Gliwice, GliwicwAges 18–80 - NCT04688528Recruiting
Radiation planning to spare the opposite neck in head cancer
This trial tests a safer radiation plan that may reduce dose to the opposite (other) side of the neck while still treating the cancer spread risk. It uses special mapping to guide treatment and looks at patients whose cancer is already in an involved lymph node on one side.
Genk, LimburgAges 18 years+ - NCT07823855Recruiting
Faster radiation scheduling for aggressive non-small cell lung cancer
This trial studies a new way of giving radiation therapy to the chest for lung cancer that is growing quickly. The approach uses a special schedule to damage the cancer more effectively, which might improve how well the treatment works.
Hangzhou, ZhejiangAges 18 years+ - NCT05352178RecruitingPhase 3
Targeted treatment for few-spread prostate cancer spots
This Phase 3 trial tests whether treating only a small number of prostate cancer metastases can help people with “oligorecurrent” (limited repeat) prostate cancer. It may reduce cancer activity while avoiding broader whole-body treatment for some patients.
LeuvenAges 18 years+ - NCT07809776Recruiting
Tai chi for tiredness during radiation for head and neck cancer
This study tests whether practicing tai chi during radiation therapy helps reduce cancer-related tiredness (fatigue) in people with head and neck cancer. If you are undergoing radiation and feel tired, this gentle exercise may help you feel better.
Chengdu, SichuanAges 18–80 - NCT07815834RecruitingPhase 3
FAPI-guided radiation with cadonilimab and chemo for colorectal cancer spread to the abdomen
This trial tests a new combination treatment for colorectal cancer that has spread only to the lining of the abdomen (peritoneum). It combines targeted radiation, an immunotherapy drug called cadonilimab, and standard chemotherapy to see if it can help control the disease better than current options.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06086457RecruitingPhase 3
Immunotherapy plus chemo with or without radiation for esophageal cancer
This trial tests whether adding radiation therapy to a standard treatment (immunotherapy plus chemotherapy) can help people with advanced esophageal cancer that has spread to up to two organs. The goal is to see if the combination improves outcomes.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07801664RecruitingPhase 2
Short course hormone therapy for prostate cancer
This trial tests a short course of hormone therapy (androgen deprivation therapy) for men with a certain type of prostate cancer that is considered high-risk. The goal is to see if a shorter treatment period can still control the cancer while reducing side effects.
New York, New YorkAges 18 years+ - NCT07802002Recruiting
Dietary supplement to prevent bowel injury during radiation for rectal cancer
This trial tests whether a special dietary supplement can help protect the rectum from radiation damage during chemoradiation for locally advanced rectal cancer. If it works, it may reduce painful bowel symptoms like frequent stools and cramping.
Guangzhou, GuangdongAges 18–75 - NCT07808853RecruitingPhase 2
Short radiation plus chemo-immunotherapy before esophageal cancer surgery
This trial tests a new approach before surgery: a short course of radiation (5 treatments) combined with chemotherapy and immunotherapy. The goal is to shrink the tumor and increase the chance of successful removal, while hopefully reducing side effects and improving long-term outcomes.
Guanzhou, GuangdongAges 18–75 - NCT06507683Recruiting
Radiation plus ripretinib for advanced GIST
This trial tests whether adding radiation therapy to the drug ripretinib can help people with advanced gastrointestinal stromal tumors (GIST) that can't be removed by surgery and have stopped responding to other treatments. It aims to see if this combination is safe and effective.
