Abstract
Radiotherapy is an important component of the treatment for primary and metastatic
brain tumors. Due to the close proximity of critical structures and normal brain parenchyma, Central
Nervous System (CNS) radiotherapy is associated with adverse effects such as neurocognitive
deficits, which must be weighed against the benefit of improved tumor control. Advanced radiotherapy
technology may help to mitigate toxicity risks, although there is a paucity of high-level
evidence to support its use. Recent advances have been made in the treatment for gliomas, meningiomas,
benign tumors, and metastases, although outcomes remain poor for many high grade
tumors. This review highlights recent developments in CNS radiotherapy, discusses common
treatment toxicities, critically reviews advanced radiotherapy technologies, and highlights promising
treatment strategies to improve clinical outcomes in the future.
