Abstract
Since the discovery of the JAK2V617F, MPL gene, and Calreticulin gene mutations, remarkable changes have occurred in the identification of the pathology of Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs). The diagnostic criteria of polycythemia vera, essential thrombocythemia, and primary myelofibrosis in the world health organization classification systems have also been amended to include these driver gene mutations. Additionally, treatment algorithms for each disease have been reviewed. Following these changes, real world data form several countries based on national surveys have been reported. In Japan, the Japanese Society of Hematology has conducted a prospective study, named the JSH-MPN-15 study, to investigate the overall survival and risk factors of patients with MPNs. Furthermore, the retrospective JSH-MPN-R18 study was conducted and the results have been coming out. In this lecture, the results of these studies will be discussed.
