chemoembolization of non-resectable non-metastatic hepatocellular carcinoma using embolization microspheres

Conditions: Localized Non-Resectable Adult Hepatocellular Carcinoma

Summary: chemoembolization is a recognized treatment strategy for hepatocellular carcinoma (hcc) * classical chemoembolization consists in injecting an emulsion of an anticancer agent in lipiodol® via the hepatic artery * doxorubicin, an anthracycline, is the most frequently used drug in lipiodol chemoembolization (lce) * however, less than half of hcc respond favourably to classical lipiodol chemoembolization (lce) with doxorubicin/lipiodol® in this trial, we propose to introduce in clinical practice a strategy based on idarubicin to achieve a more effective antitumor effect for the following reasons, recently pointed out by our team: * idarubicin is an anthracycline that penetrates tumour cells more quickly and is more cytotoxic than doxorubicin on hepatocellular carcinoma cell lines * idarubicin is injected in a solution of embolization microspheres of a diameter of (300-500µm), which all the progressive and controlled release of the anticancer drug, whereas the doxorubicin/lipiodol® emulsion is unstable
