Re-irradiation planning for tumors near previously treated organs
Part of Cancer clinical trials.
This study tests a more personalized way to plan “re-irradiation,” meaning giving radiation again in an area that was already treated before. It aims to better calculate organ risk to reduce harmful side effects while treating cancer.
Summary written for real people, not researchers, by Clin2.
Who can take part
- Be 18 years or older and be planning definitive (main) or postoperative (after surgery) high-dose radiation that overlaps a previously treated organ at risk
- Have signed consent, prior radiation dose information available, and recent baseline scans (CT, PET/CT, or MRI) within 6 weeks of starting
- Have a confirmed solid cancer diagnosis (with pathology/cytology records) and a treatment team decision that re-irradiation is recommended for your specific target area
- Be able to do required questionnaires, and have most recent cancer treatment side effects improved to mild or moderate (grade 1–2)
- Meet basic health/lab and safety limits (including blood counts and liver/kidney tests) and have an expected life span of at least 6 months
- If you can become pregnant: have a negative pregnancy test and agree to reliable birth control during the radiation course

This trial tests a combination of low-dose radiation, focused high-dose radiation, and an immunotherapy drug (tislelizumab) for people with large, advanced solid tumors that have not responded to standard treatments.
This trial studies giving a second course of radiation to people whose cancer has come back or spread. It aims to see if more radiation can help control the cancer and improve quality of life.
This study tests a new way to plan a second course of radiation for cancer that has returned or spread to a few places. It uses special imaging software to make the treatment more precise and aims to improve outcomes.
This trial studies giving a second course of radiation to tumors in the chest that have come back or not gone away after previous radiation. The goal is to see if a higher dose can be given safely and effectively, while limiting damage to nearby organs.
This trial tests a second, shorter course of radiation to just the area where your cancer was removed, instead of treating the whole breast again. It is for women who have had a new breast cancer in the same breast after previous radiation, to see if this approach is safe and effective.
This Phase 2 study tests whether giving targeted radiation again to the same breast can control a small, local breast cancer that came back after prior whole-breast radiation. It may help some patients avoid or delay further treatment for the breast while carefully checking safety.
