Recruiting studies
- NCT03617237Recruiting
Radiation patient registry for cancer and non-cancer cases
This study keeps records to understand outcomes for people who had radiation treatment (or were evaluated for it) since 2000. It may help doctors compare results for different conditions and treatment approaches, including cancer and non-cancer problems.
Dallas, TexasAges 18–99 - NCT03643861Recruiting
Radiation after lumpectomy for certain early breast cancers
This trial tests a short, highly targeted radiation plan given in five sessions after lumpectomy for early-stage breast cancer. It may help treat the remaining breast area while aiming to limit exposure to healthy tissue.
Birmingham, AlabamaAges 18–99 - NCT03671252RecruitingPhase 3
Chemotherapy before surgery for rectal cancer vs chemo with radiation
This Phase 3 trial compares two treatment plans given before rectal surgery. It tests whether stronger chemotherapy alone works better than chemotherapy pills plus long-term radiation to improve outcomes for locally advanced rectal cancer.
Guangzhou, GuangdongAges 18–75 - NCT03672721RecruitingPhase 1/Phase 2
Carboplatin with radiation for returning glioblastoma
This Phase 1/2 study tests a combination of carboplatin chemotherapy with radiation for glioblastoma that has come back. It aims to shrink or control the tumor after standard treatment has already been used.
Sherbrooke, QuebecAges 18 years+ - NCT03678025RecruitingPhase 3
Standard treatment for metastatic prostate cancer, with or without local treatment
This Phase 3 trial studies whether using the usual medicines for metastatic prostate cancer, plus a definitive local treatment to the prostate, improves outcomes. It may help determine if treating the prostate directly can benefit people whose cancer has not worsened after initial hormone-based treatment.
Gilbert, ArizonaAges 18 years+ - NCT03696680RecruitingPhase 2
Stereotactic radiation for brain metastases that recently bled
This trial tests a precise type of radiation aimed at brain metastases that show signs of recent bleeding. It aims to control the tumors while reducing risks, especially compared with the usual approach for patients who have bleeding signals in the brain lesions.
AvranchesAges 18 years+ - NCT03739411RecruitingPhase 1
MRI scan with a special agent to assess brain tumors
This Phase 1 study tests a new type of MRI scan using a special “hyperpolarized” imaging agent to help doctors diagnose glioma (a type of brain tumor). It’s mainly focused on whether the scan can safely and clearly show tumor-related information in people who may need treatment.
San Francisco, CaliforniaAges 19 years+ - NCT03802851Recruiting
Laser procedure before radiation for prostate cancer symptoms
This trial looks at whether doing a prostate “laser procedure” (called HoLEP) before starting radiation and hormone therapy can improve severe urinary symptoms and reduce urine retention problems. It is for people with prostate cancer who are planning radiation plus hormone treatment and who have significant bladder/urinary trouble.
Kansas City, KansasAges 18 years+ - NCT03804944RecruitingPhase 2
Vaccine trial for hormone-positive breast cancer
This Phase 2 study tests an individualized vaccine made from your tumor information to help your immune system fight hormone-positive breast cancer. You may be able to participate if you meet specific hormone-receptor, health, and treatment-timing requirements.
Los Angeles, CaliforniaAges 18–90 - NCT03810651RecruitingEarly Phase 1
Radiation planning for kidney tumors in children and teens
This early study tests a type of radiation delivery (“pencil beam scanning”) for certain kidney cancers in children and teens. It may help doctors better target the tumor while reducing radiation to nearby healthy tissue.
Philadelphia, PennsylvaniaAges birth–30 years - NCT03818503Recruiting
Study of European radiotherapy infrastructure for cancer care
This study looks at how radiotherapy (radiation treatment for cancer) is planned and delivered across participating centers in Europe. If you may need radiotherapy, this research may help improve how cancer radiation care is organized and provided.
GrazAges 12 years+ - NCT03836196Recruiting
Improve treatment for advanced prostate cancer with careful planning
This study looks at how to best plan and deliver treatment for men with advanced local prostate cancer. It may help find the most effective approach while keeping side effects manageable.
Vancouver, British ColumbiaAges 18 years+ - NCT03858205Recruiting
Low-dose radiation to relieve pain from bone tumors
This trial studies whether low-dose radiation can reduce pain from a specific bone lesion caused by multiple myeloma. It may help people whose main problem is painful bone metastasis, with targeted treatment to the painful spot.
Duarte, CaliforniaAges 18 years+ - NCT03908684Recruiting
Ultrasound tests to predict early response to prostate and head/neck radiation
This study uses special ultrasound imaging to look for early signs of how well radiation treatment is working in prostate, rectum, and head/neck cancers. It may help doctors spot response sooner and adjust care earlier if needed.
Toronto, OntarioAges Any age - NCT03936478RecruitingPhase 2
MRI-guided partial breast radiation in three short treatments
This study tests a faster, targeted type of radiation for early breast cancer, using real-time MRI to help plan and guide treatment. It may help deliver the same cancer-fighting effect while limiting radiation to the rest of the breast.
Madison, WisconsinAges 40 years+ - NCT03946202RecruitingPhase 2
Radiation plus an in-tumor drug for breast cancer
This Phase 2 trial tests adding a drug inside the tumor (an “in-tumor” injection) to make radiation work better for locally advanced or recurrent breast cancer. It’s meant to help control the tumor area for better long-term local symptom control.
Trivandrum, KeralaAges 18 years+ - NCT03961776Recruiting
MRI to monitor treatment response in rectal cancer
This trial tests whether an MRI scan done during chemoradiation can help doctors track how rectal cancer treatment is working. It may improve how they measure response early so treatment planning can be better tailored.
Los Angeles, CaliforniaAges 18 years+ - NCT03970447RecruitingPhase 2/Phase 3
Testing several treatment options for new or returning glioblastoma
This trial studies different treatment regimens for people with glioblastoma that is either newly diagnosed or has come back. It aims to find which treatment approach works best for controlling the tumor and improving outcomes.
Birmingham, AlabamaAges 18 years+ - NCT03975231RecruitingPhase 1
Targeted drugs and radiation for BRAF-mutated thyroid cancer
This Phase 1 trial studies whether targeted medicines (dabrafenib and trametinib) plus radiation can control an aggressive thyroid cancer with a specific BRAF gene change. It may help by attacking cancer cells that have this mutation and using focused radiation to improve tumor control.
Duarte, CaliforniaAges 18 years+ - NCT04004312Recruiting
Short-course radiation slices for localized prostate cancer
This trial tests a radiation approach that delivers treatment in a small number of larger “fractions” (short-course SBRT) for prostate cancer. It may help by targeting the prostate while shortening the overall number of visits.
Montreal, QuebecAges 18 years+ - NCT04340024Recruiting
Testing blood markers linked to how well radiation works
This study looks for “biomarkers,” or measurable signs (often from blood or samples), that may show which cancers respond better to radiation therapy. It may help doctors choose radiation treatment more precisely, especially for people who had significant side effects before.
SingaporeAges 21–99 - NCT06966388RecruitingPhase 1
Azelaic acid cream for breast cancer patients during radiation
This study tests whether using a topical azelaic acid cream twice daily during radiation therapy is feasible for breast cancer patients. The cream may help reduce skin side effects from radiation, and the study focuses on people with certain skin types that tan easily or have more pigment.
Richmond, VirginiaAges 18 years+ - NCT06205485RecruitingPhase 3
Chemotherapy and surgery vs chemoradiation for rectal cancer
This trial compares two approaches for early-stage rectal cancer: chemotherapy plus local surgery versus standard chemoradiotherapy. It aims to see if less intensive treatment can work just as well, reducing side effects.
Phoenix, ArizonaAges 18 years+ - NCT04033497Recruiting
MRI study to tell tumor from dead tissue after brain radiation
This study uses MRI scans to figure out whether an enlarging spot in the brain after stereotactic (focused) radiation is still living tumor or dead tissue. It may help doctors better understand what’s happening after radiation and guide next treatment decisions.
