Salvage treatment for breast cancer that returned locally
This trial looks at how well “salvage” treatments work for breast cancer that has come back only in the local area (like the chest wall or nearby lymph nodes), without spreading to distant organs. It also tracks side effects to better understand the risks and benefits for patients who need additional treatment.
SeoulAges 18–100 - NCT05939661RecruitingPhase 2
Total treatment before surgery for early rectal cancer
This Phase 2 study tests a “total neoadjuvant” approach, meaning you receive cancer treatment before surgery, to improve safety and effectiveness for rectal cancer. It may help by shrinking the tumor and planning a more effective operation, while researchers carefully track side effects.
OsakaAges 18 years+ - NCT05962242RecruitingPhase 2
HPV-tested de-escalated radiation for HPV-related throat cancer
This Phase 2 study uses HPV test results from your tumor to safely lower (de-intensify) the strength of radiation for some HPV-positive oropharyngeal throat cancers. It aims to reduce side effects while keeping cancer control effective.
Miami, FloridaAges 18 years+ - NCT05982691Recruiting
Asian data collection for CNS germ cell tumors
This trial is creating a consortium to collect data from Asian patients with CNS germ cell tumors. It helps researchers understand these tumors better and may lead to better treatments.
Goyang-si, Gyeonggi-doAges Any age - NCT05996432RecruitingEarly Phase 1
Using imaging to guide radiation therapy for head and neck cancer or brain tumors
This trial uses a special PET scan tracer called 18F-FMISO to see areas of low oxygen (hypoxia) in your tumor. The results may help doctors adjust your radiation plan to target those areas more precisely.
Nashville, TennesseeAges 18 years+ - NCT06016387RecruitingPhase 2
Drug combo with radiation for HER2+ breast cancer spread to spinal lining
This trial tests a combination of three targeted drugs (tucatinib, trastuzumab, and capecitabine) along with radiation to the brain or spine for people whose HER2-positive breast cancer has spread to the lining of the brain or spinal cord. The goal is to see if this treatment is safe and effective.
Ottawa, OntarioAges 18 years+ - NCT06026943Recruiting
Alpha radiation therapy for locally advanced pancreatic cancer
This trial tests a new treatment that uses tiny alpha radiation sources placed directly into the tumor to destroy cancer cells. It is for people with pancreatic cancer that has not spread but cannot be removed surgically, and who have already tried at least one type of chemotherapy or cannot take more chemo.
VeronaAges 18–120 - NCT06033183Recruiting
Study of radiation sensitivity in children with cancer
This study looks at how children's bodies respond to radiation therapy for certain cancers. By analyzing blood samples, researchers hope to learn why some children experience more side effects, which could help personalize future treatments.
CaenAges 3–18 - 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+ - NCT06036706Recruiting
Radiation types and thinking skills for skull base meningioma
