Surgical treatment for colorectal liver metastases

Surgical resection is the treatment of choice for patients with colorectal liver metastases. The criteria for hepatic resection of colorectal liver metastases have been extended. Patients who were expected to have complete tumor resection, negative resection margin and adequate remnant liver volume could receive surgical resection. Surgical resection combined with local ablation can expand the resectability of liver metastases. There is no significant difference of long term survival between simultaneous and staged resection for colorectal and liver tumors. Laparoscopic surgery has been proved as safe and feasible for colorectal liver metastases. The survival benefits of adjuvant chemotherapy during perioperative period is unclear, and neo adjuvant chemotherapy might not benefit all the patients with colorectal liver metastases.
