Hepatic resection for colorectal metastases

The liver represents a common site for metastasis in colorectal cancer. Improvements in patient selection and surgical techniques has resulted in improved outcomes following hepatic metastasectomy with large series reporting 5- and 10-year overall survival rates of 40% and 20%, respectively. In recent years, criteria for resectability has expanded with the use of forced liver hypertrophy and staged resection. The role of perioperative chemotherapy remains controversial with a slight increase in survival and operative morbidity.
