MALIGNANT DIGESTIVE SYSTEM NEOPLASM

This phase I/II trial tests whether vasodilator drugs (isosorbide mononitrate or diltiazem) can prevent blood vessel damage caused by fluoropyrimidine chemotherapy in 60 patients with gastrointestinal cancer. Researchers will monitor blood vessel reactivity using a non-invasive d…

This study tracks 150 gastrointestinal cancer patients with a narrowed portal vein who receive a stent to keep the vein open. Researchers will monitor how long the stent stays clear, changes in liver function, nutrition, bleeding risk, and quality of life. The goal is to see if s…

This study tests whether a special algorithm called PAGODA can reduce unplanned delays during FOLFOX chemotherapy for gastrointestinal cancers like colon, stomach, and esophageal cancer. About 420 participants will be randomly assigned to either standard care or the algorithm-gui…

This study is collecting information on side effects from proton therapy in 5,000 adults with many types of cancer. Researchers will track both short-term and long-term side effects and link them to the details of each patient's treatment plan. The goal is to better predict who m…

This study collects tissue and blood samples from 1,500 people with biliary tree cancers, plus healthy volunteers, to look for genetic changes and risk factors. Researchers hope to build models that predict how the cancer develops and responds to treatment. The goal is to better …

This study surveys 500 surgeons and advanced practice providers across the U.S. to see how often they prescribe blood thinners after cancer surgery to prevent dangerous blood clots. The goal is to understand current practices and find ways to improve care. No new treatments are b…
