Recruiting studies
- NCT01621594Recruiting
Testing new radiation methods for heart CT images
This trial studies newer ways to take heart and blood vessel CT scans while using radiation more carefully. It may help improve image quality for people needing coronary CT angiography.
Bethesda, MarylandAges 18–100 - NCT01084785Recruiting
Banking blood samples from people with cancer
This study collects and stores blood and protein samples from people with cancer to help future research. You may be asked to return for follow-up appointments so the researchers can link your samples to health outcomes.
Maastricht, LimburgAges 18 years+ - NCT01834001Recruiting
MRI checks how prostate cancer responds to radiation
This study uses MRI scans to see how prostate cancer changes after radiation treatment, especially in the local (prostate-area) response. It may help doctors better judge treatment effectiveness and plan care more precisely.
Bethesda, MarylandAges 18–120 - NCT00083512Recruiting
Blood and Urine Collection in Glioblastoma Radiation Therapy
This study collects blood and urine samples from patients receiving radiation treatment for glioblastoma (a serious brain tumor) to help researchers understand how the body responds to radiation therapy. Participating is straightforward—you provide samples during your regular treatment.
Bethesda, MarylandAges 18–120 - NCT01803542RecruitingPhase 2
Stereotactic radiation for lung metastases or early lung tumors
This trial studies a precise, high-dose radiation technique (SBRT) to treat tumors in the lungs. It may help control cancer in people who either have early-stage lung cancer that is not fully operable or have limited lung metastases from other cancers.
Toronto, OntarioAges 18 years+ - NCT01255748Recruiting
Registry study tracking outcomes after radiation treatment
This registry study collects information from people who are planning to receive radiation therapy. The goal is to better understand treatment outcomes and help improve radiation care over time.
Scottsdale, ArizonaAges Any age - NCT01577251Recruiting
Cancer patients on radiation can join a registry
This study builds a registry and blood/tissue sample collection for people who have cancer or a non-cancer growth (benign tumor) and are receiving radiation. It helps researchers learn from real-world treatment and biology, which may improve future care.
Moorestown, New JerseyAges 18 years+ - NCT01284153Recruiting
Testing breast cancer radiation plans in a prone position
This study compares how well radiation treatment plans can be made when you lie face-down (prone) for breast cancer. It’s a planning study, meaning the main goal is to improve treatment planning and potential safety/comfort.
LeuvenAges Any age - NCT01542879RecruitingPhase 1/Phase 2
MR scan for cancer staging without radiation in children and adults
This study tests a radiation-free whole-body MRI method to help doctors stage (find and measure) certain cancers. It may reduce radiation exposure compared with scans that use X-rays or radioactive tracers, while still checking how far cancer has spread.
Stanford, CaliforniaAges 6–40 - NCT01649830RecruitingPhase 3
Temozolomide after radiation for low-grade brain tumor
This trial tests whether adding temozolomide chemotherapy after radiation helps control a type of low-grade brain tumor that was not fully removed. It may help reduce the chance the tumor comes back, compared with standard post-radiation care.
Guangzhou, GuangdongAges 18–60 - NCT01684904Recruiting
Proton beam radiation for certain esophagus cancers
This trial studies whether proton therapy can better treat early-to-mid stage esophagus cancer while aiming to reduce side effects to nearby organs. Proton therapy uses a targeted type of radiation, and participants are also checked to be eligible for curative surgery.
Loma Linda, CaliforniaAges 18 years+ - NCT02305654RecruitingPhase 3
Trial for penile squamous cancer with swollen groin or pelvis nodes
This Phase 3 study tests treatment options for penile squamous cell cancer that has spread to nearby groin and/or pelvic lymph nodes (but not to distant organs). If you have the right stage and haven’t had certain prior treatments, this trial may offer a structured treatment plan and close monitoring.
Los Angeles, CaliforniaAges 18 years+ - NCT02297217RecruitingPhase 2
Chemoradiation for advanced esophagus cancer that can’t be cured
This trial studies whether a combination of chemotherapy and radiation can help people with advanced esophageal cancer who cannot have curative treatment. It focuses on people who are having swallowing trouble and may be able to start treatment soon.
Calgary, AlbertaAges 18 years+ - NCT02634645Recruiting
Treatment study for Barrett’s pre-cancer or esophageal cancer
This study looks at treatment options for people with Barrett’s esophagus that has progressed to abnormal cell growth (dysplasia) or cancer. It may help doctors compare approaches that use procedures to remove and/or destroy abnormal tissue in the esophagus.
Los Angeles, CaliforniaAges 18–100 - NCT02185443RecruitingPhase 2
SBRT radiation for liver metastases that can’t be surgically removed
This trial studies stereotactic body radiation therapy (high-precision radiation given in a few sessions) for liver metastases when surgery isn’t possible. It may help shrink or control tumors in the liver and delay progression in people whose cancer has not spread outside the liver (or only to areas treated with a curative plan).
São Paulo, São PauloAges 18 years+ - NCT02468024RecruitingPhase 3
Surgery or focused radiation for early lung cancer
This study compares two treatments—removing only part of the lung (sublobar resection) versus a focused radiation approach (stereotactic ablative radiotherapy)—for early-stage non-small cell lung cancer. It aims to see which option works better with fewer problems for the right patients.
La Jolla, CaliforniaAges 18 years+ - NCT02573636Recruiting
Testing genes in prostate cancer after radiation relapse
This study looks at specific gene changes (TMPRSS2-ERG fusion and PTEN deletion) in people whose prostate cancer returned after radiation. It aims to understand who may have a higher risk of relapse and help predict outcomes after salvage or radical radiation.
Chicoutimi, QuebecAges 18 years+ - NCT02977468RecruitingPhase 1
Pembrolizumab for early triple-negative breast cancer tumor changes
This Phase 1 study tests pembrolizumab (an immune medicine) to see how it affects the tumor and its surroundings in triple-negative breast cancer. It’s mainly looking at safety and early signs of benefit, especially in a limited, early-stage breast tumor.
Atlanta, GeorgiaAges 21–80 - NCT02986516Recruiting
Surgery or definitive radiation for primary sacral chordoma
This trial compares two standard treatment approaches—surgery versus definitive radiation—for people with a primary sacral chordoma (a bone tumor at the lower spine/pelvis area). It aims to find which approach works best for controlling the tumor while considering treatment side effects.
GrazAges 18–80 - NCT03184038Recruiting
Testing brain function in people with brain metastases after radiosurgery
This study looks at how well your thinking and memory work after treatment with radiosurgery for brain metastases. It may help researchers understand which patients benefit best and how to monitor side effects on brain function.
Sewell, New JerseyAges 18 years+ - NCT03034187Recruiting
Track side effects after prostate cancer radiation
This study follows people with prostate cancer who receive radiation to understand what side effects and quality-of-life changes happen over time. It may help improve standard follow-up care by better tracking radiation-related toxicity.
GroningenAges 18 years+ - NCT03215719RecruitingPhase 2
De-escalating treatment for HPV-positive throat cancer with low-risk signals
This Phase 2 trial tests whether people with HPV-positive oropharyngeal (throat) cancer who look “lower risk” can safely receive less intensive treatment. It uses HPV blood test results and cancer staging scans to guide whether treatment can be de-escalated.
New York, New YorkAges 18 years+ - NCT06794086RecruitingPhase 3
SBRT and immunotherapy for colorectal cancer liver metastases
This trial combines targeted radiation (SBRT) with an immunotherapy drug (PD-1 inhibitor) to treat colorectal cancer that has spread to the liver and can't be removed by surgery. It aims to help shrink or control tumors in patients whose cancer has a normal DNA repair system (pMMR/MSS).
Guangzhou, GuangdongAges 18–75 - NCT07675967Recruiting
Blood Cell Changes During Cancer Treatment
This study is for people with solid tumors who are about to start chemotherapy or radiation. It looks at how these treatments affect blood cells and may help doctors understand changes in blood health over time.
