RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of radiation therapy followed by carmustine in treating patients who have supratentorial glioblastoma multiforme.

Condition Intervention Phase
Brain and Central Nervous System Tumors Drug: carmustine Radiation: radiation therapy Radiation: stereotactic radiosurgery Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Trial of Accelerated Radiotherapy Using Weekly Stereotactic Conformal Boosts For Supratentorial Glioblastoma Multiforme

Primary Outcome Measures:
  • Overall Survival [ Time Frame: From registration to date of death or last follow-up. Analysis occurs after all patients have been potentially followed for 18 months. ]

Secondary Outcome Measures:
  • Progression-free Survival [ Time Frame: From registration to date of progression, death or last follow-up. Analysis occurs at the same time as the primary outcome analysis. ]

Enrollment: 80
Study Start Date: March 2001
Study Completion Date: February 2009
Primary Completion Date: November 2004 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: External beam radiotherapy with stereotactic boost
External beam radiotherapy (EBXRT): 50 Gy in 25 daily fractions of 2 Gy. Stereotactic radiotherapy (SRT) boost: 4 treatments of 5 or 7 Gy, once per week during weeks 3-6. Patients will not receive EBXRT on the SRT treatment days.
Drug: carmustine Radiation: radiation therapy Radiation: stereotactic radiosurgery

Detailed Description:


  • Determine the overall and progression-free survival in patients with supratentorial glioblastoma multiforme treated with accelerated radiotherapy and conformal stereotactic radiotherapy boost followed by carmustine.
  • Determine the short and long-term toxicity of this regimen in these patients.
  • Determine the feasibility of this regimen in these patients.

OUTLINE: Patients receive daily accelerated radiotherapy 5 days a week on weeks 1-2. On weeks 3-6, patients receive accelerated radiotherapy 4 days a week (3 days a week on week 6) and conformal stereotactic radiotherapy boost once weekly. Patients then receive carmustine IV over 1-2 hours on days 1-3 every 8 weeks for 6 courses beginning within 1 month after the completion of radiotherapy.

Patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 76 patients will be accrued for this study within 15 months.
