Abstract: The 2016 revision of the World Health Organization(WHO) classification of myeloproliferative neoplasms defines 2 stages of primary myelofibrosis(PMF): the prefibrotic/early(pre-PMF) phase and the overt fibrotic(overt PMF) phase. Pre-PMF minimicks essential thrombocythemia(ET) in clinical presentation and routine laboratory examination, but shows higher rates of progression to overt-PMF, leukemic evolution and shorter overall survival comparing with ET. Thus, it is critical to distinguish pre-PMF from ET for both prognostic implications and therapeutic decisions. The current review provides an overview on how to diagnose and treat pre-PMF comparing with ET, according to clinical and laboratory parameters, bone marrow morphological changes, inflammatory status and gene mutation, with the aim of preventing the progress of the disease and improving the prognosis. -
