title: Surgical resection of liver metastases from colo-rectal cancers.
abstract: Surgical resection is currently the only potentially curative treatment in some selected patients with colo-rectal liver metastases (LM). Unfortunately only a minority of patients are candidates for resection. Only solitary or unilobar LM that can be removed by partial liver resection, are considered to be resectable. The second condition for the resection of LM is that the primary cancer must be resected. The third condition for resection is that the patient must be able to undergo a major liver resection if it is necessary. Small metastases which do not exceed 5 cm, and appear on the surface of the liver can be removed by a simple wedge resection. If the tumor is larger than 5 cm, or if multiple unilobar nodules are discovered, a major liver resection becomes necessary. Hospital mortality does not exceed 5% in most published series. Five year survivals are very rare when histologically proven colo-rectal LM are left in place. After surgical resection of LM, five year survival rates are close to 25% and range from 18% to 52%. Surgical resection is of benefit to approximately one fourth of the patients, who survive five years or more, but three fourths of the patients have early recurrences. None of the studied criteria can predict which patients will benefit from surgical resection of LM. In order to try to reduce the rate of early recurrences adjuvant chemotherapy has been proposed. No positive data have yet been obtained.
