 Transarterial chemoembolization TACE is the major modality utilized for tumor downstaging for transplant and for local therapy in non-transplant patients. This procedure allows delivery of concentrated drugs to the tumor, followed by embolization that eliminates its blood supply creating an environment of hypoxia. The process induces tumor ischemia, while achieving a drug concentration in the tumor 10 to 25 times greater than can be achieved by infusion.
