 Patients enrolled in the study will be administered MTC-DOX through a hepatic artery catheter inserted under radiological guidance. During and following injection of the MTC-DOX, the drug will be localized to the hepatic tumor site by use of an external magnet. Dose may be divided in order to localize MTC-DOX to all lesions. The MTC-DOX intrahepatic infusions will be repeated every three weeks until tumor progression, complete remission, unacceptable toxicity, or a maximum of six treatment cycles.
