RATIONALE: Gathering information about patients with central nervous system tumors over time may help doctors learn more about the disease and find better methods of treatment and on-going care.
PURPOSE: This natural history study is collecting disease-related health information over time from patients with central nervous system tumors being evaluated at the National Institutes of Health.
- Follow patients with CNS tumors that are representative of important scientific and/or clinical principles.
- Attain a steady flow of patients with CNS tumors at the NIH, which will help to educate nurses, medical residents, clinical fellows, and others in management and care of this subgroup of cancer patients.
OUTLINE: Patients receive an initial evaluation by the NCI Neuro-Oncology Branch at the NIH Clinical Center. Patients may choose to end their participation on the study after the initial evaluation or may continue being evaluated at NIH. Generally, patients living in close proximity to the NIH are followed at NIH every 3-6 months. Patients living at a distance from NIH resume standard care with their local physician, but either they are followed periodically at NIH (e.g., if disease progression occurs) or they (and/or their physician) are contacted by the Neuro-Oncology Branch at least every 6 months to generally follow the natural history of the disease and patient outcome.
Patients may undergo any or all of the following procedures at initial or follow-up evaluations: MRI or CT scan, PET scan, blood tests, neurologic exam, and physical exam and history.
PROJECTED ACCRUAL: A total of 3,000 patients will be accrued for this study.

RATIONALE: Screening tests may help doctors determine which patients are eligible for treatment on clinical trials. PURPOSE: This clinical trial is screening patients with central nervous...
RATIONALE: Radiation therapy directed at the central nervous system may change the way blood vessels form in young patients. It may also change brain function, the ability to see and hear,...
RATIONALE: Genetic studies may help in understanding the genetic processes involved in the development of some types of cancer. PURPOSE: Genetic study to learn more about genes involved i...
Background: The number of people who get tumors of the brain or central nervous system (CNS) is lower than other cancers. But these tumors cause a higher rate of serious effects and even ...
RATIONALE: PTC299 may stop the growth of tumor cells by blocking blood flow to the tumor. PURPOSE: This phase I trial is studying the side effects and the best dose of PTC299 in treating ...
Hemangioblastomas (HBs) are benign vascular tumors of the central nervous system and histologically contain abundant microvessels. Therefore, they clinically exhibit vascular malformation-like charact...
Central nervous system (CNS) tumors are a group of neoplasms that originate from various cells in the CNS. The increasing incidence and prevalence of this type of tumor in developing countries are str...
The purpose of this study was to examine the prevalence and predictors of social difficulties in adolescent survivors of central nervous system (CNS) tumors.
Primary central nervous system lymphoma (PCNSL) is a rare disease. Studies of PCNSL in patients with rheumatic diseases are lacking. Neither clinical symptoms nor radiographic manifestation is specifi...
This article details the epidemiology and clinical manifestations of central nervous system (CNS) tuberculosis (TB), provides guidance for diagnostic imaging and CSF testing, and recommends treatment ...
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2059)
Diseases of the parasympathetic or sympathetic divisions of the AUTONOMIC NERVOUS SYSTEM; which has components located in the CENTRAL NERVOUS SYSTEM and PERIPHERAL NERVOUS SYSTEM. Autonomic dysfunction may be associated with HYPOTHALAMIC DISEASES; BRAIN STEM disorders; SPINAL CORD DISEASES; and PERIPHERAL NERVOUS SYSTEM DISEASES. Manifestations include impairments of vegetative functions including the maintenance of BLOOD PRESSURE; HEART RATE; pupil function; SWEATING; REPRODUCTIVE AND URINARY PHYSIOLOGY; and DIGESTION.
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
