Phase III Trial of Post-Surgical Single Fraction Stereotactic Radiosurgery (Srs) Compared with Fractionated Srs (Fsrs) For Resected Metastatic Brain Disease (A071801)

Background Information

This study is being done to answer the following question: does fractionated (multiple treatment sessions) radiosurgery delivered to the surgical cavity in the brain (the part of the brain where the brain metastasis was resected) decrease the risk of tumor recurring in the surgical cavity compared to single fraction (single treatment session) radiosurgery?

The usual approach for patients who are not in a study is treatment with single fraction radiosurgery. These treatments can reduce symptoms and may stop the tumor from growing for a few months or longer.

Radiosurgery, despite its name, is a non-surgical procedure that delivers precisely-targeted radiation at much higher doses, in only a single (or few treatments) as compared to traditional radiation therapy. Radiosurgery utilizes immobilization (a head frame or a soft plastic mask that forms to the shape of your face that helps hold the head in place during treatment) during the procedure to allow very precise targeting of tumors. Radiosurgery is typically done as an outpatient procedure. For most patients, the actual time on the radiosurgery treatment machine is in the range of 20 to 90 minutes.

This study has public funding from the National Cancer Institute (NCI), part of the National Institutes of Health (NIH) in the United States Department of Health and Human Services.
