Early necrosis following concurrent Temodar and radiotherapy in patients with glioblastoma.

Concurrent temozolomide (TMZ) and radiotherapy is the new standard of care for patients with newly diagnosed glioblastoma. In 51 consecutive patients treated according to this regimen, 7 patients (14%) manifested surgically confirmed early necrosis without evidence of recurrent tumor. This observation suggests that daily TMZ may represent a potent radiosensitizing regimen.
