GroningenAges 18 years+ - NCT07071103RecruitingPhase 2
Low-dose radiation and immunotherapy for resistant solid tumors
This trial tests a combination of low-dose radiation to the intestines and immunotherapy for people whose cancer has stopped responding to standard treatments including immunotherapy. It may offer a new option when other therapies have failed.
Shantou, GuangdongAges 18–80 - NCT07116213Recruiting
Shorter radiation after surgery for high-risk endometrial cancer
This trial studies a new type of radiation therapy (called online adaptive radiotherapy) given in shorter, higher daily doses after surgery for high-risk endometrial cancer. The goal is to see if this approach is safe and effective for reducing side effects while still controlling the cancer.
Beijing, Beijing MunicipalityAges 18–70 - NCT07139990RecruitingPhase 1
Personalized radiotherapy for lung cancer or brain tumors
This trial tests whether giving tailored radiation alongside standard treatments can improve outcomes for people with extensive stage small cell lung cancer or solid tumors that have spread to the brain. It aims to personalize your treatment plan based on your specific situation.
Dallas, TexasAges 18 years+ - NCT07165847RecruitingPhase 2
Combination therapy before surgery for gastric cancer
This trial tests a combination of radiation, chemotherapy, and two immunotherapy drugs before surgery for people with resectable gastric or gastroesophageal junction cancer. The goal is to see if this approach can shrink the tumor and improve outcomes.
