Clinical relevance of oncologic prognostic factors in the decision-making of pre-hepatectomy chemotherapy for colorectal cancer hepatic metastasis: the priority of hepatectomy.

Hence, liver resection should be attempted without delay at the initial detection of CRC hepatic metastasis whenever possible.
