UNLABELLED Gene expression studies have consistently identified a HOXA-overexpressing cluster of T-cell acute lymphoblastic leukemias, but it is unclear whether these constitute a homogeneous clinical entity, and the biological consequences of HOXA overexpression have not been systematically examined. We characterized the biology and outcome of 55 HOXA-positive cases among 209 patients with adu...
The 2',3'-dideoxy analogues of cytidine, guanosine, adenosine, inosine, and thymidine have been compared for their cytostatic effects on 14 cell lines that include B lymphoblastic, T lymphoblastic, and myeloblastic lines. In all cases 2',3'-dideoxycytidine (ddCyd) was the most toxic nucleoside, with dideoxyguanosine (ddGuo) next, and little cytostatic action by the analogues of thymidine, adeno...
BACKGROUND Recently, in genome-wide analyses of DNA copy number abnormalities using single nucleotide polymorphism microarrays, genetic alterations targeting PAX5 were identified in over 30% of pediatric patients with acute lymphoblastic leukemia. So far the occurrence of PAX5 alterations and their clinical correlation have not been investigated in adults with BCR-ABL1-positive acute lymphoblas...
In the European Intergroup EURO-LB02 trial, children and adolescents with lymphoblastic lymphoma underwent the non-Hodgkin lymphoma Berlin-Frankfurt-Münster protocol without prophylactic cranial radiotherapy. The primary aims of this trial were to test whether replacing prednisone with dexamethasone during induction increases event-free survival in the subgroups with T-cell lymphoblastic lympho...
OBJECTIVE Cognitive impairments had been reported in childhood acute lymphoblastic leukemia, what caused the impairments needed to be demonstrated, chemotherapy-related or the disease itself. The primary aim of this exploratory investigation was to determine if there were changes in brain function of children with acute lymphoblastic leukemia before chemotherapy. METHODS In this study, we adv...
BACKGROUND Allogeneic hematopoietic cell transplantation is a potentially curative treatment for patients with acute lymphoblastic leukemia. However, the majority of older adults with acute lymphoblastic leukemia are not candidates for myeloablative conditioning regimens. A non-myeloablative preparative regimen is a reasonable treatment option for this group. We sought to determine the outcome ...
Acute lymphoblastic leukemia (ALL) constitute a family of genetically heterogeneous lymphoid neoplasms derived from B- and T-lymphoid progenitors. ALL affects both children and adults. Diagnosis is based on morphologic, immunophenotypic, and genetic features that allow differentiation from normal progenitors and other hematopoietic and nonhematopoietic neoplasms. The aim of this study was to in...
Genetic studies in T-cell acute lymphoblastic leukemia have uncovered a remarkable complexity of oncogenic and loss-of-function mutations. Amongst this plethora of genetic changes, NOTCH1 activating mutations stand out as the most frequently occurring genetic defect, identified in more than 50% of T-cell acute lymphoblastic leukemias, supporting a role as an essential driver for this gene in T-...
Detection of CD10, CD34 and their combined expression on Childhood Acute Lymphoblastic Leukemia and the association with clinical outcome in Indonesia 85 Detection of CD10, CD34 and their combined expression on Childhood Acute Lymphoblastic Leukemia and the association with clinical outcome in Indonesia CD10 and CD34 are surface markers that have been reported to have prognostic relevance in ch...
Circulating antibody to endotoxin core glycolipid and total serum immunoglobulin concentrations were measured in 86 children with cancer (54 with acute lymphoblastic leukaemia, four with acute myeloid leukaemia, and 28 with various solid tumours). Measurements were made before treatment in the group with acute lymphoblastic leukaemia as well as when patients were both on and off chemotherapy. I...
