Surgery types and radiation for spinal tumors that have spread
This study compares two types of spinal surgery combined with radiation for people whose cancer has spread to the spine in a limited way (no more than 5 spots). It aims to find which approach better controls pain, tumor growth, and spinal stability.
Shanghai, Shanghai MunicipalityAges 18–75 - 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+ - NCT04902937Recruiting
Testing how added radiation may work by immune and tumor markers
This study looks at people with non-metastatic invasive breast cancer who are getting curative breast surgery followed by planned radiation (sometimes with other anti-cancer medicines). Researchers want to understand whether a patient’s age and certain immune/tumor blood features can predict how well radiation helps.
JenaAges 18 years+ - NCT05424159Recruiting
Carbon ion radiation for locally advanced pancreatic cancer
This trial tests a type of radiation that uses carbon ions to treat pancreatic cancer that can’t be removed with surgery but has not spread to distant organs. It may help shrink or control the tumor while limiting radiation side effects to nearby organs.
ShanghaiAges 18–80 - NCT07866313RecruitingPhase 2/Phase 3
Chemotherapy, radiation, and immunotherapy before surgery for low rectal cancer
This trial tests a new combination of chemotherapy, radiation, and immunotherapy given before surgery for low rectal cancer. It aims to see if this approach can shrink tumors and improve outcomes for patients with a specific type of cancer that is microsatellite stable (MSS).
Shanghai, Shanghai MunicipalityAges 18–75 - NCT07865793RecruitingPhase 2
Lattice radiation with immunotherapy for advanced tumors
This trial tests a new way to give radiation called lattice therapy together with immunotherapy drugs that help your immune system fight cancer. It is for people with advanced solid tumors that have grown or spread, with at least one large tumor that can be measured.
Shenzhen, GuangdongAges 18–70 - NCT06220552RecruitingPhase 2
Low-dose radiation plus immunotherapy for recurrent glioblastoma
