Prefibrotic primary myelofibrosis (Pre-PMF) is a rare blood cancer, classified by the World Health Organization as a distinct type of myeloproliferative neoplasm in 2016. The disease is progressive to overt primary myelofibrosis, though the rate of progression is variable and not all patients progress.Symptoms and presentation can mimic essential thrombocythemia, with the main …

Prognostic risk factors for post-essential thrombocythemia myelofibrosis and leukemia Disease duration was significantly longer in patients who progressed to develop post-ET myelofibrosis (p<0.001) and leukemia (<0.001) than in those whop did not. A progression to myelofibrosis occurred in 17 (2.8%) of the 605 patients at a median follow-up of 9.1

23 The IPSS for PMF was designed for use at time of initial diagnosis and applies five independent predictors of inferior survival: age > 65 years, hemoglobin <10 g/dL, leukocyte count >25 × 10 9 /L, circulating blasts ≥1% and presence of constitutional Raajit K. Rampal, MD, PhD, hematologic oncologist, Memorial Sloan Kettering Cancer Center, reviewed the prognostic tools used to find indicators of response to treatment in patients with myelofibrosis, during a Targeted Oncology Case-Based Peer Perspective Roundtable discussion. In the last decade 3 clinical-derived prognostic models have been developed in patients with primary myelofibrosis [1-3]. Prognostication in myeloproliferative neoplasms, however, is moving toward integrated clinical-molecular models [4,5]. Therefore, more recently another prognostic system has been developed and validated by the MYSEC project (MYelofibrosis SECondary to PV and ET Cases of the prefibrotic form of MF were not considered. Comparison of the relative power of each prognostic model to discriminate levels of risk was estimated by means of the Harrell’s concordance index (C-index) and the R 2 explained variation. All the statistical analyses were performed with IBM SPSS 22.0 and Stata 11.

Because myelofibrosis has a heterogeneous presentation, determining a patient’s prognosis can be difficult. 2 However, progress in understanding the clinical variables associated with MF has led to the development of several prognostic scoring systems. 2,3. Prognosis based on risk factors at diagnosis Treatment (IWG-MR T) of a new prognostic index for patients with primary myeloﬁbrosis. 1 This system, based on 5 adverse character- istics, identiﬁed 4 prognostic subgroups.

2 From a pathogenesis standpoint, the disease features clonal proliferation involving pluripotent The DIPSS was proposed and validated by Passamonti et al to estimate prognosis in myelofibrosis. The DIPSS plus score further refines the prior prognostic scoring system with the addition of DIPSS-independent risk factors, including karyotype, transfusion dependency and platelet count.

The 8 adverse prognostic factors included in DIPSS Plus risk model are. Age >65 years -1 POINT. Constitutional symptoms -Constitutional symptoms are defined as: Weight loss >10% of baseline in the year preceding diagnosis and/or unexplained fever or excessive sweats persisting for more than 1 month – 1 POINT. Hemoglobin <10 g/dL – 1 POINT.

Blood 2009; 113:2895. Myelofibrosis (MF) is a myeloproliferative neoplasm (MPN) often “driven” by mutations in Janus kinase 2 (JAK2), calreticulin (CALR), or the thrombopoietin receptor (MPL) [1-3].

2016-10-14 2012-04-20 The annual incidence of primary myelofibrosis (PMF) is about 1 case per 100,000 individuals. Prognosis in PMF relies on clinical patient data, karyotyping and genetic mutations. The first prototype for prognosis scoring was the international prognostic scoring system (IPSS). Primary myelofibrosis (PMF) 1 is classified as a chronic myeloproliferative disorder and characterized by variable degrees of cytopenia(s) and/or cytosis, a leukoerythroblastic blood picture, bone marrow fibrosis, and extramedullary hematopoiesis often resulting in hepatosplenomegaly.

Molecular-based scores are being developed. MF remains an incurable disease.
