Official title
Phase II Study of Gamma-Knife Radiosurgery Using Magnetic Resonance Spectroscopy for Target Definition in Patients With Recurrent Glioma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to assess the efficacy, of treating patients with recurrent glioblastoma using Gamma-Knife Radiosurgery (GKS) to target a tumor volume defined by a combination of gadolinium enhancement and magnetic resonance spectroscopy (MRS). This is a single center, Phase II trial. A total of 40 glioblastoma patients will be enrolled into the primary arm of the trial. In addition, a minimum of 10 patients with recurrent anaplastic (grade III) gliomas and a minimum of 10 patients with recurrent low-grade (grade II) gliomas will be enrolled into exploratory arms. The investigators hypothesize that the use of a combination of gadolinium enhancement and elevated Cho:NAA ratio via MRS to determine the treatment target volume for Gamma Knife may be an effective way to treat focally-recurrent glioblastoma.
