Adult Brain Tumors Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Classification of Adult Brain Tumors
This classification is based on the World Health Organization (WHO) classification of central nervous system (CNS) tumors. The WHO approach incorporates and interrelates morphology, cytogenetics, molecular genetics, and immunologic markers in an attempt to construct a cellular classification that is universally applicable and prognostically valid. Earlier attempts to develop a TNM-based classification were dropped: tumor size (T) is less relevant than tumor histology and location, nodal status (N) does not apply because the brain and spinal cord have no lymphatics, and metastatic spread (M) rarely applies because most patients with CNS neoplasms do not live long enough to develop metastatic disease.The WHO grading of CNS tumors establishes a malignancy scale based on histologic features of the tumor. The histologic

Childhood Brain Stem Glioma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Treatment Option Overview for Childhood Brain Stem Glioma
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 that were previously obtained with existing therapy. Because of the relative rarity of cancer in children, all patients with 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 (including 3-dimensional conformal radiation therapy) of pediatric brain tumors is technically very demanding and should be carried out in centers that have

Neuroblastoma Screening (PDQ®): Screening - Patient Information [NCI] - Neuroblastoma Screening
Tests are used to screen for different types of cancer.Some screening tests are used because they have been shown to be helpful both in finding cancers early and in decreasing the chance of dying from these cancers. Other tests are used because they have been shown to find cancer in some people; however, it has not been proven in clinical trials that use of these tests will decrease the risk of dying from cancer.Scientists study screening tests to find those with the fewest risks and most benefits. Cancer screening trials also are meant to show whether early detection (finding cancer before it causes symptoms) decreases a person's chance of dying from the disease. For some types of cancer, the chance of recovery is better if the disease is found and treated at an early stage.Clinical trials that study cancer screening methods are taking place in many parts of the country. Information about ongoing clinical trials is available from the NCI Web site.There is no standard or routine
Childhood Ependymoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Histopathologic Classification of Childhood Ependymal Tumors
In the most recent World Health Organization (WHO) classification of brain tumors, ependymal tumors are classified into four main subtypes:Subependymoma (WHO Grade I).Myxopapillary ependymoma (WHO Grade I).Ependymoma (WHO Grade II). Variants include cellular, papillary, tanycytic, clear cell, and mixed.Anaplastic (also known as malignant) ependymoma (WHO Grade III).The subependymoma is a slow-growing benign neoplasm, typically attached to the ventricle wall, and is composed of glial tumor cell clusters embedded in a fibrillary matrix. The myxopapillary ependymoma arises almost exclusively in the location of the conus medullaris, cauda equina, and filum terminale of the spinal cord, and is characterized histologically by tumor cells arranged in a papillary manner around vascularized myxoid stromal cores.The ependymoma, which is considered a Grade II neoplasm originating from the walls of the ventricles or from the spinal canal, is composed of neoplastic ependymal cells.
Childhood Brain and Spinal Cord Tumors Treatment Overview (PDQ®): Treatment - Patient Information [NCI] - About This PDQ Summary
About PDQPhysician Data Query (PDQ) is the National Cancer Institute's (NCI's) comprehensive cancer information database. The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries come in two versions. The health professional versions have detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions have cancer information that is accurate and up to date and most versions are also available in Spanish.PDQ is a service of the NCI. The NCI is part of the National Institutes of Health (NIH). NIH is the federal government's center of biomedical research. The PDQ summaries are based on an independent review of the medical literature. They are not policy statements of the NCI or the NIH.Purpose of This SummaryThis PDQ cancer information summary has current
