New risk tool could predict cancer return after liver surgery

This observational study aims to develop a system that combines genetic and clinical data to predict which patients with colorectal cancer that has spread to the liver are at high risk of the cancer coming back after surgery. Researchers will study 200 adults aged 18-75 who have had complete removal of both the colon tumor and liver metastases. The goal is to use this risk information to guide personalized decisions about whether additional chemotherapy after surgery would be helpful.
