Radiation plus targeted drugs for advanced pancreatic cancer
This trial tests a combination of targeted radiation and two oral drugs (defactinib and avutometinib) for people with advanced pancreatic cancer that hasn't spread to distant organs. It may be an option if you've already had at least 2 months of chemo and your cancer is still locally advanced or borderline resectable.

Madison, WisconsinAges 18 years+ - NCT03401294RecruitingPhase 2
Turn unresectable liver cancer into operable colorectal cancer
This Phase 2 study tests a treatment strategy to shrink or control colorectal cancer that has spread only to the liver, with the goal of making it removable by surgery. If you qualify, it may offer a chance to move from “not operable” to “operable,” but it’s still experimental.
Regina, SaskatchewanAges 18–70 - NCT06784765Recruiting
Preventive PIPAC for advanced stomach cancer
This trial tests if a special type of chemotherapy delivered as a mist during surgery (PIPAC) can help prevent the spread of stomach cancer. It is for people with advanced but not yet metastatic stomach cancer who have not had prior treatment.
AstanaAges 18 years+ - NCT06878209Recruiting
Cough and hemorrhoids study
This study looks at how coughing may relate to hemorrhoids. Researchers want to understand the possible connection in people who have hemorrhoids but haven't had surgery for them.
Muğla, MenteşeAges 18 years+ - NCT07121803Recruiting
Special ice cream for esophagus health in diabetes
This study tests whether a special ice cream can help the esophagus (the tube that carries food to your stomach) work better in people with type 2 diabetes. Researchers want to see if the ice cream can improve how food moves down the esophagus.

Robot vs standard keyhole gallbladder surgery for non-cancerous disease
This trial is comparing two types of keyhole surgery for removing the gallbladder: one done with a robot and the other with standard laparoscopic tools. The goal is to find out which technique leads to a better recovery and fewer complications for people with non-cancerous gallbladder problems like gallstones or polyps.

Targeted chemo into liver for colorectal cancer spread
This trial is testing a new way to give the chemotherapy drug paclitaxel directly into the liver (through a tiny tube) along with standard systemic treatment for people whose colorectal cancer has spread only to the liver and cannot be surgically removed. The goal is to see if this targeted approach works better than standard treatment alone.
