Myeloproliferative neoplasms are clonal marrow disorders with overproduction of blood cells and a risk of thrombosis and progression.
Quick Answer
Myeloproliferative neoplasms are clonal marrow disorders with overproduction of blood cells and a risk of thrombosis and progression. Dr. Sachita Baniya (NMC 20158, 8+ years of clinical experience in haematology and haemato-oncology) evaluates myeloproliferative neoplasms (mpn) at Kathmandu Neurology Clinic & Cognitive Center, 117 Lal Durbar Marg, Kathmandu, Bagmati Province 44600, Nepal — evidence-based, medically reviewed.
MPNs include polycythaemia vera, essential thrombocythaemia and primary myelofibrosis. They share JAK2, CALR or MPL mutations. Management focuses on symptom control, thrombotic risk reduction and surveillance for progression.
Diagnosis uses blood counts, marrow morphology and mutation testing. JAK2, CALR and MPL testing supports the diagnosis, and triple-negative cases require careful exclusion of other causes.
Polycythaemia vera is managed with phlebotomy, aspirin and cytoreduction. Essential thrombocythaemia treatment depends on thrombosis risk. Myelofibrosis may be treated with JAK inhibitors, supportive care and transplant in selected high-risk patients.
Management is individualized and discussed with benefits, limitations, and follow-up.
There is no proven prevention. Cardiovascular risk factor control and avoiding smoking reduce thrombosis risk.
Red flags — seek urgent care
Most MPNs are acquired, not inherited. A family history is uncommon but exists in a small proportion.
MPNs increase the risk of arterial and venous clots, especially with older age, prior thrombosis and JAK2 mutation. Risk assessment guides treatment.
Yes. MPNs can progress to myelofibrosis or acute leukemia, particularly primary myelofibrosis. Regular monitoring is important.
Aquagenic pruritus is a classic symptom of polycythaemia vera. It can improve with treatment of the underlying disease.
Aspirin reduces clot risk in some patients, but cytoreduction may be needed for high-risk disease or uncontrolled counts. Treatment is individualised.
Removing blood to lower haematocrit in polycythaemia vera. It is usually combined with aspirin and sometimes cytoreduction.
They reduce spleen size and symptoms in myelofibrosis. They do not cure the disease and require monitoring for infection and cytopenias.
Regular blood counts, clinical review, spleen assessment and monitoring for thrombosis, bleeding or progression.
Specialist assessment for abnormal blood counts, anaemia, low platelets, bleeding, clotting and suspected blood disorders.
Care for polycythaemia vera, essential thrombocythaemia and primary myelofibrosis.
Cytogenetics, FISH, PCR and next-generation sequencing for blood cancers.
Polycythaemia vera is a myeloproliferative neoplasm causing excess red cell production and an increased risk of thrombosis.
Essential thrombocythaemia is a myeloproliferative neoplasm causing persistently high platelets and a risk of thrombosis or bleeding.
Primary myelofibrosis is a myeloproliferative neoplasm with marrow fibrosis, splenomegaly and progressive cytopenias.
