GliaSite Radiation Therapy System

Researchers at the Johns Hopkins Comprehensive Brain Tumor Center discovered and developed the GliaSite Radiation Therapy System (RTS), which delivers radiation from within the hole created by the surgical removal of a malignant brain tumor.

GliaSite RTS is used for newly diagnosed, metastatic and recurrent brain tumors.

A few days after surgical removal of the tumor, liquid radiation is delivered to the edges of the tumor hole through a catheter (a thin, hollow tube). The liquid radiation targets places in and around the tumor site where cancer cells may remain. It delivers a precise amount of radiation for a few days. Then the catheter is removed.
