SeoulAges 18 years+ - NCT04927897Recruiting
Testing where to aim extra rectal radiation before surgery
This trial tests the best place to target an “extra boost” of radiation inside the rectum for certain rectal cancer patients. It may help guide more precise treatment planning before they have total mesorectal excision (TME) surgery.
Maastricht, LimburgAges 18 years+ - NCT07616297Recruiting
Higher Radiation Dose to Avoid Surgery in Rectal Cancer
This study tests whether giving a higher dose of radiation to rectal cancer tumors can help patients avoid surgery altogether. The goal is to shrink the tumor enough that surgery is no longer needed, preserving normal bowel function.
Rotterdam, South HollandAges 18 years+ - NCT04648462Recruiting
Proton therapy planning for certain brain tumors
This study builds and tests how proton therapy planning could better protect the brain compared with standard radiation (photon therapy) for adults with certain brain tumors. It may help reduce radiation to sensitive areas like the hippocampus, with the goal of better long-term brain function.
Maastricht, LimburgAges 18 years+ - NCT06240559Recruiting
Brachytherapy treatment verification study
This study checks if doctors can better verify brachytherapy (a type of internal radiation) during treatment for gynecological or prostate cancer. It may help improve accuracy and outcomes for patients receiving this therapy.
Maastricht, LimburgAges Any age - NCT03734952Recruiting
Radiation after esophagus surgery for stage II–III cancer
This study looks at whether giving radiation after surgery (after chemo and radiation before surgery) can improve outcomes for people with squamous cell esophagus cancer in the chest. You may be considered if you are well enough for treatment and your cancer has not spread.
Fuzhou, FujianAges 18–65 - NCT03466424Recruiting
Short radiation then chemotherapy for locally advanced rectal cancer
This trial tests a short course of radiation given before chemotherapy for people with locally advanced rectal cancer (cancer that has grown into nearby tissue and/or nearby lymph nodes but can still be removed). It may help shrink the tumor and make treatment more effective while assessing how well this approach works.
Fuzhou, FujianAges 18–70 - NCT04083937Recruiting
Radiation after prostate surgery for men with prostate cancer
This study looks at different radiation approaches after prostate surgery to see which strategy works best. You may be able to join if your cancer is at a stage where radiation to the prostate bed is planned, and you have not had prior radiation.
HeidelbergAges 18 years+ - NCT04865315Recruiting
Donate tumor samples to build organoid tissue from glioma
This study collects tumor tissue during brain surgery to create lab-grown “organoids” (mini models of the tumor). It aims to build a tissue bank that researchers can use to better study gliomas and develop treatments.
Maastricht, LimburgAges 18 years+ - NCT05224297Recruiting
Help us improve radiation care by sharing your experiences
This study collects patient-reported experiences and side effects from people getting external beam radiation (radiation treatment from outside the body). Your answers can help doctors improve how radiation care is delivered and supported.
Vienna, State of ViennaAges 18–100 - NCT05317221Recruiting
Developing breast cancer tissue models for research
This trial builds lab “models” (called organoids) from breast cancer tissue to help researchers study different breast cancer types. You may be able to help by providing consent and meeting the study’s basic cancer and treatment history requirements.
MaastrichtAges 18 years+ - NCT06036394Recruiting
AI for brain and spine radiation planning study
This study uses artificial intelligence to review radiation plans for patients with brain or spine tumors treated at Tata Memorial Centre between 2010 and 2022. It may help improve how radiation therapy is planned in the future.
Mumbai, MaharashtraAges 1 year+ - NCT06087614RecruitingPhase 2
Higher-dose radiation for head and neck cancer
This trial tests a higher dose of radiation therapy that is adjusted based on oxygen levels in the tumor. It may help people with certain head and neck cancers that have not been treated before.
DelhiAges 18–70 - NCT06531681Recruiting
Precision radiotherapy with MRI-guided technology
This trial tests a new type of radiotherapy that uses MRI scans to guide the radiation beam more precisely. It aims to treat tumors while reducing damage to healthy tissue.
HaikouAges 18–75 - NCT07004582Recruiting
Lab study using mini-tumors to test prostate cancer treatments
This trial uses leftover tumor tissue from biopsies or brachytherapy to grow mini-tumors in the lab. Researchers want to test different treatments on these mini-tumors to find the best options for patients with high-risk or recurrent prostate cancer.
Heerlen, LimburgAges 18 years+ - NCT07084519RecruitingPhase 3
Short vs standard radiation after mastectomy with implant reconstruction
This trial compares standard radiation therapy to a shorter course (hypofractionated) for women who have had a mastectomy with implant reconstruction. The goal is to see if the shorter schedule works as well while possibly reducing side effects for the reconstructed breast.
Beijing, ProvinceAges 18–75 - NCT01084785Recruiting
Banking blood samples from people with cancer
This study collects and stores blood and protein samples from people with cancer to help future research. You may be asked to return for follow-up appointments so the researchers can link your samples to health outcomes.
Maastricht, LimburgAges 18 years+ - NCT01577251Recruiting
Cancer patients on radiation can join a registry
