Their aggressiveness is partly determined by the histological aspect, the diffuse anaplastic forms being the most malignant. These forms and less aggressive but incompletely operated ones must be irradiated.
Studies to demonstrate the impact of increased radiation doses on tumour control are under way.

Several reasons may militate in its favour when some or all of them are brought together (young age, technical complexity, and need for dose escalation).
Schedule of irradiation
Daily sessions, spread over approximately 6 to 7 weeks.
