This trial tests whether giving radiation therapy before surgery helps people with locally advanced breast cancer that hasn't been removed with chemotherapy. It may offer a new option for those who cannot have surgery right away.
Shanghai, Shanghai MunicipalityAges 18–70 - NCT05584267RecruitingPhase 2
Immunotherapy plus targeted brain radiation for lung cancer
This Phase 2 trial studies whether giving immunotherapy along with a precise form of brain radiation can control brain metastases from non-small cell lung cancer. It may help by shrinking or stabilizing spots in the brain while your body’s immune system is also activated.
Changsha, HunanAges 18 years+ - NCT05603078Recruiting
Breast cancer surgery with a tumor-bed boost and standard radiation
This study looks at whether adding extra targeted radiation to the tumor area before breast-conserving surgery, then using modern breast surgery techniques and whole-breast radiation afterward, improves outcomes for early-stage breast cancer. You may be offered a treatment plan designed to better treat the area where the tumor was removed.
Beijing, Beijing MunicipalityAges Up to 55 years - NCT05692674RecruitingPhase 2
Proton radiation after breast surgery with implant reconstruction
This trial studies a type of radiation made with proton beams given after mastectomy and implant reconstruction to lower breast cancer coming back. It’s for people who need additional (adjuvant) radiation and have not had prior radiation to the chest or breast.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT05733156Recruiting
Low-dose radiation to trigger whole-body cancer effects
This trial tests whether giving a low dose of radiation to one spot can help shrink cancer in other, untreated areas (the “abscopal effect”) in people with multiple metastases. It may help by boosting the body’s response to stereotactic body radiotherapy (focused high-dose radiation) for tumors outside the brain.
SeoulAges 19 years+ - NCT05760391Recruiting
Check anti-PD-1 therapy plus radiation for advanced esophageal cancer
This trial studies whether adding an anti-PD-1 immunotherapy (with chemotherapy) together with radiation can help people with advanced esophageal squamous cell cancer. It’s for cases where surgery or standard definitive chemoradiation can’t be done, or the cancer has spread to distant sites.
ShanghaiAges 18–80 - NCT05762900RecruitingPhase 2
Shorter breast radiation after surgery for low-risk breast cancer
This Phase 2 trial tests a shorter, focused radiation treatment after breast surgery, either alone or with an extra targeted boost. It’s for people with low-risk breast cancer and no spread to distant organs, aiming to keep results while reducing treatment time and side effects.
BeijingAges 35 years+ - NCT05765812RecruitingPhase 1/Phase 2
Debio 0123 with temozolomide for recurrent or new glioblastoma
This early-phase study tests Debio 0123 (an anticancer medicine) combined with temozolomide, and for newly diagnosed patients also with radiation. It aims to see whether this treatment combination can slow or control glioblastoma in adults.
Chicago, IllinoisAges 18 years+ - NCT05781217RecruitingPhase 3
Short vs longer hormone therapy after salvage prostate radiation
This trial compares two lengths of hormone treatment (androgen deprivation therapy) given around “salvage” radiation after prostate surgery for rising PSA. It aims to see which schedule works best to control prostate cancer while keeping side effects manageable.
L'Hospitalet de Llobregat, BarcelonaAges 18 years+ - NCT05783908Recruiting
Self-guided breathing help during MRI-guided radiotherapy for moving tumors
This study tests whether a self-guidance approach for breathing can improve radiotherapy sessions when the tumor moves during breathing and is treated with an MRI-guided machine. It may help make treatments more accurate and easier to follow during each session.
Dijon, Côte d'OrAges 1.5 years+ - NCT05804916RecruitingPhase 2/Phase 3
Tracking-guided radiation for left breast after surgery
This trial tests a radiation planning and monitoring approach that uses surface tracking and breathing control to deliver large-area radiation more accurately for left breast cancer. It may help improve how consistently treatment is delivered while accounting for chest movement.
Beijing, Beijing MunicipalityAges 18–70 - NCT05854823Recruiting
Reduced radiation after surgery for advanced head and neck cancer
This trial looks at whether giving less (de-escalated) radiation after surgery is as effective and safer for people with locally advanced head and neck squamous cell carcinoma who had a strong response to treatment before surgery. If you had no remaining cancer or only very small amounts of cancer left in the surgical specimen, this approach may help reduce side effects while keeping control of the disease.
Zhuhai, GuangdongAges 18–70 - NCT05883800Recruiting
Total treatment with tailored radiation for advanced rectal cancer
This study tests a “total neoadjuvant” approach—chemotherapy first, then radiation—using adaptive (tailored) radiation planning for people with locally advanced rectal cancer. It may help improve tumor control while adjusting the radiation based on how your cancer and anatomy respond.
BergenAges 18 years+ - NCT05887284Recruiting
Low-dose radiation study for osteoarthritis pain relief
This study tests whether giving a small amount of radiation to an osteoarthritis joint can improve symptoms. It’s designed for people who are newly starting this kind of treatment and can return for follow-up visits.
Erlangen, BavariaAges 39 years+ - NCT05933876Recruiting
Radiation study for limited spread cancer
This trial looks at whether giving radiation treatment to tumors in people with a limited number of metastases can help control the cancer. It is for adults with certain cancer types that have spread to specific organs, and who can manage daily activities with little or no help.
Albacete, AlbaceteAges 18 years+ - NCT05941741RecruitingPhase 3
Tested low-dose radiation plus cadonilimab for nasopharyngeal cancer
This Phase 3 trial studies whether adding low-dose radiation to cadonilimab (an immune therapy) can improve outcomes for people newly diagnosed with a specific type and stage of nasopharyngeal cancer. If you’re eligible, it may offer a new treatment approach and helps researchers confirm whether it works best.
Guangzhou, GuangdongAges 18–70 - NCT05947513Recruiting
Curcumin pills alongside palliative radiation for advanced cervical cancer
This trial studies whether taking curcumin (from turmeric) during palliative radiation can improve outcomes for people with advanced cervical cancer. It’s meant for patients who are receiving radiation for symptom relief without chemotherapy.
Addis AbabaAges 18 years+ - NCT05965531RecruitingPhase 2
TAS-102 plus radiation before surgery for rectal cancer
This trial studies whether adding TAS-102 (a chemotherapy medicine) to radiation given before treatment improves outcomes for certain locally advanced rectal cancers. It may help by trying to shrink the tumor before the next steps of care.
Guangzhou, GuangdongAges 18–70 - NCT05980715RecruitingPhase 3
Comparing immunotherapy to radiation after successful treatment for head and neck cancer
This trial looks at whether giving an immunotherapy drug (a PD-1 inhibitor) after surgery is better than giving radiation therapy for people with advanced head and neck cancer who had a complete response to chemotherapy and immunotherapy before surgery. The goal is to prevent the cancer from coming back.
Guangzhou, GuangdongAges 18–65 - NCT05984576Recruiting
Chemo and radiation for recurrent rectal cancer after prior pelvic radiation
This study looks at combining total neoadjuvant therapy (chemotherapy and radiation) for rectal cancer that has come back in the pelvis after earlier radiation. It aims to see if this treatment approach can help control the disease and improve outcomes in patients with limited spread that can potentially be removed or treated.
RomeAges 18 years+ - NCT05996367Recruiting
