Registry study for pancreatic ductal cancer before treatment
This is a “registry” study that collects health information from adults with pancreatic ductal adenocarcinoma before starting treatment. It may help researchers better understand the disease and how patients are managed in real life.
UlmAges 18 years+ - NCT02724670Recruiting
MRI-guided radiation for prostate cancer patients
This study tests radiation treatment planned and guided using MRI scans (“image-guided radiotherapy”) for men with prostate cancer who are aiming for a cure. If you qualify, you may receive radiation with more precise targeting using MRI to help deliver treatment accurately.
TübingenAges 18 years+ - NCT04063527RecruitingPhase 3
Stage I ovarian cancer treatment after surgery
This trial studies whether an additional treatment after surgery can help people with early-stage epithelial ovarian cancer live longer and stay well for more time. It is meant for patients who had a detailed staging operation and are able to start treatment within 8 weeks.
Nagakute-shi, Aichi-kenAges 20 years+ - NCT04076449Recruiting
MRI measurements for epilepsy from a single brain blood vessel lump
This study uses special MRI scans to measure brain changes in people whose seizures are related to one cerebral cavernous malformation (a type of abnormal blood vessel in the brain). It aims to find a measurable “biomarker” from MRI that may help understand the epilepsy and the brain structure around it.
Beijing, Beijing MunicipalityAges 18–70 - NCT04135664RecruitingPhase 3
Compare surgery vs chemoradiation for early throat cancer
This study compares two ways to treat a type of esophagus cancer: surgical removal (esophagectomy) versus chemoradiation (chemo plus radiation). It is for people with early-stage findings where scans suggest no lymph node spread.
Nanchang, JiangxiAges 18–75 - NCT03975322Recruiting
Predict which oral white patches may turn cancerous
This study looks at oral leukoplakia (persistent white patches in the mouth) to better predict which ones may develop into cancer. It uses a test based on specific immune and cancer-related markers to help estimate each person’s risk.
ErlangenAges 18–80 - NCT04209244Recruiting
Fish oil for cholesterol and side effects in ALL patients
This trial studies whether fish oil can improve cholesterol levels and reduce side effects in children and young adults with acute lymphoblastic leukemia (ALL) who are in lower-risk groups. If you fit the risk category, you may be asked to add fish oil as part of the study to see if it helps your lab results and well-being.
AalborgAges 1–45 - NCT04136886RecruitingPhase 3
Chemo trial for return of advanced nasopharyngeal cancer
This Phase 3 study tests a chemotherapy plan for people whose nasopharyngeal cancer has come back locally (T3/T4). It aims to see if treatment given after return of cancer can help control the disease without spreading to distant organs.
Guangzhou, GuangdongAges 18–70 - NCT04149496Recruiting
IVF cycle study using modified egg-retrieval timing
This study tests an IVF approach that changes how ovarian stimulation is started, helps retrieve eggs more effectively, and may delay embryo transfer. It may help people who have many small eggs (called antral follicles) and higher AMH levels, which can affect how IVF works.
Jacksonville, FloridaAges 18–38 - NCT04172753Recruiting
Online MRI-guided radiation therapy on a 1.5T machine
This trial checks whether it’s practical and safe to deliver radiation treatment using real-time MRI guidance, with the process supported online. It may help patients whose doctors recommend radiation by testing a modern way to plan and deliver treatment more precisely.
Tübingen, Baden-WurttembergAges 18 years+ - NCT04217512RecruitingPhase 3
Pantoprazole to protect kidneys during head and neck cancer treatment
This trial tests whether pantoprazole can help prevent kidney damage caused by a chemotherapy drug called cisplatin. It may help protect kidney function in people with head and neck cancer receiving cisplatin.
TantaAges Any age - NCT04157569Recruiting
Study blood DNA markers after chemotherapy in older acute leukemia
This trial checks a blood test called “ctDNA” (tiny pieces of leukemia DNA in blood) after chemotherapy. It may help doctors understand how well treatment is working in older adults with acute leukemia.
BeijingAges 60–100 - NCT04197414Recruiting
Urology DNA registry to personalize cancer care
This study builds a urology cancer “DNA registry” by analyzing circulating tumor DNA found in the blood. Your information and permission help researchers better personalize treatment for cancers like prostate, kidney, bladder, and ureter cancer.
SeoulAges 20 years+ - NCT04212715RecruitingPhase 2
Extra radiation boost for high-risk prostate cancer
This Phase 2 study tests a treatment plan that uses standard focused radiation to the prostate, plus an extra “boost” delivered inside the prostate. It may help improve control of high-risk prostate cancer, especially by aiming radiation more precisely.
RiyadhAges 18–99 - NCT04356235Recruiting
Comparing immediate vs delayed breast implant reconstruction results
This study compares two timing options for rebuilding the breast with implants, looking at cosmetic results, quality of life, and patient satisfaction. It may help you understand which approach could fit you better and what to expect over follow-up time.
BudapestAges 18–65 - NCT03804320Recruiting
Watching small kidney tumors over time instead of treating
This study follows people with small, solid kidney tumors using active surveillance (regular monitoring) rather than immediate surgery or treatment. It may help you understand whether careful watching is a safe option for certain early kidney tumors.
MilanAges 50 years+ - NCT04086290RecruitingPhase 1/Phase 2
Surgery plus targeted radiation for prostate cancer spread
This study looks at whether combining prostate surgery with a highly focused radiation treatment (SBRT) can control prostate cancer that has spread to a limited number of bones. It may help patients by treating the main tumor and the specific metastatic spots in a controlled way.
HerlevAges 18 years+ - NCT04278469Recruiting
Study for early breast cancer patients with low-risk genes
This trial studies early, hormone receptor–positive, HER2-negative breast cancer and looks at a group with “high clinical risk” but “low genetic (tumor) risk.” It may help researchers understand which patients may benefit most from treatment decisions guided by genetic tumor testing.
SeoulAges 19–80 - NCT04286841Recruiting
Immunotherapy before lung surgery for early lung cancer
This trial looks at giving immunotherapy before surgery for certain early-stage lung cancers to help shrink the tumor and improve outcomes. It is mainly for people whose lung cancer can be removed by surgery and who don’t have specific gene changes like EGFR or ALK.
Guangzhou, GuangdongAges 18 years+ - NCT03793517RecruitingPhase 2/Phase 3
Decitabine plus chemotherapy before stem cell transplant for high-risk leukemia
This trial studies whether adding decitabine plus chemotherapy before a stem cell transplant can better control “minimal residual disease” (very small amounts of leukemia left behind) in certain high-risk acute leukemia types. It may help reduce the chance of the leukemia coming back after transplant.
Beijing, Beijing MunicipalityAges 18–55 - NCT04316039RecruitingPhase 2/Phase 3
Radiation alone or with temozolomide for brain tumor after surgery
This trial compares standard radiation therapy versus radiation plus a chemotherapy medicine called temozolomide in people with a newly diagnosed low-grade (WHO grade II) brain glioma after surgery. It’s designed to see if adding temozolomide improves outcomes while managing side effects.
Chengdu, SichuanAges 18–70 - NCT04330456Recruiting
Radiation plus surgery for first soft tissue sarcoma
This trial studies a treatment plan for newly diagnosed soft tissue sarcoma that combines precisely targeted radiation before surgery and conformal radiation after surgery. It may help by improving tumor control while allowing the surgeon to remove the tumor safely.
Saint PetersburgAges 18–75 - NCT04349527Recruiting
Comparing breast-conserving surgeries and how you feel after
This trial compares two breast-conserving surgery techniques to see how they affect cosmetic results (how the breast looks), quality of life, and patient satisfaction. It may help guide the best surgical approach for people eligible for breast conservation.
BudapestAges 18–65 - NCT04345081Recruiting
Compare two breast surgery skin-sparing methods and recovery
This trial compares two types of mastectomy (with skin and nipple options) and implant reconstruction to see which gives better cosmetic results, comfort, and satisfaction. You may help doctors learn which approach leads to a better quality of life after surgery.
