Guangzhou, GuangdongAges 18–80 - NCT04654338RecruitingPhase 2/Phase 3
Two types of targeted radiation for favorable prostate cancer
This trial tests whether two “ablative” (high-dose, focused) radiation treatments can work well for men with favorable-risk prostate cancer. It looks at whether the treatments are practical and safe, especially for urinary side effects.
Toronto, OntarioAges Any age - NCT04654364Recruiting
Lung cancer registry that tracks patient information
This trial is a registry that collects information from people with certain types and stages of lung cancer. It helps researchers understand how these cancers are managed in real life, which can guide better future care.
Salzburg, State of SalzburgAges 18 years+ - NCT04654975Recruiting
Metastatic brain tumors after esophagus surgery study
This study looks at people who had esophageal cancer surgery and later developed brain metastases. It may help doctors better understand who benefits from treatment planning after the original cancer surgery.
Houston, TexasAges Any age - NCT04657042Recruiting
4D MRI scans to guide lung or liver cancer radiation
This trial tests whether special “4D” MRI scans can improve precision radiation planning for people with lung or liver cancer. You may get MRI scan data to better account for tumor movement, alongside your usual radiation treatment.
Charlottesville, VirginiaAges 18–82 - NCT04659343Recruiting
Testing tumor care planning for metastatic kidney cancer
This trial studies a way to plan and manage care for people with metastatic renal cell carcinoma (kidney cancer that has spread). It may help doctors coordinate treatment more effectively to improve outcomes.
Aarhus, DanmarkAges 18 years+ - NCT04665687Recruiting
Genetic testing study for early stomach cancer and stomach polyps
This study uses genetic sequencing to learn more about early stomach cancer and precancerous stomach polyps. It may help improve how these conditions are understood and potentially guide future care, using genetic information from stored tissue samples.
SeoulAges 19–100 - NCT04665947RecruitingEarly Phase 1
Imaging and targeted drug for pancreatic cancer using special radiation
This early study tests a two-step approach: a special PET/CT scan to find pancreatic cancer, followed by a targeted radiation medicine to attack it. It may help researchers learn whether this targeted approach is safe and able to reach pancreatic tumors after standard treatment.
Sacramento, CaliforniaAges 18 years+ - NCT04669873Recruiting
Partial breast radiation vs whole breast radiation after lumpectomy
This trial studies whether treating only part of the breast with radiation works as well as treating the whole breast in people with early breast cancer after lumpectomy. It may help reduce radiation exposure to healthy tissue, while still controlling the cancer.
São Paulo, São PauloAges 50–90 - NCT04671940Recruiting
Study tumor DNA changes during robot surgery after radiation
This study looks at how a cancer’s DNA changes over time in people who had head and neck cancer treated with radiation and then need robot-assisted surgery. It may help doctors understand why some cancers come back or persist and how to better plan treatment.
LondonAges 19 years+ - NCT04675476Recruiting
Phone and clinic support to help with lung screening
This study tests a patient-and-provider program to improve lung cancer screening for people who have missed appointments or did not follow through. It may help you get back on track with lung screening after a longer gap.
Washington D.C., District of ColumbiaAges 50–80 - NCT04676828Recruiting
SPECT-guided radiation to avoid healthy lung in lung cancer
This study tests a special imaging-guided radiation plan that aims to treat lung cancer while reducing radiation to healthy lung tissue. It may help lower lung side effects while keeping the cancer treatment focused on tumor areas.
Sydney, New South WalesAges 18 years+ - NCT04679454Recruiting
One-dose pre-surgery radiation for early breast cancer
This study tests whether giving a single dose of radiation before breast surgery can be safe and effective for early-stage breast cancer. It may help by shrinking or treating the tumor right before the operation, depending on your case.
MilanAges 18 years+ - NCT04678427Recruiting
Exercise program for kids and young adults in stem cell transplant
This trial tests whether a structured exercise program (“TEAM Me”) can improve movement and mobility during and after a blood stem cell transplant in young people with cancer. It may help reduce stiffness and weakness so you can move more comfortably during treatment.
Dallas, TexasAges 6–29 - NCT04687631RecruitingPhase 3
Study drug for colorectal cancer that spread to the liver
This Phase 3 trial tests a treatment approach for colorectal cancer that cannot be removed with surgery at first but has spread only to the liver. It is intended for people whose tumor is RAS/BRAF “wild-type” and who are well enough to do daily activities, to see if the treatment can control the cancer better.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04687956Recruiting
Preventing arm swelling after breast cancer lymph node surgery
This study looks at ways to prevent arm swelling (lymphedema) related to breast cancer after surgery to remove lymph nodes. It may help people who are getting axillary lymph node dissection lower the chance of long-term swelling.
SeoulAges 19 years+ - NCT04689347RecruitingPhase 1/Phase 2
New chemotherapy and targeted drug for a specific colon cancer type
This trial tests a combination of chemotherapy (5-FU/LV, irinotecan, and temozolomide) plus bevacizumab in metastatic colon or rectal cancer. It focuses on tumors with an “MGMT silenced” pattern (MGMT gene turned off), which may make some cancers more responsive to these medicines.
Milan, MilanAges 18–75 - NCT04689802Recruiting
Study urine tests to help screen for cancer
This study looks for a new set of urine “markers” (measurable substances in urine) that may help detect cancer earlier. If you join, they will collect your urine and compare results between people with cancer and people without cancer.
ShatinAges 18 years+ - NCT04691284Recruiting
Test how the gut microbiome changes during major cancer treatment
This study looks at your gut “microbiome” (the bacteria in your intestines) while you receive high-dose chemotherapy and a stem cell transplant, or CAR-T cell therapy. Researchers hope to understand how these treatments affect the microbiome, which may relate to how well patients do.
Bratislava, SlovakiaAges 18 years+ - NCT04694924Recruiting
Prostate cancer patient registry to track experiences
This study builds a database of people with localized or locally advanced prostate cancer to better understand patient-reported outcomes (your experiences and quality-of-life). It may help improve future care by collecting consistent feedback from patients.
Dendermonde, Oost-VlaanderenAges 18 years+ - NCT04696081Recruiting
Atrial fibrillation treatment in people with active cancer
This trial studies atrial fibrillation (an irregular heartbeat) in adults who have active cancer. It looks at people whose atrial fibrillation started after their cancer diagnosis or returned after cancer diagnosis.
