Stereotactic Radiosurgery for Brain Tumors
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a special type of radiation treatment called stereotactic radiosurgery to evaluate its safety and effectiveness for treating large brain tumors that have spread from other parts of the body. The treatment targets the tumor with high precision, minimizing damage to surrounding healthy tissue. It suits individuals with brain metastases larger than 2 cm but no more than 4 cm in size who have not recently undergone whole brain radiation therapy. This trial does not include those with certain types of cancer, such as small cell lung cancer, or if the tumor is located in the brainstem. Participants must attend all follow-up visits and provide written consent.
As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative therapy.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that stereotactic radiosurgery is safe for treating brain tumors?
Research has shown that stereotactic radiosurgery (SRS) is generally safe and well-tolerated. It uses precise radiation to target brain tumors, causing minimal damage to nearby healthy tissue. A review of 32 studies involving 1,446 patients found that SRS effectively stopped tumor growth in most cases. This well-established procedure plays an important role in treating brain tumors. While some side effects may occur, they are usually mild and temporary. Overall, SRS has a strong safety record, making it a promising option for treating brain metastases.12345
Why do researchers think this study treatment might be promising?
Stereotactic Radiosurgery (SRS) is unique because it delivers highly focused radiation beams to brain tumors with precision guided by CT and MRI imaging. Unlike traditional whole-brain radiation therapy, which can affect healthy brain tissue, SRS targets only the tumor, potentially reducing side effects. Researchers are excited about SRS because it offers a non-invasive alternative to surgery, with the possibility of quicker recovery times and fewer complications. This method allows for treating tumors that are difficult to reach surgically, providing a promising option for patients with complex cases.
What evidence suggests that stereotactic radiosurgery is effective for brain tumors?
Research has shown that stereotactic radiosurgery (SRS), the treatment under study in this trial, effectively treats brain metastases, which are cancerous tumors that have spread to the brain. Studies indicate that SRS controls tumor growth in 73–96% of cases for certain cancers, such as melanoma and kidney cancer. This treatment uses focused x-rays aimed directly at the tumor, protecting the surrounding healthy brain tissue. Due to this precision, SRS serves as a valuable option for managing brain tumors and helps maintain quality of life by preserving normal brain functions.36789

Are You a Good Fit for This Trial?
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
