RATIONALE: Drugs used in chemotherapy such as talampanel use different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: This phase II trial is studying how well talampanel works in treating patients with recurrent, progressive high-grade glioma.
- Determine the efficacy of talampanel, in terms of 6-month progression-free survival, in patients with recurrent high-grade gliomas.
- Determine, preliminarily, the toxic effects of this drug in these patients.
- Determine, preliminarily, the quality of life of patients treated with this drug.
- Determine the pharmacokinetics of this drug in patients who are and who are not receiving enzyme-inducing antiepileptic drugs.
OUTLINE: Patients are stratified according to type of glioma (anaplastic astrocytoma vs glioblastoma multiforme). Patients in each stratum are assigned to 1 of 3 treatment groups according to concurrent enzyme-inducing antiepileptic drug use (yes, no, or valproic acid).
Patients in each group receive different doses of oral talampanel 3 times daily on days 1-42. Courses repeat every 42 days in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed at baseline, every 3 weeks during the first course, every 6 weeks before all subsequent courses, and then within 2 weeks of study completion.
Patients are followed within 2 weeks.
PROJECTED ACCRUAL: A total of 91 patients (50 with anaplastic astrocytoma and 41 with glioblastoma multiforme) will be accrued for this study within 1 year.

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.
Angiogenesis plays an essential role in tumors development. In case of central nervous system tumors, the most important role in this process plays VEGF-A. The purpose of this study was to determine t...
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...
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.

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.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
