PURPOSE Atypical teratoid rhabdoid tumor (ATRT) of the CNS is a highly malignant neoplasm primarily affecting young children, with a historic median survival ranging from 6 to 11 months. Based on a previous pilot series, a prospective multi-institutional trial was conducted for patients with newly diagnosed CNS ATRT. PATIENTS AND METHODS Treatment was(More)
Although mutations in the human doublecortin gene (DCX) cause profound defects in cortical neuronal migration, a genetic deletion of Dcx in mice produces a milder defect. A second locus, doublecortin-like kinase (Dclk), encodes a protein with similar "doublecortin domains" and microtubule stabilization properties that may compensate for Dcx. Here, we(More)
BACKGROUND The epidemiological, prognostic, and therapeutic features of child and adolescent meningioma are poorly defined. Clinical knowledge has been drawn from small case series and extrapolation from adult studies. This study was done to pool and analyse the clinical evidence on child and adolescent meningioma. METHODS Searches of PubMed, Medline, and(More)
PURPOSE To determine the event-free survival (EFS) and overall survival of children with average-risk medulloblastoma and treated with reduced-dose craniospinal radiotherapy (CSRT) and one of two postradiotherapy chemotherapies. METHODS Four hundred twenty-one patients between 3 years and 21 years of age with nondisseminated medulloblastoma (MB) were(More)
OBJECT In this study, the authors estimate the prevalence of injuries to the soft tissue of the neck, cervical vertebrae, and cervical spinal cord among victims of abusive head trauma to better understand these injuries and their relationship to other pathophysiological findings commonly found in children with fatal abusive head trauma. METHODS The(More)
BACKGROUND Because few large studies of pediatric ependymoma treatment are available, the authors believed that a retrospective review of treatment outcomes from a single institution would yield potentially valuable information regarding potential prognostic factors. In this article, they report their 20-year institutional experience with this disease. (More)
BACKGROUND Gliomatosis cerebri (GC) is a rare and typically fatal glial neoplasm of the central nervous system. In this report, the authors describe the largest cohort of children to date with GC and explore relations between potential prognostic factors, treatment, and survival. METHODS Imaging, pathologic, and outcome data were reviewed from 13 patients(More)
Central nervous system (CNS) atypical teratoid/rhabdoid tumours (AT/RT) are among the paediatric malignant tumours with the worst prognosis and fatal outcome. Insulin-like growth factor I receptor (IGF-IR) protects cancer cells from apoptosis induced by a variety of anticancer drugs and radiation. In the present study, IGF-IR was expressed in 8/8 primary(More)
Deregulated developmental processes in the cerebellum cause medulloblastoma, the most common pediatric brain malignancy. About 25 to 30% of cases are caused by mutations increasing the activity of the Sonic hedgehog (Shh) pathway, a critical mitogen in cerebellar development. The proto-oncogene Smoothened (Smo) is a key transducer of the Shh pathway.(More)
A comprehensive case–control study was conducted to evaluate parental risk factors for medulloblastoma (MB) and primitive neuroectodermal tumor (PNET). This analysis was conducted to evaluate associations between fathers’ hobbies and risk of their children developing MB/PNET. The hobbies chosen for study were those with similar exposures as occupations(More)
