This trial tests a “master protocol” approach to use MRI (a detailed body scan) to help plan radiation treatment for people with cancer. It may help doctors customize radiation more accurately, depending on your specific cancer type.
Boston, MassachusettsAges 18 years+ - NCT04547166RecruitingPhase 2/Phase 3
New targeted immune drug plus bevacizumab and chemo for colon cancer
This trial studies serplulimab (an immune-related drug) together with bevacizumab and chemotherapy to treat metastatic colorectal (colon) cancer that cannot be removed with surgery. It aims to see whether this combination improves outcomes and is safe.
Guangzhou, GuangdongAges 18–75 - NCT04547816RecruitingPhase 3
Non-surgical treatment for constipation-related prolapse in women
This study tests whether a non-surgical (“conservative”) approach can improve constipation-related bowel problems in women who have a mild-to-moderate rectal bulge from pelvic organ prolapse. It may help by addressing how the rectum and pelvic floor work during bowel movements.
MoscowAges 18–70 - NCT04547725Recruiting
Surgery plus chemotherapy for stomach cancer in the belly lining
This study tests whether a thorough surgery to remove stomach cancer in the abdomen, followed by chemotherapy given through the belly and by vein, can improve outcomes. It’s for people newly diagnosed with stomach cancer that has limited spread to the belly lining.
TaipeiAges 20–75 - NCT04556019Recruiting
Study of past and future liver and bile-pancreas surgeries
This is a research study using information from people who had certain liver, bile duct, and pancreas surgeries in the hospital’s surgical team. It aims to review surgical results and may help improve how these operations are done.
Pamplona, NavarreAges 15–90 - NCT04557969Recruiting
Surgery and tumor testing in gastrointestinal stromal tumors (GIST)
This study looks at how surgery for gastrointestinal stromal tumors (GIST) works, and collects tumor samples to study them under the microscope and by DNA testing. Your results may help researchers better predict tumor behavior and guide future treatment.
Bethesda, MarylandAges 6 years+ - NCT04571294Recruiting
Removing lymph nodes during Whipple surgery for pancreatic cancer
This study looks at removing certain lymph nodes near the aorta while doing a standard Whipple operation for pancreatic head cancer. The goal is to see whether this approach can improve how well doctors manage the cancer spread.
Rozzano, Italy/MilanAges 18 years+ - NCT04573283Recruiting
Study of fatty liver in adults in China
This study follows adults with fatty liver to learn more about how it progresses and what patterns are common. It may help improve future ways of identifying and monitoring fatty liver.
Guangzhou, GuangdongAges 18–80 - NCT04578301Recruiting
Predicting who develops serious liver worsening after surgery
This study looks at your liver health before and after surgery to predict the risk of “acute-on-chronic liver failure,” which means a sudden worsening of liver function on top of an existing liver condition. If you qualify, your doctors may use study data to better identify who needs closer monitoring after surgery.
BonnAges 18 years+ - NCT04578769Recruiting
Testing two modified POEM methods for achalasia
This study compares different versions of a procedure called POEM for treating achalasia, a condition where the food pipe has trouble moving food into the stomach. You may be considered if you have specific achalasia types and symptoms that are still significant despite treatment.
