Trial Summary

What is the purpose of this trial?This phase I/II trial studies the side effects and the best dose of stereotactic radiosurgery and to see how well it works in treating patients with large brain metastases. Radiosurgery can send x-rays directly to the tumor and cause less damage to normal tissue.

Eligibility Criteria

This trial is for patients with large brain metastases from solid tumors, excluding small cell lung cancer, lymphoma, and germ cell cancers. Participants must have lesions 2-4 cm in diameter suitable for stereotactic radiosurgery (SRS), may have had previous SRS or whole brain radiation therapy over 3 months ago, and be able to consent.

Inclusion Criteria

My cancer is not small cell lung cancer, lymphoma, or germ cell.
Patient must be able to provide written informed consent
I am receiving SRS treatment for brain cancer spread.

Exclusion Criteria

My radiation treatment plan doesn't meet specific uniformity criteria.
My cancer is not located in the brainstem.
My cancer is not small cell lung cancer, lymphoma, or germ cell.

Participant Groups

The study is testing the safety and optimal dose of stereotactic radiosurgery—a precise form of radiation therapy—for treating large brain metastases. It also examines how well it works by assessing quality-of-life and cognitive functions before and after treatment.
