Recruiting studies
- NCT02997709Recruiting
Collecting prostate cancer body marker samples during treatment
This study collects and measures “biomarkers” (measurable signs in the body) from people with prostate cancer who are about to have surgery or radiation. The goal is to understand how prostate cancer behaves during treatment, which may help improve care in the future.
Miami, FloridaAges 30 years+ - NCT02541435Recruiting
Breast cancer radiotherapy side effects study
This study looks at heart and blood-vessel side effects after modern radiation treatment for breast cancer, both soon after and years later. It may help doctors understand who is at risk and how to monitor heart health over time.
ÅlesundAges 30–70 - NCT02468024RecruitingPhase 3
Surgery or focused radiation for early lung cancer
This study compares two treatments—removing only part of the lung (sublobar resection) versus a focused radiation approach (stereotactic ablative radiotherapy)—for early-stage non-small cell lung cancer. It aims to see which option works better with fewer problems for the right patients.
La Jolla, CaliforniaAges 18 years+ - NCT02457962Recruiting
Registry study of outcomes from Mayo radiation treatments
This study collects information about how patients do after radiation treatment and stores some biological samples for future research. It includes people treated at Mayo Clinic Rochester for a cancer-focused (curative) course of radiation.
Rochester, MinnesotaAges Any age - NCT01766297RecruitingPhase 2
Proton radiation after lumpectomy for early breast cancer
This trial studies a type of radiation made with protons to treat only part of the breast after surgery (lumpectomy) for early-stage breast cancer. It may help control the cancer while aiming to reduce radiation to surrounding tissues.
Scottsdale, ArizonaAges 50 years+ - NCT02128906RecruitingPhase 2
Radiation plus chemo choices for throat cancer, using a tumor marker
This trial compares two treatment combinations given with radiation for certain cancers of the throat. It also uses a lab test on the tumor (ERCC1) to help choose and study which treatment works better.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT01803542RecruitingPhase 2
Stereotactic radiation for lung metastases or early lung tumors
This trial studies a precise, high-dose radiation technique (SBRT) to treat tumors in the lungs. It may help control cancer in people who either have early-stage lung cancer that is not fully operable or have limited lung metastases from other cancers.
Toronto, OntarioAges 18 years+ - NCT02016248Recruiting
Radiation “boost” for higher-risk prostate cancer
This trial studies whether adding a stronger “boost” dose of targeted radiation (SBRT) can better control higher-risk prostate cancer. It may help by increasing radiation coverage to the prostate while trying to limit treatment to surrounding areas.
Fountain Valley, CaliforniaAges 18 years+ - NCT01786590Recruiting
Ultrasound biopsy to stage lung cancer before SBRT
This trial looks at using a scope with an ultrasound tip (EBUS-TBNA) to take small tissue samples from lymph nodes to figure out the cancer stage before stereotactic body radiotherapy (SBRT). The goal is to help confirm how far the cancer has spread so SBRT can be planned appropriately.
Toronto, OntarioAges 18 years+ - NCT01985984Recruiting
Predicting outcomes after head and neck radiotherapy
This study looks at how outcomes may be predicted for people with head and neck cancer who receive radiotherapy. It may help doctors better estimate results and tailor follow-up care.
MaastrichtAges 18 years+ - NCT00969111Recruiting
Radiation after prostate surgery for prostate cancer without nodal spread
This trial looks at radiation therapy given after prostate surgery (or if needed later) for prostate cancer where lymph nodes were not involved. It may help patients whose PSA rises or who need additional treatment to reduce the chance the cancer comes back.
Little Rock, ArkansasAges 18 years+ - NCT00026650Recruiting
Understanding Long-Term Effects After Radiation Therapy
This study follows patients who have received radiation therapy to learn about long-term health effects and how the disease progresses over time. By tracking your health over the years, researchers hope to better understand and help future patients manage side effects.
Bethesda, MarylandAges 18–120

Common questions
- Are there clinical trials for radiotherapy?
- Yes. Clin2 currently lists 1,308 recruiting radiotherapy studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a radiotherapy trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a radiotherapy trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
