Abstract: Myelofibrosis (MF) is the most aggressive of the classic Philadelphia chromosome–negative myeloproliferative neoplasms (MPNs). In some patients with essential thrombocytopenia or polycythemia vera, which are relatively benign MPNs, MF develops as a natural evolution of their disease, resulting in post–essential thrombocythemia myelofibrosis (PET-MF) or post–polycythemia vera

Myelofibrosis is a type of blood disorder called a myeloproliferative neoplasm. These are conditions that cause an increase in the number of blood cells. The World Health Organisation (WHO) classes all myeloproliferative neoplasms as blood cancers. This is because the bone marrow is producing blood cells in an uncontrolled way.

Secondary myelofibrosis prognosis

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. If it occurs as the result of a separate disease, it is known as secondary myelofibrosis (e.g. scar tissue in the bone marrow as a complication of an autoimmune disease).

Despite advances in treatment the majority of patients eventually die from this MPNs can progress to secondary myelofibrosis or acute myeloid leukemia

Nearly all patients with secondary myelofibrosis showed mutations in JAK2 (75%), CALR (19%), or MPL (5%), and only 1% had TN status. Median OS for patients with secondary myelofibrosis was 81.8 months with mutated JAK2, 20.4 months with mutated MPL, and 161 months with mutated CALR. Myelofibrosis has the worst prognosis of the 3 diseases, as it has a median survival of less than 3 years but younger patients (<55 years) have survivals of more than 10 years.

The myelofibrosis occurring, in this case, is the natural fibrotic phase of another disease which leads to myelofibrosis. PMF differs from post-PV or post-ET secondary myelofibrosis (SMF), which has an evolution rate of ∼10% after 10 years of follow-up. 1 The course of myelofibrosis is associated with progressive constitutional symptoms (eg, fatigue, night sweats, and fever), increasing splenomegaly, worsening cytopenia, and a risk of transformation to acute myeloid leukemia (AML).

Approximately <20% patients survive for 10 years. A simple scoring system uses two risk factors, which include hemoglobin (<10 g/dl) and leukocyte count (<4000/ul or >30,000/ul). MF is associated with progressive constitutional symptoms, increasing splenomegaly, and worsening cytopenias. PV or ET may progress to a myelofibrotic stage 29 and MF itself can transform to secondary acute myelogenous leukemia. 30 Leukemic transformation occurs in 8% to 23% of patients with MF during the first decade after diagnosis.

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).

Secondary Myelofibrosis. Secondary myelofibrosis is a type of myelofibrosis (MF) and myeloproliferative neoplasm (MPN) that develops in people who have other MPNs such as polycythemia vera (PV) or essential thrombocythemia (ET) first. MF that develops on its own in people who have not been diagnosed with other MPNs is called primary myelofibrosis (PMF).

MF may also be the natural progression of a different et al.
