Large bowel cancer is a worldwide public health challenge.More than one third of patients present an advanced stage of disease at diagnosis and the liver is the most common site of metastases.Selection criteria for early diagnosis,chemotherapy and surgery have been recently expanded.The definition of resectability remains unclear.The presence of metastases is the most significant prognostic factor.For this reason the surgical resection of hepatic metastases is the leading treatment.The most appropriate resection approach remains to be defined.The two step and simultaneous resection processes of both primary and metastases have comparable survival long-term outcomes.The advent of targeted biological chemotherapeutic agents and the development of loco-regional therapies(chemoembolization,thermal ablation,arterial infusion chemotherapy) contribute to extend favorable results.Standardized evidence-based protocols are missing,hence optimal management of hepatic metastases should be single patient tailored and decided by a multidisciplinary team.This article reviews the outcomes of resection,systemic and loco-regional therapies of liver metastases originating from large bowel cancer.
