[Surgical treatment of colorectal liver metastases]

Surgical resection of the metastases offers the only opportunity for long-term survival in colorectal liver metastases. However, only 10% to 20% of patients present with resectable disease, and so how to increase surgical patients has been a clinical hotspot. In addition to expanding surgical indications, two-stage hepatectomy and convertible therapy are optional. In convertible therapy, initial treatment regimen decides long-term benefit, and it is important to select appropriate patient population in addition to Ras status when anti-epithelial growth factor receptor monoclonal antibody is used. Minimally invasive surgery can also be used for liver resection and simultaneous resection, and it is safe and effective. For patients with colorectal cancer and unresectable asymptomatic liver metastases, the debate continues over the efficacy of primary resection compared to chemotherapy alone, limited by lack of prospective evidence. Therefore, multidisciplinary team assessment is essential to optimize outcomes in colorectal liver metastases.
