PURPOSE: We evaluated the satisfaction of adult survivors of childhood cancers and their general practitioners (GP) after a long-term consultation. METHODS: The first Long-term Follow-up Study in Oncology (SALTO1) is a prospective cohort study of survivors of childhood cancers (except leukemia) diagnosed between 1987 and 1992 in the Rhône-Alpes and Auvergne regions of France. Of the 481 patients eligible for the study, 150 participated in a long-term consultation with a pediatric oncologist and an internist, after which survivors and their GPs received long-term plans and recommendations based on consultation findings...

Little is known about cancer incidence among children and youths in Japan. We aimed to describe cancer incidence in Japan focusing on childhood, adolescence and young adulthood (AYA). Cancer incidence data were obtained from the Monitoring of Cancer Incidence in Japan project. For the 2009-2011 incidence, the data were collected from 40 prefectures, of which data from 27 prefectures meeting quality standards were analyzed (population coverage: 38.6%). Cancers diagnosed in 0-39 years of age were classified according to the International Classification of Childhood Cancer (version 3)...

The prevalence of obesity and related comorbidities in survivors of childhood acute lymphoblastic leukemia (ALL) is well established and ranges anywhere from 29% to 69% depending on the study. We sought to explore the awareness of parents of survivors of childhood ALL regarding the increased risk of obesity and their perceptions regarding the overall health of their child. One hundred twenty-one parents of 99 survivors of pediatric ALL completed surveys regarding perceptions of obesity risk in survivors. Eighty percent of parents of overweight and obese survivors correctly identified their child as "a little overweight" or "overweight...

Purpose Childhood cancer survivors (CCSs) are at increased risk for subsequent malignant neoplasms (SMNs). We evaluated the long-term risk of SMNs in a well-characterized cohort of 5-year CCSs, with a particular focus on individual chemotherapeutic agents and solid cancer risk. Methods The Dutch Childhood Cancer Oncology Group-Long-Term Effects After Childhood Cancer cohort includes 6,165 5-year CCSs diagnosed between 1963 and 2001 in the Netherlands. SMNs were identified by linkages with the Netherlands Cancer Registry, the Dutch Pathology Registry, and medical chart review...

Killer immunoglobulin-like receptors (KIRs) have the ability to regulate Natural killer (NK) cell function through inhibition/activation mechanisms. Healthy human cells express HLA class I ligands on their surface, which are recognized by NK cells to avoid spontaneous cell destruction. The associations of KIRs and/or HLA class 1 ligands in leukemic patients have been studied in some populations, with some of these studies demonstrating an association of specific types with leukemia. KIRs and their corresponding HLA class 1 ligands were investigated in Saudi patients with ALL and AML and compared to healthy controls...

High-dose methotrexate (HDMTX) plays an important role in the treatment of acute lymphoblastic leukemia (ALL) although there is great inter-patient variability in the efficacy and toxicity of MTX. The relationship between polymorphisms in genes encoding MTX transporters and MTX response is controversial. In the present study, 322 Chinese children with standard- and intermediate-risk ALL were genotyped for 12 polymorphisms. SLCO1B1 rs10841753 showed a significant association with plasma MTX levels at 48 h (P = 0...

Biological effects of static magnetic fields (MF) and time-varying MF of electricity (50/60 Hz) appear possible from intensities in the low illitesla range. However, prolonged exposure to 50/60 Hz MF is associated with an increased risk of childhood leukemia at less than one microtesla of time-averaged intensity. And such kind of association is suggested in adults for some blood cancers and senile dementia. The cryptochrome hypothesis has been proposed to explain the association established with childhood leukemia...

Previously we identified B-cell lineage leukemic lymphoblasts as a new expression site for subunit A of blood coagulation factor XIII (FXIII-A). On the basis of FXIII-A expression, various subgroups of B-cell precursor acute lymphoblastic leukemia (BCP-ALL) can be identified. Fifty-five children with BCP-ALL were included in the study. Bone marrow samples were obtained by aspiration and the presence of FXIII-A was detected by flow cytometry. G-banding and fluorescent in situ hybridization was performed according to standard procedures...

REVIEW
Simone Bürgler, David Nadal
Precursor B acute lymphoblastic leukemia (BCP-ALL), the most common childhood malignancy, arises from an expansion of malignant B cell precursors in the bone marrow. Epidemiological studies suggest that infections or immune responses to infections may promote such an expansion and thus BCP-ALL development. Nevertheless, a specific pathogen responsible for this process has not been identified. BCP-ALL cells critically depend on interactions with the bone marrow microenvironment. The bone marrow is also home to memory T helper (Th) cells that have previously expanded during an immune response in the periphery...

Aberrations in epigenetic modifications contribute to leukemogenesis in childhood acute myeloid leukemia (AML). We combined DNA hypomethylating agent azacitidine with histone deacetylase inhibitor panobinostat in preclinical models of childhood AML. Synergistic cytotoxic effect upon treatment with azacitidine and panobinostat with combination indices <1.0 was observed. Azacitidine and panobinostat increased median survival by 26 and 6days respectively in MV4;11 xenografted mice. Mice treated with both drugs showed a drastic reduction in leukemic burden leading to complete remission sustained for the duration of the experimental period lasting more than 519days...

OBJECTIVE: Metabolic complications are frequent in childhood leukemia (ALL) survivors treated with cranial radiotherapy (CRT). These complications are potentially mediated by damage to the hypothalamus (HT), as childhood onset (CO) craniopharyngioma (CP) survivors without HT involvement are spared overt obesity. Diffusion tensor imaging (DTI) shows brain tissue microstructure alterations, by fractional anisotrophy (FA), mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD)...

BACKGROUND: The improved survival rates for childhood acute lymphoblastic leukemia (ALL) may be jeopardized by the development of a second cancer, which has been associated with thiopurine therapy. PROCEDURE: We retrospectively analyzed three sequential Nordic Society of Paediatric Haematology and Oncology's protocols characterized by increasing intensity of thiopurine-based maintenance therapy. We explored the risk of second cancer in relation to protocols, risk group, thiopurine methyltransferase (TPMT) activity, ALL high hyperdiploidy (HeH), and t(12;21)[ETV6/RUNX1]...

BACKGROUND: In the adult population with newly diagnosed chronic myeloid leukemia (CML), variant translocations are usually not considered to be impairing the prognosis, whereas some additional cytogenetic abnormalities (ACAs) are associated with a negative impact on survival. Because of the rarity of CML in the pediatric population, such abnormalities have not been investigated in a large group of children with CML. METHODS: The prognostic relevance of variant t(9;22) and ACAs at diagnosis was assessed in 301 children with CML in the chronic phase who were enrolled in the International Registry for Chronic Myeloid Leukemia in Children and Adolescents...

BACKGROUND: Venous thromboembolism (VTE) is a common and severe complication during treatment of acute lymphoblastic leukemia (ALL). An important cause is the intensive use of asparaginase. Prospective cohort studies in which prophylactic low-molecular-weight heparin (LMWH) was used to prevent VTE showed lower VTE risk than in historic control cohorts, with a negligible bleeding risk. However, the efficacy of thromboprophylaxis with LMWH during ALL treatment has never been investigated in a randomized design...

The locus CDKN2A/B (9p21.3), which comprises the tumor suppressors genes CDKN2A and CDKN2B and the long noncoding RNA (lncRNA) known as ANRIL (or CDKN2B-AS), was associated with childhood acute lymphoblastic leukemia (ALL) susceptibility in several genome wide association studies (GWAS). However, the variants associated in the diverse studies were different. Recently, new and independent SNPs deregulating the locus function were also identified in association with ALL risk. This diversity in the results may be explained because different variants in each population could alter CDKN2A/B locus function through diverse mechanisms...

B-cell precursor acute lymphocytic leukemia (B-ALL) represents a worldwide public health issue. Particularly, Mexico is one of the countries with the highest incidence of ALL in children. Between the multiple factors involved in ALL etiology, genetic alterations are clearly one of the most relevant features. In this work, a group of 24 B-ALL patients, all negative for the four most frequent gene fusions (ETV6-RUNX1, BCR-ABL1, TCF3-PBX1 and MLL-AF4), were included in a high-resolution microarray analysis in order to evaluate genomic copy-number alterations (CNAs)...

BACKGROUND: The association of childhood leukemia with traffic pollution was considered in a number of studies from 1989 onwards, with results not entirely consistent and little information regarding subtypes. AIM OF THE STUDY: We used the data of the Italian SETIL case-control on childhood leukemia to explore the risk by leukemia subtypes associated to exposure to vehicular traffic. METHODS: We included in the analyses 648 cases of childhood leukemia (565 Acute lymphoblastic-ALL and 80 Acute non lymphoblastic-AnLL) and 980 controls...
