Abstract:The identification of the JAK2V617F mutation in myeloproliferative neoplasms (MPN) paved the way for the pivotal studies that led to the FDA approval of a JAK1/2 inhibitor, ruxolitinib (rux) in patients (pts) with myelofibrosis (MF). Improvement in splenomegaly and debilitating disease-related symptoms were the primary clinical responses observed with rux. Although JAK2 mutational status did not impact response/survival in MF pts, cytogenetics had an impact on prognosis. In a related myeloid neoplasm specifica… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
