Ten of 16 patients with thrombosis (62.5 percent) 2 in the hydroxyurea group . Bookshelf The https:// ensures that you are connecting to the Epub 2022 Apr 13. The advantage of this model is that it uses an exact binomial likelihood and error structure, and naturally accounts for heterogeneity in sample sizes.1416 For meta-regression, missing data about confounders were imputed to the sample size-weighted mean of the other studies. Rambaldi A, Lurlo A, Vannucchi AM, et al. On the other hand, the fact that the studies did not address our question makes publication bias in favor of certain results very unlikely. the contents by NLM or the National Institutes of Health. Larsen TS, Mller MB, de Stricker K, et al. . Hydroxyurea is the standard treatment in high-risk patients with polycythemia vera. Thrombosis incidence by age and history of thrombosis. Overall incidence of thrombosis in our population was approximately 3% per year, obtained by pooling together event rates from each study. HHS Vulnerability Disclosure, Help Important adverse effects include diarrhea, thrombocytopenia, and increased serum creatinine levels[40]. 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 . Check the online version for the most updated information on this article, online supplements, and information on authorship & disclosures: www.haematologica.org/content/104/12/2391, National Library of Medicine This response kept on increasing with continued administration[29]. These findings can help design comparative clinical trials with new cytoreductive drugs and prove the feasibility of using critical end points for efficacy, such as major thrombosis. A 68-year-old women with polycythemia vera was treated with hydroxyurea for 8 years and developed painful ulcers on her lower legs, multiple hypertrophic actinic keratoses and a squamous cell carcinoma. and transmitted securely. This decreases your blood volume and reduces the number of excess blood cells. et al. A synergistic effect was observed when givinostat was combined with hydroxycarbamide, with better control of pruritus and improvement in cell counts[39]. Only two studies in our selection reported HU-associated adverse events, which does not allow reliable estimates to be made. HHS Vulnerability Disclosure, Help Studies have shown that low-dose pegylated interferon alpha 2 has an even better efficacy when given in combination with ruxolitinib, characterized by improvement in cell counts and the bone marrow picture, reduced JAK2V617F mutation burden, and adequate amelioration of symptoms[30]. Ruxolitinib, a promising novel agent in the management of PV, directly targets the primary pathogenetic mutation implicated in PV (JAK2V617F). 2022 Jul 1;128(13):2441-2448. doi: 10.1002/cncr.34195. The number of second cancers was too small and between-study heterogeneity too high to allow for reliable inference on this outcome. 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). Marchioli R, Finazzi G, Specchia G, et al. Mascarenhas J, Lu M, Kosiorek H, et al. Thrombosis in myeloproliferative neoplasms during cytoreductive and antithrombotic drug treatment. For myelofibrosis, rates were 5.0 at five years and 33.7% at ten years; overall mortality was 12.6% and 56.2% at five and ten years, respectively. We have now several observational studies reporting single or multicenter experience regarding the risk-estimates of clinical events associated with HU. Hence, HDAC inhibitorsare potentially anti-oncogenic in nature. Mascarenhas et al. 8600 Rockville Pike Persons/year were estimated by multiplying mean follow-up duration by number of HU-treated patients; when mean follow-up duration was not available, median duration was deemed to be a reasonable approximation. Recent studies have established the safety and efficacy of ruxolitinib and ropeginterferon alfa-2b in the management of PV. From efficacy to safety: a Polycythemia Vera Study group report on hydroxyurea in patients with polycythemia vera. The site is secure. This results in a nucleotide switch and, in turn, a qualitative genetic abnormality resulting in replacement of valine by phenylalanine at codon 617 on chromosome 9[2]. In contrast, annual incidence of evolution into MF, as predicted by meta-regression, increases steeply after five years of follow up. official website and that any information you provide is encrypted Rambaldi A, Dellacasa CM, Finazzi G, et al. 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 . This can be a valid point of reference for the clinician. Side effects (autoimmune disorders, flu-like manifestations, depression, heart, and ocular disease) lead to permanent discontinuation in 20% to 40% on conventional and 20% to 25% on pegylated interferon. The 2016 revision to the World Health Organization classification of myeloid neoplasms and acute leukemia. 8600 Rockville Pike Studies aimed specifically at HU-resistant patients were excluded. These symptoms produce significant morbidity and loss of productivity[3]. Outcomes incidence during follow up according to logistic Generalized Linear Mixed Model (GLMM) and comparison with negative-binomial model. Currently, use of ruxolitinib is limited to PV resistant to hydroxyurea and in cases of intolerance to hydroxyurea[6]. Federal government websites often end in .gov or .mil. A narrative review has been prepared using review articles and clinical trials to reflect the current footing of various drugs and possible future treatments. Am J Hematol. Unauthorized use of these marks is strictly prohibited. Overall, regression analysis of MF and AML was only adjusted for age. The alkylating agent, busulfan, can also be used as a last resort in patients with a limited life expectancy. Careers, Unable to load your collection due to an error. Overall, 3,236 patients were analyzed. Histone deacetylase (HDAC) is an enzyme that downregulates the expression of tumor suppressor genes. It is the first-line cytoreductive agent in patients with high-riskPV[11]. Focus was shifted to this drug in view of emerging resistance to and side effect profile of hydroxyurea. [Cutaneous side effects of hydroxyurea treatment for polycythemia vera] Hautarzt. doi: 10.1002/rth2.12657. Antonioli E, Guglielmelli P, Pieri L, et al. Barbui T, Tefferi A, Vannucchi AM, et al. Mesa R, Boccia RV, Grunwald MR, et al. Marchioli R, Finazzi G, Landolfi R, et al. Griesshammer M, Saydam G, Palandri F, et al. The mutation burden was also found to be decreased[38]. Overall, 3,236 patients were analyzed. A reappraisal of the benefit-risk profile of hydroxyurea in polycythemia vera: A propensity-matched study. PMC Estimates increase with median age and are higher in presence of history of thrombosis, but the latter difference is not statistically significant. Updates in the management of polycythemia vera and essential thrombocythemia. Large clinical trials are needed to evaluate the efficacy and safety of this novel agent. Lastly, we underline the value of a cheap, old and safe molecule as a reliable and accessible resource for those settings where there is a need to reconcile economic sustainability with the right to a qualitative-quantitative life advantage. More than 250,000 people in the U.S. are living with myeloproliferative neoplasm, diagnosed as essential thrombocythemia (ET), myelofibrosis (MF), polycythemia vera (PV) or . Vannucchi AM. 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]. 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. The incidence is not graphed for Mesa et, Outcomes incidence during follow up according to logistic Generalized Linear Mixed Model (GLMM), MeSH Accessibility Blood withdrawals The most common treatment for polycythemia vera is having frequent blood withdrawals, using a needle in a vein (phlebotomy). Cytoreductive treatment patterns among US veterans with polycythemia vera. In particular, with the exception of AML, for the other outcomes, 95% confidence intervals do not always overlap between studies. Treatment of polycythemia vera with hydroxyurea and pipobroman: final results of a randomized trial initiated in 1980. . 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. investigated its role in PV and essential thrombocythemia, and they documented complete hematological response in 83% of their study population after a median duration of 203 days[36]. Seven studies referred to cases diagnosed outside the time window (2008-2018) and not with WHO 2008-2016 criteria. 8600 Rockville Pike The study selection process is detailed in Figure 1. Lambert PC, Sutton AJ, Abrams KR, Jones DR.

Finazzi G, Vannucchi AM, Martinelli V, et al. Treatment modalities for polycythemia vera (PV) have evolved over time. We, therefore, considered it useful to provide a summary of these results in order to help clinical decision-making and to offer estimates for a more realistic sample calculation in future comparative clinical trials. government site. FOIA These 78 male and 22 female patients ranged in age from 24 to 88 years (mean 55.7). Joanna Briggs Institute Reviewers Manual: 2015 Edition/Supplement, Likelihood-based random-effects meta-analysis with few studies: empirical and simulation studies, The binomial distribution of meta-analysis was preferred to model within-study variability, Use of generalized linear mixed models for network meta-analysis, Final Results from PROUD-PV a Randomized Controlled Phase 3 Trial Comparing Ropeginterferon Alfa-2b to Hydroxyurea in Polycythemia Vera Patients, The efficacy and safety of continued hydroxycarbamide therapy versus switching to ruxolitinib in patients with poly-cythaemia vera: a randomized, double-blind, double-dummy, symptom study (RELIEF). 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. Terms used in research for primary end points were polycythemia vera and hydroxyurea/hydroxycarbamide and thrombosis and myelofibrosis. ICC (Intracluster Correlation Coefficients) and P-values of Likelihood Ratio Tests of random slopes are reported. Barbui T, Tefferi A, Vannucchi AM, et al. The final selection comprised 14 full text articles and two conference abstracts to be included in the meta-analysis. 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. Interferon -2b gains high sustained response therapy for advanced essential thrombocythemia and polycythemia vera with JAK2V617F positive mutation. An official website of the United States government. Accessibility 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). We wish to thank Franca Boschini (Ospedale Papa Giovanni XIII, Bergamo, Italy), for help with database searches and Gianni Tognoni (FROM research foundation, Ospedale Papa Giovanni XIII, Bergamo, Italy), for useful discussion of the results. Anagrelide and busulfan are third-line drugs. 1997;34(1):1723. Kuriakose et al. All content published within Cureus is intended only for educational, research and reference purposes. The protocol of the original review was registered in PROS-PERO (n. CRD4201811781412). Hydroxyurea works by inhibiting DNA synthesis and causing cell death. However, estimates of its effect in terms of clinical outcomes (thrombosis, bleeding, hematologic transformations and mortality) are lacking. Both complete and partial hematological recoveries were documented in addition to improvement in splenomegaly and pruritus. A second strength of our approach is that we managed to greatly reduce the issue of study heterogeneity by using adequate statistical methods, namely a logistic GLMM. Thus, MDM2 antagonists potentially serve as p53 upregulators and have a tumor-suppressing effect. Common side effects of Hydrea include loss of appetite, nausea, vomiting, diarrhea, constipation, sores in the mouth, skin rash, swelling in the hands, feet, legs and face, changes in skin pigmentation, hair loss, painful urination, drowsiness, headache, and dizziness. 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). Srensen AL, Mikkelsen SU, Knudsen TA, et al. Received 2019 Mar 7; Accepted 2019 May 20. National Library of Medicine This may suggest that, under HU treatment, history of thrombosis is no longer a risk factor for recurrences; but it may also be a byproduct of using aggregate data as predictors, with subsequent loss of information on individual patients.36, A third strength is that by extracting data on follow-up duration and integrating them in the analysis, we were able to model the time-dependent evolution of outcome risk, thus overcoming a common bias in meta-analysis of binary outcomes, i.e. Asked to try different brand. . Hydrea capsules work by slowing down the production of the red blood cells. Thus, ropeginterferon alfa-2b could prove to be a game changer in the management of PV in the future. Newer modalities like MDM2 inhibitors and HDAC inhibitors have been found to be effective in certain pilot studies, and more data are needed before they form a part of patient care. Safety and Side Effects. Risk of leukaemia, carcinoma, and myelofibrosis in 32P- or chemotherapy-treated patients with polycythaemia vera: a prospective analysis of 682 cases. 2017;92(11):11311136. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Mortality followed a similar pattern as MF, although the divergence between the two meta-regression models was much less remarkable, with an overlap in 95%CI. Leukemia. and transmitted securely. Epub 2021 Sep 3. Using Hydroxyurea in a Patient With Polycythemia Vera Jun 20, 2018 Srdan Verstovsek, MD: Although we have 2 factors that we use to separate patients in terms of risk for thrombosis (age over 60 and history of thrombosis), there is a possibility that there is a need for introduction of cytoreductive therapy. Through a random effect logistic model, incidences, study heterogeneity and confounder effects were estimated for each outcome at different follow ups. Dashed lines are 95% Confidence Interval (CI), observed frequencies are plotted in hollow circles of size proportional to sample size in person/years. Treatment modalities for polycythemia vera (PV) have evolved over time. sharing sensitive information, make sure youre on a federal Federal government websites often end in .gov or .mil. Incidence of each outcome was calculated and is reported as number of events per 100 persons/year. McMullin MF, Harrison CN, Ali S, et al. 2022 Feb 7;6(1):e12657. Contrary to the commonly held view, we did not find a statistically significant effect of history of thrombosis on incidence of new vascular events. Epub 2016 Mar 14. Hence, additional studies are needed to study the phenomenon of resistance. Among adults, hematologic, gastrointestinal symptoms, infections, headache, anorexia, and dry skin have been commonly reported. 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. Studies have shown that early initiation of therapy with interferons can lead to sustained remission in patients with myeloproliferative disorders[27,28]. 2023 May;102(5):985-993. doi: 10.1007/s00277-023-05172-y. Before A potential source of bias in this respect is our decision to use median follow-up time when the mean was not available, which can lead to biased risk estimates when the actual distribution of follow-up times in the study is very skewed. 2013 Jan 3;368(1):22-33. doi: 10.1056/NEJMoa1208500. Known side effects include: bone marrow suppression (drop in white blood cell, red blood cell and platelet counts), anorexia, nausea, vomiting, diarrhea, constipation, sores in the mouth, skin rash, swelling in the hands, feet, legs and face, changes in skin pigmentation, hair loss, painful urination, drowsiness, A logistic model allows for incidence rates to change over time. Real-world analysis of main clinical outcomes in patients with polycythemia vera treated with ruxolitinib or best available therapy after developing resistance/intolerance to hydroxyurea. Aspirin and hematocrit reduction by venesection or cytoreductive therapy are at the cornerstone of management. Leuk Lymphoma. reported an excellent clinical efficiency ofidasanutlin therapy in their study. 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. Eleven had unclear reporting of data (e.g. As a library, NLM provides access to scientific literature. In a negative binomial regression, yearly incidence is assumed constant over time. Hydroxyurea/hydroxycarbamide or interferons can be used as first-line drugs. Verstovsek et al. Hydroxyurea may not be tolerated by some patients, and it also carries risk of myelosuppression. Verstovsek S, Courby S, Griesshammer M, et al. Bethesda, MD 20894, Web Policies Alvarez-Larrn et al. . Studies not reporting follow-up duration were excluded. 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. Monitoring Editor: Alexander Muacevic and John R Adler. These are especially important in a scenario of emerging resistance and intolerance to hydroxyurea. 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. In the case of duplicate studies on the same sample, the most numerous, or most informative, or most recent study was taken into consideration. documented the development of resistance to hydroxyurea therapy. 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). As opposed to the GLMM, such a model assigns the same weight to each study regardless of sample size and assumes a constant yearly event rate with no upper boundary. Intolerance to hydroxyurea is fairly common, probably due to adverse effects like mucositis, ulceration, dermatitis, and development of skin cancer[12]. Thus, use of anagrelide monotherapy in PV is not recommended, and commencement of this drug along with existing therapy should be considered on a case-to-case basis. Assessment and prognostic value of the European LeukemiaNet criteria for clinicohematologic response, resistance, and intolerance to hydroxyurea in polycythemia vera. Vannucchi AM, Guglielmelli P. How I treat polycythemia vera. However, its use in PV is limited to where reduction in platelet counts is required. Serious side effects of Hydrea include Alvarez-Larrn A, Prez-Encinas M, Ferrer-Marn F, et al. This effect is particularly strong for thrombosis. The therapy had to be discontinued in 30% of all the recipients due to development of bone marrow suppression, and one patient developed acute leukemia. However, this may not be a reliable estimate given the limited number of events and the very large between-study heterogeneity for this outcome. The important side effects of this therapy included diarrhea, fatigue, and nausea. Its clinical efficacy has been reported to be excellent, similar to that of hydroxyurea[25]. The .gov means its official. Internal Medicine, Government Medical College and Hospital, Chandigarh, Chandigarh, IND. Najean Y, Rain JD, Dresch C, Goguel A, Lejeune F, Echard M, Grange MJ. Whenever possible, specific filters were used to exclude case reports, reviews, animal studies and studies on very young patients (aged < 18 years) or pregnant women. Hong Y, Wang G, Arroyo AGD, Hernandez J, Skene C, Erusalimsky JD. Alvarez-Larrn A, Martnez-Avils L, Hernndez-Boluda JC, et al. Through a random effect logistic model, incidences, study heterogeneity and confounder effects were estimated for each outcome at different follow ups. It was originally developed to be used as an anticoagulant, but it surprisingly showed potential in essential thrombocythemia[21]. A study revealed the tremendous potential of this novel drug in PV. 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]. A study to uncover the potential of momelotinib (a similar JAK inhibitor) in PV was also conducted but terminated due to low efficacy[20]. We performed a meta-analysis to determine the absolute risk of events in r the mean) and reported as heterogeneity measure. Since all predictor variables were centered on the mean, predictions are to be interpreted as incidence in the presence of confounding factors equal to the (weighted) mean. Thrombosis (A). A guideline for the diagnosis and management of polycythaemia vera. In an attempt to counteract these undesirable effects and retain the efficacy of this drug, a newer formulation has been devised, known as ropeginterferon alfa-2b. The https:// ensures that you are connecting to the Philadelphia chromosome-negative classical myeloproliferative neoplasms: revised management recommendations from European LeukemiaNet. HIV infections could be stopped at the following steps: (1) at the cell surface, competing molecules could prevent virus attachment; (2) enzyme inhibitors may block the action of reverse transcriptase; (3) integration of the viral genome could be prevented; (4) transcription and translation could be blocked; (5) finally, blocking virion packagin. In some cases, health care professionals may use the trade name Droxia or other trade names Hydrea and Mylocel when referring to the generic drug name Hydroxyurea. How J, Hobbs G. Ruxolitinib and interferon-2 combination therapy for patients with polycythemia vera or myelofibrosis: a phase II study. It has been approved for use in PV in patients without symptomatic splenomegaly and as monotherapy as well[32]. Inclusion in an NLM database does not imply endorsement of, or agreement with, A report on molecular response patterns in seven patients in sustained complete hematological remission. Bethesda, MD 20894, Web Policies Vascular and neoplastic risk in a large cohort of patients with polycythemia vera. Monitor blood counts at baseline and throughout treatment. 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.
