An Exciting New Era in the Treatment of Myeloproliferative Neoplasms

Myeloproliferative neoplasms (MPNs), including primary myelofibrosis and myelofibrosis (MF) evolving from a pre-existing MPN (post polycythemia vera- and post essential thrombocythemia-myelofibrosis) are clonal hematopoietic stem cell disorders with heterogeneous symptoms, mutational profile, transformation risk and prognosis. Given the potentially chronic disease course, the goal of therapy in MF is to alleviate associated signs and symptoms, including reduction in spleen size, weight gain, improved performance status, and control of constitutional symptoms, leading to a prolonged survival and reduced transformation to leukemia.
