Hepatocellular Carcinoma: Intra-arterial Delivery of Doxorubicin-loaded Hollow Gold Nanospheres for Photothermal Ablation-Chemoembolization Therapy in Rats.

ABSTRACT: Purpose To determine if combretastatin A-4 phosphate disodium (CA4P) can enhance the tumor uptake of doxorubicin (Dox)-loaded, polyethylene glycol (PEG)-coated hollow gold nanospheres (HAuNS) mixed with ethiodized oil for improved photothermal ablation (PTA)-chemoembolization therapy (CET) of hepatocellular carcinoma (HCC) in rats. Materials and Methods Animal experiments were approved by the institutional animal care and use committee and performed from February 2014 to April 2015. Male Sprague-Dawley rats (n = 45; age, 12 weeks) were inoculated with N1S1 HCC cells in the liver, and 8 days later, were randomly divided into two groups of 10 rats. Group 1 rats received intrahepatic arterial injection of PEG-HAuNS and ethiodized oil alone; group 2 received pretreatment with CA4P and injectio
