Stereotactic Body Radiation Therapy

Sponsor:

Jonsson Comprehensive Cancer Center

Code:

NCT06436612

Abdominopelvic Sarcomas

Eligibility Criteria

Healthy Volunteers: Not accepted

Interventions

Magnetic Resonance Image and Computed Tomography-Guided Stereotactic Body Radiation Therapy

Study Details

Brief summary:

Recent advances in radiation treatment have allowed for higher doses per treatment to be delivered safely. This study plans to use an MRI-guided linear accelerator to deliver the radiation treatment to ensure that the radiation dose is administered to the cancerous tumor, not the vital body organs.

Potential participants with a sarcoma diagnosis will be referred to Radiation Oncology during this study. If the participant is interested in participating in this study, s/he receives radiation treatment daily for 5 consecutive days except for weekends and holidays. Within 12 weeks of completing the radiation therapy, the participant will have the primary tumor surgically removed. The radiation oncology team will follow the patients for 5 years after completing radiation therapy.
