Radiation Therapy or Temozolomide in Treating Patients With Gliomas

2014-08-27 03:50:21 | BioPortfolio

Summary

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether radiation therapy is more effective than temozolomide in treating gliomas.

PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared to temozolomide in treating patients with gliomas.

Description

OBJECTIVES:

Primary

- Compare the progression-free survival of patients with low-grade gliomas treated with radiotherapy vs temozolomide.

Secondary

- Compare the overall survival of patients treated with these regimens.

- Determine whether the incidence of late toxicity can be decreased in patients who are randomized to receive temozolomide.

- Compare the toxic effects of these regimens in these patients.

- Compare the quality of life of patients treated with these regimens.

OUTLINE: This is a randomized, controlled, multicenter study. Patients are stratified according to participating center, chromosome 1p status (deleted vs normal vs undeterminable), contrast enhancement on MRI (yes vs no), age (< 40 years vs ≥ 40 years), and WHO performance status (0 or 1 vs 2). Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients undergo radiotherapy once daily, 5 days a week, for a total of 28 fractions (i.e., 5½ weeks).

- Arm II: Patients receive oral temozolomide once daily on days 1-21. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Quality of life is assessed at baseline and then every 3 months until disease progression.

After completion of study treatment, patients are followed every 6 months for survival.

PROJECTED ACCRUAL: A minimum of 699 patients (a total of 466 randomized [233 per treatment arm]) will be accrued for this study within 5 years.

Medical and Biotech [MESH] Definitions

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.
