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

2014-07-23 21:57:08 | BioPortfolio

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.

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.

Medical and Biotech [MESH] Definitions

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.

Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.

Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.

An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 2.7.7.4.
