Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to see if Cs-131 brachytherapy is effective in people with recurrent brain cancer who are scheduled to have brain surgery for removal of their tumor(s). The researchers would like to see whether Cs-131 prevents brain tumors from growing back after surgery.The researchers will compare Cs-131 brachytherapy (which occurs during brain surgery) with the usual approach of brain surgery without brachytherapy. The researchers will compare both the effectiveness and safety of the two approaches.
