Are Patients with High-Risk Polycythemia Vera (PV) Receiving Cytoreductive Medications? A Retrospective Analysis of Real-World Data

BackgroundPatients with polycythemia vera (PV) have a higher mortality risk compared with the general population, primarily driven by cardiovascular disease, thrombotic events (TEs), and hematologic transformations. The goal of risk-adapted therapy in PV is prevention of TEs. Current treatment recommendations indicate that high-risk patients (aged ≥ 60 years and/or with history of TEs) should be managed with cytoreductive medications, phlebotomy, and low-dose aspirin. This noninterventional study was conducted to describe real-world cytoreductive medication treatment in adult patients with PV, stratified by risk, in the United States.
