This study tests a very short course of radiation given after prostate surgery, specifically for men whose PSA is rising again. The goal is to see if this approach can safely control the cancer.
Monza, ItalyAges 18–90 - NCT06942416RecruitingPhase 2
Study of iparomlimab and tuvonralimab with chemoradiation for recurrent cervical cancer
This trial tests whether adding two immunotherapy drugs (iparomlimab and tuvonralimab) to standard chemoradiation can help people with cervical cancer that has returned or spread to a few new places. The goal is to see if this combination improves outcomes for those whose cancer is no longer responding to initial treatment.
Jinan, Shandong RecruitingAges 18–75 - NCT06949098RecruitingPhase 2
Local tumor removal plus chemo-radiation for early low rectal cancer
This trial tests whether removing just the tumor locally, followed by chemotherapy and radiation, is effective for early-stage (T1-2 N0) rectal cancers located low or very low in the rectum. It may help you keep your anal opening and avoid major surgery that requires a permanent colostomy bag.
Shijiazhuang, HebeiAges 18–75 - NCT06953245Recruiting
Study of skin reactions from radiation in breast cancer patients
This study asks breast cancer patients about their skin reactions during radiation therapy. By sharing your experience, you can help doctors better understand and manage these side effects.
Rochester, MinnesotaAges 18 years+ - NCT06960707RecruitingPhase 3
One vs two weeks of breast radiation after lumpectomy
This trial compares a shorter, one-week course of radiation to the standard two-week course after a lumpectomy for early-stage breast cancer. The goal is to see if one week is just as effective and safe, making treatment more convenient.
New York, New YorkAges Any age - NCT06961955RecruitingPhase 2
Shorter versus longer whole breast radiation for early-stage breast cancer
This trial compares a 5-day course of whole breast radiation plus a boost to the standard 9-day course for people with early-stage breast cancer who have certain risk factors, such as high-grade tumors or younger age. The goal is to see if the shorter treatment is just as safe and effective.
Salt Lake City, UtahAges 18 years+ - NCT06962072Recruiting
Outcomes after limb-sparing surgery for soft tissue sarcoma
This study looks at how well patients do after surgery to remove a soft tissue sarcoma from an arm or leg while saving the limb. It helps doctors understand recovery and function after this type of surgery.
AmsterdamAges 18 years+ - NCT06968520Recruiting
Metals and Mouth Sores in Head and Neck Radiation
This study is looking at how certain metals in the body might relate to mouth sores caused by radiation therapy. Researchers at Nanfang Hospital want to find out if these metals can help predict who will get mouth sores, so doctors can better prevent or treat them.
Guangzhou, GuangdongAges 18–75 - NCT06971211RecruitingPhase 2
Radiation and drug combo for advanced prostate cancer
This trial combines radiation therapy with two drugs (fluzopanib and abiraterone acetate) to treat men with metastatic castration-resistant prostate cancer that hasn't been treated yet. The goal is to see if this triple approach helps slow the cancer's growth.
Shenyang, LiaoningAges 18 years+ - NCT06982469Recruiting
High-dose radiation for prostate cancer return after surgery
This trial tests a high-dose radiation treatment (brachytherapy) that places tiny radioactive seeds directly into the area where your prostate was. It is for men whose prostate cancer has returned only in that area after having their prostate removed.
Pamplona, Foral Community of NavarreAges 18–80 - NCT06984250Recruiting
Shorter radiation with extra focus on tumor site for breast cancer
This trial tests a shorter course of radiation therapy that includes an extra dose to the tumor site for women with early-stage breast cancer. It aims to make treatment more convenient and effective after breast-conserving surgery.
Taipei, TaiwanAges 20–85 - NCT06988956RecruitingPhase 2
Nimotuzumab Plus Chemoradiation for Older Adults with Esophageal Cancer
This trial tests adding nimotuzumab, a targeted therapy, to standard chemoradiation for elderly patients with esophageal squamous cell cancer. It aims to see if the combination improves outcomes.
NanjingAges 75 years+ - NCT06990542RecruitingPhase 2
Focused radiation therapy for intermediate and high-risk prostate cancer
This trial tests a more precise radiation therapy that targets tumors seen on MRI or special scans, aiming to treat prostate cancer while reducing side effects. It is for men who have not had prostate surgery or previous radiation to the area.
La Jolla, CaliforniaAges 18 years+ - NCT06992232RecruitingPhase 2
Radiation or surgery plus hormone therapy for prostate cancer that has spread
This trial tests whether giving intense hormone therapy along with either radiation or surgery can help men with prostate cancer that has spread to a limited number of spots (10 or fewer) but not to organs like the liver or lungs. The goal is to treat both the main tumor and the visible metastatic spots more aggressively.
Nanjing, JiangsuAges 18–80 - NCT06995664Recruiting
Higher radiation dose for kidney cancer that has spread
This trial tests whether giving a higher radiation dose to some tumors can help control kidney cancer that has spread to other parts of the body. It is for people who cannot have surgery to remove these tumors and are already receiving other treatments.
LondonAges 18 years+ - NCT06999785Recruiting
Oxygen therapy safety study for radiation treatment side effects
