In one series, median total dose per course was 9.8 Gy (range, 0.6-30.05 Gy).42  However, its benefit is transient, whereas, due to the effect on circulating progenitors,43  it involves the risk of severe and prolonged cytopenias, developing in one-third of patients.44  Therefore, I do not recommend routine use of splenic radiation; JAK inhibitors have further reduced the use of this therapy. Splenic radiation, on a fractioned basis, at a daily dose of 0.4 to 1 Gy, with weekly evaluation of spleen size and hematologic values until therapeutic effect is achieved or hematological toxicity develops, can be applied to patients that are refractory to JAK2 inhibitors and poor candidates to surgery.

Primary myelofibrosis (PMF) is a rare bone marrow blood cancer. MF is a clonal proliferation of a pluripotent hematopoietic stem cell,3  in which the abnormal cell population releases several cytokines and growth factors in the bone marrow that lead to marrow fibrosis and stroma changes and colonizes extramedullary organs such as the spleen and liver.4  Discovery of the V617F mutation of the Janus kinase (JAK)2 gene in 60% of patients with PMF or post-ET MF and 95% of those with post-PV MF represented an important step in the understanding of the pathogenesis of MF.5-7  Mutations in the thrombopoietin receptor gene (MPL) were subsequently found in 3% to 8% of patients with PMF and post-ET MF,8  whereas mutations in the calreticulin gene (CALR) have been observed in half of patients with PMF and post-ET MF lacking JAK2 and MPL mutations.9,10  Mutations shared by other myeloid neoplasms are found in some patients.11  However, the genetic trigger of MF is unknown. They can be considered as a warning, recommending the patient’s closer monitoring to detect early changes indicating the need for a different therapeutic strategy.

Status and perspectives. However, recent data in this setting indicate that, although the IPSS would be useful to identify high-risk patients, it would not accurately discriminate between the other risk categories.67  The lack of prognostic significance of some of the IPSS variables (notably, the leukocyte count) in these patients might be ascribed to the effect of the cytoreductive therapy that many were receiving for ET or PV at time of myelofibrotic transformation.
