Fabrication of Glyco‐Metal‐Organic Frameworks for Targeted Interventional Photodynamic/Chemotherapy for Hepatocellular Carcinoma through Percutaneous Transperitoneal Puncture

Abstract Hepatocellular carcinoma (HCC) causes high morbidity and mortality due to a lack of adequate treatments. Cancer treatments have benefited from nanotechnology approaches that integrate multimodal synergistic therapies. A synergistic, minimally invasive strategy of interventional photodynamic therapy (IPDT) and chemotherapy for HCC treatment through percutaneous transperitoneal puncture is disclosed that is based on photosensitive porphyrinic galactose‐modified metal‐organic frameworks (PCN‐224) first used as hepatic targeting and encapsulated with anticancer drug doxorubicin (DOX@Gal‐PCN‐224). Real‐time imaging reveals the effective accumulation of the integrated nanosystem in the HCC cells and tumor tissues due to hepatic targeting. Evaluation of the anti‐tumor efficiency of this nanosystem on orthotopic transplantation tumors with the aid of minimally invasive intervention shows a tumor inhibition rate of 98%. The synergistic effects induce high‐level cell apoptosis and tissue necrosis in vitro and in vivo. This bimodal IPDT/chemotherapy strategy holds great potential in the clinical treatment for HCC.
