What You Need to Know Before You Apply

What is the purpose of this trial?

This trial seeks to determine the safest dose of a specialized radiation treatment called MRI-guided Stereotactic Body Radiation Therapy (SBRT) for individuals with cancer that has spread to the liver or bowel. The trial focuses on using advanced imaging to deliver precise radiation doses. Suitable candidates have confirmed or suspected cancer in the liver that can be treated with this radiation method and no active brain metastases. Participants will engage in the trial for up to 12 months. As an unphased trial, this study allows participants to contribute to cutting-edge research in radiation therapy.

Do I need to stop taking my current medications to join the trial?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss your specific medications with the trial team to get a clear answer.

What prior data suggests that MRI-guided SBRT is safe for treating bowel and liver metastases?

Research has shown that MRI-guided Stereotactic Body Radiation Therapy (SBRT) is generally well-tolerated for treating various tumors. One study found that even at higher doses, SBRT achieved a 96% success rate over three years, indicating long-term effectiveness.

Further research suggests that using MRI during SBRT enhances the precision of radiation targeting, making the treatment more accurate and potentially safer. Another study confirmed that MRI-guided SBRT is practical, safe, and effective, even for challenging-to-reach tumors.

The current trial aims to determine the safest maximum dose for treating cancer that has spread to the liver. Previous studies provide reassurance, as they already support the safety of this treatment for other conditions.12345

Why are researchers excited about this trial?

Researchers are excited about this trial because it explores a new way to treat liver metastases using SBRT (Stereotactic Body Radiation Therapy) with real-time MRI guidance. Unlike traditional radiation therapies, this method allows for dose escalation, meaning higher, more precise doses can be delivered directly to the tumor while minimizing exposure to healthy tissue. The use of adaptive planning means the treatment can be adjusted on the spot based on real-time images, potentially improving effectiveness and reducing side effects. This approach could offer a more targeted and efficient treatment option for patients with liver metastases.

What evidence suggests that MRI-guided SBRT is effective for treating bowel and liver metastases?

Research has shown that MRI-guided Stereotactic Body Radiation Therapy (SBRT) effectively treats tumors in the abdomen and pelvis, including those that have spread to the liver. In this trial, participants will receive MRI-guided SBRT with dose escalation, aiming for a maximum dose of 80 Gy. MRI guidance allows for more precise radiation targeting, delivering a higher dose to the tumor while protecting nearby organs. This precision can improve outcomes for patients with metastatic tumors. Some studies have found improved survival rates for patients with certain types of these tumors treated with this method. Early results suggest that increasing the radiation dose might enhance outcomes without adding side effects. Overall, this treatment shows promise for safely managing challenging cases of tumor spread.23678

Are You a Good Fit for This Trial?

This trial is for adults with certain types of cancer that has spread to the liver. They must be able to have MRI scans, not have brain metastases or other serious health issues, and their organs must function well. Women who can get pregnant need a negative pregnancy test and agree to use birth control.
