Transcatheter hepatic arterial embolization therapy (TAE) is an established method for the treatment of hepatocellular carcinoma (HCC). We have developed a new embolus consisting of microspheres with a mean diameter of about 200 microns which are composed of biodegradable polymolecular polylactic and the anti-cancer agent, aclarubicin -HCl, in a ratio of 12% w/w. These microspheres were applied to 28 patients with inoperable HCC using the following method microspheres containing 50 mg of aclarubicin-HCl were injected through a catheter placed in the hepatic artery or one of its branches, 2 or 3 times at intervals of 2 to 4 weeks. The effectiveness was confirmed by decreased levels of serum AFP and regression of the tumor size, and the accumulated survival rate for 6 months was 83.3%.

D002404 Catheterization Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions. Cannulation,Cannulations,Catheterizations
D004621 Embolization, Therapeutic A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.

D006528 Carcinoma, Hepatocellular A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.
