Overview & Definition
Myeloproliferative Neoplasms (MPNs) are chronic bone marrow cancers in which the marrow overproduces one or more types of blood cells (red cells, white cells, or platelets).
Types & Classification
- Polycythemia Vera (PV - High RBCs)
- Essential Thrombocythemia (ET - High Platelets)
- Primary Myelofibrosis (PMF - Marrow Scarring)
- Chronic Myelogenous Leukemia (CML)
Underlying Causes & Risk Factors
- Somatic mutations in JAK2 (V617F), CALR, or MPL genes
- Constitutive activation of tyrosine kinase signaling
Common Symptoms & Warning Signs
Diagnostic Evaluation
Accurate diagnosis requires comprehensive laboratory investigation under expert hematological supervision:
- 🔍 Complete Blood Count showing leukocytosis, erythrocytosis, or thrombocytosis
- 🔍 JAK2, CALR, and MPL Mutation Testing
- 🔍 Bone Marrow Biopsy evaluating reticulin fibrosis & megakaryocyte clusters
- 🔍 Serum Erythropoietin (EPO) & Abdominal Ultrasound
Treatment Options & Clinical Management
Under the guidance of Dr. Saikat Datta and Dr. Sachin Bansal, treatment strategies are tailored to individual clinical severity:
- 💊 Venesection (Phlebotomy) to lower hematocrit below 45%
- 💊 Cytoreductive Therapy (Hydroxyurea, Peg-Interferon Alpha)
- 💊 JAK1/JAK2 Inhibitors (Ruxolitinib / Fedratinib)
- 💊 Low-dose Aspirin antiplatelet therapy
- 💊 Allogeneic Stem Cell Transplant for Advanced Myelofibrosis
Frequently Asked Questions
Early indicators include headache, dizziness, fatigue, itching after warm bath, splenomegaly, high hemoglobin or high platelet counts on CBC.
Diagnosis involves detailed peripheral blood smear examination, specialized blood biomarker panels, and where indicated, bone marrow aspiration or genetic screening.
