A Retrospective Analysis of the Impact of Treatments and Blood Counts on Survival and the Risk of Vascular Events During the Course of Polycythemia Vera

Researchers noted concerning survival and vascular complications that hydroxyurea-treated patients with polycythemia vera who needed at least one phlebotomy per year were not significantly different from hydroxyurea-treated patients with a low phlebotomy requirement. Therefore, they concluded that complementary phlebotomy in hydroxyurea-treated patients, in order to maintain hematocrit levels, is safe.
