Glioblastoma Multiforme and the Epidermal Growth Factor Receptor

Abstract
Glioblastoma multiforme is one of the most aggressive and recalcitrant cancers. A tumor that can be identified radiographically can sometimes be resected, yielding a putatively clean magnetic resonance image postoperatively, but tumor cells are invariably present in areas of the brain that are at a considerable distance from the site of initial diagnosis. The delivery of radiotherapy to a field encompassing the tumor and a margin of 2 to 3 cm increases survival, but not substantially.
