Hypofractionated Stereotactic Radiosurgery in Treating Patients With Large Brain Metastasis
Metastatic Malignant Neoplasm to Brain, Unspecified Adult Solid Tumor, Protocol Specific
About this trial
This is an interventional treatment trial for Metastatic Malignant Neoplasm to Brain focused on measuring Brain metastasis
Eligibility Criteria
Inclusion Criteria:
- Pathologic proven diagnosis of solid tumor malignancy
- One brain metastasis or brain metastasis resection cavity with maximal diameter ≥ 3 cm (or ≥ 14 cc.) and ≤ 6 cm (or ≤ 113 cc.)
- Recursive partitioning analysis (RPA) class I-II/ Karnofsky Performance status (KPS) ≥ 70%
Exclusion Criteria:
- Prior stereotactic radiosurgery (SRS) to adjacent lesion such that planning target volume would have received more than 12 Gy
- RPA class III (KPS < 70%)
- Brain metastasis or resection cavity volume < 3 cm or > 6 cm
- Radiosensitive or non-solid (eg. small cell lung carcinomas, germ cell tumors, leukemias, or lymphomas) or unknown tumor histologies
- Concurrent chemotherapy (no chemotherapy starting 14 days before start of radiation)
- Evidence of leptomeningeal disease by magnetic resonance imaging (MRI) and/or cerebrospinal fluid (CSF) cytology
- Current pregnancy
- More than 8 weeks between resection and radiosurgical procedure
- Metastases to brain stem, midbrain, pons, or medulla or within 5 mm of the optic apparatus (optic nerves and chiasm)
- Inability to undergo MRI evaluation for treatment planning and follow-up
Sites / Locations
- Emory University Hospital/Winship Cancer Institute
- Emory Saint Joseph's Hospital
Arms of the Study
Arm 1
Experimental
Hypofractionated Radiosurgery
HR (Hypofractionated Radiosurgery) delivered in 5 fractions, with a minimum of 2 and a maximum of 3 fractions being delivered per week, to patients with brain metastases or resection cavity greater than 3 cm and less than 6 cm. Dose escalation will proceed according to the Escalation with Overdose Control (EWOC) method with a planned total enrollment of 24 patients, in 8 patient cohorts with 3 patients per cohort. A 4 month observation period will occur for each completed cohort prior to dose escalation, with a goal timeline for trial completion of 4 years from first patient enrollment.
