[Radiation therapy of adult cerebral glioblastoma:]

For the past twenty years, 85 adult patients with cerebral glioblastoma were treated with postoperative radiation therapy (RT). Hypofractionated RT (5 Gy twice a week) was performed in 31 patients. The survival rate of the hypofractionated RT was superior to the conventionally fractionated RT, especially in the patients involved mainly in the frontal lobe. In the hypofractionation group, misonidazole proved of benefit to the survival. In future, hyperfractionation of RT seems reasonable to be explored for improving CNS tolerance.
