Radiation-induced cognitive toxicity: pathophysiology and interventions to reduce toxicity in adults.

abstract：BACKGROUND:Temozolomide (TMZ) resistance in Glioblastoma (GBM) is mediated by the DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT). MGMT promoter methylation (occurs in about 40% patients) is associated with loss of MGMT expression (MGMT-) that compromises DNA repair, leading to a favorable response to ...
