Outcomes of Infants and Young Children With Relapsed Medulloblastoma After Initial Craniospinal Irradiation-Sparing Approaches: An International Cohort Study.

Purpose: Infant and young childhood medulloblastoma (iMB) is usually treated without craniospinal irradiation (CSI) to avoid neurocognitive late effects. Unfortunately, many children relapse. The purpose of this study was to assess salvage strategies and prognostic features of patients with iMB who relapse after CSI-sparing therapy.

Features Associated With Weight Loss and Growth Stunting for Young Children During Cancer Therapy.

Features associated with malnutrition are poorly elucidated in pediatric cancer care. We aimed to better understand characteristics associated with weight-for-height (WHZ) and height-for-age (HAZ) changes for infants and young children during cancer treatment. This retrospective study included 434 patients diagnosed <3 years old from 2007 to 2015 at a large pediatric cancer center.

Normalized measures and patient characteristics to identify undernutrition in infants and young children treated for cancer.

Background: Various measures and definitions for undernutrition are used in pediatrics. Younger children treated for cancer are at high risk, but lack well-defined risk-based screening and intervention.

Methods: A retrospective study collected weight longitudinally for patients less than three years-old over two years after initiating cancer treatment.

Efficacy of High-Dose Chemotherapy and Three-Dimensional Conformal Radiation for Atypical Teratoid/Rhabdoid Tumor: A Report From the Children's Oncology Group Trial ACNS0333.

Purpose: Atypical teratoid/rhabdoid tumor (AT/RT) is an aggressive, early-childhood brain tumor without standard effective treatment. To our knowledge, we conducted the first AT/RT-specific cooperative group trial, ACNS0333, to examine the efficacy and safety of intensive postoperative chemotherapy and focal radiation to treat AT/RT.

Patients And Methods: Patients from birth to 22 years of age with AT/RT were eligible.

Morbidity and Mortality Associated With Meningioma After Cranial Radiotherapy: A Report From the Childhood Cancer Survivor Study.

Purpose Little is known about neurologic morbidity attributable to cranial radiotherapy (CRT) -associated meningiomas. Materials and Methods From 4,221 survivors exposed to CRT in the Childhood Cancer Survivor Study, a diagnosis of meningioma and onset of neurologic sequelae were ascertained. Cox proportional hazards regression was used to estimate hazard ratios (HR) and 95% CIs to evaluate the factors associated with neurologic sequelae after subsequent meningioma.

Nonrandomized comparison of neurofibromatosis type 1 and non-neurofibromatosis type 1 children who received carboplatin and vincristine for progressive low-grade glioma: A report from the Children's Oncology Group.

Background: To evaluate tumor responses, event-free survival (EFS), overall survival (OS), and toxicity of chemotherapy, children with neurofibromatosis type 1 (NF1) and progressive low-grade glioma were enrolled into the Children's Oncology Group (COG) A9952 protocol and treated with carboplatin and vincristine (CV).

Methods: Non-NF1 patients were randomized to CV or thioguanine, procarbazine, 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea, and vincristine in COG A9952. NF1 patients were assigned to CV only.

Transient enlargement of craniopharyngioma after radiation therapy: pattern of magnetic resonance imaging response following radiation.

Clinical experience suggests that craniopharyngiomas may temporarily increase in size after radiation therapy (RT). The study goal is to determine the incidence and natural history of this response in a cohort of patients managed at Children's Healthcare of Atlanta (CHOA) or Emory Healthcare (EHC). Between 08/1998 and 06/2009, 41 children and young adults were diagnosed with craniopharyngioma at CHOA and/or EHC.

Randomized study of two chemotherapy regimens for treatment of low-grade glioma in young children: a report from the Children's Oncology Group.

PURPOSE Surgery is curative therapy for pediatric low-grade gliomas (LGGs) in areas of the brain amenable to complete resection. However, LGGs located in areas where complete resection is not possible can threaten both function and life. The purpose of this study was to compare two chemotherapy regimens for LGGs in children younger than age 10 years for whom radiotherapy was felt by the practitioner to pose a high risk of neurodevelopmental injury.

Incidence, risks, and sequelae of posterior fossa syndrome in pediatric medulloblastoma.

Purpose: To investigate the incidence, risks, severity, and sequelae of posterior fossa syndrome (PFS) in children with medulloblastoma.

Methods And Materials: Between 1990 and 2007, 63 children with medulloblastoma at Emory University and Children's Healthcare of Atlanta were treated with craniectomy followed by radiation. Fifty-one patients were assigned to a standard-risk group, and 12 patients were assigned to a high-risk group.

Off-therapy headaches in pediatric brain tumor patients: a retrospective review.

To determine the incidence, timing, and characteristics of headaches in a population of off-therapy pediatric brain tumor patients, a retrospective chart review was conducted on 3 subpopulations of children followed in a multidisciplinary neuro-oncology clinic in the Southeastern United States. Data collected included tumor type and location, treatment, associated symptoms, and description and timing of headaches. In all, 81 charts were reviewed from which headaches in 3 subtypes of tumors were identified (29 medulloblastomas, 36 cerebellar juvenile pilocytic astrocytomas [JPAs], and 16 craniopharyngiomas).

The use of high-dose daily cabergoline in an adolescent patient with macroprolactinoma.

Prolactinomas are rare in children and adolescents but well studied in adults. Dopamine agonists are the treatment of choice for all ages. Bromocriptine is the only agonist approved for use in pediatric patients by the FDA.
