EpiBrainRad: an epidemiologic study of the neurotoxicity induced by radiotherapy in high grade glioma patients.

Background: Radiotherapy is one of the most important treatments of primary and metastatic brain tumors. Unfortunately, it can involve moderate to severe complications among which leukoencephalopathy is very frequent and implies cognitive deficits such as memory, attention and executive dysfunctions. However, the incidence of this complication is not well established and the risk factors and process are poorly understood.
