Abstract
Maximal surgical debulking and radiotherapy have been the cornerstone of therapy for high-grade gliomas. The impact of chemotherapy on outcome has been marginal and, until recently, its usage has been debatable. The development of new drugs and an improved understanding of chemoresistance have reinvigorated interest in this treatment modality. Furthermore, increasing knowledge of gliomagenesis has also led to novel non-cytotoxic approaches to targeting the molecular machinery that is responsible for tumour development and progression. These new strategies, which are currently being evaluated in clinical trials, provide new hope for the future.
