WITHDRAWN: Resection versus no intervention or other surgical interventions for colorectal cancer liver metastases.

About one in four of patients with metastatic colorectal cancer have metastases isolated to the liver, of which 10-25% are eligible for ablation of the liver metastases, improving the 5-year survival rate. Treatments include hepatic resection and non-surgical tumor ablation using cryosurgery and radiofrequency thermal ablation. Although new modalities allow safe ablation of liver metastases without the need for surgical intervention, there are still no clear guidelines on the appropriate management of patients with colorectal cancer and hepatic metastases.
