ABSTRACT

In this chapter, we briey review the epidemiology of brain metastases to de‚ne the scope of the problem for which HSRT is well suited. Subsequently, we present the data and rationale for the use of SRS in this setting, followed by a discussion of the rationale for HSRT. Next, we present our institutional techniques for HSRT with a focus on clinical scenarios where HSRT may be bene‚cial. Finally, we will review the available data supporting the use of HSRT with a focus on treated metastasis control and normal tissue toxicity. e chapter closes with a brief discussion of controversies and future directions.
