Gilbert, ArizonaAges 30 years+ - 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+ - NCT02797717Recruiting
Treatment study for classical Hodgkin lymphoma in young people
This trial looks at a treatment approach for children and adolescents with classical Hodgkin lymphoma. It may help by testing how well the treatment controls the cancer and is tolerable in young patients.
Petah TikvaAges 1 month–18 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 - 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 - NCT02824731Recruiting
Proton vs photon radiation for certain brain tumors
This study compares two types of radiation—protons and photons (X-rays)—for specific brain tumors or tumor returns. It aims to see which approach works best and is safest for you, based on how much and where the radiation is delivered.
DresdenAges 18 years+ - NCT07742332RecruitingPhase 2
Targeted therapy before surgery for EGFR-mutant lung cancer
This trial tests a combination of two targeted medicines (befotertinib and bevacizumab) before surgery for people with EGFR-mutant non-small cell lung cancer that cannot be removed right away. The goal is to see if this treatment can shrink the tumor and improve surgery outcomes.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT02435576Recruiting
Standard follow-up program for head and neck cancer patients
This trial sets up a standard schedule for follow-up visits for people receiving curative (aimed at cure) or after-surgery radiotherapy for head and neck cancer. It may help you stay on track with regular check-ins and early management of side effects or signs of recurrence.
GroningenAges 18 years+ - NCT02354274Recruiting
New radiation approach for locally advanced lung cancer
This study tests a new way of giving radiation for people with locally advanced non-small cell lung cancer (NSCLC), along with a chemotherapy medicine (navelbine). It may help by improving how well the treatment controls the cancer in the chest while watching for side effects.
AalborgAges 18 years+ - NCT02290145RecruitingPhase 2
Study of Cyclin D1–targeted chemotherapy before oral cancer surgery
This Phase 2 trial tests a chemotherapy plan given first (before surgery) for people with oral squamous cell carcinoma that has specific cancer markers and lymph node involvement. It aims to shrink or control the cancer so treatment after may work better.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT02454790Recruiting
Follow-up program for people with esophageal cancer
This trial tests a standard follow-up plan for people who have esophageal cancer and received a certain amount of radiation. It may help your care team monitor side effects and catch health changes early.
GroningenAges 18 years+ - NCT02504788Recruiting
Protect the brain’s memory area during whole-brain radiation
This study tests whether avoiding the hippocampus (a part of the brain important for memory) during whole-brain radiotherapy can slow down thinking and memory decline. It may help some people preserve neurocognitive function while still treating brain metastases.
TaoyuanAges 18–84 - NCT02457962Recruiting
Registry study of outcomes from Mayo radiation treatments
This study collects information about how patients do after radiation treatment and stores some biological samples for future research. It includes people treated at Mayo Clinic Rochester for a cancer-focused (curative) course of radiation.
Rochester, MinnesotaAges Any age - NCT01766297RecruitingPhase 2
Proton radiation after lumpectomy for early breast cancer
This trial studies a type of radiation made with protons to treat only part of the breast after surgery (lumpectomy) for early-stage breast cancer. It may help control the cancer while aiming to reduce radiation to surrounding tissues.
Scottsdale, ArizonaAges 50 years+ - NCT07744074Recruiting
Carbon-ion radiation for large chest tumors
This trial tests a new type of radiation using carbon ions to treat large tumors in the chest that have come back or not responded to prior treatments. It aims to see if this therapy is safe and effective for people who have few options.
Hangzhou, ZhejiangAges 18 years+ - 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+ - NCT02016248Recruiting
Radiation “boost” for higher-risk prostate cancer
This trial studies whether adding a stronger “boost” dose of targeted radiation (SBRT) can better control higher-risk prostate cancer. It may help by increasing radiation coverage to the prostate while trying to limit treatment to surrounding areas.
Fountain Valley, CaliforniaAges 18 years+ - NCT01985984Recruiting
Predicting outcomes after head and neck radiotherapy
This study looks at how outcomes may be predicted for people with head and neck cancer who receive radiotherapy. It may help doctors better estimate results and tailor follow-up care.
MaastrichtAges 18 years+ - NCT01185132RecruitingPhase 3
IMRT versus partial-breast radiation after lumpectomy
This study compares two different ways of giving radiation to the breast after lumpectomy for early-stage breast cancer. It may help determine which approach controls the cancer well while reducing radiation to surrounding healthy tissue.
Aurora, ColoradoAges 40 years+ - NCT00026650Recruiting
Understanding Long-Term Effects After Radiation Therapy
This study follows patients who have received radiation therapy to learn about long-term health effects and how the disease progresses over time. By tracking your health over the years, researchers hope to better understand and help future patients manage side effects.
