[Intra-arterial infusion of SMANCS for treatment of patients with hepatocellular carcinoma--adverse reactions and complications].

Although intra-arterial infusion of SMANCS has been demonstrated to be highly effective for treatment of patients with hepatocellular carcinoma, it is reported to cause critical adverse reactions and complications. We examined the adverse reactions of SMANCS on the hepatic artery in 78 patients with hepatocellular carcinoma, who were infused with SMANCS from right, left or proper hepatic artery at our hospital. SMANCS caused right hepatic artery occlusion in 15 patients (19%) and the average amount of infused SMANCS was 6.8 mg. The tumor volume in the artery occluded patients was smaller than that in the artery non-occluded patients. Then, the mechanism by which SMANCS caused arterial occlusion was its induction of arterial injuries by excess infusion. When SMANCS was infused to whole liver, it induced decreased hepatic functional reserve and liver atrophy, followed by delayed liver failure. Other adverse reactions were no different from those in patients infused with epirubicin-lipiodol emulsion.
