Edegem, AntwerpenAges 18 years+ - NCT06743789Recruiting
Radiation therapy for ventricular tachycardia: one or three sessions
This trial tests whether a single session of targeted radiation (radioablation) is as effective as three sessions for treating a dangerous heart rhythm called ventricular tachycardia in people with heart muscle disease. It's for those who continue to have episodes despite medication and catheter ablation.
New York, New YorkAges 18–90 - NCT06691776Recruiting
Adaptive radiotherapy for five cancer types
This trial tests whether a newer type of daily CT scan (CBCT-guided adaptive radiotherapy) can safely and accurately deliver radiation to cancers of the prostate, cervix, bladder, lung, or head and neck. The goal is to better target the tumor and reduce side effects.
AmsterdamAges 18 years+ - NCT05265208RecruitingPhase 2
Radiation plus chemo after liver surgery for bile duct cancer
This trial studies giving a special internal radiation treatment along with capecitabine (a chemotherapy) for liver cancer related to bile ducts, after planned surgical removal. It may help improve control of the cancer in cases where surgeons think the edges of the removed tumor may be too close.
Rennes, Brittany RegionAges 18 years+ - NCT05457595Recruiting
Re-irradiation for pelvic and groin cancer recurrences
This study tests giving radiation again to treat a cancer that has returned in the pelvic area (including the groin) when surgery isn’t a good option. It may help control the tumor while trying to protect nearby organs such as the small intestine.
Pavia, PvAges 18 years+ - NCT06250972RecruitingPhase 3
Radiotherapy for advanced pancreatic cancer with normal CA19-9 after chemo
This trial tests whether giving radiotherapy to the pancreas can help people with advanced pancreatic cancer whose CA19-9 level has dropped to normal after chemotherapy. It's for patients whose cancer is still locally advanced (hasn't spread to distant organs).
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06704659Recruiting
Repeated radiation for recurrent breast cancer
This study tests giving a second round of radiation therapy to women whose breast cancer has come back in the same breast, at least 3 years after their first radiation. It may be an option for women 55 and older who have a small, local recurrence that can be removed with surgery.
HelsinkiAges 55 years+ - NCT06702033RecruitingPhase 2
Surgery for HPV-related oropharyngeal cancer
This trial is testing a surgical approach for people with HPV-related oropharyngeal cancer that is stage I or II (but not the very smallest). The goal is to see if removing the tumor through the mouth and taking out neck lymph nodes is effective and safe. It may be an option if you are healthy enough for surgery.
St Louis, MissouriAges 18 years+ - NCT06220435Recruiting
Radiation therapy for very high-risk localized prostate cancer
This trial tests radiation therapy for men with very high-risk prostate cancer that hasn't spread. It aims to see if targeting the tumor with radiation can help control the cancer in this highest risk group.
LundAges 18 years+ - NCT06692556RecruitingPhase 3
Radiation vs monitoring for high-risk skin cancer
This trial compares two strategies after surgery for a type of skin cancer (cutaneous squamous cell carcinoma) that has a high chance of coming back. One strategy gives radiation therapy to the area, while the other just watches and checks for any signs of recurrence. The goal is to see if radiation can prevent the cancer from returning.
Le Puy-en-Velay, Auvergne-Rhône-AlpesAges 18 years+ - NCT06650579RecruitingPhase 3
Heart safety study of relugolix vs leuprolide for prostate cancer
This trial compares two hormone therapy combinations for men with prostate cancer that hasn't spread. The goal is to see if a newer oral medication (Relugolix) plus abiraterone works better than the standard injectable therapy (Lupron) plus abiraterone, while also checking heart safety.
Atlanta, GeorgiaAges 18 years+ - NCT06635980RecruitingPhase 2
Radiation before or after breast cancer surgery
This trial compares two ways of giving radiation for breast cancer that has not spread: before or after surgery. It aims to see if giving radiation first might work as well or better.
Scottsdale, ArizonaAges 18 years+ - NCT06623656RecruitingPhase 2
Pre-surgery treatment comparison for non-small cell lung cancer
This trial compares two treatment approaches before surgery for non-small cell lung cancer (NSCLC): radiation plus immunotherapy versus chemotherapy plus immunotherapy. The goal is to see which combination works better to shrink the tumor before it is removed.
New York, New YorkAges 18 years+ - NCT06586255RecruitingPhase 1
Immunotherapy and radiation after bladder cancer surgery
This trial tests whether adding radiation therapy to immunotherapy after bladder removal surgery can help prevent cancer from coming back. It's for people with advanced bladder cancer who have already started immunotherapy.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06574880RecruitingPhase 1/Phase 2
Radiation and Lutetium PSMA for locally advanced prostate cancer
This study tests a combination of focused radiation (SBRT) and a targeted radioactive drug (Lutetium PSMA) for men with prostate cancer that has spread to nearby lymph nodes or has high-risk features but has not yet reached distant organs. The goal is to see if this approach is safe and effective.
Cleveland, OhioAges 18 years+ - NCT06541158Recruiting
Help with transportation for cancer treatment
This study tests a tool to help patients with solid tumors who are getting radiation therapy overcome transportation problems. If you have trouble getting to appointments, this could help you find ways to get there more easily.
Atlanta, GeorgiaAges 18 years+ - NCT06547398Recruiting
