What is the treatment for polycythemia vera?
Treatment modalities for polycythemia vera (PV) have evolved over time. 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. Hydroxyurea/hydroxycarbamide or interferons can be used as first-line drugs. Hydroxyurea may not be tolerated by some patients, and it also carries risk of myelosuppression. Interferon alfa is especially useful for PV symptoms, and the newer preparation, ropeginterferon alfa-2b, has lesser incidence of flu-like reactions. Ruxolitinib reduces the JAK2V617F mutation burden and is used as a second-line drug. Anagrelide reduces platelet production and can be used in conjunction with hydroxyurea in patients with excessive thrombocytosis. The alkylating agent, busulfan, can also be used as a last resort in patients with a limited life expectancy. Prospective future treatments include givinostat, a histone deacetylase inhibitor, and idasanutlin, a murine double minute 2 antagonist.
What is the best treatment for PV?
Treatment options for PV have evolved with time. Phlebotomy with low-dose aspirin forms the standard of care for low-risk patients, and cytoreductive therapies are indicated in high-risk cases and some low-risk cases. Hydroxyurea is currently the most widely prescribed drug. Recent studies have established the safety and efficacy of ruxolitinib and ropeginterferon alfa-2b in the management of PV. These are especially important in a scenario of emerging resistance and intolerance to hydroxyurea. Anagrelide and busulfan are third-line drugs. 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.
What is hydroxyurea used for?
This well-known drug is one of the most widely used cytoreductive agents with wide application in the management of PV. It acts by inhibiting the enzyme ribonucleoside reductase and thus inhibits deoxyribose nucleic acid (DNA) synthesis [10]. It is the first-line cytoreductive agent in patients with high-risk PV [11]. Its undesirable action is predominantly on the hematopoietic system, frequently leading to myelosuppression. Intolerance to hydroxyurea is fairly common, probably due to adverse effects like mucositis, ulceration, dermatitis, and development of skin cancer [12]. Alvarez-Larrán et al. documented the development of resistance to hydroxyurea therapy. 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]. Hence, additional studies are needed to study the phenomenon of resistance.
What is PV in biology?
Polycythemia vera (PV), one of the myeloproliferative malignancies, is characterized by clonal proliferation of hematopoietic cells, chiefly erythrocytes. The pathophysiology of myeloproliferative disorders is based on the presence of certain genetic mutations. A majority of the cases of PV are accompanied by Janus kinase-2 (JAK-2) mutations, mainly the JAK2V617F mutation [1]. 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]. The identification of this mutation has led to the discovery of novel treatment options, which have revolutionized the management of PV. 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. This predisposes to thrombotic complications along with hemorrhagic complications due to production of dysfunctional platelets. There is increased synthesis of various cytokines, which leads constitutional features such as fever, pruritus, weight loss, and anorexia. These symptoms produce significant morbidity and loss of productivity [3]. The cornerstone of management includes reducing thrombotic events, managing constitutional symptoms, and halting the progression of malignancy while minimizing side effects associated with various therapeutic modalities [4].
Is ruxolitinib effective in PV?
Ruxolitinib, a promising novel agent in the management of PV, directly targets the primary pathogenetic mutation implicated in PV (JAK2V617F). It was approved by the Food and Drug Administration (FDA) in 2014. Focus was shifted to this drug in view of emerging resistance to and side effect profile of hydroxyurea. Verstovsek et al. reported excellent clinical efficacy of ruxolitinib in their patient’s refractory or intolerant to hydroxyurea. 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]. Ruxolitinib was found to improve the clinical picture better than the previously available therapeutic modalities in the RESPONSE trial as well [15]. Its effect at the molecular level was prominent with reduction of JAK2V617F mutation burden in PV patients [16]. Ruxolitinib was also shown to be effective in hydroxyurea-resistant/intolerant patients without splenomegaly [17]. This drug is not free of adverse effects, which include anemia, thrombocytopenia, herpes zoster reactivation, and development of non-melanomatous skin cancers. Vaccination to prevent reactivation of zoster is thus advocated prior to treatment [15,18]. Evidence-based medicine has revealed the favorable potential of ruxolitinib in PV, with alleviation of symptoms and improved patient-reported outcomes and quality of life [19]. A study to uncover the potential of momelotinib (a similar JAK inhibitor) in PV was also conducted but terminated due to low efficacy [20]. Currently, use of ruxolitinib is limited to PV resistant to hydroxyurea and in cases of intolerance to hydroxyurea [6].
Does interferon alpha help with RBC?
Interferon alpha limits RBC proliferation in PV. It remains one of the first-line treatment options for PV, especially in pregnant females [24]. Its clinical efficacy has been reported to be excellent, similar to that of hydroxyurea [25]. Interferon alpha improves the symptom profile in PV patients with control of pruritus, paresthesia, and erythromelalgia [26]. Studies have shown that early initiation of therapy with interferons can lead to sustained remission in patients with myeloproliferative disorders [27,28]. However, the use of interferons is not devoid of adverse effects, the common ones being flu-like symptoms, back and joint pain. Some of the serious toxicities include hematological changes like anemia and lymphopenia, and interferon therapy has also been linked to occurrence of autoimmune disorders [26]. Another drawback of interferon use is the tedious dosing regimen (thrice weekly injections, approximately three million units per dose). Pegylated interferons were introduced to overcome this major disadvantage, and they also offer a better side effect profile [29]. 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]. The most commonly reported adverse effects with its use include malaise, myalgias, nausea, vomiting, and depressive episodes [29]. 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.
Is anagrelide used for thrombocythemia?
Anagrelide is an antithrombotic and platelet-reducing agent that is also being used to treat thrombocythemia associated with other myeloproliferative diseases. It is an anti-platelet drug with co-incidental cytoreductive action. It was originally developed to be used as an anticoagulant, but it surprisingly showed potential in essential thrombocythemia [21]. However, its use in PV is limited to where reduction in platelet counts is required. 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]. Studies have shown that hydroxyurea has a better effect on JAK2V617F mutation-harboring cells as compared to anagrelide [23]. 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.
