Assessment and prognostic value of the European LeukemiaNet criteria for clinicohematologic response, resistance, and intolerance to hydroxyurea in polycythemia vera. Rambaldi A, Dellacasa CM, Finazzi G, et al. According to the negative binomial model, the annual rate of AML transformation was 0.4%, although the logistic model suggests a slight tendency to increase after around eight years. Remarkably, history of thrombosis was not a significant predictor of thrombosis risk in meta-regression. 2016 Apr;21(4):475-80. doi: 10.1634/theoncologist.2015-0380. Studies have shown that early initiation of therapy with interferons can lead to sustained remission in patients with myeloproliferative disorders[27,28]. Copyright 2019 Ferrata Storti Foundation. In this way we mitigated any possible distortion. The selection included three reports on two RCT4,17,18 (one comparing HU and IFN therapy, and one comparing HU to ruxolitinib), one RCT in which HU was not a comparator,19 and 12 observational retrospective cohort studies.7,2033 The great majority of the studies were conducted in Europe and some involved multiple countries; only one study in our selection32 was conducted in the US. Incidence of each outcome was calculated and is reported as number of events per 100 persons/year. Abstract From 1963 to 1983, I treated 100 patients with polycythemia vera, using phlebotomy and the adjunctive agent hydroxyurea. It was originally developed to be used as an anticoagulant, but it surprisingly showed potential in essential thrombocythemia[21]. 19.79. Internal Medicine, Government Medical College and Hospital, Chandigarh, Chandigarh, IND. Side Effects Polycythemia vera is a type of slow-growing neoplasm, localized to the bone marrow, whose chief manifestation is an excessive production of red blood cells.

The current role of various cytoreductive drugs has been summarized in Table1. N Engl J Med. Overall, demographics were incomplete or not stratified by HU treatment (6 studies), cardiovascular risk factors were missing (10 studies), and history of thrombosis was not reported (6 studies), antithrombotic drug therapy was not mentioned in ten studies.

Two important drugs belong to this class, nutlin-3 and idasanutlin. A reappraisal of the benefit-risk profile of hydroxyurea in polycythemia vera: A propensity-matched study. Figure 3 shows probability of each outcome in follow up as predicted by regression models when all confounders are kept fixed at their weighted mean value, with estimated ICC and relative statistical tests of heterogeneity. THE LEUKEMOGENIC risk attributed to therapy of polycythemia vera (PV) with 32 P 1,2 has led, over the last 20 years, to the increased use of myelosuppressive drugs, especially hydroxyurea (HU). [43]. The site is secure. Leuk Lymphoma. Cingam S, Flatow-Trujillo L, Andritsos LA, Arana Yi C.

Mesa R, Boccia RV, Grunwald MR, et al. official website and that any information you provide is encrypted Epub 2022 Apr 13. With regard to hematologic transformations, we observed that annual incidence of AML is fairly constant and the cumulative 10-year incidence is approximately 4% (0.4% patients/year). Higher incidence of arterial events was predicted by previous cardiovascular complication. Benefits and harms of hydroxyurea therapy in polycythemia vera, PROSPERO: International prospective register of systematic reviews, Methodology for JBI Scoping Reviews. Number of HU-treated patients ranged from 25 to 890 across studies; the final meta-analysis was conducted on a total of 3,236 patients in whom HU therapy was consistently administered. Hydroxyurea/hydroxycarbamide or interferons can be used as first-line drugs. Landolfi R, Marchioli R, Kutti J, Gisslinger H, Tognoni G, Patrono C, Barbui T. No correlation of intensity of phlebotomy regimen with risk of thrombosis in polycythemia vera: evidence from European Collaboration on low-dose aspirin in polycythemia vera and cytoreductive therapy in polycythemia vera clinical trials. Anagrelide and busulfan are third-line drugs. The .gov means its official. Based on 2,552 patients and 469 events, estimates of thrombosis incidence rate in patients with a median age of 60, 70 and 80 years under HU treatment are 1.6%, 3.6% and 6.8%, respectively. From efficacy to safety: a Polycythemia Vera Study group report on hydroxyurea in patients with polycythemia vera. Ruxolitinib, a promising novel agent in the management of PV, directly targets the primary pathogenetic mutation implicated in PV (JAK2V617F). Results from logistic regression are detailed in Online Supplementary Table S1. eCollection 2022 Jan. Leukemia. Currently, use of ruxolitinib is limited to PV resistant to hydroxyurea and in cases of intolerance to hydroxyurea[6]. documented the development of resistance to hydroxyurea therapy. De Stefano V, Ruggeri M, Cervantes F, et al. Ruxolitinib versus standard therapy for the treatment of polycythemia vera. Terms used in research for primary end points were polycythemia vera and hydroxyurea/hydroxycarbamide and thrombosis and myelofibrosis. The identification of this mutation has led to the discovery of novel treatment options, which have revolutionized the management of PV. It has been approved for use in PV in patients without symptomatic splenomegaly and as monotherapy as well[32]. Vannucchi AM, Guglielmelli P. How I treat polycythemia vera. Treatment strategies in PV have evolved in the past few years. The number of second cancers was too small and between-study heterogeneity too high to allow for reliable inference on this outcome. Vannucchi AM. Patient Education Boxed Warning Bone marrow suppression (Droxia, Siklos): Hydroxyurea may cause severe myelosuppression. This disease is recognized for its distinct molecular profile (JAKV 617F mutation) and has a characteristic natural history marked by high frequency of thrombosis and a tendency to transform into acute myelogenous leukemia (AML) or myelofibrosis (MF). Safety and efficacy of the maximum tolerated dose of givinostat in polycythemia vera: a two-part Phase Ib/II study. Leukemia. Based on 59 events on 755 patients, pooled incidence of second cancer was 1.7% persons/year (95%CI: 1.3-2.2%), mainly comprising non-melanoma skin cancer. Pegylated interferons were introduced to overcome this major disadvantage, and they also offer a better side effect profile[29]. However, this is not surprising in meta-regression analysis, since it is prone to the ecological bias, i.e. Hintermair S, Zwickl-Traxler E, Pecherstorfer M, et al. Treatment modalities for polycythemia vera (PV) have evolved over time. Before Mortality (B). Philadelphia chromosome-negative classical myeloproliferative neoplasms: revised management recommendations from European LeukemiaNet. However, estimates of its effect in terms of clinical outcomes (thrombosis, bleeding, hematologic transformations and mortality) are lacking. Ropeginterferon alfa-2b is a novel interferon with an increased half-life, allowing for a simplified dosing regimen, a major limiting factor of traditional interferons[29]. Interferon alfa is especially useful for PV symptoms, and the newer preparation, ropeginterferon alfa-2b, has lesser incidence of flu-like reactions. First line or second line (when interferons are used as first line), First line or second line (when hydroxyurea is used as first line), Third line (only in combination with hydroxyurea), Third line (in patients with limited life expectancy). administered bulsulfan to six patients with PV refractory to all other cytoreductive therapies and achieved complete hematological response in all of the them within three months. A phase 2 study of ruxolitinib, an oral JAK1 and JAK2 Inhibitor, in patients with advanced polycythemia vera who are refractory or intolerant to hydroxyurea. Contrary to the commonly held view, we did not find a statistically significant effect of history of thrombosis on incidence of new vascular events. Duplicate records were individually checked and merged using reference managing software. sharing sensitive information, make sure youre on a federal Hydroxyurea is currentlythe most widely prescribed drug. Unable to load your collection due to an error, Unable to load your delegates due to an error, Forest plot of outcomes incidences. We performed a meta-analysis to determine the absolute risk of events in r Polycythemia vera (PV) is a BCR-ABL1 -negative myeloproliferative neoplasm (MPN) characterized by excessive proliferation of erythroid, myeloid, and megakaryocytic components in the bone. . Not only were the symptoms ameliorated with this novel agent, but also the hematocrit and complete blood counts normalized, and a resolution of splenomegaly was also noted[14]. Vascular and neoplastic risk in a large cohort of patients with polycythemia vera. Marchioli R, Finazzi G, Specchia G, et al. . Droxia is a trade name for Hydroxyurea. The clinical spectrum of PV is vast from being detected incidentally to a full blown picture with typical signs and symptoms chiefly pertaining to increased red blood cell (RBC) number and mass, thereby leading to increased blood viscosity. Studies not reporting follow-up duration were excluded. Lu M, Wang X, Li Y, et al. the contents by NLM or the National Institutes of Health. Table 3. While most studies referred to events after first-line therapy, three focused on recurrent thromboses. This rate does not seem to change over follow-up time, as shown by a comparison between a logistic and a negative binomial model, and depends on age. Two studies referred to the same population4,17 but reported different outcomes; therefore, we did not consider it as a duplicate for the aims of our analysis. Bethesda, MD 20894, Web Policies Myeloproliferative neoplasms (MPN) can occur when abnormal stem cells in your bone marrow cause your body to overproduce red blood cells, white blood cells and/or platelets. Studies have shown that hydroxyurea has a better effect on JAK2V617F mutation-harboring cells as compared to anagrelide[23]. This was associated with an increased risk of mortality (5.6 fold) and transformation to acute leukemia (6.8 fold) in patients developing resistance[13]. the loss of information that follows from dealing with aggregate data.36 This mirrors the effect of increasing age on the thrombotic risk of the general population observed either for arterial or thrombotic events.37,38 However, we highlight the fact that the residual incidence of thrombosis in HU-treated PV patients is still elevated, corresponding to approximately 3-fold higher than that estimated in the general population.37 It is, therefore, advisable to promote new pharmacological strategies and to consider our reported thrombosis rate as a benchmark for future comparative studies. and transmitted securely. Huang BT, Zeng QC, Zhao WH, Li BS, Chen RL. De Stefano V, Vannucchi AM, Ruggeri M, et al. An official website of the United States government. Gisslinger H, Klade C, Georgiev P, et al. 10.1002/cncr.22026 Abstract Patients with polycythemia vera (PV) are most often treated with phlebotomy-only (PHL-O) or phlebotomy plus hydroxyurea (PHL + HU). Verstovsek S, Passamonti F, Rambaldi A, et al. it was impossible to distinguish data due to HU-treated patients from those due to other cytoreductive treatments, or PV from other myeloproliferative neoplasms). This alternative was clearly proposed in the recently published conclusion of the studies conducted by the Polycythemia Vera Study Group (PVSG).3 However, there has been no large-scale, long-term . Many clinical trials have been performed to investigate the efficacy of ropeginterferon alfa-2b, the most important ones being PROUD-PV and its extension CONTINUATION-PV[33]. The study selection process is detailed in Figure 1. Fruchtman SM, Mack K, Kaplan ME, Peterson P, Berk PD, Wasserman LR. Hydroxyurea is the standard treatment in high-risk patients with polycythemia vera. Res Pract Thromb Haemost. In conclusion, this meta-analysis provides reliable risk estimates for thrombosis, hemorrhage, evolution to MF and AML, and mortality in PV patients under standard treatment with HU. A guideline for the diagnosis and management of polycythaemia vera. All content published within Cureus is intended only for educational, research and reference purposes. The "French Cooperative Group for the Study of Polycythaemias". Average incidence rate was 3.3% persons/year, ranging from 1.9% at 60 years of age with no history of thrombosis to 6.8% at a median age of 80 years. However, many clinicians are reluctant to use it because of the perceived risk of . We searched for relevant articles or abstracts in the following databases: Medline, EMBASE, clinicaltrials.gov, WHO International Clinical Trials Registry, LILACS. Sixteen studies published from 2008 to 2018 reporting number of events using World Health Organization diagnosis for polycythemia vera were selected. Was 21.99. Based on 88 events over 1,485 patients, pooled incidence of bleeding was 1% per year, independently of follow-up duration or antithrombotic therapy, as shown by meta-regression. An official website of the United States government. Alvarez-Larrn A, Pereira A, Cervantes F, et al. This indicates that, for practical purposes, thrombosis incidence rate can be assumed to be constant over time, at least up to a 10-year observation period. This combination serves as a first-line treatment option for patients with low-risk disease and can be used in addition to cytoreductive therapy in patients belonging to the high-risk group[8]. Monitoring Editor: Alexander Muacevic and John R Adler. The incidence is not graphed for Mesa, Outcomes incidence during follow up according to logistic Generalized Linear Mixed Model (GLMM) and comparison with negative-binomial model. Myelofibrosis (C). Seven studies referred to cases diagnosed outside the time window (2008-2018) and not with WHO 2008-2016 criteria. Comparison between anagrelide and hydroxycarbamide in their activities against haematopoietic progenitor cell growth and differentiation: selectivity of anagrelide for the megakaryocytic lineage. In particular, with the exception of AML, for the other outcomes, 95% confidence intervals do not always overlap between studies. Interferon-alpha should be reserved for selected categories of patients due to high cost and toxicity. On the other hand, in a sub-analysis on arterial and venous thrombotic events, previous thrombosis was a highly significant (P<0.001) predictor of incidence of arterial thrombosis, but not of venous. We searched for articles or abstracts published between 2008 and 2018 in the following databases: Medline, EMBASE, clinicaltrials.gov, WHO International Clinical Trials Registry (for unpublished or ongoing trials), LILACS. Where to Turn for Second-Line Cytoreduction After Hydroxyurea in Polycythemia Vera? In case of multiple studies from the same author(s), we inquired whether they referred to overlapping populations, by questioning authors when necessary, and excluded duplicates (6 studies) from review. Alvarez-Larrn A, Garrote M, Ferrer-Marn F, Prez-Encinas M, Mata-Vazquez MI, Bellosillo B, Arellano-Rodrigo E, Gmez M, Garca R, Garca-Gutirrez V, Gasior M, Cuevas B, Angona A, Gmez-Casares MT, Martnez CM, Magro E, Ayala R, Del Orbe-Barreto R, Prez-Lpez R, Fox ML, Raya JM, Guerrero L, Garca-Hernndez C, Caballero G, Murillo I, Xicoy B, Ramrez MJ, Carreo-Tarragona G, Hernndez-Boluda JC, Pereira A; MPN Spanish Group (Grupo Espaol de Enfermedades Mieloproliferativas Filadelfia Negativas).

Both complete and partial hematological recoveries were documented in addition to improvement in splenomegaly and pruritus. We performed a meta-analysis to determine the absolute risk of events in recent cases of patients under hydroxyurea treatment. In one, follow-up data were missing. The first step in approaching an individual patient with PV is to identify the potential risk of developing major thrombotic or hemorrhagic complications. However, in spite of missing data, in each of these studies we were able to retrieve the number of events for at least one outcome. National Library of Medicine There is no consensus recommendation for its use in PV, although some clinicians use it in patients with platelet counts of >1500 x 109/L[22]. Rambaldi A, Lurlo A, Vannucchi AM, et al. No evidence of excess heterogeneity was found in meta-regression for MF (P=0.281) or AML (P=1.000) once adjusted for potential confounders, as opposed to mortality and thrombosis, where a small but non-zero amount of heterogeneity was observed despite adjustment. Epub 2023 Jan 13. Serious side effects of Hydrea include However, a possible limitation of our analysis is that most reports did not specifically address our study questions, and consequently the relative estimates are based on raw frequency data extracted from descriptive tables or text. Inclusion in an NLM database does not imply endorsement of, or agreement with, 8600 Rockville Pike Interferon alpha improves the symptom profile inPV patients with control of pruritus, paresthesia, and erythromelalgia[26]. However, using the median as an estimator of mean has been shown to be reliable in most cases.39. Semin Hematol. reported an excellent clinical efficiency ofidasanutlin therapy in their study. RG7112is another drug closely related to nutlin-3with even better potency. Hydroxyurea works by inhibiting DNA synthesis and causing cell death. Interferon -2b gains high sustained response therapy for advanced essential thrombocythemia and polycythemia vera with JAK2V617F positive mutation. 2022 Feb 7;6(1):e12657.

Ropeginterferon Alfa-2b Induces High Rates of Clinical, Hematological and Molecular Responses in Polycythemia Vera: Two-Year Results from the First Prospective Randomized Controlled Trial. However, the use of interferons is not devoid of adverse effects, the common ones being flu-like symptoms, back and joint pain. Do not disregard or avoid professional medical advice due to content published within Cureus. MF: myelofibrosis; AML: acute myeloid leukemia. Phlebotomy and low-dose aspirin suffice in low-risk patients, but cytoreductive therapies are indicated in all high-risk patients (age 65 years or those with a history of PV-related thrombotic event) and may be considered for low-risk patients with progressively increasing splenomegaly, progressively increasing leucocyte and platelet counts, and for those who do not tolerate phlebotomy.

J Clin Oncol. 8600 Rockville Pike Adjusted estimates for annual incidence of thrombosis are reported in Table 2, globally and stratified by median age and previous thrombosis. Furthermore, by adjusting for study-specific covariates, we were able to account for the effect of the most relevant confounders, which for some outcomes (namely MF and AML) allowed us to reduce heterogeneity to negligible values. June 19, 2019 For Thrombocythemia "Started on 500mg hydroxyurea and got swollen tongue but not anaphylaxis. Can pegylated interferon improve the outcome of polycythemia vera patients?

Epub 2012 Dec 8. Overall incidence of thrombosis in our population was approximately 3% per year, obtained by pooling together event rates from each study. FOIA Use of published material is allowed under the following terms and conditions: studies in English language published in the period 2008-2018 using WHO diagnostic criteria for PV; studies on adult (aged 18 years) non-pregnant patients; RCT, prospective and retrospective cohort studies reporting frequency of outcomes of interests (thrombotic and/or hemorrhagic events and/or hematologic transformations in adult patients) stratified by HU therapy, as reported by authors; Barbui T, Tefferi A, Vannucchi AM, et al. These symptoms produce significant morbidity and loss of productivity[3]. Cytoreductive therapy with either hydroxyurea (HU), a ribonucleotide reductase inhibitor considered non-mutagenic, or interferon-alfa (IFN) are appropriate first-line drugs to prevent vascular complications in high-risk patients (age >60 years and/or prior thrombosis).1, Hydroxyurea was recommended in the treatment of high-risk PV based on the results of the Polycythemia Vera Study Group (PVSG) protocol 08 in which this drug was found to be effective in reducing the rate of thrombotic events in 51 patients compared to historical controls treated with PHL alone.2 Very few studies were designed to confirm these conclusions. Barbui T, Vannucchi AM, Carobbio A, et al. Hence, HDAC inhibitorsare potentially anti-oncogenic in nature. We have now several observational studies reporting single or multicenter experience regarding the risk-estimates of clinical events associated with HU.

Oral idasanutlin in patients with polycythemia vera. Bookshelf Accessibility 5705185. These are especially important in a scenario of emerging resistance and intolerance to hydroxyurea. The final selection comprised 14 full text articles and two conference abstracts to be included in the meta-analysis. The method assumes that probability of displaying the event at time zero is the same across the studies, but it increases as a function of follow-up duration at a study-specific rate under the effect of selected covariates. Careers. It can also cause vague but irritating symptoms, such as skin itchiness, ringing in your ears, abdominal pain, nose bleeds and blurred or double vision. We were unable to retrieve full information from two additional reports4,29 but, in spite of this, we were able to extract incidence of at least one of the outcomes of interest. Overall, 3,236 patients were analyzed. This estimate does not account for heterogeneity across studies, yet a meta-regression analysis accounting for study-specific confounders, such as median age, antithrombotic therapy, CV risk factors and history of thrombosis, provides a slightly lower estimate (2.8%).
