and in myelofibrosis preceded by polycythemia or essential thrombocythemia. Myelofibrosis (MF) is characterized by bone marrow fibrosis, symptom burden, splenomegaly, and cytopenias. MF is a Philadelphia chromosome–negative myeloproliferative neoplasm (MPN) 1 characterized by bone marrow fibrosis, symptom burden, splenomegaly, and cytopenias. 2 MF is a disease with significant heterogeneity in natural history and symptom Myelofibrosis (MF) is an uncommon blood cancer characterized by bone marrow scarring (fibrosis), enlarged spleen (splenomegaly), potential complications and symptoms including fatigue, fever, night sweats, itchy skin, bone pain, abdominal pain or discomfort and weight loss.1MF has a poor prognosis and limited treatment options.1,2 When myelofibrosis occurs on its own, it is called primary myelofibrosis.

In a small percentage of patients, however—about 10%—PV can worsen, changing—or transforming—into myelofibrosis (my-ah-lo-fye-BRO-sis), or MF, which is another type of MPN. PV that changes into MF is referred to as post–polycythemia vera myelofibrosis (PPV-MF).

In patients with PV, the 15-year risk of evolution to myelofibrosis is estimated at 6% and the incidence is 5.1 × 1000 person-years. 3 A similar figure is reported in young patients with PV. 4 Patients with post-PV MF have a high rate of detection of the JAK2 (V617F) mutation ranging from 91% 5 to 100%. 6 Concerning the JAK2 (V617F) mutation burden, patients with post-PV MF have the highest proportion of mutant alleles in patients with chronic myeloproliferative disorders (CMDs). 6 An Prognosis Primary myelofibrosis has a median lifespain of ~5.5 years. Death is usually a consequence of bone marrow failure (haemorrhage, anaemia, or infection), transformation to acute leukaemia, portal HTN, heart failure, cachexia, or myeloid metaplasia with organ failure.

2012-03-21 · In MPNs, they are frequent in primary myelofibrosis (PMF)(34.5%) and rare in polycythemia vera (PV) or essential thrombocythemia (ET). In AML, they are found in secondary (30%) rather than in de novo cases (6.5%), and in AML with normal karyotype ASXL1 mutations are mutually exclusive with NPM1 mutations . Driver mutation-specific clinical and genomic correlates differ between primary and secondary myelofibrosis.
