MilanAges Any age - NCT04603209Recruiting
Check-in registry for radiation during breast-conserving surgery
This registry study tracks people with early-stage, single-area breast cancer to understand outcomes when radiation is given during breast-conserving surgery. It may help doctors improve treatment planning for patients like you.
Santa Monica, CaliforniaAges 18 years+ - NCT06356779Recruiting
Studying local treatment for a few cancer spots
This study is for people with solid tumors that have spread to a few spots (5 or fewer) in the body. It tests whether using a focused treatment like radiation or ablation on those spots can help control the cancer long-term.
Copenhagen, Capital Region of DenmarkAges 18 years+ - NCT06385717Recruiting
ESD plus chemoradiotherapy for early esophageal cancer
This study tests whether combining radiation and chemotherapy after endoscopic removal of early-stage esophageal cancer can effectively treat the cancer without needing surgery. It may be an option for people whose cancer was removed with ESD but who want to avoid additional surgery.
Hangzhou, ZhejiangAges 18–75 - NCT06151743RecruitingPhase 2
Testing drug combo before throat cancer surgery
This trial tests a new combination of drugs (an immunotherapy called a PD-1 inhibitor, cetuximab, and platinum chemotherapy) given before surgery for advanced throat cancer that requires removing the voice box. The goal is to see if this treatment shrinks the tumor and improves outcomes.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06282497Recruiting
New radiation technique to reduce dry mouth in nasopharyngeal cancer
This trial compares a new radiation technique designed to reduce dry mouth (xerostomia) with standard radiation for people with nasopharyngeal cancer. It aims to see if the new approach can protect saliva glands while still treating the cancer effectively.
Zhongshan, GuangdongAges 18–70 - NCT06190782RecruitingPhase 3
Local therapy for limited metastatic esophageal cancer
This trial tests whether adding targeted radiation or other local treatments can help people with esophageal cancer that has spread to only a few spots (up to 4) after they've been treated with a PD-1 inhibitor. It aims to control the cancer better and improve outcomes.
ShanghaiAges 18 years+ - NCT03914378Recruiting
Study how radiation and cisplatin affect hearing in head and neck cancer
This study looks at how radiotherapy, and possibly cisplatin chemotherapy, affect hearing in people treated for head and neck cancer. It may help doctors better predict hearing side effects and plan hearing monitoring or prevention.
ManchesterAges 18 years+ - NCT05727605Recruiting
Thinking changes after radiotherapy for brain and skull-base tumors
This trial studies how radiotherapy affects memory and thinking in adults with certain brain or skull-base tumors. It may help doctors understand who is most likely to have thinking changes and how to monitor or support patients.
GhentAges 18 years+ - NCT06405217Recruiting
Recombinant TSH for radioactive iodine therapy in thyroid cancer
This trial tests whether a medicine called recombinant human thyroid stimulating hormone (rhTSH) can help prepare your body for radioactive iodine (131I) treatment, which aims to destroy any remaining or spreading thyroid cancer cells. It may be a good option if your thyroid cancer has come back or spread and you are able to have radioactive iodine therapy.
Nanjing, JiangsuAges 18–75 - NCT05664464RecruitingPhase 1/Phase 2
Glutamate drugs for newly diagnosed brain tumor treatment
This Phase 1/2 study tests whether “glutamate inhibitor” medications can be safely added for newly diagnosed glioblastoma, and how they affect treatment outcomes. It’s designed for adults who will also receive the standard chemo‑radiation plan with temozolomide.

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.
