Status: Completed

Conditions: Neoplasm Metastasis

Treatments: Radiation: Novalis Shaped Beam Surgery

Details and patient eligibility

About

This study is to look more closely at the tumor removed during your surgery, and to follow your condition after your treatment.

The purpose of this study is to determine what side effects are common or more rare from this treatment, how well the treatment has worked for you, and to track whether you develop other brain metastases.

Enrollment: 25 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Patients must have a previously histopathologically proven diagnosis of malignancy.
• Patients must be evaluated by Neurosurgery and Radiation Oncology
• Patients must have 1-3 brain metastases seen on MRI or CT imaging. At least one brain metastases must be considered resectable by craniotomy as determined by the treating neurosurgeon. Brain lesion resection must be considered standard of care. A not uncommon situation is for a patient to undergo resection of a solitary metastasis, but prove to have more lesions on subsequent MRIs (perhaps too small to be seen on a pre-operative MRI). These patients will be eligible if the total number of lesions is 1-3.
• All lesions must be treatable by SRS as determined by the treating neurosurgeon and radiation oncologist.
• All lesions must be <4 cm in greatest dimension. For patients with more than 1 brain metastases, only 1 lesion can exceed 3 cm in greatest dimension.
• In patients treated to the post-op surgical cavity, this cavity must be encompassed by a CTV of <5 cm.
• Patients must have a Karnofsky performance status ≥60.
• Extracranial disease must not be considered imminently life threatening (<2 month anticipated survival from extracranial disease).
• Patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines.

Exclusion criteria

• KPS<60
• life expectancy > 2 months
