Updated on 22 March 2022


This is a research trial that seeks to break up the total radiation dose into multiple smaller radiation treatments, termed fractionated stereotactic radiosurgery (FSRS) which may make the treatment feasible. Fractionated sterotatcic radiation, the risks of FSRS, and possible costs will be described later in this document. This clinical trial is for people who have had no prior whole brain radiation.
