Pharmacokinetics of intra-arterial mitomycin C in the chemoembolization treatment of liver metastases with polyvinylalcohol or degradable starch microspheres

Abstract

The AUC values found in this study do not indicate a reduction in the systemic toxicity of MMC if applied intra-arterially in combination with embolizing microspheres, when compared to the AUC values in the literature for intra-arterial application without embolization, or intravenous MMC application. The amount of starch microspheres may have been too small to cause marked effects. On the other hand, there is a very wide range of AUC values reported in the literature for different application modes, and the use of such historical controls is not adequate for detecting more subtle advantages of the chemoembolization procedure, which may, however, exist.
