Brief summary
RATIONALE: Erlotinib may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth. PURPOSE: Phase II trial to study the effectiveness of erlotinib in treating patients who have recurrent or progressive glioblastoma multiforme.
Detailed description
OBJECTIVES: * Determine the response rate of patients with recurrent or progressive glioblastoma multiforme treated with erlotinib. * Determine the progression-free and overall survival of patients treated with this drug. OUTLINE: Patients receive oral erlotinib daily. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients are followed for survival. PROJECTED ACCRUAL: A total of 73 patients will be accrued for this study.
