Adolescents with cancer may demonstrate problems in their self-esteem and schooling. This study aims to screen the preadolescents and adolescents more at risk in their self-esteem perception and schooling difficulties post-five years from the end of therapy. Twenty-five paediatric ex-patients healed from leukaemia were recruited at the Haematology-Oncologic Clinic (University of Padua). The mean age of the children was 13.64 years (Standard Deviation (SD)) = 3.08, range = 10-19 years), most were treated for acute lymphoblastic leukaemia (ALL) (84%) and relatively equally distributed by gender...

OBJECTIVE: We explored parents' accounts of the parent-clinician relationship in childhood cancer to understand how parents who perceive threats to the relationship can be supported. METHODS: Multi-centre longitudinal qualitative study, with 67 UK parents of children (aged 1-12 years) receiving treatment for acute lymphoblastic leukaemia. Analyses drew on the wider sample but focussed on 50 semi-structured interviews with 20 parents and were informed by constant comparison...

Acute lymphoblastic leukaemia (ALL) is rarely seen in pregnancy. Massive hepatosplenomegaly as a presentation of ALL has not been described previously in any patient population. A 30-year-old pregnant woman presented at 16 weeks' gestation with epistaxis, jaundice, diffuse abdominal pain and distension, massive hepatosplenomegaly and peripheral oedema. On the basis of blood tests, bone marrow biopsy and imaging, a diagnosis of ALL complicated by massive hepatosplenomegaly with splenic infarctions was made. The patient was referred to oncology for appropriate chemotherapy...

The RUNX1 transcription factor is a critical regulator of normal haematopoiesis and its functional disruption by point mutations, deletions or translocations is a major causative factor leading to leukaemia. In the majority of cases, genetic changes in RUNX1 are linked to loss of function classifying it broadly as a tumour suppressor. Despite this, several recent studies have reported the need for a certain level of active RUNX1 for the maintenance and propagation of acute myeloid leukaemia and acute lymphoblastic leukaemia cells, suggesting an oncosupportive role of RUNX1...

High frequencies of blasts in primary acute lymphoblastic leukaemia (ALL) samples have the potential to induce leukaemia and to engraft mice. However it is unclear how individual ALL cells each contribute to drive leukaemic development in a bulk transplant and the extent to which these blasts vary functionally. We used cellular barcoding as a fate mapping tool to track primograft ALL blasts in vivo. Our results show that high numbers of ALL founder cells contribute at similar frequencies to leukaemic propagation over serial transplants, without any clear evidence of clonal succession...

The understanding of leukemogenesis in early-age acute leukemia (EAL) has improved remarkably. Initiating somatic mutations detected in dried neonatal blood spots (DNBS) and in cord blood samples of affected children with leukemia have been proven to be acquired prenatally. However, to date, few epidemiological studies have been carried out exploring EAL that include infants and children 13-24 months of age at the diagnosis. Maternal exposure to transplacental DNA-damaging substances during pregnancy has been suggested to be a risk factor for EAL...

OBJECTIVE: Very little is known about histological aspects of paediatric scars and the possible role of the immune system during their formation. In this study, the histology thoracic scars caused by the placement of an implantable central venous access device in children who underwent treatment for cancer was assessed. METHOD: The amount and type of collagen, the collagen orientation, the type of elastic fibres, the vascularsation, and the count of neutrophils, macrophages, and lymphocytes were analysed...

BACKGROUND: Health-related quality of life (HRQoL) from diagnosis until end of treatment for children with acute lymphoblastic leukaemia was investigated, examining effects of age, gender, risk-stratified treatment regimen, and therapy intensity (one vs. two 'delayed intensifications' [DIs]). METHOD: In a multi-centre prospective study, parents reported their child's generic and disease-specific HRQoL and their own care-giving burden at five time points. From 1,428 eligible patients, 874 parents completed questionnaires at least once during treatment...

PURPOSE OF REVIEW: Loss of IKAROS in committed B cell precursors causes a block in differentiation while at the same time augments aberrant cellular properties, such as bone marrow stromal adhesion, self-renewal and resistance to glucocorticoid-mediated cell death. B cell acute lymphoblastic leukaemias originating from these early stages of B cell differentiation and associated with IKAROS mutations share a high-risk cellular phenotype suggesting that deregulation of IKAROS-based mechanisms cause a highly malignant disease process...

BACKGROUND: Leukaemia remains the most common type of paediatric cancer and its aetiology remains unknown, but considered to be multifactorial. It is suggested that the initiation in utero by relevant exposures and/or inherited genetic variants and, other promotional postnatal exposures are probably required to develop leukaemia. This study aimed to map the incidence and analyse possible clusters in the geographical distribution of childhood acute leukaemia during the critical periods and to evaluate the factors that may be involved in the aetiology by conducting community and individual risk assessments...

OBJECTIVES: CREBBP alterations are associated with many diseases including leukaemia. However, CREBBP expression and its clinical relevance in paediatric acute lymphoblastic leukaemia have not been elucidated. METHODS: We studied CREBBP mRNA expression in 349 patients treated with either the BCH-2003 or CCLG-2008 protocol. Using a receiver operating characteristic curve, patients were divided into low- or high-CREBBP. The association among clinicobiological characteristics, outcomes, and CREBBP level was analysed...

Copy number aberrations (CNAs) represent cooperating events in B-lineage acute lymphoblastic leukaemia (B-ALL); however, their clinical relevance across different age cohorts is unclear. We analysed the recurrent CNAs in 157 age-stratified B-ALL negative cases for recurrent rearrangements (B-NEG ALL), and their association with patients' clinico-biological features. We found that: (i) CDKN2A/RB1-deleted and EBF1-deleted adults had a shorter disease-free survival than those with wild-type, (ii) among the unfavourable markers, CDKN2A/RB1 deletions and K/NRAS mutations retained their impact in multivariate analysis, encouraging the evaluation of CDKN2A/RB1 deletions and RAS mutations in the diagnostic/prognostic workflow to refine ALL risk assessment...

The efficacy of high-dose cytarabine (HDCA) plus cyclophosphamide/total-body irradiation (CY/TBI) has been proved in cord blood transplantation (CBT) for acute lymphoblastic leukaemia (ALL), but not in bone marrow or peripheral blood stem cell transplantation (BMT/PBSCT). In this cohort study, we compared the prognosis of CY/TBI (N = 1244) and HDCA/CY/TBI (N = 316) regimens in BMT/PBSCT for ALL. The addition of HDCA decreased post-transplant relapse, while significantly increasing non-relapse mortality (risk ratio, 1·33), and overall survival was not improved...

Background: It has been proposed that childhood vaccinations protect against acute lymphoblastic leukaemia (ALL) in children by modulation of future responses to common infections in childhood. However, the available studies provide inconsistent findings, and population-based cohort studies with longitudinal information on vaccinations are lacking. Methods: In a register-based cohort of all children born in Denmark from 1 January 1990 to 31 December 2008, followed up until age 15 years or 31 December 2009 ( n  = 1 225 404), we evaluated exposure to childhood vaccination and risk of childhood ALL, including information on ALL subtypes...

Flow cytometric detection of minimal residual disease (MRD) in children with B-cell precursor acute lymphoblastic leukaemia (BCP-ALL) requires immunophenotypic discrimination between residual leukaemic cells and B-cell precursors (BCPs) which regenerate during therapy intervals. In this study, EuroFlow-based 8-colour flow cytometry and innovative analysis tools were used to first characterize the immunophenotypic maturation of normal BCPs in bone marrow (BM) from healthy children, resulting in a continuous multiparametric pathway including transition stages...

BACKGROUND: Global inequalities in access to health care are reflected in differences in cancer survival. The CONCORD programme was designed to assess worldwide differences and trends in population-based cancer survival. In this population-based study, we aimed to estimate survival inequalities globally for several subtypes of childhood leukaemia. METHODS: Cancer registries participating in CONCORD were asked to submit tumour registrations for all children aged 0-14 years who were diagnosed with leukaemia between Jan 1, 1995, and Dec 31, 2009, and followed up until Dec 31, 2009...

Our goals are to (1) set forth and defend a multiprinciple system for selecting individuals who meet trial eligibility criteria to participate in early phase clinical trials testing chimeric antigen receptor (CAR T-cell) for acute lymphoblastic leukaemia when demand for participation exceeds spaces available in a trial; (2) show the relevance of these selection criteria to other breakthrough experimental therapies; (3) argue that distinct distributive justice criteria apply to breakthrough experimental therapies, standard research and healthcare and (4) argue that as evidence of benefit increases, the emphasis of justice in research shifts from protecting subjects from harm to ensuring fair access to benefits...

PURPOSE: Central nervous system (CNS) prophylaxis in the treatment of childhood acute lymphoblastic leukaemia (ALL) is routinely achieved through intrathecal chemotherapy (ITC). The presence of high level language deficits in older children who received CNS-directed ITC for ALL in early childhood is yet to be elucidated, with previous research suggesting that high level language deficits may appear later in ALL survivors' development at an age when these skills typically emerge. METHOD: A test battery covering foundational language skills and higher-order language skills was administered to five participants (aged 10-15 years) with a history of ITC for ALL...
