High grade gliomas (HGG) have a propensity to recur locally and have poor outcomes. As such, safe and effective treatment is paramount. Target treatment with stereotactic radiation allows safe re-irradiation through minimizing normal brain tissue radiation due to its high precision. In this review, we evaluated the clinical experiences using SRS and FSRT for re-irradiation in HGG. We report the radiobiological advantages and disadvantages of both modalities as well as the safety and efficacy published in current literature.
