Radiation Therapy With and Without Combination Chemotherapy in Patients With Resected Anaplastic Oligodendroglioma

Brain and Central Nervous System Tumors Clinical Trial

Official title: PHASE III STUDY OF ADJUVANT PROCARBAZINE, CCNU AND VINCRISTINE CHEMOTHERAPY IN PATIENTS WITH HIGHLY ANAPLASTIC OLIGODENDROGLIOMA

Status Completed

Clinical Trial Summary

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells, and may be an effective treatment for anaplastic oligodendroglioma. Combining combination chemotherapy with radiation therapy may kill more tumor cells.

PURPOSE: Randomized phase III trial to compare radiation therapy with and without combination chemotherapy in patients with resected anaplastic oligodendroglioma.

Clinical Trial Description

OBJECTIVES: I. Compare survival and time to first progression in patients with anaplastic oligodendroglioma treated with radiotherapy with or without adjuvant procarbazine, lomustine, and vincristine (PCV) following surgical resection. II. Investigate the effect of PCV on quality of life and neurologic function in these patients. III. Determine the toxicity of PCV in these patients. IV. Correlate chromosomal lesions (1p and/or 19q, 9p, p53 loss and mutation, amplification of chromosome 7, or loss of chromosome 10) with progression-free and overall survival in patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to age, extent of resection, performance status, prior surgery, and participating center. Patients are randomized to one of two treatment arms. Arm I: Within 4-6 weeks after surgery, patients undergo radiotherapy over 7 weeks to the residual tumor volume. Arm II: Patients undergo radiotherapy as in arm I, then begin chemotherapy within 4 weeks after the completion of radiotherapy. Patients receive oral lomustine on day 1, oral procarbazine on days 8-21, and vincristine IV on days 8 and 29. Treatment repeats every 6 weeks in stable and responding patients for a total of 6 courses. Patients with disease recurrence may receive 6 additional courses of chemotherapy as above or another modality at the investigator's discretion. Patients are followed every 3 months for 1 year and then every 6 months for survival.

PROJECTED ACCRUAL: A total of 350 patients will be accrued for this study within 4 years. ;
