Bowel cancer liver metastasis is mainly treated by surgery, intervention, radiotherapy, targeted therapy and immunotherapy. Bowel cancer generally refers to colorectal cancer, which refers to malignant tumors occurring in colon or rectum and can metastasize to liver. Colorectal combined liver metastasis is already in advanced stage, and the treatment is based on comprehensive treatment such as chemotherapy and radiotherapy as follows: 1. If the primary focus and liver metastasis can be resected, both can be resected together; 2. If the primary foci can be resected but the metastases cannot be resected, palliative resection can be performed on the primary foci, and the metastases can be given interventional therapy (e.g., transvascular chemoembolization, radiofrequency ablation, injection of anhydrous alcohol, etc.) or local radiotherapy; 3. If the primary foci cannot be removed, “short-circuit” surgery or stoma surgery is feasible. In addition, after surgical treatment, patients need to choose chemotherapy (commonly used drugs such as 5-fluorouracil, capecitabine, etc.), radiotherapy (the use of energy released by rays to kill tumor cells), targeted therapy, immunotherapy and so on according to the situation. In conclusion, colorectal combined liver metastasis is advanced and requires comprehensive treatment. It is recommended to go to the regular hospital for a comprehensive assessment of the condition, choose the appropriate treatment plan according to the situation, and follow the doctor’s instructions to actively cooperate with the treatment, so as not to delay the condition.
