Does interferon alpha prolong survival and prevent progression in patients with PV?

During the 62nd American Society of Hematology (ASH) Annual Meeting and Exposition, the MPN Hub spoke to Ghaith Abu-Zeinah, Weill Cornell Medicine, New York, US. We asked, Does interferon alpha prolong survival and prevent progression in patients with polycythemia vera (PV)?

Does interferon alpha prolong survival and prevent progression in patients with PV?

PV is a disease associated with shorter survival due to short-term complications, such as thrombosis, and long-term complications of progression to myelofibrosis and transformation to acute leukemia, which are associated with poor prognosis. The current treatment guidelines for PV recommend phlebotomy only for low-risk patients and, for a long time, these guidelines favored hydroxyurea over interferon alfa for the initial treatment of high-risk patients.

In this podcast, Abu-Zeinah shares the key findings of a retrospective study comparing myelofibrosis-free survival and overall survival of 470 patients with PV treated with recombinant interferon alfa, hydroxyurea, or phlebotomy only.
