[Recent findings and advances in treatment of myeloproliferative neoplasms].

Many novel agents have been developed for BCR::ABL1-negaive myeloproliferative neoplasms (MPN), namely, polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF). Some of these agents not only achieve hematologic complete response, reduce spleen size, and alleviate constitutional symptoms, but also induce molecular response, which means that they reduce the allele burden of driver gene mutations. These agents also prevent and alleviate fibrosis in bone marrow, which reduces the incidence of thrombotic events and disease progression and might improve prognosis. This article discusses the latest findings and promising treatments, including ongoing clinical trials, in PV, ET, and PMF.
