Pathogenesis and Targeted Treatment Progress of Splenomegaly in Primary Myelofibrosis
Primary myelofibrosis(PMF)is a myeloproliferative neoplasm with splenomegaly as the major clinical manifestation,which is commonly considered to be linked to splenic extramedullary hematopoiesis.Alteration of CXCL12/CXCR4 pathway can lead to the migration of hematopoietic stem cells and hematopoietic progenitor cells from bone marrow to spleen which results in splenic extramedullary hematopoiesis.In addition,low GATA1 expression and the abnormal secretion of cytokines were found to be significantly associated with splenomegaly.With the application of JAK1/2 inhibitors in clinical,the symptoms of splenomegaly have been significantly improved in PMF patients.This article will review the pathogenesis and targeted treatment progress of splenomegaly in PMF.
