TACE group: The frequency of treatment is determined based on the disease condition at a 4-6 weeks interval for patients who are randomly assigned to group of TACE treatment. TACE is performed via an injection into the hepatic artery of agents by puncturing the common femoral artery, and micro-embolization superselective catheterization is preferred. Adriamycin(30 to 60mg) is considered as basic chemotherapy drugs in the process of transcatheter endovascular perfusion.The dose of lipiodol was determined by diameter and blood supply type of HCC,generally 5-20ml,and no more than 30ml once.The boundary is considered whether there are large amounts of lipiodol to deposit in the tumor and tiny branches shadow of portal veins in paracarcinoma under fluoroscopic guidance. Embolizing agents(gelatin sponge particles 350um-560um) are added after lipiodol emulsion embolization. And all the blood supplies of the tumor should be embolized as far as possible.
