Neuroblastoma Screening (PDQ®): Screening - Patient Information [NCI] - Stages of Adult Brain Tumors
There is no standard staging system for adult brain and spinal cord tumors.The extent or spread of cancer is usually described as stages. There is no standard staging system for brain and spinal cord tumors. Brain tumors that begin in the brain may spread to other parts of the brain and spinal cord, but they rarely spread to other parts of the body. Treatment of brain and spinal cord tumors is based the following:The type of cell in which the tumor began.Where the tumor formed in the brain or spinal cord.The amount of cancer left after surgery.The grade of the tumor.Treatment of brain tumors that have spread to the brain from other parts of the body is based on the number of tumors in the brain.Imaging tests may be repeated after surgery to help plan more treatment.Some of the tests and procedures used to diagnose a brain or spinal cord tumor may be repeated after treatment to find out how much tumor is left.
Neuroblastoma Screening (PDQ®): Screening - Patient Information [NCI] - Cellular Classification of Pituitary Tumors
Pituitary adenomas can be classified according to staining affinities of the cell cytoplasm, size, endocrine activity, histologic characteristics, hormone production and contents, ultrastructural features, granularity of the cell cytoplasm, cellular composition, cytogenesis, and growth pattern. Recent classifications, however, omit criteria based on tinctorial stains (i.e., acidophilic, basophilic, and chromophobic) because of the poor correlation between staining affinities of the cell cytoplasm and other pathological features of pituitary tumors, such as the type of hormone produced and cellular derivation.[1,2]A unifying pituitary adenoma classification incorporates the histological, immunocytochemical, and electron microscopic studies of the tumor cells, and stresses the importance of hormone production, cellular composition, and cytogenesis. This classification emphasizes the structure-function relationship and attempts to correlate morphologic features with secretory

Neuroblastoma Screening (PDQ®): Screening - Patient Information [NCI] - General Information About Adult Brain Tumors
An adult brain tumor is a disease in which abnormal cells form in the tissues of the brain. There are many types of brain and spinal cord tumors. The tumors are formed by the abnormal growth of cells and may begin in different parts of the brain or spinal cord. Together,the brain and spinal cord make up the central nervous system (CNS). The tumors may be benign (not cancer) or malignant ...
Neuroblastoma Screening (PDQ®): Screening - Patient Information [NCI] - Cellular Classification of Childhood Brain Stem Glioma
Brain stem gliomas are classified according to their location, radiographic appearance, and histology (when obtained). Brain stem gliomas may occur in the pons, midbrain, tectum, dorsum of the medulla at the cervicomedullary junction, or in multiple regions of the brain stem. The tumor may contiguously involve the cerebellar peduncles, cerebellum, the cervical spinal cord, and/or thalamus. The majority of childhood brain stem gliomas are diffuse, fibrillary astrocytomas that involve the pons (diffuse intrinsic pontine gliomas [DIPG]), often with contiguous involvement of other brain stem sites.[1,2] The prognosis is extremely poor for these tumors. Focal pilocytic astrocytomas have a more favorable prognosis. These most frequently arise in the tectum of the midbrain, focally within the pons, or at the cervicomedullary junction where they are often exophytic, and they have a far better prognosis than diffuse intrinsic tumors.[3,4,5]The genomic characteristics of DIPG appear to
Neuroblastoma Screening (PDQ®): Screening - Patient Information [NCI] - Stage Information and Treatment of Newly Diagnosed and Recurrent Childhood Spinal Cord Tumors
There is no uniformly accepted staging system for childhood primary spinal cord tumors. These tumors are classified and treated based on their location within the spinal cord and histology. Refer to one of the following PDQ summaries for more information on the staging and treatment of newly diagnosed and recurrent childhood spinal cord tumors:Childhood Astrocytomas Treatment.Childhood Central Nervous System Embryonal Tumors Treatment.Childhood Ependymoma Treatment.In general, at the time of recurrence, low-grade spinal cord glial tumors can be treated with re-resection with or without the use of radiation therapy. Recurrent low-grade and high-grade tumors that cannot be re-resected can be treated on protocols designed for histologically similar brain tumors.
Neuroblastoma Screening (PDQ®): Screening - Patient Information [NCI] - General Information About Childhood Brain and Spinal Cord Tumors
Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2002, childhood cancer mortality decreased by more than 50%. Childhood and adolescent cancer survivors require close follow-up because cancer therapy side effects may persist or develop months or years after treatment. Refer to the PDQ summary on Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.Primary brain tumors are a diverse group of diseases that together constitute the most common solid tumor of childhood. Brain tumors are classified according to histology, but tumor location and extent of spread are important factors that affect treatment and prognosis. Immunohistochemical analysis, cytogenetic and molecular genetic findings, and measures of mitotic activity are increasingly used in tumor diagnosis and classification.IncidencePrimary central
Childhood Central Nervous System Atypical Teratoid/Rhabdoid Tumor Treatment (PDQ®): Treatment - Patient Information [NCI] - Treatment Option Overview
There are different types of treatment for patients with central nervous system atypical teratoid/rhabdoid tumor.Different types of treatment are available for patients with central nervous system atypical teratoid/rhabdoid tumor (AT/RT). Treatment for AT/RT is usually within a clinical trial. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer.Clinical trials are taking place in many parts of the country. Information about ongoing clinical trials is available from the NCI Web site. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team.Patients may want to think about taking part in a clinical trial.For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and
