Management of Specific Tumor Types and Locations
Brain Stem GliomasStandard treatment options:Radiation therapy.Brain stem gliomas have relatively poor prognoses that correlate with histology (when biopsies are performed), location, and extent of tumor. The overall median survival time of patients in studies has been 44 to 74 weeks.Current Clinical TrialsCheck for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with adult brain stem glioma. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.General information about clinical trials is also available from the NCI Web site.Pineal Astrocytic TumorsStandard treatment options:Surgery plus radiation therapy for patients with pilocytic or diffuse astrocytoma.Surgery plus radiation therapy and chemotherapy for patients with higher grade tumors.Depending on the degree of anaplasia, pineal astrocytomas vary in prognoses. Higher grades have worse prognoses. Pilocytic

General Information About Childhood Brain Stem Glioma
Childhood brain stem glioma is a disease in which benign (noncancer) or malignant (cancer) cells form in the tissues of the brain stem. The brain stem is the part of the brain connected to the spinal cord. It is located in the lowest part of the brain,just above the back of the neck. The brain stem is the part of the brain that controls breathing,heart rate,and nerves and muscles used in ...
There is no generally applied staging system for childhood brain stem gliomas. It is uncommon for these tumors to have spread outside the brain stem itself at the time of initial diagnosis. Spread of malignant brain stem tumors is usually contiguous; metastasis via the subarachnoid space has been reported in up to 30% of cases diagnosed antemortem. Such dissemination may occur prior to local relapse but usually occurs simultaneously with or after local disease relapse.The less common tumors of the midbrain, especially in the tectal plate region, have been viewed separately from those of the brain stem because they are more likely to be low grade and have a greater likelihood of long-term survival (approximately 80% 5-year progression-free survival vs. <10% for tumors of the pons).[1,4,5,6,7,8] Similarly, dorsally exophytic and cervicomedullary tumors are generally low grade and have a relatively favorable prognosis. Children younger than 3 years may have a more favorable

Classification of Central Nervous System Tumors
The classification of childhood central nervous system (CNS) tumors is based on histology and location. Tumors are classically categorized as infratentorial, supratentorial, parasellar, or spinal. Immunohistochemical analysis, cytogenetic and molecular genetic findings, and measures of mitotic activity are increasingly used in tumor diagnosis and classification, and will likely alter classification and nomenclature in the future.Primary CNS spinal cord tumors comprise approximately 1% to 2% of all childhood CNS tumors. The classification of spinal cord tumors is based on histopathologic characteristics of the tumor and does not differ from that of primary brain tumors.[2,3,4]Infratentorial (posterior fossa) tumors include the following:Cerebellar astrocytomas (most commonly pilocytic, but also fibrillary and less frequently, high-grade).Medulloblastomas (classic, desmoplastic/nodular, extensive nodularity, anaplastic, or large cell) and variants.Ependymomas (cellular, papillary,
Treatment Option Overview
Many of the improvements in survival in childhood cancer have been made as a result of clinical trials that have attempted to improve on the best available, accepted therapy. Clinical trials in pediatrics are designed to compare new therapy with therapy that is currently accepted as standard. This comparison may be done in a randomized study of two treatment arms or by evaluating a single new treatment and comparing the results with those previously obtained with existing therapy. Because of the relative rarity of cancer in children, all patients with aggressive brain tumors should be considered for entry into a clinical trial. To determine and implement optimum treatment, treatment planning by a multidisciplinary team of cancer specialists who have experience treating childhood brain tumors is required. Radiation therapy of pediatric brain tumors is technically very demanding and should be carried out in centers that have experience in that area in order to ensure optimal results.

Recurrent Childhood Ependymoma
Recurrent childhood ependymoma is a tumor that has recurred (come back) after it has been treated. Childhood ependymoma commonly recurs, usually at the original cancer site. The tumor may come back as long as 15 years or more after initial treatment.
