Purpose Children with acute lymphoblastic leukemia (ALL) are generally instructed to take mercaptopurine (6-MP) in the evening and without food or dairy products. This study examines the association between 6-MP ingestion habits and 6-MP adherence, red cell thioguanine nucleotide (TGN) levels, and risk of relapse in children with TMPT wild-type genotype. Methods Participants included 441 children with ALL receiving oral 6-MP for maintenance. Adherence was monitored over 48,086 patient-days using the Medication Event Monitoring System; nonadherence was defined as adherence rate < 95%...

BACKGROUND: We sought to determine whether adolescents with metastatic alveolar rhabdomyosarcoma (ARMS) or embryonal RMS (ERMS) had a different event-free survival (EFS) compared with younger patients, and to identify treatment-related factors (adverse events, AEs) that may be associated with differences in outcome. METHODS: The prevalence of AEs in adolescents older than 13 years was compared with that in patients less than or equal to 13 years of age (Fisher exact test) in patients enrolled onto ARST0431...

Germ cell tumors (GCT) are a rare form of childhood cancer that originate from the primordial germ cell. Recent genome-wide association studies (GWAS) have identified susceptibility alleles for adult testicular GCT (TGCT). We test whether these SNPs are associated with GCT in pediatric and adolescent populations. This case-parent triad study includes individuals with GCT diagnosed between ages 0-19. We evaluated 26 SNPs from GWAS of adult TGCT and estimated main effects for pediatric GCT within complete trios (N=366) using the transmission disequilibrium test...

The phosphatidylinositol 3-kinase (PI3K)/mammalian (or mechanistic) target of rapamycin (mTOR) signalling pathway is commonly dysregulated in acute lymphoblastic leukaemia (ALL). A phase 1 trial of the mTOR inhibitor temsirolimus in combination with UKALL R3 re-induction chemotherapy was conducted in children and adolescents with second or greater relapse of ALL. The initial temsirolimus dose level (DL1) was 10 mg/m(2) weekly × 3 doses. Subsequent patient cohorts received temsirolimus 7·5 mg/m(2) weekly × 3 doses (DL0) or, secondary to toxicity, 7·5 mg/m(2) weekly × 2 doses (DL-1)...

INTRODUCTION: A high cure rate for Wilms' tumor has been achieved using a multidisciplinary approach. The natural step forward is to offer the benefits of a minimally invasive technique for surgery, which is an obligatory part of treatment. Nevertheless, some authors resist using videolaparoscopic radical nephrectomy (VRN) because of concerns about reducing the cure index. METHODS: The present study included children with unilateral Wilms' tumor treated from December 2003 to December 2015 with neoadjuvant chemotherapy followed by VRN...

INTRODUCTION: Cancer is the leading cause of death between the first year of life and adolescence, and some types of diseases are still a major challenge in terms of cure. There is, therefore, a major need for new drugs. Recent findings in cancer biology open the door to the development of targeted therapies against individual molecular changes, as well as immunotherapy. Promising results in adult anti-cancer drug development have not yet been translated into paediatric clinical practice...

Little is known about the etiology of hepatoblastoma. We aimed to confirm the results of a previous study evaluating the association between parental occupational exposures and hepatoblastoma. In our case-control study, we identified cases (n=383) from the Children's Oncology Group and controls from birth certificates (n=387), which were frequency matched to cases on year and region of birth, sex, and birth weight. Occupational exposure in the year before and during the index pregnancy was collected through maternal interview and analyzed using unconditional logistic regression...

BACKGROUND: Adolescents and young adults (AYAs) ages 15 to 39 years with cancer continue to experience disparate survival outcomes compared with their younger and older counterparts. This may be caused in part by differential access to specialized cancer centers (SCCs), because treatment at SCCs has been associated with improved overall survival. The authors examined social and clinical factors associated with AYA use of SCCs (defined as Children's Oncology Group-designated or National Cancer Institute-designated centers)...

The practice of nuclear medicine in children is well established for imaging practically all physiologic systems but particularly in the fields of oncology, neurology, urology, and orthopedics. Pediatric nuclear medicine yields images of physiologic and molecular processes that can provide essential diagnostic information to the clinician. However, nuclear medicine involves the administration of radiopharmaceuticals that expose the patient to ionizing radiation and children are thought to be at a higher risk for adverse effects from radiation exposure than adults...
