Thomas","doi":"10.2217/IJH.15.1","DOIUrl":"https://doi.org/10.2217/IJH.15.1","url":null,"abstract":"Through the effectiveness of combination chemotherapy and allogeneic stem cell transplantation (ASCT), the cure of acute lymphoblastic leukemia (ALL) in children evolved from the 1970s from an anecdotal wonder to a quantifiable reality. Although giving less spectacular results than those seen in children, these therapeutic approaches have been applied to adults over the last two decades, leading to an improved response rate and survival [1]. Retrospective comparisons demonstrating that adolescents with ALL significantly benefit from pediatric rather than adult chemotherapy regimens yielded to the recent development of pediatric-inspired regimens for adult ALL involving greater dose densities of many chemotherapeutic agents, such as l-asparaginase, vincristine, corticosteroids and methotrexate [2]. However, additional gains are unlikely to be achieved by simply intensifying therapy further, due to the offset of unacceptable toxicities. Furthermore, new procedures for ASCT modestly improve the outcome of adult ALL, while introducing higher risks of acute and late complications. There was therefore a clear and compelling rationale for developing therapies that specifically target the molecular abnormalities that cause leukemia. Encouraging signs have recently emerged with the development of novel therapeutic agents, opening a new era of treatment in adult ALL. Several points of intervention have been identified that may respond to targeted drugs. Concomitantly, the biology of leukemia stem cell (eradication of which is considered as the relevant goal of leukemia therapy) was better understood. Several primary studies with targeted agents have demonstrated impressive clinical activity, even in heavily pretreated patients. Others have demonstrated synergistic effects with chemotherapy and the feasibility of such combinations in clinical trials. The era of targeted therapy for ALL started about 15 years ago with the development of the first inhibitor of tyrosine kinase (TKI), imatinib mesylate [3]. Imatinib mesylate and then the other inhibitors of the ABL tyrosine kinase activity of the fusion protein BCR-ABL have revolutionized the treatment of Philadelphia chromosome-positive (Ph) ALL [4,5]. TKIs are now integral components of therapy for Ph ALL.

(2015) 4(1), 5–8 The chronic myeloproliferative neoplasms (MPN), polycythemia vera (PV), essential thrombocytosis (ET) and primary myelofibrosis (PMF) are a unique group of hematopoietic stem cell disorders, characterized by the increased production of morphologically normal red cells, white cells and platelets alone or in combination and a tendency to develop myelofibrosis, extramedullary hematopoiesis with bone marrow failure or leukemic transformation, albeit at varying frequencies. These shared clinical features not only result in phenotypic mimicry among these three disorders but also between them, their companion myeloid neoplasms (MN) and certain benign disorders of hematopoiesis as well. In this regard, although they are clonal stem cell disorders, the chronic MPN differ from their companion MN because with supportive therapy alone, survival in PV, ET and PMF is usually measured not in years but decades. This makes diagnostic accuracy essential. However, until the 2005 discovery of a mutation (V617F) in JAK2 [1], a tyrosine kinase essential for hematopoietic progenitor cell proliferation and differentiation, the diagnosis of a specific MPN was largely based on clinical phenotype and, in particular exclusion of absolute erythrocytosis [2], the hall mark of PV, the most common MPN and the one in which the risk of thrombosis or hemorrhage is greatest. The development of a clinical assay for JAK2 V617F and subsequently, for mutations in JAK2 exon 12, redefined the MPN on a molecular basis with approximately 95% of PV patients expressing JAK2 V617F and 3% expressing JAK2 exon 12 mutations. By contrast, only 50–60% of ET and PMF patients expressed JAK2 V617F; the discovery of MPL mutations primarily in 4% of ET and 8% of PMF patients still left approximately 30–40% of MPN patients, including some with PV, without an identified molecular basis for their disease. In 2007, taking advantage of these molecular findings, the WHO proposed new diagnostic criteria for the MPN, relying on the use of molecular assays for JAK2 and MPL mutations together with stipulated values for the hemoglobin or hematocrit value, the use of the serum erythropoietin (EPO) level, endogenous erythroid colony formation, bone marrow histology, cytogenetics and flow cytometry","PeriodicalId":14166,"journal":{"name":"International Journal of Hematologic Oncology","volume":"4 1","pages":"5-8"},"PeriodicalIF":0.0,"publicationDate":"2015-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2217/IJH.15.2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68221463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, this concept is associated to a certain cost, with not always predictable mid- and long-term adverse events along with the economic cost accompanying these events.
