New combo before surgery for low rectal cancer
This trial tests a new combination of treatments (radiation, immunotherapy, and two chemotherapy drugs) given before surgery for people with a specific type of locally advanced rectal cancer that is close to the anus. The goal is to see if this approach is safe and effective.
Shantou, GuangdongAges 18–75 - NCT02973828Recruiting
Daily MRI scans to guide cancer radiotherapy
This trial tests whether doing daily MRI scans during planned radiotherapy can help guide treatment. It may benefit people by improving how accurately the team sees the target area each day.
Sutton, SurreyAges 3 years+ - NCT02992574Recruiting
Radiation after mastectomy for certain node-negative breast cancers
This trial studies whether giving radiotherapy after a mastectomy helps prevent breast cancer coming back in women whose lymph nodes are not involved (or only very tiny spread). It may help reduce recurrence risk, especially for patients with higher-risk features despite node-negative early cancer.
Chandigarh, ChandigarhAges 18–80 - NCT02997709Recruiting
Collecting prostate cancer body marker samples during treatment
This study collects and measures “biomarkers” (measurable signs in the body) from people with prostate cancer who are about to have surgery or radiation. The goal is to understand how prostate cancer behaves during treatment, which may help improve care in the future.
Miami, FloridaAges 30 years+ - NCT03001362Recruiting
Wait-and-see treatment for people with rectal cancer
This study tests a “wait-and-see” approach instead of immediate surgery for certain rectal cancers, aiming to avoid unnecessary operations. It may help people who are medically able to stay under close monitoring and only have surgery if needed.
Montreal, QuebecAges 18–90 - NCT03079323RecruitingPhase 2
Radiation before or after surgery for prostate cancer spread to lymph nodes
This Phase 2 trial studies whether giving planned radiation to certain lymph node areas (para-aortic/“PART”) after surgery helps people whose prostate cancer has spread to lymph nodes (pN1). You would be screened after a specific lymph node surgery (ePLND) to see if you match their situation, then receive the trial’s radiation plan and follow-up.
LeuvenAges 18 years+ - NCT03144167Recruiting
Blood and scan markers to predict benefit from bevacizumab
This study looks for blood test markers that may predict who survives at 6 months after starting bevacizumab for glioblastoma that has come back. It does not aim to cure the cancer by itself, but to improve doctors’ ability to choose the most helpful treatment plan.
Amiens, PicardieAges 18 years+ - NCT03158090Recruiting
Study of treatment patterns for acromegaly over time
This study follows people with acromegaly to better understand how treatments are used in real life and how well they work over time. It may help improve future treatment choices by comparing outcomes across different care patterns.
Guangzhou, GuangdongAges 18–75 - NCT03353467Recruiting
Surgery through the nose for early nasopharyngeal cancer
This trial tests whether a minimally invasive surgery done through the nose can help people newly diagnosed with early-stage nasopharyngeal cancer. It looks for patients who have not had prior cancer treatment and who are healthy enough for the procedure and follow-up.
Guangzhou, GuangdongAges 18–70 - NCT03534713RecruitingPhase 3
Cervical cancer treatment plan after lymph node spread
This trial tests a specific chemotherapy start (induction) followed by standard treatment for cervical cancer that has spread to lymph nodes near the aorta. It may help improve cancer control compared with standard timing/approach.
BordeauxAges 18 years+ - NCT03534050RecruitingPhase 2/Phase 3
Testing new radiotherapy outcomes after low-grade brain tumor surgery
This trial studies how patients with grade 2 or 3 low-grade brain gliomas do after modern radiotherapy following surgery (or biopsy). It looks at both brain/memory functioning and cancer outcomes, especially for people at higher risk from their surgery or age.
TaoyuanAges 20–84 - NCT03587480Recruiting
Surgery methods after chemo-radiation for stage 3 rectal cancer
This trial compares two different surgery approaches after chemo-radiation for stage 3 rectal cancer. It aims to see which operation helps control the cancer more effectively while keeping surgery as safe as possible.
Guangzhou, GuangdongAges 18–75 - 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 - 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+ - 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+ - NCT03747133Recruiting
Radiation treatment for certain kidney tumors
This trial tests a focused, high-dose radiation treatment (SABR) for kidney tumors that are too risky to remove with surgery or where surgery was declined. It may help shrink the tumor while limiting damage to surrounding tissue.
Toronto, OntarioAges 18 years+ - NCT03788213Recruiting
Shorter vs longer radiation after breast cancer surgery
This trial compares giving breast radiation over one week versus three weeks after surgery. It aims to see whether the shorter schedule works just as well and is safe for people with certain types of early breast cancer.
Kolkata, West BengalAges 18 years+ - NCT03808337RecruitingPhase 2
SBRT radiation plus standard treatment for spread cancer
This trial looks at adding a focused radiation treatment called SBRT to standard care for cancers that have spread to a limited number of spots. It aims to control those spread-out tumors while still using the usual cancer treatment plan.
San Carlos, CaliforniaAges 18 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+ - NCT03829033Recruiting
Photon vs proton radiation for early tonsil cancer
This trial compares two types of radiation—photon therapy and proton therapy—for early-stage tonsil cancer. The goal is to see which approach works well for cure while affecting surrounding tissues differently.
