Between 1975 and 1989, 108 children with newly diagnosed medulloblastoma/primitive neuroectodermal tumor (MB/PNET) of the posterior fossa were treated at the authors' institution. The patients were managed uniformly, and treatment included aggressive surgical resections, postoperative staging evaluations for extent of disease, and craniospinal radiation(More)
It has previously been reported in a single-institution trial that progression-free survival of children with medulloblastoma treated with radiotherapy and 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU), cisplatin, and vincristine chemotherapy during and after radiotherapy was better than the outcome in children treated with radiotherapy alone. To(More)
Twenty-four children, aged 1.5-20 yr at diagnosis, with noncortical brain tumors, primarily medulloblastoma, have been followed for 3-4 yr for intellectual status. All the children received craniospinal irradiation, and 19 of 24 received chemotherapy as well. For the group as a whole. Full Scale IQ fell from 104 at baseline to 91 at final follow-up.(More)
The feasibility of radical surgery for astrocytomas of the optic chiasm/hypothalamus has been reported by several groups. Such surgery carries significant risks, however, including permanent damage to the pituitary gland, optic apparatus, hypothalamic structures, and carotid arteries. The benefits of radical surgery, both in terms of efficacy and toxicity,(More)
Twenty children with meningiomas (ages 18 months to 17 years) received initial therapy at the Children's Hospital of Philadelphia between January 1975 and June 1991, accounting for 2% of children with primary brain tumors seen during that time interval. All were verified histopathologically, and none had had prior irradiation. Fifteen were male and 5(More)
Cognitive function and school achievement were studied prospectively over 3 to 4 years in 19 children treated for brain tumors with whole-brain radiotherapy; 14 of 19 also received adjuvant chemotherapy. For the group as a whole, mean IQ fell from a baseline of 104 to 92 at follow-up (p < 0.01). Age was inversely correlated with change in IQ over time (r =(More)
Between 1975 and 1989, 45 children with newly diagnosed intracranial ependymomas were treated at the authors' institution. Patients were managed with aggressive surgical resection, followed by postoperative CT or MRI scans to evaluate the extent of resection. Most patients received involved-field radiation therapy, however 10 were treated with craniospinal(More)
Craniospinal radiation therapy (CSRT) combined with chemotherapy results in significant endocrine morbidity. Between 1987 and 1990, a trial using 18 Gy was conducted to treat 10 young children with medulloblastoma. There were 7 survivors. We compared the endocrine outcome in these children (group 18 Gy) to that of a comparable group treated with(More)
An international research consortium has been formed to facilitate evidence-based introduction of MR-guided radiotherapy (MR-linac) and to address how the MR-linac could be used to achieve an optimized radiation treatment approach to improve patients' survival, local, and regional tumor control and quality of life. The present paper describes the(More)
Medulloepithelioma is an uncommon childhood tumor of the central nervous system (CNS) whose histopathological appearance has been confused with medulloblastoma and other childhood primitive neuroectodermal tumors (PNETs), but which has a vastly different clinical course. The authors have reviewed the clinical features and treatment responses of eight(More)
