Whole Brain Radiotherapy + Stereotactic Radiosurgery for Brain Metastasis
Trial Summary
What is the purpose of this trial?
This phase III trial compares the effect of adding whole brain radiotherapy with hippocampal avoidance and memantine to stereotactic radiosurgery versus stereotactic radiosurgery alone in treating patients with cancer that has spread to the brain and come back in other areas of the brain after earlier stereotactic radiosurgery. Hippocampus avoidance during whole-brain radiation therapy decreases the amount of radiation that is delivered to the hippocampus, which is a brain structure that is important for memory. The medicine memantine is also often given with whole brain radiation therapy because it may decrease the risk of side effects of radiation on thinking and memory. Stereotactic radiosurgery delivers a high dose of radiation only to the small areas of cancer in the brain and avoids the surrounding normal brain tissue. Adding whole brain radiotherapy with hippocampal avoidance and memantine to stereotactic radiosurgery may be effective in shrinking or stabilizing cancer that has spread to the brain and returned in other areas of the brain after receiving stereotactic radiosurgery.
Eligibility Criteria
This trial is for patients with certain cancers (like lung, breast, kidney cancer) that have spread to the brain and returned after initial treatment. Participants must have had their first or second relapse at least 8 weeks post-initial radiosurgery and within 21 days before joining the study. They should be able to undergo MRI scans, swallow pills, and not have severe co-morbidities or a history of specific conditions like multiple sclerosis.Inclusion Criteria
