title: [Experiences with radioactive phosphorus therapy in cases of polycythemia vera (author's transl)].
abstract: Retrospective studies were carried out in 52 patients with polycythemia vera who were treated with radioactive phosphorus (32-P) over periods ranging between 4 and 24 years. Control of hematopoiesis was achieved in all patients. Duration of the remission induced differed considerably in the individual patients. Mean remission lasted 3-4 years. After 13 years of 32-P treatment, the mean duration of remission lengthened due to gradual transition of some cases into "spent" polycythemia. The mean annual dose of 32-P was about 2.4 mCi. In patients with long-term remissions, the dose accumulated per year was markedly less. These patients probably represent optimal preconditions for 32-P therapy. Mean survival was 12.5 years. The majority of the patients died from thorombo-embolie events or hemorrhage; incidence of acute leukemia was about 4%.
