This study tests MRI scanning and image analysis methods to help doctors plan radiation treatment more accurately and assess how well it’s working. You might help improve how MRI is used for radiation planning and follow-up.
Basking Ridge, New JerseyAges 18 years+ - NCT01492972RecruitingPhase 3
Lighter radiation, with or without hormone suppression
This Phase 3 trial tests whether giving a smaller amount of radiation (“hypo-fractionated” means fewer, larger sessions) can work as well as standard approaches for intermediate-risk prostate cancer. It also compares adding hormone therapy (“androgen suppression”) to radiation versus using radiation alone.
Scottsdale, ArizonaAges 18 years+ - NCT01696721Recruiting
Pediatric radiation therapy registry for children under 22
This study is a registry that collects information from children and teens who receive radiation therapy at participating hospitals. It helps researchers learn how radiation is used in pediatrics and may improve future care.
Palo Alto, CaliforniaAges Up to 21 years - NCT06487481RecruitingPhase 1
Radiation before surgery for recurrent adrenal cancer
This trial tests whether giving radiation before surgery helps people with adrenal cancer that has come back after previous treatment. It aims to see if this approach can improve outcomes for patients who can have surgery at the NIH.
Bethesda, MarylandAges 18–120 - NCT04775355Recruiting
Track urine and gut changes during prostate cancer treatment
This study looks at how your urine and gut (intestine) microbes change while you undergo prostate cancer treatments, including hormone therapy (androgen deprivation) and/or radiation. The goal is to better understand these biological changes, which may help improve future treatment planning.
Duarte, CaliforniaAges 18 years+ - NCT05901519RecruitingPhase 2
Prednisone to protect the liver during focused radiation for liver cancer
This trial tests whether prednisone (an anti-inflammatory steroid) can help protect the liver in people with hepatocellular carcinoma who are getting stereotactic body radiation therapy. It may reduce liver stress from radiation and help you tolerate treatment safely.
Ann Arbor, MichiganAges 18 years+ - NCT03671252RecruitingPhase 3
Chemotherapy before surgery for rectal cancer vs chemo with radiation
This Phase 3 trial compares two treatment plans given before rectal surgery. It tests whether stronger chemotherapy alone works better than chemotherapy pills plus long-term radiation to improve outcomes for locally advanced rectal cancer.
Guangzhou, GuangdongAges 18–75 - NCT04316039RecruitingPhase 2/Phase 3
Radiation alone or with temozolomide for brain tumor after surgery
This trial compares standard radiation therapy versus radiation plus a chemotherapy medicine called temozolomide in people with a newly diagnosed low-grade (WHO grade II) brain glioma after surgery. It’s designed to see if adding temozolomide improves outcomes while managing side effects.
Chengdu, SichuanAges 18–70 - NCT04220749RecruitingPhase 2
Radiation vs mouth surgery for HPV-negative throat cancer
This Phase 2 trial compares two standard cancer treatments—radiation or surgery through the mouth—for HPV-negative oropharyngeal throat cancer. It aims to find out which approach works better while keeping side effects and quality of life acceptable.
London, OntarioAges 18 years+ - NCT04822077Recruiting
Proton beam treatment for thymus tumors
This trial studies proton radiotherapy (a type of radiation) for cancers of the thymus, like thymoma or thymic carcinoma. It may help improve tumor control while limiting radiation exposure to nearby organs.
Umeå, NorrlandAges 18 years+ - NCT03961776Recruiting
MRI to monitor treatment response in rectal cancer
This trial tests whether an MRI scan done during chemoradiation can help doctors track how rectal cancer treatment is working. It may improve how they measure response early so treatment planning can be better tailored.
Los Angeles, CaliforniaAges 18 years+ - NCT04060706Recruiting
Testing new computer tools for radiation treatment planning
This study tests how well new computer methods (called algorithms and machine learning) can support radiation therapy decisions. You might benefit by helping improve how radiation is planned and checked, especially for cancers treated with curative-intent therapy.
Cambridge, CambridgeshireAges 18 years+ - NCT05595590RecruitingPhase 2
Radiation plus immunotherapy for recurrent head and neck cancer
This study tests whether adding an immunotherapy medicine called tislelizumab to radiation can better control recurrent (coming back) head and neck squamous cell cancer. It is aimed at people whose cancer can’t be fully removed by surgery or can’t be safely removed.
Chengdu, SichuanAges 18–75 - NCT03836196Recruiting
Improve treatment for advanced prostate cancer with careful planning
This study looks at how to best plan and deliver treatment for men with advanced local prostate cancer. It may help find the most effective approach while keeping side effects manageable.
Vancouver, British ColumbiaAges 18 years+ - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT05136326RecruitingPhase 2
Pre-surgery chemo-radiation for rectal cancer without MGMT
This trial studies whether adding two chemotherapy medicines (capecitabine and temozolomide) to standard pre-surgery chemo-radiation can work better for people with locally advanced rectal cancer that has a specific tumor marker pattern (MGMT “silenced”) and is mismatch-repair proficient (MSS). It aims to shrink the tumor before surgery and improve cancer control.
MilanAges 18 years+ - NCT04842006Recruiting
Personalized treatment plan for rectal cancer before and after surgery
This trial looks at a personalized treatment approach for rectal cancer. It aims to guide the best chemotherapy and (if needed) radiotherapy before and after surgery, based on scans and specific test results.
