How Epidemiology of Polycythemia Vera Has Changed in the Last 10 Years: Results From the Whole Prospective Cohort of Patients in Cyto-PV Trial As Compared with Eclap Prospective Cohort

Abstract Abstract 1748 Introduction: Polycythemia vera (PV) is a chronic myeloproliferative neoplasms characterized by erythrocytosis, vasomotor disturbances, pruritus, risk of disease progression into acute myeloid leukemia or myelofibrosis and cardiovascular events, the last representing the main cause of morbidity and mortality. Since 2005 the V617F point mutation in Janus Kinase 2 (JAK2) gene gained a dominant role in determining the molecular basis and the diagnosis of PV. We compared the clinical epidemiology of the 1638 patients included in the ECLAP trial in the years 1997 to 2001, with that of a “modern” cohort of 365 PV, JAK2-positive patients included in the Italian CYTO-PV rando…
