title: [Splenic irradiation in the treatment of idiopathic myelofibrosis. Retrospective study of 14 cases].
abstract: A retrospective study was conducted on 14 patients with idiopathic myelofibrosis after splenic irradiation in order to cure the symptoms due to secondary splenomegaly. Radiation dose ranged from 700 to 2400 cGy, depending on both clinical response and hematological toxicity. Relief of symptoms was observed in all patients (100%); reduction of splenic size ranged from 30 to 70%, with more than 50% reduction in 13/16 cases. Side effects were mild neutropenia and thrombocytopenia, which did not require interruption of treatment; four patients registered a severe anemia. All the hematological side effects stopped with the suspension of treatment. This study shows the beneficial effect of radiation therapy on the symptoms connected to splenomegaly; however, the short duration of response suggests the advantage of splenic low-dose irradiation, to be periodically repeated.
