Abstract: The resection margin of liver metastases refers to the distance from the tumor edge to the liver section. The liver is the main target organ for distant metastasis of colorectal cancer. The issue of resection margin should not only follow the basic principles of liver surgery, but also consider the unique biological characteristics of colorectal liver metastases. Surgical resection margin is the focus and difficulty in surgical treatment. The definition of R0 resection has undergone a shift from a margin greater than 1 cm to greater than 1 mm. With further research, tumor R1 resection has gradually been proposed and accepted under specific conditions. High tumor burden, RAS gene mutations, tumor pathology, and vascular relationships are associated with higher R1 resection rates. This article intends to review and analyze the study of surgical margins for liver metastases in colorectal cancer.
