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.
