Major criteria remain JAK2 positivity and increased red cell volume, but Cr-51 RCM is mandatory for patients who do not meet the defined elevated hemoglobin or hematocrit value (>18.5 g/dL and 60% in men and >16.5 g/dL and 56% in women, respectively). Symptoms can develop when too many red blood cells and platelets build up in the blood. The ECLAP (European Collaboration on Low-Dose Aspirin in Polycythemia Vera) trial was the first randomized study to assess prospectively the efficacy of low-dose aspirin in reducing thrombotic events in patients with PV.32 The results of this pivotal trial led to the use of prophylactic low-dose aspirin in all patients with PV and no contraindications. 2014;99(4):e55-e57. In this therapy, your doctor removes blood from your vein. 2013;122(11):1881-1886. Taken together, results from the RESPONSE and RESPONSE-2 trials indicate that ruxolitinib is the standard of care for second-line therapy in a patient population previously treated with hydroxyurea. The management of PV has changed since the discovery of the JAK2 mutation. Polycythemia vera may not cause any signs or symptoms in its early stages. Am J Hematol. 2008;130(3):336-342. Blood. The prognostic information derived from a bone marrow biopsy performed at diagnosis may translate in a more careful follow-up strategy and may be an additional reason to undertake such an analysis beyond strictly adherence to the WHO diagnostic criteria, especially in younger male patients with hemoglobin values above 18.5 g/dL or female patients with hemoglobin values above 16.5 g/dL. Criteria for diagnosis of polycythemia vera (Polycythemia Vera Study Group)' ... of thrombosis, phlebotomy alone may be appropriate . Geyer H, Scherber R, Kosiorek H, et al. Barbui T, Carobbio A, Rumi E, et al. Tang G, Hidalgo Lopez JE, Wang SA, et al. It is sug-gested that hematocrit levels should be maintained at < 50%.6,7 Patient Management and Monitoring Serum ferritin is the most reliable method of monitoring patients who are receiving therapeutic phlebotomy. However, phlebotomy still has an important role in the treatment of three conditions: polycythemia vera (PV), hereditary hemochromatosis (iron overload disorder), and porphyria cutenea tarda (PCT). It should be noted that the patients included in this analysis had a WHO-defined diagnosis of PV and were not individuals undergoing diagnostic screening. Major criteria. 61.

Major criteria. 2. 2016;35:e324-e335. Overall hematologic response was excellent (95%), although 24% of patients discontinued pegylated interferon because of toxicity. A progressive increase in the leukocyte count is considered a criterion to initiate cytoreductive treatment, and actionable cardiovascular risk factors should be managed to ameliorate the patient’s risk profile.33,53,54 Thrombocytosis (platelet count >1000 × 109/L) constitutes a risk factor. It's a lot like donating blood. Blood. 2017. Haematologica. On the other hand, the concept of second-line therapy in PV is not so clear. 57.

Your doctor will decide how often you need phlebotomy. Disease Overview: Polycythemia vera (PV) and essential thrombocythemia (ET) are myeloproliferative neoplasms respectively characterized by erythrocytosis and thrombocytosis; other disease features include leukocytosis, splenomegaly, thrombosis, bleeding, microcirculatory symptoms, pruritus, and risk of leukemic or fibrotic transformation. Pegylated interferon-alfa-2a induces complete hematologic and molecular responses with low toxicity in polycythemia vera. Passamonti F, Pietra D, Rumi E, et al. A complete hematologic remission was achieved in 24% of the patients in the ruxolitinib group and 9% of those in the standard therapy group. A dynamic prognostic model to predict survival in post-polycythemia vera myelofibrosis. In RESPONSE-2, hematocrit control was achieved in 62% of the ruxolitinib-treated patients and 19% of those receiving best available therapy. Diagnostic impact of the 2016 revised who criteria for polycythemia vera. Br J Haematol. The primary composite endpoint included hematocrit control (phlebotomy independence from week 8 to week 32, with ≤1 phlebotomy after randomization) in the absence of phlebotomy and 35% reduction in spleen volume at week 32 (the latter absent in RESPONSE-2).

A unified definition of clinical resistance and intolerance to hydroxycarbamide in polycythaemia vera and primary myelofibrosis: results of a European LeukemiaNet (ELN) consensus process. A reduction in spleen volume of at least 35% occurred in 38% of the patients treated with ruxolitinib and 1% of those who received standard therapy. doi:10.1080/10428194.2017.1300892. However, additional risk factors for thrombosis, such as leukocytosis and cardiovascular risk factors, need to be considered in the treatment algorithm of patients with PV. These modifications derive from retrospective studies recognizing the existence of patients with a Janus kinase 2 (JAK2) V617F–mutated MPN, which most often is diagnosed as ET but has PV-consistent bone marrow features, hemoglobin levels below 18.5 g/dL in males and 16.5 g/dL in females, an increased risk for thrombotic complications during follow-up, and a worse disease evolution.15-21 Such patients are defined as having “masked” or “prodromic” PV.20. 15. However, phlebotomy still has an important role in the treatment of three conditions: polycythemia vera (PV), hereditary hemochromatosis (iron overload disorder), and porphyria cutenea tarda (PCT). It can be due to an increase in the number of red blood cells ("absolute polycythemia") or to a decrease in the volume of plasma ("relative polycythemia… Björkholm M, Derolf AR, Hultcrantz M, et al. 1 DOWNLOAD DIAGNOSTIC CRITERIA Passamonti F, Cervantes F, Vannucchi AM, et al. 2015;141(12):2131-2138. Characteristics and clinical significance of cytogenetic abnormalities in polycythemia vera [published online May 4, 2017]. A multicenter, retrospective, observational study conducted in a cohort of 1545 patients with PV (diagnosed according to the 2008 WHO criteria) focused on the evaluation of survival patterns.37 In multivariable analysis, survival was negatively affected by older age, leukocytosis, venous thrombosis, and abnormal karyotype; a prognostic model that included the first 3 factors (with older age bearing significant weight) identified risk groups with median survival times of 10.9 to 27.8 years (hazard ratio [HR], 10.7; 95% CI, 7.7-15.0). Polycythemia refers to an increased hemoglobin concentration and/or hematocrit in peripheral blood. Am J Hematol. Initial standard therapy included hydroxyurea (59% in RESPONSE, 49% in RESPONSE-2); interferon (12% in RESPONSE, 13% in RESPONSE-2); or no medication (15% in RESPONSE, 28% in RESPONSE-2). Leukocytosis as an important risk factor for arterial thrombosis in WHO-defined early/prefibrotic myelofibrosis: an international study of 264 patients. 2016;128(22)(suppl). Diagnosis of polycythemia vera requires all 3 major criteria OR the first 2 major criteria and the minor criterion. 9. The goal in polycythemia vera is to keep the hematocrit below 45.

Background: Recommendations for phlebotomy to treat erythrocytosis of Secondary Polycythemia (SP) are largely reactive and based on limited evidence acknowledging quality of life (QOL) metrics and thrombotic risk over Hct >54%. Results. Polycythemia vera (PV) is a stem cell disorder characterized as a panhyperplastic, malignant, and neoplastic marrow disorder. Eligible patients were randomly allocated (1:1) to receive either phlebotomy and low-dose aspirin (standard group) or ropeginterferon alfa-2b on top of the standard treatment (experimental group). 54. Phlebotomy is often the first treatment for polycythemia vera. 2014;123(24):3803-3810. Relation between JAK2 (V617F) mutation status, granulocyte activation, and constitutive mobilization of CD34+ cells into peripheral blood in myeloproliferative disorders. 12. Each discrete variable was assigned a risk point (obtained by rounding the risk coefficients): 2 points for hemoglobin level below 11 g/dL, at least 3% circulating blasts, and CALR-unmutated genotype; 1 point for platelet count below 150 × 109/L and for the presence of constitutional symptoms. Distinct clustering of symptomatic burden among myeloproliferative neoplasm patients: retrospective assessment in 1470 patients. on What is the treatment for itching as a result of polycythemia vera? Hematology Am Soc Hematol Educ Program. Silver RT, Krichevsky S, Gjoni S, Cross NCP. Passamonti F, Griesshammer M, Palandri F, et al. A complementary method, because patients with polycythemia vera are at increased risk of blood clots, is also low-dose aspirin therapy. 24. Am J Hematol. It's a lot like donating blood. Polycythemia vera (PV) may develop slowly and remain unrecognized for years. Hemoglobin level > 165 g/L in men, > 160 g/L in women OR hematocrit > 0.49 in men, > 0.48 in women OR increased erythrocyte mass Italy Johansson PL, Safai-Kutti S, Kutti J. Criteria for hydroxyurea intolerance and resistance for clinical trials (not for clinical practice) have been proposed thanks to an international effort.64 Recently, a Spanish study provided the size of this condition: overall, the criteria for hydroxyurea intolerance or resistance were found in 15% of 890 patients with PV. 43. 58. Abstract: Polycythemia vera (PV) is a Philadelphia chromosome–negative chronic myeloproliferative neoplasm that is associated with a Janus kinase 2 (JAK2) mutation in most cases. A total of 168 patients have been enrolled, without significant differences in clinical presentation noted between the 2 groups. You'll usually feel better, too. Hydroxyurea is generally well tolerated and only rarely associated with the development of significant side effects, such as leg ulcers and gastrointestinal toxicity (eg, nausea, diarrhea). In an initial analysis of 685 molecularly annotated SMF cases, all patients with PPV-MF carried the JAK2 V617F mutation, and the driver mutation distribution in PET-MF appeared similar to that in PMF, although a direct comparison was clearly not feasible.40 Furthermore, the analysis disclosed that survival varied significantly according to genotype, with patients who had CALR-mutated PET-MF living longer than those who had JAK2-mutated PPV-MF or PET-MF. Efficacy of pipobroman in the treatment of polycythemia vera: long-term results in 163 patients. Br J Haematol. Low-risk patients are commonly treated with phlebotomy and antiplatelet therapy, whereas high-risk patients receive cytoreductive treatment in addition to low-dose aspirin (depending on the type and date of the previous thrombotic event, oral anticoagulation may be indicated instead of low-dose aspirin).33, The ideal target hematocrit for either phlebotomy or cytoreduction has long been unclear, resulting in different approaches that largely depend on the clinician’s inclination. Blood. In patients whose disease fails to respond to hydroxyurea, ruxolitinib is a safe and effective choice. Two prospective, randomized studies, RESPONSE (Study of Efficacy and Safety in Polycythemia Vera Subjects Who Are Resistant to or Intolerant of Hydroxyurea: JAK Inhibitor INC424 Tablets Versus Best Available Care) and RESPONSE-2 (Ruxolitinib Efficacy and Safety in Patients With HU Resistant or Intolerant Polycythemia Vera vs Best Available Therapy), have reported data in the last 2 years.65,66 RESPONSE included 222 patients with hydroxyurea intolerance/resistance, need of phlebotomy, and splenomegaly, and RESPONSE-2 included 173 patients with the same entry criteria except for splenomegaly. Haematologica. And so the simplest way of doing that is with phlebotomy, so that’s usually the first method that we use in patients. No cases of grade 3/4 anemia or thrombocytopenia occurred in the patients treated with ruxolitinib. 2015;26(suppl 5):v85-v99. Such conditions include congenital erythrocy- JAK2 stimulates homologous recombination and genetic instability: potential implication in the heterogeneity of myeloproliferative disorders. See Some symptoms will get better, such as headaches or dizziness. PRV-1 and its correlation with treatments and disease status in 210 patients with polycythemia vera and essential thrombocythemia. Diagnosing the specific cause of polycythemia is important for proper management of the patient. Haematologica. The hematologist’s challenges when treating Polycythemia Vera (PV) include reduction in the risk of incident or recurrent thrombosis and/or hemorrhage, palliation of symptoms, minimization of long-term consequences of therapy, delay of progression and management during special situations, such as the peri-operative period.1 Often, cytoreduction is prescribed as a complement to phlebotomy … The study was designed as a noninferiority trial, with complete hematologic remission at 12 months being the primary endpoint. Rotunno G, Pacilli A, Artusi V, et al. 2003;88(1):13-18. The 2016 WHO diagnostic criteria for polycythemia vera renders an accurate diagnosis to a broader range of patients including masked polycythemia vera: comparison with the 2008 WHO diagnostic criteria. Overall, 45% of patients have had a hematologic response, without significant differences noted between the 2 treatments. Symptomatic splenomegaly or disease-related symptoms may be an indication to start cytoreduction.9,55,56.
