Bowel cancer metastasis to liver can be treated by surgery, targeted drug therapy, chemotherapy and tumor ablation. 1. Surgery: it is suitable for patients with less metastatic foci in liver, direct resection of liver metastatic foci or partial hepatectomy, and at the same time, resection of the primary foci of intestinal cancer. 2. Targeted drug therapy: applied after genetic testing of tumor, such as cetuximab is effective for patients with liver metastasis of bowel cancer with KRAS wild type, which should be taken according to doctor’s prescription. 3. Chemotherapy: Fluorouracil is commonly used, systemic intravenous chemotherapy can reduce the size of liver metastases and primary foci of intestinal cancer, improve the feasibility of resection, and transform the lesions from unresectable to resectable. Local chemotherapy via hepatic artery can also reduce the size of liver metastases. Adverse effects of chemotherapy drugs, such as gastrointestinal reactions, leukopenia, etc., should be used in accordance with medical advice. 4. Tumor ablation: for patients with multiple metastases in liver who have lost the chance of surgery, ablation treatments such as microwave, radiofrequency, cryotherapy and anhydrous alcohol injection can be carried out under the guidance of ultrasound or CT, so as to minimize the lesions. Patients with bowel cancer metastasized to liver should go to the hospital in time and choose appropriate treatment under the guidance of doctors.
