Abstract    When liver metastases are diagnosed concurrently with the primary colorectal cancer, the timing of surgical intervention remains controversial. Traditionally most centers have adopted a staged treatment with the colorectal primary being dealt with first, followed by hepatic resection. However recently there has been increasing enthusiasm for synchronous surgical management, or in some cases, a liver first approach. Therefore, the surgical management of patients with synchronous colorectal metastases has not been clearly defined, still needs the support of high-level evidence. As for each patient, multidisciplinary therapy (MDT) should be advocated, in order to formulate individualized therapeutic regimen.
