Brief Summary

Classic Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs) are a family of clonal chronic hematologic malignancies that include. polycythemia vera (PV), essential thrombocythemia (ET), and primary. Myelofibrosis (MF) . The classic MPNs historically have predominantly been diagnosed in older adults, with a median age at diagnosis of 60-72 years . Adults less than 40 years of age make up a largely underrepresented and therefore less studied subset of patients constituting 2.2-6.6% of yearly MPN cases in population- based study. These estimates are lower than incidence rate among patients between 40 and 49 years of age (9.1-10%), and have remained largely unchanged over the past four decades . However, with increasing trends in MPN incidence consequent to increased diagnostic recognition, better pathobiologic understanding, and more frequent JAK2/CALR/MPL mutational testing and newly revised WHO diagnostic criteria, it is conceivable that MPNs may be diagnosed at a higher frequency, in the younger patients, over time.
