Liver metastases from colon cancer are stage IV colon cancer, and most of them require interventional treatment. The metastatic lesions in the liver are reached through an interventional tube, and chemotherapeutic drugs are infused, combined with thermal therapy and embolization of the metastatic lesions. The combination of these three techniques makes minimally invasive interventional treatment of metastatic lesions in the liver very effective. In addition, the combination of local surgery for intestinal cancer and interventional treatment for metastatic lesions of liver cancer can achieve better results even if liver metastases have already occurred.
