Myeloproliferative neoplasms
Myeloproliferative neoplasms
Myeloproliferative neoplasms (MPNs) are a group of hematologic disorders characterized by the clonal proliferation of one or more myeloid cell lines that are relatively mature. These are malignant neoplastic diseases of the hematopoietic system, leading to systemic dysfunction and multi-organ failure. MPNs are generally classified into four types based on the predominant proliferating cell line: Polycythemia vera (PV): Characterized by predominant proliferation of the erythroid lineage. It commonly affects individuals around 60 years of age, with a slight male predominance. Chronic myeloid leukemia (CML): Characterized by predominant proliferation of the granulocytic lineage. It primarily affects middle-aged and elderly individuals and is rare in children. Essential thrombocythemia (ET): Characterized by predominant proliferation of the megakaryocytic lineage. It mainly occurs in middle-aged individuals. Primary myelofibrosis (PMF): Characterized by predominant proliferation of fibroblastic cells. It mostly affects middle-aged and elderly individuals. As the disease progresses, some MPNs can transform into other diseases or interconvert between various subtypes. Common symptoms include fever, fatigue, weakness, hepatosplenomegaly, bleeding, anemia, and bone pain.
