Stereotactic Radiation for Growing/Changing Brain Metastases With Same-Day Radiation Planning and Treatment With Margin Reduction
What this study is about
The goal of this study is to evaluate the feasibility and effectiveness of same-day radiation planning and treatment. The study will shorten the time interval between radiation planning (radiation mapping) and radiation treatment. The intent of this shorter time interval is to increase the likelihood that the brain metastases being treated remain fully within the high-dose radiation fields.
View original scientific description
The goal of this study is to evaluate the feasibility and effectiveness of same-day radiation planning and treatment. The study will shorten the time interval between radiation planning (radiation mapping) and radiation treatment. The intent of this shorter time interval is to increase the likelihood that the brain metastases being treated remain fully within the high-dose radiation fields. Participants will be randomized to receive brain-directed stereotactic radiation with a 1mm margin or 0mm margin, have their simulation/radiation planning imaging on the same day that brain-directed stereotactic radiation is delivered, and have repeat simulation/radiation planning scans during the course of treatment if more than 2-3 days have elapsed since the most recent scans.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Participants must have a biopsy proven solid malignancy with at least one intact, residual or recurrent, intracranial lesion radiographically consistent with or pathologically proven to be a brain metastasis meeting one of the following criteria:
- Growth of 1.0mm per week or more, on average, based on the two most recent brain MRIs preceding study enrollment
- Abutment, to within 1.0cm, of a region of intracranial edema
- Proximity (within 5.0cm) to a surgical cavity created within 30 days of enrollment
- Proximity (within 5.0cm) to another source of physical displacement
- Age of at least 18 years
- Karnofsky performance status of at least 60
- Estimated survival of at least 3-6 months in the opinion of the enrolling clinician and/or study PI
- Ability to understand and the willingness to sign a written informed consent document by either ink on paper or a DF/HCC approved eConsent medium
Exclusion criteria
- Participants who cannot tolerate a brain MRI
- Patients who cannot receive gadolinium
- Participants with end stage renal disease
- Participants with widespread, definitive leptomeningeal disease
- Pregnant women are excluded from this study because of the potential deleterious effects of gadolinium on the developing fetus. Because there is an unknown but potential risk for adverse events in nursing infants, women who are breastfeeding are not eligible for this study as well

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
