BudapestAges 18–65 - NCT04358913Recruiting
MRI scan study during radiation treatment planning
This study looks at how an MRI scanner can be used alongside a radiation treatment machine to plan therapy. It may help improve how radiation is targeted, though joining is mainly about whether you can safely and comfortably complete the MRI scans.
Edmonton, AlbertaAges 18 years+ - NCT04361708RecruitingPhase 1
Test drug combo chemotherapy for advanced pancreas and upper GI cancers
This early-phase study tests how safe and workable it is to combine irinotecan with several standard chemotherapy medicines for cancers like pancreatic and other upper GI cancers. It’s mainly looking for side effects and the best way the doses work in people with advanced or metastatic disease.
Chicago, IllinoisAges 18 years+ - NCT04362046Recruiting
Fertility-friendly treatment for early uterine cancer or precancer
This trial studies whether removing an early, hormone-responsive uterine growth using a procedure through the cervix can keep fertility possible. It is for people under 40 with a specific low-risk uterine biopsy and MRI findings who have already tried hormone treatment.
Vancouver, British ColumbiaAges 19–39 - NCT04362826Recruiting
Trial tests a probiotic to change gut microbes in breast cancer
This study gives a probiotic to see whether it safely changes the gut’s bacteria and fungi (your “microbiome”) in people with breast cancer. The researchers want to learn if this shift in gut microbes might support breast cancer treatment or health during care.
Cleveland, OhioAges 18–65 - NCT04364373Recruiting
Test of different lymph node surgery for left colon cancer
This study compares two types of lymph node removal during surgery for left-sided colon cancer. It aims to see which surgical approach may work better while ensuring you can still safely complete chemotherapy.
MoscowAges 18–75 - NCT04365751Recruiting
Microwave ablation versus surgery for liver cancer
This trial compares two ways to treat hepatocellular carcinoma (a type of liver cancer): microwave ablation and laparoscopic hepatectomy (keyhole liver surgery). It may help find which option works better for tumor control and recovery in people with limited, non-spread cancer.
Beijing, Beijing MunicipalityAges 18 years+ - NCT04367246Recruiting
TP53 (Li-Fraumeni) family biobank and sample study
This study collects and stores health information and biological samples from people who have a known TP53 change (Li-Fraumeni syndrome) and from close family members. The goal is to help researchers learn more about risks and future treatments for this genetic condition.
Philadelphia, PennsylvaniaAges Any age - NCT04368702Recruiting
MRI-guided radiation for people needing radiation for cancer
This study tests whether radiation given with help from MRI (a type of scan) can better treat cancers that need radiation. You may be eligible if your cancer is confirmed and you can safely have MRI scans.
Boston, MassachusettsAges 18 years+ - NCT04369560RecruitingEarly Phase 1
Virtual MRI to map bladder cancer for staging before surgery
This early-stage study uses special MRI imaging to create a “virtual view” of the bladder wall so doctors can better stage bladder cancer before treatment. If you qualify, you may get MRI imaging using contrast medicines as part of planning your surgery.
Pittsburgh, PennsylvaniaAges 18–90 - NCT04370496Recruiting
Testing minimally invasive endoscopic stapler surgery for early cervix cancer
This trial tests how safe a specific minimally invasive surgery tool (an endoscopic stapler) is for people with early-stage cervical cancer. If you qualify, you would get surgery to remove the cervix area using a minimally invasive approach and the study will track safety outcomes.
SeoulAges 20 years+ - NCT04370587RecruitingPhase 1/Phase 2
Injecting a cancer medicine into tumors plus pembrolizumab
This Phase 1/2 study tests a medicine injected directly into a tumor, alone or with pembrolizumab (an immune-therapy drug given through a vein). It is for people with advanced or metastatic solid cancers that have grown despite standard treatments, aiming to improve tumor control.
Gilbert, ArizonaAges 18 years+ - NCT04370574Recruiting
Testing blood or tissue markers for suspected pancreatic cancer
This trial looks for “soluble biomarkers” (markers that can be found in body fluids like blood) for people who have a pancreatic mass and may have pancreatic ductal adenocarcinoma. The goal is to improve how pancreatic cancer is identified, especially using information taken from an endoscopic ultrasound biopsy.
Montpellier, MontpellierAges 18 years+ - NCT04371913Recruiting
Second chance breast-conserving treatment for certain breast recurrences
