Microwave Ablation Versus Liver Resection for Intrahepatic Cholangiocarcinoma

This study compares two treatments for intrahepatic cholangiocarcinoma (a type of bile duct cancer inside the liver): microwave ablation (using heat to destroy the tumor) versus liver resection surgery (removing the part of the liver with the tumor), to see which offers better outcomes for appropriate patients. **You may be eligible if...** - You are 18 or older with a confirmed diagnosis of intrahepatic cholangiocarcinoma - Your tumor meets 'Milan criteria': a single tumor ≤5 cm, or up to 3 tumors each ≤3 cm - There is no evidence of spread to major blood vessels, lymph nodes, or other organs - You are able to undergo either liver surgery or ablation with curative intent **You may NOT be eligible if...** - Your tumor exceeds the size/number limits stated above - Your cancer has spread to lymph nodes, blood vessels, or other parts of the body - You otherwise don't meet the inclusion criteria Talk to your doctor to see if this trial is right for you.
