Liver Transplantation for Colorectal Cancer

This is an observational study that will follow adults with stage IV colorectal cancer whose disease has spread only to the liver (not to other organs) and who are undergoing a liver transplant as part of their cancer treatment. Liver transplantation is being offered as a potentially curative option for patients whose liver metastases cannot be surgically removed. Researchers will review participants' medical records for up to 5 years after transplant to understand how this treatment affects survival, cancer recurrence, and safety. Participants will also be asked to complete a quality-of-life questionnaire (EORTC QLQ-C30). Taking part in this study does not involve any additional tests, visits, or procedures beyond the standard care participants would otherwise receive.
