Surgical management for metastatic liver tumors.

Abstract

These results show that hepatectomy may offer longer survival, even in patients with multiple or bilobar metastases. Neither the operative procedure nor the size of the surgical margin had any influence on survival after hepatectomy. The prognosis was improved not only for metastases from colorectal cancer, but also for gastric cancer. An increased survival benefit was obtained by repeat hepatectomy for recurrent hepatic metastases. Preoperative portal embolization extended the indication for hepatectomy and provided postoperative safety.
