The liver is the most common site of metastasis in colorectal cancer (CRC). Treatment of liver metastases
determines the prognosis of patients with CRC. Tremendous progress has been made during the last two
decades, which has greatly improved the overall survival of CRC patients. Currently, various treatment
options are available, including hepatectomy, liver transplantation, local regional therapy, chemotherapy,
targeted therapy, and immune therapy, inevitably leading to some controversies on treatment indications
and selection of treatment strategy. Here, we reviewed the existing approaches to treat colorectal cancer
liver metastases, with the aim of examining several crucial questions regarding surgical resection, liver
transplantation, and medical treatment in clinical practice.
