[Recent advances in bone marrow pathology for myeloproliferative neoplasms diagnosis].
Identification of driver genes and pathological bone marrow diagnosis were considered essential for subclassification of MPN in the revised 4th edition of the WHO classification, and this remained nearly unchanged in the 5th edition. Pathological diagnosis of primary myelofibrosis/pre-fibrotic stage by biopsy is now feasible and is becoming standardized. Progressive myelofibrosis and blast transformation are the advanced forms of MPN, and various therapeutic interventions for these forms have been devised. Observation of activated megakaryocytes on evaluation of megakaryocyte morphology could predict the progression of myelofibrosis. This paper describes recent progress in pathological diagnosis of MPN and how it is performed in practice.
