简要总结
RATIONALE: Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. External-beam radiation therapy uses high-energy x-rays to kill tumor cells. Combining internal radiation with external-beam radiation therapy may kill any remaining tumor cells following surgery.
PURPOSE: Phase I trial to study the effectiveness of combining internal radiation therapy with external-beam radiation therapy in treating patients who have undergone surgery for glioblastoma multiforme.
详细描述
OBJECTIVES:
- Determine the maximum tolerated dose of brachytherapy administered via GliaSite RTS™ applicator followed by external beam radiotherapy in patients with newly diagnosed glioblastoma multiforme.
- Determine the acute and chronic toxicity of brachytherapy administered via GliaSite RTS™ in these patients.
- Determine the survival rate of patients treated with this regimen.
OUTLINE: This is a multicenter, dose-escalation study of brachytherapy.
Patients undergo craniotomy for histologic confirmation of glioblastoma multiforme, surgical resection, and placement of a GliaSite RTS™ applicator that includes Iotrex™.
Beginning 3-21 days after surgery, patients undergo brachytherapy via the GliaSite RTS™ applicator. Within 30 days of brachytherapy (no more than 60 days after resection) patients undergo external beam radiotherapy 5 days a week for 6 weeks in the absence of disease progression or unacceptable toxicity.
