Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase II trial studies the safety and efficacy of frameless fractionated stereotactic radiation therapy for brain metastases. Frameless fractionated stereotactic radiosurgery is a specialized radiation therapy that delivers 3 to 5, high dose fractions of radiation directly to the brain lesions while sparing normal tissues.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVES:

I. To assess the efficacy and safety of frameless fractionated stereotactic radiation therapy (FFSRT) on the treatment of solitary and oligometastatic brain metastases in the MD Anderson Houston Area Locations, MD Anderson Radiation Treatment Centers in New Mexico, MD Anderson affiliates and the main campus of MD Anderson, for patients unable or unwilling to undergo frame-based stereotactic radiosurgery (SRS).

SECONDARY OBJECTIVES:

I. To assess 6-month local control, intracranial progression-free survival and overall survival.

II. To collect data on charges and reimbursements of patients treated with FFSRT to compare those charges and reimbursements if the same patients had been treated with single-fraction, frame-based gamma knife SRS.

OUTLINE:

Patients undergo FFSRT daily over 30 minutes for 3-5 days.

After completion of study treatment, patients are followed up every 3 months for up to 1 year.

* Each brain lesion must be less than or equal to 5 cm in diameter and not an optimal surgical candidate
* Patient must be able have a magnetic resonance imaging (MRI) of the brain for treatment planning
* Histologic confirmation of malignancy
* For patients of childbearing potential, non-pregnant state, confirmed by negative serum or urine beta-human chorionic gonadotropin (HCG) within (7) days of planned radiation treatment
* Glomerular filtration rate (GFR) adequate for intravenous (IV) contrast delivery for imaging
* No concurrent chemotherapy
* Patient may have had prior therapy for brain metastasis, including radiosurgery and surgical resection at the discretion of the treating physician however only new untreated lesions will be followed on protocol.

Exclusion Criteria
