Recruiting studies
- NCT06201078RecruitingPhase 2
Second radiation for prostate cancer that returns locally
This trial tests a second round of precise, high-dose radiation (stereotactic body radiotherapy) for men whose prostate cancer has come back only in the prostate after their first radiation treatment. It aims to control the recurrence with fewer side effects.
GliwiceAges 18–80 - NCT07313241RecruitingPhase 2
Salvage radiation with hormone therapy for prostate cancer recurrence
This trial tests how well salvage radiation therapy works for prostate cancer that has come back after surgery. It looks at whether adding hormone therapy based on PSA response improves outcomes.
Dallas, TexasAges 18 years+ - NCT07299812Recruiting
Protecting the heart during breast cancer radiation
This trial tests whether a special breathing technique (called Active Breathing Coordinator) can help keep radiation away from the heart while treating breast cancer with radiation therapy. If you can hold your breath briefly during treatment, this might lower the risk of heart damage.
Pavia, LombardyAges 18 years+ - NCT07284992RecruitingPhase 2
Comparing short vs long radiation with immunotherapy for rectal cancer
This trial tests whether a short course of radiation followed by an immunotherapy drug (PD-L1 inhibitor) plus chemotherapy works as well as or better than a longer radiation course for locally advanced rectal cancer. The goal is to shrink tumors before surgery.
Jinan, ShandongAges 18–80 - NCT07277764RecruitingPhase 2
Radiation and immunotherapy for returning nasopharyngeal cancer
This trial tests a combination of high and low dose radiation plus an immunotherapy drug (PD-1 inhibitor) for people whose nasopharyngeal cancer has come back after previous treatment. The goal is to see if this approach can be more effective while reducing side effects.
Nanchang, JiangxiAges 18–75 - NCT07276360RecruitingPhase 2
Short-course radiation for advanced cervical cancer in Uganda
This trial tests a shorter course of radiation therapy (fewer, higher-dose sessions) for women in Uganda with locally advanced cervical cancer. The goal is to see if this approach works as well as or better than standard radiation while reducing treatment time.
Kampala, KampalaAges 18 years+ - NCT04506008RecruitingPhase 2
Radiation followed by surgery for soft tissue sarcoma
This trial tests a treatment plan where you first get a shorter (hypofractionated) course of radiation and then have surgery to remove the tumor. It may help control the cancer locally in certain soft tissue sarcomas and improve surgical outcomes.
Nashville, TennesseeAges 18 years+ - NCT07256158RecruitingPhase 3
Reducing radiation for early unfavorable Hodgkin lymphoma
This trial tests whether a lower dose of radiation, guided by PET scans, is safe and effective for people with early-stage but unfavorable Hodgkin lymphoma. It aims to reduce side effects while keeping the treatment strong.
AlessandriaAges 18 years+ - NCT07239466RecruitingPhase 2
Ketone supplement with radiation and chemo for rectal cancer
This study tests a combination of a special diet supplement (beta-hydroxybutyrate), short radiation therapy, immunotherapy, and chemotherapy before surgery for locally advanced rectal cancer. The goal is to see if this approach helps shrink the tumor and improve treatment outcomes.
Wuhan, HubeiAges 18–75 - NCT07235319RecruitingPhase 3
Immediate vs delayed radiation after chemo-immunotherapy for metastatic NPC
This trial tests whether giving radiation therapy to the main tumor right after chemo-immunotherapy is better than waiting until the cancer comes back, in people with newly diagnosed metastatic nasopharyngeal cancer. It aims to see which approach helps you live longer and have fewer side effects.
Guangzhou, GuangdongAges 18–70 - NCT06752239RecruitingPhase 3
Optimizing radiation to protect thyroid in nasopharyngeal cancer
This trial tests a way to adjust radiation therapy to better protect the thyroid gland during treatment for nasopharyngeal carcinoma. It aims to reduce thyroid damage while still effectively treating the cancer.
Nanchang, JiangxiAges 18–70 - NCT07189598Recruiting
High-dose radiation therapy for high-risk prostate cancer
This trial tests whether giving a higher dose of radiation therapy (called SBRT) can safely and effectively treat high-risk prostate cancer that hasn't spread. It's for men who have not yet been treated for their cancer.
RennesAges 18 years+ - NCT07186621RecruitingPhase 3
Testing immunotherapy or chemoembolization after liver cancer surgery
This trial compares two treatments after liver cancer surgery to see which better prevents the cancer from coming back. You may be eligible if your surgery had a narrow margin and you have certain risk factors, like a tumor over 5 cm or high AFP levels.
BeijingAges 18–80 - NCT07182565RecruitingPhase 1/Phase 2
Short radiation plus chemotheapy and immunotherapy before surgery for junction cancer
This trial tests a combination of shortened radiation therapy, immunotherapy, and chemotherapy given before surgery for cancer at the junction of the esophagus and stomach. The goal is to see if this approach is safe and improves outcomes.
Xiamen, FujianAges 18 years+ - NCT07165847RecruitingPhase 2
Combination therapy before surgery for gastric cancer
This trial tests a combination of radiation, chemotherapy, and two immunotherapy drugs before surgery for people with resectable gastric or gastroesophageal junction cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
Chongqing, Other (Non U.s.)Ages 18 years+ - NCT06933199Recruiting
Focused radiation before brain tumor surgery
This study tests giving a single, precise dose of radiation to a brain metastasis just before surgery, to see if it helps control the tumor better without extra side effects. It’s for people who are already planning surgery for a medium-to-large brain tumor that started from another cancer.
Ostrava, Moravian-Silesian RegionAges 18 years+ - NCT07150949RecruitingPhase 2
Comparing two radiation schedules with chemotherapy and immunotherapy for rectal cancer
This study tests two different radiation regimens (long-course vs. short-course) combined with chemotherapy (CAPOX), an immunotherapy drug (PD-1 antibody), and a COX-2 inhibitor for people with MSS locally advanced rectal cancer. The goal is to see which approach works better in shrinking the tumor before surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07139990RecruitingPhase 1
Personalized radiotherapy for lung, brain, sarcoma, or head and neck cancers
This trial tests whether giving personalized radiotherapy alongside standard treatments can better control several types of cancer: small cell lung cancer, brain metastases, soft tissue sarcoma, and head and neck cancer. It aims to see if this approach helps patients live longer without their cancer growing or coming back.
Dallas, TexasAges 18 years+ - NCT07116213Recruiting
Shorter radiation after surgery for high-risk endometrial cancer
This trial studies a new type of radiation therapy (called online adaptive radiotherapy) given in shorter, higher daily doses after surgery for high-risk endometrial cancer. The goal is to see if this approach is safe and effective for reducing side effects while still controlling the cancer.
Beijing, Beijing MunicipalityAges 18–70 - NCT05439278RecruitingPhase 3
Radiation schedules plus temozolomide for elderly glioblastoma
This study compares a standard radiation schedule versus a shorter, higher-dose radiation schedule, both with the chemotherapy medicine temozolomide, in older adults with newly diagnosed glioblastoma. It aims to see which approach works better and is practical for people age 70 and older.
SeoulAges 70 years+ - NCT05192876Recruiting
Review of outcomes and side effects during radiation treatment
This study collects information about results and side effects from people receiving radiation therapy at a specific hospital. It may help improve how radiation treatment is planned and monitored in the future.

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.
