Can aromatherapy reduce distress before breast cancer radiotherapy?
This trial tests if inhaling certain scents (aromatherapy) can help calm and reduce distress in breast cancer patients just before their first radiotherapy session.
SingaporeAges 21–99 - NCT03649048Recruiting
Weekly low-dose or high-dose cisplatin with radiation for head and neck cancer
This trial compares two cisplatin dosing schedules (weekly low-dose vs higher dose less often) given alongside radiation for certain head and neck cancers. It’s testing which schedule works well while keeping side effects manageable during planned, curative-intent radiation.
Hamilton, OntarioAges 18 years+ - NCT03830788Recruiting
Radiation options for early prostate cancer-related erections
This study compares two radiation treatments—seed brachytherapy and stereotactic body radiotherapy—to see which better preserves erections in men with early- to mid-risk prostate cancer. It’s designed to help patients understand how different curative radiation choices can affect sexual function.
AlbiAges 18 years+ - NCT06691776Recruiting
Adaptive radiotherapy for five cancer types
This trial tests whether a newer type of daily CT scan (CBCT-guided adaptive radiotherapy) can safely and accurately deliver radiation to cancers of the prostate, cervix, bladder, lung, or head and neck. The goal is to better target the tumor and reduce side effects.
AmsterdamAges 18 years+ - NCT06727617RecruitingPhase 2
Serplulimab with chemoradiation for high-risk cervical cancer
This trial tests adding an immunotherapy drug (serplulimab) to standard chemoradiation after cervical cancer surgery. It is for patients with at least two high-risk features, like lymph node spread or deep invasion, to see if it helps prevent the cancer from coming back.
Tianjin, Tianjin MunicipalityAges 18–65 - NCT06719700RecruitingPhase 2
Chemo-radiation with two drugs for limited-stage small cell lung cancer
This trial tests combining standard chemotherapy with radiation (chemoradiotherapy) plus two additional drugs, toripalimab and surufatinib, for people with limited-stage small cell lung cancer. The goal is to see if this combination improves outcomes.
Guangzhou, GuangdongAges 18–75 - NCT05265208RecruitingPhase 2
Radiation plus chemo after liver surgery for bile duct cancer
This trial studies giving a special internal radiation treatment along with capecitabine (a chemotherapy) for liver cancer related to bile ducts, after planned surgical removal. It may help improve control of the cancer in cases where surgeons think the edges of the removed tumor may be too close.
Rennes, Brittany RegionAges 18 years+ - NCT05203250Recruiting
Registry for people treated with heavy particles at CNAO
This registry collects information from people who received heavy particle treatments at the CNAO center. It helps researchers understand outcomes over time, as long as you can understand the study and agree in writing.
PaviaAges Any age - NCT06715501Enrolling by invitation
Testing cadonilimab with chemo and radiation for advanced esophageal cancer
This trial tests a new drug (cadonilimab) combined with standard chemotherapy and radiation for people with advanced esophageal squamous cell carcinoma that cannot be surgically removed. The goal is to see if this combination works better than current treatments.
Ningbo, ZhejiangAges 18–75 - NCT06250972RecruitingPhase 3
Radiotherapy for advanced pancreatic cancer with normal CA19-9 after chemo
This trial tests whether giving radiotherapy to the pancreas can help people with advanced pancreatic cancer whose CA19-9 level has dropped to normal after chemotherapy. It's for patients whose cancer is still locally advanced (hasn't spread to distant organs).
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05944913Recruiting
Testing a special wound dressing after sarcoma tumor removal
This trial compares two types of wound dressings after surgery for soft-tissue sarcoma (STS) that has had radiation therapy. It aims to see whether one dressing helps your wound heal better after tumor removal.
Nantes, Pays de LoireAges 18 years+ - NCT06704659Recruiting
Repeated radiation for recurrent breast cancer
This study tests giving a second round of radiation therapy to women whose breast cancer has come back in the same breast, at least 3 years after their first radiation. It may be an option for women 55 and older who have a small, local recurrence that can be removed with surgery.
HelsinkiAges 55 years+ - NCT03672721RecruitingPhase 1/Phase 2
Carboplatin with radiation for returning glioblastoma
This Phase 1/2 study tests a combination of carboplatin chemotherapy with radiation for glioblastoma that has come back. It aims to shrink or control the tumor after standard treatment has already been used.
Sherbrooke, QuebecAges 18 years+ - NCT06686771RecruitingPhase 3
Radiation for limited growth in advanced lung cancer on immunotherapy
This trial tests whether giving high-precision radiation to a few spots that are growing during immunotherapy (with or without chemotherapy) can help people with advanced lung cancer. It aims to see if treating these limited areas of resistance can extend the time the cancer stays under control.
Phoenix, ArizonaAges 18 years+ - NCT06687421Recruiting
Precision medicine for high-risk prostate cancer
This study aims to use precision medicine (tailored treatment based on your specific cancer) for men at high risk of prostate cancer. It may help doctors choose the best treatment for you.
UmeåAges 18 years+ - NCT06220435Recruiting
Radiation therapy for very high-risk localized prostate cancer
This trial tests radiation therapy for men with very high-risk prostate cancer that hasn't spread. It aims to see if targeting the tumor with radiation can help control the cancer in this highest risk group.
LundAges 18 years+ - NCT06692556RecruitingPhase 3
Radiation vs monitoring for high-risk skin cancer
This trial compares two strategies after surgery for a type of skin cancer (cutaneous squamous cell carcinoma) that has a high chance of coming back. One strategy gives radiation therapy to the area, while the other just watches and checks for any signs of recurrence. The goal is to see if radiation can prevent the cancer from returning.
Le Puy-en-Velay, Auvergne-Rhône-AlpesAges 18 years+ - NCT04442724Recruiting
MRI and bladder marker planning to guide bladder chemoradiation
This trial uses special MRI scans and tiny markers placed in the bladder to better plan bladder chemoradiation. The goal is to help target treatment more accurately and improve how well it can be delivered.
Los Angeles, CaliforniaAges 18 years+ - NCT06676449RecruitingPhase 3
A study on radiation-sparing treatment for advanced esophageal cancer
This trial tests a new approach for advanced esophageal cancer that combines targeted radiation, immunotherapy, and chemotherapy. It aims to see if skipping radiation to certain lymph nodes can improve outcomes while reducing side effects.

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.
