Patients with colon cancer who have liver and lung metastases are a kind of advanced stage, and there are obvious differences in the survival time, and some patients can survive 1-3 years if treated effectively. For metastases in liver and lung tissues, systemic intravenous chemotherapy or interventional therapies, including ablation therapy or infusion chemotherapy, can be used, and changes in the patient’s internal environment should be monitored during treatment, as metastases are also prone to anemia and hypoproteinemia. The main purpose of post-treatment is to improve the patient’s quality of life and prolong the survival time. Colon cancer with liver and lung metastasis is also a common form of hematogenous metastasis, which has reached stage IV according to clinical stage.
