Additional Chemotherapy Administered Directly Into the Liver Using a Chemo Pump in Patients With Bile Duct Cancer Inside the Liver Treatable by Surgery

This study adds chemotherapy delivered directly into the liver's blood supply (via a pump implanted during surgery) to standard treatment for people with a type of bile duct cancer located inside the liver that can be surgically removed. The goal is to reduce the chance the cancer comes back. **You may be eligible if...** - You are 18 or older - You have bile duct cancer inside the liver (intrahepatic cholangiocarcinoma) that appears removable by surgery on imaging scans - You are healthy enough to undergo open abdominal surgery - The anatomy of your liver's blood supply makes pump placement technically possible **You may NOT be eligible if...** - Your cancer has spread outside the liver - You have significant other health problems that make surgery too risky - You have certain blood vessel abnormalities that prevent safe pump placement Talk to your doctor to see if this trial is right for you.
