Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
To assess the efficacy, as measured by progression-free survival at six months (PFS-6), of treating patients with recurrent glioblastoma using GKS to target a tumor volume defined by a combination of gadolinium enhancement and MRS.
6 months
Secondary Outcomes (3)
To describe PFS and OS in pts with recurrent GBM following GKS targeting a tumor volume defined by a combination of gad enhancement and MRS
1 year
To further assess the safety of GKS in patients with recurrent glioblastoma
1 year
To gather initial data regarding the safety and efficacy of treatment of patients with recurrent low-grade or anaplastic glioma with GKS targeting a tumor volume as defined by a combination of gadolinium enhancement and MRS.
1 year
Interventions
Patient treatments will be planned with the Gamma Plan software. The dose will be prescribed to the isodose surface which encompasses the target volume within a range of 50-60% based on a local maximum of 100%. Radiosurgery dose will be prescribed based on volume within the prescribed isodose surface (not to exceed 18 cc)
Eligibility Criteria
You may qualify if:
- Histologically confirmed glioblastoma, gliosarcoma, anaplastic astrocytoma, anaplastic oligodendroglioma, anaplastic oligoastrocytoma, malignant glioma not otherwise specified, low-grade astrocytoma, low-grade oligodendroglioma, low-grade oligoastrocytoma, or low-grade glioma not otherwise specified.
- Prior first-line treatment with surgery or biopsy followed by fractionated radiotherapy with concurrent temozolomide-containing chemotherapy is required for malignant (grade III or IV) glioma patients. Additional prior chemotherapy is allowed, without limitation on number of recurrences. In patients with low-grade tumors, neither prior radiotherapy nor prior chemotherapy is required.
- An interval of \> 2 months since completion of fractionated radiotherapy.
- Age \> 18 years
- Life expectancy of at least 8 weeks.
- Karnofsky Performance Status score (KPS) of ≥ 60
- Documented recurrent disease: Recurrent disease is defined either as histological confirmation of tumor, as an increase in tumor size of at least 25% based upon serial MR images, or as development of a new site of disease.
- Tumor size will be calculated using the sum of the largest cross-sectional perpendicular diameters of contrast-enhancing tumor for high-grade tumors, the sum of the largest cross-sectional perpendicular diameters of FLAIR abnormality for low-grade tumors, or as worsened spectroscopic characteristics for any tumor type (development of ≥ 2 new voxels with CNI ≥ 3, or ≥ 25% increase in the sum of the CNI ratios within a group of previously abnormal voxels \[where abnormal is defined as CNI ≥ 3\]).
- Disease must be evaluable, but does not need to be measurable.
- The target site for GKS does not need to be located in a previously-irradiated area.
- Eligibility for gamma-knife radiosurgery: The decision to treat with gamma-knife radiosurgery will be made by a consensus of the radiation oncology, neurosurgery and neuro-oncology co-chairs or their alternates at the weekly Brain Tumor or Gamma-Knife Tumor Conferences. The MRS defined target volume must be ≤ 15 cc. and not involving eloquent brain (speech/language cortex, motor/sensory cortex, basal ganglia, brainstem, or corpus callosum 2) on an MRI done within 14 days of the planned GKS procedure.
- BUN \< 25 and Cr \< 1.7
- Negative pregnancy test at the time of GKS in any patient who could be pregnant.
- Willingness to forego additional therapy until evidence of disease progression.
- Signed and witnessed informed consent and signed authorization for the release of their protected health information.
You may not qualify if:
- MRS defined tumor volume greater than 15 cc.
- MRS defined tumor volume involving eloquent brain (speech/language cortex, motor/sensory cortex, basal ganglia, brainstem, or corpus callosum).
- Concurrent treatment with chemotherapy.
- Active infectious process requiring IV antibiotics.
- History of any other cancer (except non-melanoma skin cancer or carcinoma in-situ of the cervix), unless in complete remission and off of all therapy for that disease for a minimum of three years.
- Other major medical illness judged by the investigator to preclude prolonged follow-up.
- Any condition that compromises compliance with the objectives and procedures of this protocol, as judged by the principal investigator.
