Radiation Therapy With or Without Temozolomide in Treating Patients With Newly Diagnosed Glioblastoma Multiforme
Summary
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if radiation therapy is more effective with or without temozolomide for glioblastoma multiforme.
PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without temozolomide in treating patients who have newly diagnosed glioblastoma multiforme.
Description
OBJECTIVES: I. Compare the efficacy of radiotherapy with or without temozolomide in terms of overall survival in patients with newly diagnosed glioblastoma multiforme. II. Compare the toxicity profiles of these regimens in these patients. III. Compare the progression free survival of these patients treated with these regimens. IV. Compare the quality of life in these patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center, age (under 50 vs 50 and over), WHO/ECOG performance status (0-1 vs 2), and extent of surgical resection (biopsy only vs complete or incomplete resection). Patients are randomized to one of two treatment arms. Arm I: Patients undergo radiotherapy 5 days a week for 6 weeks. Arm II: Patients undergo radiotherapy as in arm I concurrently with oral temozolomide daily for 6 weeks. Patients then receive adjuvant oral temozolomide alone on days 1-5 every 28 days for 6 courses beginning 4 weeks after completion of radiotherapy. Quality of life is assessed prior to the study, at week 4 during radiotherapy, at 4 weeks after completion of radiotherapy, at the end of courses 3 and 6 of adjuvant chemotherapy (arm II), and then every 3 months until disease progression. Patients are followed every 3 months until disease progression or death.
PROJECTED ACCRUAL: A total of 520 patients (260 per treatment arm) will be accrued for this study within 3.5 years.

Medical and Biotech [MESH] Definitions
Brain Neoplasms
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.
Neuroectodermal Tumors, Primitive
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)
Autonomic Nervous System Diseases
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.
Central Nervous System
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
Central Nervous System Venous Angioma
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.
