Abstract: The liver is the main target organ for hematogenous metastases of colorectal cancer, and colorectal liver metastasis is one of the most difficult and challenging situations in the treatment of colorectal cancer. In order to improve the diagnosis and comprehensive treatment in China, the Chinese guidelines for diagnosis and comprehensive treatment of colorectal liver metastases have been edited and revised for several times since 2008, with a view to guiding comprehensive evalua-tion of patients with colorectal liver metastases, accurately formulating personalized treatment goals and comprehensive treatments, so as to prevent the occurrence of liver metastases, increase the local damage rate of liver metastases, prolong long-term survival, and improve quality of life. The revised Chinese guidelines for diagnosis and comprehensive treatment of colorectal liver metastases (2023 edition) includes the diagnosis and follow-up, prevention, multidisciplinary team, surgery and other destructive treatment, neoadjuvant and adjuvant therapy for the "no disease evidence" state of colorectal liver metastases, comprehensive treatment for colorectal liver metastases which can not reach the "no disease evidence" state. The consensus collects and summarizes the advanced experi-ence and latest achievements in this field at home and abroad, with detailed contents and strong operability.
