Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL) is a newly identified high-risk (HR) B-lineage ALL subtype, accounting for ∼15% of children with National Cancer Institute-defined HR B-ALL. It occurs more frequently in adolescents and adults, having been reported in as much as 27% of young adults with ALL between 21 and 39 years of age. It exhibits adverse clinical features, confers a poor prognosis, and harbors a diverse range of genetic alterations that activate cytokine receptor genes and kinase signaling pathways, making it amenable to treatment with tyrosine kinase inhibitor (TKI) therapy...

Prognostic factors determined at diagnosis are predictive for outcome whereas achievement of morphological complete remission (CR) is still an important end point during treatment. Residual disease after therapy may reflect the sum of all diagnosis and postdiagnosis resistance mechanisms/factors; its measurement could hypothetically be very instrumental for guiding treatment. The possibility of defining residual disease (minimal residual disease [MRD]) far below the level of 5% blast cells is changing the landscape of risk classification...

Acute myeloid leukemia (AML) is a disease of the elderly, but less than half of these patients are offered therapy despite the evidence of better survival with treatment in this patient population. Assessing fit, vulnerable, and frail older adults with AML remains a challenge for the treating oncologist. A majority of AML patients are elderly and often have significant comorbidities, lack of social support, and older caregivers. Performance status (PS), a subjective measure of how a patient will tolerate cancer chemotherapy, has been strongly correlated with mortality in older AML patients...

Acute promyelocytic leukemia (APL) is a unique subtype of acute myeloid leukemia (AML), which presents with a distinct coagulopathy. Therapeutic advances have made APL one of the true success stories in oncology, transforming this once lethal disease into the most curable form of AML. For many patients, cure will now be achieved without the use of chemotherapy. It is hoped that limiting chemotherapy will reduce mortality even further, particularly among more vulnerable older adults whose survival lagged behind that of younger patients...

Acute myelogenous leukemia (AML) is an aggressive disease associated with drug resistance and relapse. To improve therapeutic strategies, it is critical to better understand the mechanisms that underlie AML progression. Here we show that the integrin binding glycoprotein CD98 plays a central role in AML. CD98 promotes AML propagation and lethality by driving engagement of leukemia cells with their microenvironment and maintaining leukemic stem cells. Further, delivery of a humanized anti-CD98 antibody blocks growth of patient-derived AML, highlighting the importance of this pathway in human disease...

BACKGROUND: Autologous stem cell transplantation (ASCT) for adult acute myelogenous leukemia (AML) is a valid therapeutic option for patients with good-risk and intermediate-risk disease. The authors used the registry of the European Society for Blood and Marrow Transplantation to compare combined busulfan and melphalan (BUMEL) with combined busulfan and cyclophosphamide (BUCY) before transplantation. METHODS: From 2005 to 2013, 853 patients with available cytogenetics underwent ASCT in first remission, including 257 after receiving BUMEL and 596 after receiving BUCY...

Mutations in TET2, encoding one of the TET members responsible for the conversion of DNA cytosine methylation to hydroxymethylation (5-hmc), have been recently described in Human T-lymphotropic virus type 1-associated adult T-cell leukemia/lymphoma (ATLL). However, neither the amount of genomic 5-hmc in ATLL tumor cells nor TET2 expression has been studied yet. In this study, we analyzed these two parameters as well as the mutational status of TET2 in ATLL patients. By employing a direct in situ approach, we documented that tumor T cells infiltrating lymph nodes exhibit low level of 5-hmc compared to residual normal T cells...

Hypodiploidy <40 chromosomes is an uncommon genetic feature of acute lymphoblastic leukemia (ALL) in both children and adults. It has long been clear by cytogenetic analyses, and recently confirmed by mutational profiling, that these cases may be further subdivided into two subtypes: near-haploid ALL with 24-30 chromosomes and low hypodiploid ALL with 31-39 chromosomes. Both groups are associated with a very poor prognosis and these patients are among those who could benefit most from novel treatments.

A 72-year-old man was diagnosed with acute myeloid leukemia and advanced esophageal cancer(cT3N3M1, clinical Stage IV, high-moderately differentiated squamous cell carcinoma). He was started on remission induction chemotherapy and postremission therapy provided according to the Japan Adult Leukemia Study Group's AML201 protocols. His acute myeloid leukemia showed a complete response. After that, he was administered radiotherapy for esophageal cancer and showed a partial response. One year after treatment, he developed a local recurrence of esophageal cancer...

The first edition of the European LeukemiaNet (ELN) recommendations for diagnosis and management of acute myeloid leukemia (AML) in adults published in 2010 has found broad acceptance by physicians and investigators caring for patients with AML. Recent advances, for example, in the discovery of the genomic landscape of the disease, in the development of assays for genetic testing and for detecting minimal residual disease, as well as in the development of novel anti-leukemic agents, prompted an international panel to provide updated evidence- and expert opinion-based recommendations...

Background: In the last decade, it has become clear that change of gene expression may alter the hematopoietic cell quiescent state and consequently play a major role in leukemogenesis. WT1 is known to be a player in acute myeloid leukemia (AML) and FOXP3 has a crucial role in regulating the immune response. Objectives: To evaluate the impact of overexpression of WT1and FOXP3 genes on clinical course in adult and pediatric AML patients in Egypt. Patients and methods: Bone marrow and peripheral blood samples were obtained from 97 de novo non M3 AML patients (63 adult and 34 pediatric)...

Acute Leukemia is one of the common haematological malignancies encountered with varied clinical and haematological presentation. In acute leukaemia, complications like bleeding and infection cause significant morbidity and mortality, thus overshadowing the thromboembolic events. Among the various malignant haematological disorders, the association of thromboembolic events is often noted with acute promyelocytic leukemia, though the overall frequency of such events remains very low. Acute Lymphoblastic Leukemia (ALL) is, however, more common than Acute non-lymphoblastic Leukaemia...

Frederick R Appelbaum
Whether patients with acute myeloid leukemia (AML) should receive routine consolidation chemotherapy prior to transplant remains a significant question. Consolidation therapy may be advisable in the face of transplant delays, such as donor identification, insurance clearance, or transplant center scheduling, to prevent relapse prior to transplant. However, in cases where physicians have a choice, the question of the value of consolidation chemotherapy continues to be debated. This paper reviews the value of consolidation therapy in 4 different transplant settings...

A high relapse rate for patients with acute myeloid leukemia (AML) is still a major barrier to the long-term survival of these patients. Nevertheless, considerable progress has been made both in the biology and therapy of the disease. Specifically, progress has been made in the areas of integrated genomic analysis for prognosis, the widening application of minimal residual disease (MRD) monitoring in clinical practice, the development of new agents, and the increasing use of drugs, such as IDH and FLT3 inhibitors, as a bridge to transplant...

BACKGROUND: Childhood acute lymphoblastic leukemia (ALL) survivors have increased risk of obesity, metabolic alterations and cardiovascular disease (CVD). Vascular endothelial function has been studied in adult cancers. Limited data exist regarding CVD risk factors among childhood ALL survivors. We aimed to assess endothelial function, metabolic and cardiovascular risk factors in young survivors of childhood ALL. METHODS: Auxological parameters, blood pressure, glucose, lipid profile, hemostatic markers (total adiponectin and high-molecular-weight subfraction, endothelin-1, von Willebrand factor antigen, thrombin-antithrombin complex, D-dimers, fibrinogen), high sensitive C-reactive protein and ultrasound parameters of endothelial function (flow-mediated dilation-FMD, common carotid intima-media thickness-C-IMT, and antero-posterior diameter of infra-renal abdominal aorta-APAO) were assessed in 52 ALL survivors and 34 sex and age-matched controls...

Chemoresistance represents a major challenge for treatment of acute lymphoblastic leukemia (ALL). Thus, new drugs to overcome chemoresistance in ALL are urgently needed. To this end, we established a cytarabine (araC)-resistant ALL cell line (NALM-6/R), which interestingly displayed cross-resistance towards doxorubicin (ADM). Here we report that low dose of triptolide (TPL), a natural product used for treating inflammatory diseases such as arthritis, could reverse araC and ADM resistance and in NALM-6/R cells as well as primary cells from patients with relapsed or refractory (R/R) ALL, reflected by inhibition of cell proliferation and induction of apoptosis in vitro, and repression of tumor growth in vivo in a mouse xenograft model...

Haploidentical stem cell transplantation (SCT) is increasingly used to treat pediatric patients with malignant or non-malignant hematological disorders. The CD34+ dose of bone marrow or peripheral blood stem cells (PBSCs) has been shown to be an important determinant of the transplant outcome in adults under various preparative regimens. However, knowledge of the effect of the CD34+ dose in pediatric haploidentical SCT is limited. We analyzed the data of 348 pediatric patients (aged 2-18 years) with acute or chronic leukemia, myelodysplastic syndrome (MDS), and other hematological disorders that received a transplant between 2002 and 2012...
