OBJECTIVE: Most children with cancer are diagnosed in early childhood, potentially resulting in missed developmental opportunities. The most common diagnoses-brain tumors, leukemia-are also associated with increased risk of neurocognitive deficits. Unfortunately, research regarding the functioning of preschool-aged children with cancer is limited. Our objective is to describe the cognitive and psychosocial functioning of preschool-aged children with cancer who completed a clinical evaluation at a hospital-based psychology clinic...

Refusing treatment for potentially curable childhood cancers engenders much discussion and debate. I present a case in which the competent parents of a young Amish child with acute myeloid leukemia deferred authority for decision making to the child's maternal grandfather, who was vocal in his opposition to treatment. I analyze three related concerns that distinguish this case from other accounts of refused treatment. First, I place deference to grandparents as decision makers in the context of surrogate decision making more generally...

BACKGROUND: Botulism is a potentially fatal infection characterized by progressive muscle weakness, bulbar paralysis, constipation and other autonomic dysfunctions. A recent report suggested that cancer chemotherapy might increase the risk for the intestinal toxemia botulism in both adults and children. CASE PRESENTATION: We report a 5-year-old boy, who developed general muscle weakness, constipation, ptosis and mydriasis during the third induction therapy for relapsed acute myeloid leukemia...

OBJECTIVES: Recent guidelines recommend to assess emotional distress in pediatric oncology during treatment and in after care. One tool used to do this is the distress thermometer (DT), a simple tool which has almost exclusively been studied in its screening abilities. Given its increased used as a measure of distress per se, it is necessary to document its concurrent validity. The goal of this study was to identify clinical domains (eg, depression, anxiety) and individual symptoms associated with pediatric cancer survivors' rating on the DT...

BACKGROUND: Donor cell leukemia (DCL) occurs after allogeneic hematopoietic stem cell transplantation. Several mechanisms, including occult leukemic/preleukemic subclones in the donor graft and germline predisposition to leukemia, are proposed to be associated with DCL's molecular pathogenesis. We report a comprehensive genetic analysis of a patient with KMT2A-rearranged DCL after allogeneic bone marrow transplantation for refractory cytopenia of childhood. PROCEDURE: We performed a whole-exome sequencing of the recipient's peripheral blood before transplant and the donor's peripheral blood and the recipient's bone marrow at the time of DCL diagnosis...

BACKGROUND: We sought to examine the relationship between child specific health aid (CHA) and burden of disease. Based on existing evidence, we hypothesized that foreign aid for child health would not be proportional to burden of disease. METHODS: In order to examine CHA and burden of disease, we obtained estimates of these parameters from established sources. Estimates of disability adjusted life years (DALYs) in children (0-5 years) were obtained from the World Health Organization for 2000 and 2012...

Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy and a leading cause of death due to disease in children. The genetic basis of ALL susceptibility has been supported by its association with certain congenital disorders and, more recently, by several genome-wide association studies (GWAS). These GWAS identified common variants in ARID5B, IKZF1, CEBPE, CDKN2A, PIP4K2A, LHPP and ELK3 influencing ALL risk. However, the risk variants of these SNPs were not validated in all populations, suggesting that some of the loci could be population specific...

Neuroblastoma is the most common extracranial malignancy of childhood. Patients with high-risk disease receive multimodal treatment including chemotherapy combinations containing alkylating agents and topoisomerase inhibitors with potential for inducing therapy-related malignancy later in life. Most commonly, cytogenetic changes of pediatric therapy-related myelodysplastic syndrome/acute myeloid leukemia involve chromosome 5 or 7. Here we report a novel case of therapy-related myelodysplastic syndrome/acute myeloid leukemia 30 months after treatment for high-risk neuroblastoma with biphenotypic cell surface markers and a not yet described translocation t(1;6)(q25;p23)...

6-Mercaptopurine (6-MP) is one of the main components for the treatment of childhood acute lymphoblastic leukemia (ALL). However, many patients require a dose reduction of 6-MP due to its severe toxicities. NUDT15 variants are one of the factors that cause 6-MP intolerability in Asians. In each patient with heterozygous variants of NUDT15, 6-MP intolerability differs. Therefore, we hypothesized that the combination of NUDT15 genotype with ABCC4 genotype, which is associated with 6-MP efflux, might enable to accurately predict 6-MP intolerability...

BACKGROUND: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is very rarely diagnosed in children with less than 50 cases in the literature. OBSERVATION: We report a case of childhood BPDCN who mimicked acute rheumatic fever at presentation. Majority of the reported childhood BPDCN received acute lymphoblastic leukemia-like chemotherapy with/without stem cell therapy, whereas those who received acute myeloid leukemia-like therapy predominantly succumbed to disease or sepsis...

Congenital amegakaryocytic thrombocytopenia (CAMT, MIM# 604498) is a rare congenital bone marrow failure syndrome which presents early in life with abnormal bleeding because of thrombocytopenia. Classically, megakaryocytes are decreased to absent in the bone marrow. The development of aplastic anemia early in childhood has led to the recommendation for early stem cell transplantation. Quantitative or loss-of-function mutations in the myeloproliferative leukemia gene (c-mpl), whose gene product functions as the thrombopoietin receptor, have been identified as causative for CAMT...

BACKGROUND: Parental occupational and childhood exposures to farm animals have been positively associated with childhood brain tumors, whereas associations with childhood leukemia are equivocal. The developing immune system may be influenced by allergen, virus, or other exposures from animal sources, which may contribute to childhood cancer incidence. METHODS: Incident cancers (acute lymphoblastic leukemia [ALL], acute myeloid leukemia [AML], central nervous system [CNS], peripheral nervous system [PNS]) for children aged 0-4 diagnosed between 2003 and 2008 were obtained from nine National Cancer Institute Surveillance, Epidemiology and End Results (SEER) registries and were linked to U...

BACKGROUND: Neoepitopes derived from tumor-specific somatic mutations are promising targets for immunotherapy in childhood cancers. However, the potential for such therapies in targeting these epitopes remains uncertain due to a lack of knowledge of the neoepitope landscape in childhood cancer. Studies to date have focused primarily on missense mutations without exploring gene fusions, which are a major class of oncogenic drivers in pediatric cancer. METHODS: We developed an analytical workflow for identification of putative neoepitopes based on somatic missense mutations and gene fusions using whole-genome sequencing data...

PURPOSE: Many adult survivors of childhood cancer are at high-risk of developing cardiovascular disease. Cancer therapy may cause damage to the vascular endothelium, thereby initiating atherosclerosis. Atorvastatin has been shown to improve endothelial function independent of reducing cholesterol, as well as reduce/slow arterial stiffness and thickening, yet has never been studied in childhood cancer survivors (CCS). METHODS: Twenty-seven young adult (age 26.8 ± 6...
