Transarterial chemoembolization (TACE) is the administration of a chemotherapeutic agent through an artery directly to a cancerous tumor in the liver, followed by the embolization of the blood vessels feeding the cancerous tumor, causing interruption of blood. This is a palliative treatment for patients not eligible for surgery. However, a portion of viable cancer cells may remain and new feeding vessels can grow from surrounding tissue. Therefore, it is necessary to undergo repeated sessions at 6- to 8-week intervals to eliminate the remaining cancer cells.
