Nearly one third of patients diagnosed with colon cancer are metastatic, that is, the cancer has already spread beyond the colon. The liver is the most common site for metastasis.
If surgery is not an option at diagnosis, your doctor may choose to give you liver directed or targeted therapies. Many liver directed therapies include ablation, embolization and internal radiation using yiitrium-90 microspheres. Liver directed treatments can be used alone or in combination with chemotherapy and/or biologic agents. After receiving these therapies, many patients become surgical candidates.
