Use of Pulsed Low-dose Rate Re-irradiation for Recurrent Glioma (PULSAR)

Radiation treatment will be carried out with high-energy photons (6MV) using intensity modulated radiation therapy (IMRT) or volumetric arc radiation therapy (VMAT). The daily dose is 2 Gy, divided into 10 subfractions of 0.2 Gy spaced by 3 minutes. The cumulative dose will be individualized for each patient and can range from a minimum of 40 Gy to a maximum of 60 Gy.
