Liver metastasis of bowel cancer can be treated with surgery, chemotherapy and targeted therapy, transformational chemotherapy and palliative therapy. 1. Surgical treatment: for liver metastases that can be resected in one stage, surgery can be performed laparoscopically to remove the colon cancer, and lymphatic cleansing should also be performed. If it cannot be resected in one stage, two-stage surgery can be considered. 2. chemotherapy and targeted therapy: chemotherapy and targeted therapy can be carried out after surgery. 3. Conversion therapy: if there are many liver metastases that cannot be resected in one stage, conversion therapy can be carried out first, and then review after a period of time. 4. Palliative therapy: for patients with extensive metastases who cannot undergo surgery. If liver metastasis of intestinal cancer is diagnosed, early and standardized treatment is recommended to avoid delay.
