Radiation, chemotherapy, and immunotherapy for advanced rectal cancer
This trial tests a combination of radiation therapy, a chemotherapy drug called NALIRIFOX, and an immunotherapy drug called adebrelimab for rectal cancer that has grown into nearby tissue or lymph nodes. The goal is to see if this combination helps shrink the tumor before surgery and improves outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07628738RecruitingPhase 2
Lower-dose radiation for early-stage NK/T-cell lymphoma after chemotherapy
This study tests whether patients with a specific type of blood cancer (NK/T-cell lymphoma) in the nose or sinuses who have responded well to chemotherapy can be safely treated with reduced radiation doses instead of standard high-dose radiation. The goal is to reduce side effects while maintaining effective treatment.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05440149RecruitingPhase 3
Radiation after surgery for certain node-positive breast cancer
This study tests whether giving radiation after breast surgery can improve outcomes for people with breast cancer that has spread to nearby lymph nodes (N1). You may be a candidate if you’ve already had surgery and meet specific details about your lymph nodes and cancer type.
Seoul, Jongro-guAges 19 years+ - NCT07603856RecruitingPhase 2
Combining Immunotherapy and Radiation for Advanced Lung Cancer
This study tests whether adding focused radiation therapy to immunotherapy can help patients with advanced non-small cell lung cancer whose cancer has progressed despite prior immunotherapy. The goal is to see if this combination works better than immunotherapy alone.
Chicago, IllinoisAges 18 years+ - NCT07600268RecruitingPhase 2
Radiation plus maintenance drugs for advanced pancreatic cancer
This trial tests whether adding a focused radiation treatment (SBRT) to ongoing chemotherapy drugs works better than the drugs alone for pancreatic cancer that has stabilized or shrunk after initial treatment. The goal is to see if this combination approach helps patients live longer.
Jinan, ShandongAges 18–70 - NCT07594925RecruitingPhase 2
Short-course radiation plus immunotherapy and chemotherapy for rectal cancer
This trial tests a combination of brief radiation therapy followed by immunotherapy and chemotherapy for locally advanced rectal cancer that hasn't spread. The goal is to see if this approach helps patients avoid or reduce surgery while controlling their cancer.
TianjinAges 18–75 - NCT07585929Recruiting
Radiation Boost Techniques for Advanced Cervical Cancer
