What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new method of delivering radiation treatment to individuals with sarcoma, a cancer often affecting the abdomen or pelvis. Advanced imaging techniques precisely target the tumor, minimizing radiation damage to healthy organs. Participants will receive a daily radiation dose for five days, followed by surgical tumor removal within 12 weeks. The trial seeks participants diagnosed with surgically removable sarcoma who have not received prior radiation in the same area. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to significant advancements in sarcoma care.

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 MRI and CT-guided radiation therapy is safe for treating sarcoma?

Research has shown that using MRI and CT scans to guide stereotactic body radiation therapy (SBRT) is generally safe for treating certain cancers. In studies with other types of cancer, patients have tolerated this treatment well, experiencing few serious side effects. One study found that using MRI to guide radiation therapy was feasible and caused minimal harm to the body. Another study demonstrated that SBRT for soft tissue cancers was both safe and effective.

This trial is in Phase 2, indicating that earlier studies have already shown the treatment to be somewhat safe. This phase focuses more on evaluating the treatment's effectiveness and monitoring for any side effects. Although the treatment remains under study, existing research suggests it is generally safe for people. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatment for sarcoma?

Most treatments for sarcoma involve surgery followed by radiation therapy or chemotherapy. However, MRI + CT-guided radiation therapy is unique because it combines advanced imaging techniques to precisely target the tumor with stereotactic body radiation therapy (SBRT). This method allows for high doses of radiation to be delivered directly to the cancer cells while minimizing damage to surrounding healthy tissues. Researchers are excited about this approach because it could potentially improve treatment outcomes by increasing the accuracy and effectiveness of radiation therapy, especially in the pre-operative setting.

What evidence suggests that MRI and CT-guided radiation therapy is effective for sarcoma?

Research has shown that using MRI and CT scans to guide stereotactic body radiation therapy (SBRT) holds promise for treating sarcomas. In this trial, participants will receive MRI or CT-guided SBRT before surgery. Studies have found SBRT effective for cancer that has spread to the lungs, with some patients experiencing long-lasting benefits. Additionally, MRI-guided radiation can prevent cancer from spreading in the treated area. Previous results suggest that SBRT is safe and effective for certain soft tissue cancers. These findings support the potential of MRI and CT-guided SBRT to precisely target tumors, reducing harm to nearby healthy tissues. ^{2 5 6 7 8}

Are You a Good Fit for This Trial?

This trial is for individuals with a diagnosis of sarcoma, specifically in the abdominopelvic region. Participants will undergo radiation therapy daily for 5 days and have their primary tumor surgically removed within 12 weeks after completing radiation. They'll be followed up for 5 years.

Published Research Related to This Trial

Magnetic Resonance-guided Radiation Therapy (MRgRT) shows promise for safely delivering high doses of radiation to oligometastatic tumors while protecting surrounding healthy tissues, thanks to its superior imaging capabilities and real-time monitoring.

Despite its potential, further clinical evidence is needed to address technical challenges and ensure safety in the MRI environment, highlighting the importance of ongoing research in this innovative treatment approach.

The study demonstrated that a one-stop-shop (OSS) procedure for MR-guided Stereotactic Ablative Radiotherapy (SABR) in lung cancer patients is feasible, with all 10 participants completing the treatment in a single day and reporting high satisfaction levels.

The accuracy of the treatment delivery was high, with the tracking system covering 78% to 100% of the tumor volume during radiation, indicating effective real-time monitoring and minimal impact from system latency.

In a study of 3410 patients treated with SBRT for localized prostate cancer, only 4.75% received treatment planning using CT alone, and this group showed tolerable toxicity with only two cases of Grade 3+ toxicity reported.

Quality of life assessments indicated temporary declines in urinary and bowel function after treatment in the CT group, but these returned to baseline levels in follow-up, suggesting that CT-based planning is a safe alternative for patients who cannot undergo MRI.
