Procarbazine and Isotretinoin in Treating Patients With Recurrent Primary Malignant Gliomas

2014-08-27 03:58:39 | BioPortfolio

Summary

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known whether giving procarbazine alone or with isotretinoin is more effective for recurrent primary malignant glioma.

PURPOSE: Randomized phase III trial to compare the effectiveness of procarbazine alone or with isotretinoin in treating patients with recurrent primary malignant gliomas.

Description

OBJECTIVES: I. Determine whether the combination of isotretinoin and procarbazine can improve time to progression and survival compared to procarbazine alone in patients with recurrent malignant gliomas. II. Document the toxicity of these two regimens in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to receive procarbazine alone or in combination with isotretinoin. Arm I: Patients receive oral procarbazine once daily on days 1-14 every 28 days. Oral isotretinoin is administered every 12 hours on days 15-28 every 28 days. Patient receive 6 courses of combined therapy, then continue with oral isotretinoin alone on days 15-28 of each 28 day course, until disease progression or unacceptable toxicity. Arm II: Patients receive procarbazine by mouth once daily on days 1-14 followed by 2 weeks of rest. Patients receive a total of 6 courses of treatment in the absence of disease progression and unacceptable toxicity. Patients are followed until death.

PROJECTED ACCRUAL: This study will accrue a total of 194 patients (97 per treatment group).

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.
