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. 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. 2 From a pathogenesis standpoint, the disease features clonal proliferation involving pluripotent 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 Myelofibrosis is a type of bone marrow cancer.
Average age at onset was 60.7 years. Men were affected 1.4 times more frequently than women. The factors associated with shorter survival included anemia the Kaplan-Feinstein comorbidity index,17 grades each comorbid disease and condition into 1 of 3 levels accord-ing to the severity of individual organ decompensation and prognostic impact: grade 1 (mild), grade 2 (moder-ate), or grade 3 (severe). For each patient, an overall comorbidity score (0 indicates none, 1 indicates mild, 2 MF-BIOLOGY, MANAGEMENT, AND CASE REPORT OF OCULAR MANIFESTATION Myelofibrosis is an uncommon myeloproliferative neoplasm, a type of blood cancer where excess red blood cells, white blood cells, or platelets are produced in the bone marrow. The rarity of this abnormality has many medical professionals struggling to understand its genetic underpinnings. This review seeks to outline the current A dynamic prognostic model to predict survival in primary myelofibrosis: a study by the IWG-MRT (International Working Group for Myeloproliferative Neoplasms Research and Treatment).
Blood 2009; 113 : 2895–2901. 2016-10-14 2012-04-20 The annual incidence of primary myelofibrosis (PMF) is about 1 case per 100,000 individuals.

The score was developed and validated by Gangat et al. There are several scoring systems used for myelofibrosis that evolved over time. The original IPSS, international prognostic scoring system, weighs mostly on clinical variables such as age of the patient, presence of constitutional symptoms, leukocytosis, anemia, and presence of circulating blasts.

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 The prognostic nutritional index (PNI) integrates information on albumin and absolute lymphocyte count (ALC) and reflects the inflammatory, nutritional and immune status of a patient.

All the statistical analyses were performed with IBM SPSS 22.0 and Stata 11.
For patients who have been diagnosed with MF, the tools can help estimate prognosis based on validated models. Purpose The Dynamic International Prognostic Scoring System (DIPSS) for primary myelofibrosis (PMF) uses five risk factors to predict survival: age older than 65 years, hemoglobin lower than 10 g/dL, leukocytes higher than 25 × 10 9 /L, circulating blasts ≥ 1%, and constitutional symptoms. We aimed to validate the MYelofibrosis SECondary to PV and ET prognostic model (MYSEC-PM) in 159 patients with myelofibrosis secondary to polycythemia vera (PV) and essential thrombocythemia (ET) from the European Society for Blood and Marrow Transplantation registry undergoing transplantation from matched siblings or unrelated donors. As the clinical understanding of myelofibrosis has evolved, a variety of prognostic systems have been developed.
