This study compares two types of radiation—protons versus photons—for anal canal squamous cell carcinoma. It may help find which option delivers treatment more effectively or with fewer side effects.
GothenburgAges 18 years+ - NCT04472845Recruiting
Shorter or longer breast radiation after surgery for high-risk cancer
This trial compares two schedules of radiation after breast surgery in people with high-risk, node-positive breast cancer. The goal is to see whether giving radiation in 1 week or 2 weeks works well and is safe after standard treatments.
ChandigarhAges 18 years+ - NCT04474964Recruiting
Radiotherapy plus chemo for WNT medulloblastoma in children
This study tests whether adding a specific brain/spinal radiation plan (focused radiation plus low-dose spinal coverage) followed by chemotherapy works well for children with newly diagnosed WNT medulloblastoma after surgery. It targets kids whose remaining tumor after surgery is small and who have no spread to the spine or fluid.
Mumbai, MaharashtraAges 3–16 - NCT04481763RecruitingPhase 1/Phase 2
Camrelizumab plus radiation for early triple-negative breast cancer
This trial studies whether adding camrelizumab (an immunotherapy drug) to radiation can improve outcomes and be safe for people with early triple-negative breast cancer. It is designed for specific early-stage cases after breast surgery, using tumor and blood tests to match the cancer’s features.
Nanchang, JiangxiAges 18–75 - NCT04498767Recruiting
Radiation to treat a few metastatic spots in rare cancers
This trial studies whether stereotactic (high-precision) radiation given in a few sessions can control rare cancers that have spread to a small number of sites. It aims to help by treating all known spots while keeping side effects manageable.
AnderlechtAges 18 years+ - NCT04519905Recruiting
Testing two ways of radiation in older esophagus cancer patients
This study compares a planned radiation approach given at the same time as other treatment for older adults with esophageal squamous cell carcinoma. It may help find a safer and more effective radiation schedule for people who are fit enough for treatment.
Nanjing, JiangsuAges 76 years+ - NCT04550104RecruitingPhase 1
Durvalumab with radiation for lung cancer patients
This trial tests adding durvalumab (an immune therapy) to a radiation treatment plan for people with non-small cell lung cancer (NSCLC) who can’t safely have chemotherapy at the same time or surgery first. It aims to improve cancer control after radiation by helping the immune system recognize and fight the tumor.
BelfastAges 18 years+ - NCT04570943RecruitingPhase 2
Pancreatic cancer treatment: chemo first, then targeted MRI-guided radiation
This Phase 2 trial tests giving specific chemotherapy in sequence, then using MRI-guided focused radiation to treat locally advanced, non-removable pancreatic cancer. It may help shrink or control the tumor while aiming radiation more precisely using MRI.
Marseille, Bouches-du-RhôneAges 18–75 - NCT04612907Recruiting
Radiation timing options for low-burden metastatic prostate cancer
This study compares different radiation schedules to the main prostate tumor in men with low-burden metastatic (spread) hormone-sensitive prostate cancer. It may help find a radiation timing approach that controls the cancer while balancing side effects.
UmeåAges 18 years+ - NCT04702581RecruitingPhase 3
Delayed radiation versus usual timing for certain brain tumors
This trial studies whether delaying radiation therapy helps people with a slow-growing brain tumor called low-grade oligodendroglioma that has specific genetic markers. It compares delayed radiation to standard timing to see which approach controls the tumor with acceptable side effects and quality of life.
AmiensAges 18 years+ - NCT04722263Recruiting
Radiation treatment for raised scar tissue (keloids)
This study tests how radiation (RT) can treat keloids, especially when surgery is not possible or you choose not to do surgery. The goal is to see if radiation can safely improve or control the keloid.
The Bronx, New YorkAges 18 years+ - NCT04830267RecruitingPhase 2
