Transcatheter arterial chemoembolization (TACE) in the treatment of unresectable liver cancer.

Basis, techniques, and recent strategies and results of interventional treatments for hepatoma were reviewed. The basic experimental researches indispensable to justify clinical technique and dosage have been accomplished. A total of 1310 unresectable cases underwent transcatheter arterial chemoembolization (TACE) and/or related therapies. The related therapies are several modified or strengthened TACE such as Lipiodol-TACE and subsegmental TACE. The therapies for unembolizable cases are balloon occluded arterial infusion, Lipiodol-SMANCS infusion and percutaneous direct injection chemotherapy, that reinforces the effect of TACE. As for the resectable cases, postoperative TACE was proved to be beneficial because it increased survival rates; however, preoperative TACE was not beneficial. The TACE and related interventional radiologic therapies for the hepatoma can be an equal or superior therapy by virtue of targeting chemotherapy.
