Study Overview
Brief Summary
RATIONALE: Brachytherapy uses radioactive material to kill cancer cells remaining after surgery.
PURPOSE: Phase I trial to study the effectiveness of brachytherapy in treating patients who have recurrent malignant glioma.
Detailed Description
OBJECTIVES:
- Determine the maximum tolerated dose of brachytherapy using an intracavitary applicator and liquid iodine I 125 in patients with recurrent malignant glioma.
- Determine the acute and chronic toxicity of this therapy in these patients.
OUTLINE: This is a dose-escalation, multicenter study.
Within 3-21 days after surgical resection, patients receive brachytherapy using an intracavity balloon application (GliaSite) with iodine I 125 solution for a total of 5-7 days.
Cohorts of 5-10 patients receive escalating doses of brachytherapy until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which at least 2 of 10 patients experience dose-limiting toxicity.
