Primary myelofibrosis (PMF) is myeloproliferative neoplasm whose diagnosis is based on a combination of clinical and pathology criteria. We evaluated 560 consecutive patients who were diagnosed with PMF upon a referral to our center and evaluated the frequency of and reasons for diagnostic discordance. Discordance in the diagnosis was found in 70 (12.5%) patients. Discordant cases had a significantly lower grade of bone marrow fibrosis (grade 0-1), more likely to be JAK2V617F-mutation negative, and have no peripheral blood blasts, possibly explaining the difficulty in making a proper diagnosis and underscoring the need for a complete evaluation at a tertiary center.

Lactate accumulation promotes immunosuppression and fibrotic transformation of bone marrow microenvironment in myelofibrosis.
J Transl Med
January 2025
Department of Biomedical and Biotechnological Sciences, Division of Medical Biochemistry, University of Catania, Catania, Italy.
Background: Clonal myeloproliferation and fibrotic transformation of the bone marrow (BM) are the pathogenetic events most commonly occurring in myelofibrosis (MF). There is great evidence indicating that tumor microenvironment is characterized by high lactate levels, acting not only as an energetic source, but also as a signaling molecule.
Methods: To test the involvement of lactate in MF milieu transformation, we measured its levels in MF patients' sera, eventually finding a massive accumulation of this metabolite, which we showed to promote the expansion of immunosuppressive subsets.
Fedratinib for the treatment of myelofibrosis: a critical appraisal of clinical trial and "real-world" data.

Fedratinib is a predominantly JAK2 inhibitor that has shown efficacy in untreated and ruxolitinib-exposed patients with myelofibrosis (MF). Based on randomized clinical trial data, it is approved for use in patients with International Prognostic Scoring System (IPSS) or Dynamic International Prognostic Scoring System (DIPSS) intermediate-2 or high-risk disease and is distinguished from ruxolitinib in that it can be administered without dose reduction in patients with thrombocytopenia, to a platelet count above 50,000/µL. In these trials, fedratinib achieved significant spleen volume reduction in ~30-45% of patients and improvement in total symptom scores in 35-40% with good tolerability.

Background: Myelofibrosis (MF) is a clonal haematopoietic disease, with median overall survival for patients with primary MF only 6.5 years. The most frequent gene mutation found in patients is JAK2, causing constitutive activation of the kinase and activation of downstream signalling.

N Engl J Med
January 2025
From the Department of Stem Cell Transplantation, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.
Background: Allogeneic hematopoietic stem-cell transplantation is the only curative treatment for myelofibrosis. Driver mutations are the pathophysiological hallmark of the disease, but the role of mutation clearance after transplantation is unclear.
Methods: We used highly sensitive polymerase-chain-reaction technology to analyze the dynamics of driver mutations in peripheral-blood samples from 324 patients with myelofibrosis (73% with mutations, 23% with mutations, and 4% with mutations) who were undergoing transplantation after reduced-intensity conditioning.
Warm Autoimmune Hemolytic Anemia as a Rare Presentation of Pre-fibrotic Primary Myelofibrosis.
Cureus

Hematology and Oncology, Olive View University of California Los Angeles (UCLA) Medical Center, Sylmar, USA.
Primary myelofibrosis (PMF) is an uncommon chronic myeloproliferative disorder that is commonly associated with Janus kinase 2 (JAK-2), calreticulin (CALR), or thrombopoietin receptor (MPL) mutations. Pre-fibrotic PMF (also known as pre-PMF or early PMF) is a subtype of PMF that is defined by a lower grade of fibrosis. In this report, we present a rare case of warm autoimmune hemolytic anemia (wAIHA) associated with pre-PMF.
