Improving Survival of COlorectal LIver Metastases by RFA-mediated Immunostimulation

This study is testing whether adding radiofrequency ablation (using heat to destroy tumor tissue) before standard liver surgery for colorectal cancer that has spread to the liver can help stimulate the immune system to fight remaining cancer cells, potentially improving survival. **You may be eligible if...** - You have colorectal cancer that has spread to your liver and are scheduled for surgery to remove it - At least one liver tumor is 3 cm or larger - You are in good general health (performance status 0-1) **You may NOT be eligible if...** - You have liver cirrhosis (severe liver scarring) - Your cancer has spread to other areas of the body that cannot be treated with curative intent - You have had another cancer within the past 5 years Talk to your doctor to see if this trial is right for you.
