Commack, New YorkAges 18 years+ - NCT05301881RecruitingPhase 2
Keep the same treatment after limited metastatic growth
This study tests whether continuing your current systemic (whole-body) therapy is safe and helpful when only 1–2 metastatic spots start growing. It also checks whether adding local treatment (such as radiation or ablation) to those spots can better control the cancer.
AlkmaarAges 18 years+ - NCT05313815Recruiting
Test a stronger prostate radiation boost for high-risk prostate cancer
This trial studies whether giving a moderate “boost” dose of radiation to the prostate—along with radiation to the pelvic area—can better control high-risk localized prostate cancer. You may benefit if you have high-risk disease and can safely receive radiation.
Toronto, OntarioAges 18 years+ - NCT05316922RecruitingPhase 3
Lowering thyroid hormone during radiation to prevent low thyroid
This study tests whether using treatment to keep thyroid-stimulating signals low during radiation to the thyroid area can help prevent a treatment-related drop in thyroid function in children. It is aimed at kids with certain cancers whose radiation plan includes thyroid tissue.
MilanAges Any age - NCT05327686RecruitingPhase 2
Adding focused radiation to immunotherapy for kidney cancer
This Phase 2 trial studies whether adding focused, high-precision radiation to immunotherapy helps people with advanced kidney cancer (that cannot be removed by surgery or has spread). It aims to improve cancer control by combining two treatment approaches.
Birmingham, AlabamaAges 18 years+ - NCT05337631Recruiting
Care patterns for older people receiving head and neck radiation
This study looks at special ways of providing care for people age 65 and older with certain head-and-neck cancers when they receive radiation (with or without chemotherapy). It aims to understand how care should be organized to better support older patients during treatment.
Baltimore, MarylandAges 65 years+ - NCT05340491RecruitingPhase 3
Radiation plus immunotherapy for repeat nasopharyngeal cancer
This trial studies whether adding an anti–PD-1 immunotherapy to standard chemoradiotherapy can control nasopharyngeal cancer that has come back in the local area. It may help patients live longer or have the cancer respond better compared with chemoradiotherapy alone.
Guangzhou, GuangdongAges 18–70 - NCT05344235Recruiting
Study of very short radiation schedules for prostate cancer
This observational study looks at how well men with localized prostate cancer do when treated with an unusually short radiation approach. It may help doctors understand which patients benefit most by tracking outcomes and imaging over time.
Leuven, Vlaams BrabantAges Any age - NCT05348486Recruiting
Adaptive radiation planning using FMISO imaging for head and neck cancer
This trial tests a way to personalize radiation treatment using a special scan (FMISO) to improve targeting in certain head and neck cancers. It is designed for people who are newly diagnosed and ready for standard curative (definitive) chemoradiation or faster radiation schedules.
BrnoAges 18 years+ - NCT05346367Recruiting
Targeted brain radiation to improve treatment benefit and limit side effects
This study tests a more targeted form of stereotactic (precise) brain radiation for people with brain metastases from large cell cancer. It aims to improve the balance between effectiveness and side effects by carefully focusing where the radiation goes.
Leidschendam, South HollandAges 18 years+ - NCT05352178RecruitingPhase 3
Targeted treatment for few-spread prostate cancer spots
This Phase 3 trial tests whether treating only a small number of prostate cancer metastases can help people with “oligorecurrent” (limited repeat) prostate cancer. It may reduce cancer activity while avoiding broader whole-body treatment for some patients.
LeuvenAges 18 years+ - NCT05357846RecruitingPhase 3
Check whether PD-1 treatment helps esophagus cancer before surgery
This Phase 3 trial tests whether adding a PD-1 medicine (sintilimab) to standard chemo-radiation before surgery improves outcomes for locally advanced esophageal squamous cell cancer. It may help by strengthening the immune response while shrinking the tumor before an operation.
Guangzhou, GuangdongAges 18–70 - NCT05377047Recruiting
Targeted radiation for limited recurrent breast cancer spread
This trial tests whether a precise form of high-dose radiation can control up to 1–5 breast cancer metastases (spread) in a few body areas. It may help by focusing treatment only on visible spots while limiting radiation to the rest of the body.
Gothenburg, Västra GötalandsregionenAges 18 years+ - NCT05378633Recruiting
CyberKnife treatment for multiple brain metastases
This trial looks at how well (and how much) CyberKnife radiation works for people with multiple brain metastases. It may help your care team understand the best way to treat several brain spots safely.
HeidelbergAges 18 years+ - NCT05387603RecruitingPhase 3
Targeted radiation for certain advanced neuroendocrine tumors
This Phase 3 study tests whether a targeted radiation treatment approach (using a special “PRRT” scan-guided method) works better to control advanced neuroendocrine tumors. It’s designed for tumors that show strong targeting on a specific PET scan and that are growing despite prior treatment (with some limits).
GothenburgAges 18 years+ - NCT05394428Recruiting
Study sexual side effects after pelvic radiation in women
This study looks at sexual side effects after pelvic radiation for certain cancers of the female reproductive organs. It may help improve how these problems are understood and managed after treatment.
Atlanta, GeorgiaAges 18 years+ - NCT05398094RecruitingPhase 2
Sotorasib for KRAS-mutant Stage III lung cancer without chemo-radiation
This Phase 2 study tests sotorasib (also called AMG510) in people with Stage III lung cancer that cannot be removed by surgery and that has a specific KRAS mutation (p.G12C). You may be able to join if you cannot safely receive chemo-radiotherapy at the same time, and the study checks whether sotorasib can help shrink or control the cancer.
Alicante, AlicanteAges 18 years+ - NCT05406063Recruiting
Focused radiation for bone metastases causing pain
This trial studies a precise type of radiation given in multiple small sessions to treat bone metastases that are causing pain. It may help shrink or control the spots in the bone while aiming to reduce side effects by targeting the area closely.
Winterthur, Canton of ZurichAges 18 years+ - NCT05444270Recruiting
Radiation and medicine for recurrent ovarian cancer
This trial studies a “salvage” (next-line) cancer treatment for recurrent epithelial ovarian cancer, with or without a focused type of radiation. It may help by shrinking or controlling limited spots of cancer that have come back after prior standard treatment.
SeoulAges 19 years+ - NCT05448547RecruitingPhase 3
Tested curative vs conservative treatment for older men with high-risk prostate cancer
This Phase 3 study compares an immediate curative treatment plan versus a more conservative approach in men age 75 and older with newly diagnosed, high-risk prostate cancer. The goal is to see which strategy controls the cancer while better protecting quality of life.
CopenhagenAges 75 years+ - NCT05468242RecruitingPhase 2
Tislelizumab after lung cancer chemotherapy and radiation
This Phase 2 study tests tislelizumab (an immune medicine) given after chemotherapy and radiation for stage III non-small cell lung cancer that has not been treated before. It may help improve how well the cancer responds and how long patients can stay in remission, with or without an added medication called bevacizumab.
GuangzhouAges 18–75 - NCT05477264RecruitingPhase 2
Tislelizumab with radiation for early nasal lymphoma
This trial tests whether adding a medicine called tislelizumab to radiation works better than radiation alone for newly diagnosed nasal (nasal-type) NK/T-cell lymphoma. If you qualify, it may help control the cancer and improve outcomes by using both treatments together.
SeoulAges 19 years+ - NCT05486650Recruiting
Study of focused radiation after PD-1 treatment helped non-lung cancer
This observational study looks at how stereotactic (high-precision) radiation works for advanced non-small cell lung cancer that is stable after PD-1 antibody treatment (sometimes with chemotherapy). It may help doctors better understand which patients benefit from this next treatment step and what side effects to expect.
Chongqing, Chongqing MunicipalityAges 18–75 - NCT05491395Recruiting
Radiation after mastectomy with breast implant reconstruction
This trial studies a radiation schedule given after breast cancer surgery when your breast was rebuilt right away with a prosthesis (implant or similar). It aims to see whether this “hypofractionated” (fewer, larger treatment sessions) radiation approach is appropriate for patients who need additional (adjuvant) radiation to reduce recurrence risk.
