Primary myelofibrosis is a myeloproliferative neoplasm in which there is the replacement of bone marrow with collagenous connective tissue and progressive fibrosis. It is characterized by: extramedullary hematopoiesis progressive splenomegaly anemia variable change in the number of granulocytes and platelets including thrombocytopenia Epidemiology Response was independent of the JAK2 mutational status, without differences between PMF and post-ET/PV MF.
