Gliomas are the most common primary malignant neoplasm of the central nervous system in adults. Despite tangible progress, results remain disappointing, and median survival is 1012 months (1). Several new drugs have been developed that interfere with specific cellular targets in cancer cells. Among them, small-molecule inhibitors of the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) were shown to be effective in the treatment of solid malignancies. Gefitinib (Iressa; AstraZeneca, Wilmington, DE) and erlotinib (Tarceva; Genentech, South San Francisco, CA) are both orally active, selective EGFR tyrosine kinase inhibitors (EGFR-TKIs) that have produced impressive responses in a
