| Outline of Final Research Achievements |
Anticancer agents and operative procedures have been developed in patients with hepatocellular carcinoma (HCC), but the prognosis remained poorly. It is necessary to develop the novel diagnosis and therapy for HCC and to improve its prognosis. Lactosome is core-shell type polymeric micelle. By enclosing a labeling agent or an anticancer agent in this, it enables drug delivery. In this study, we investigated the diagnostic and therapeutic efficiencies of indocyanine green（ICG）loaded lactosome in near-infrared fluorescence（NIF）imaging and photodynamic therapy（PDT）for HCC.
Results demonstrated that ICG lactosome was accumulated in the tumors in implanted animals and PDT had antineoplastic effects. NIF imaging and PDT with ICG lactosome can be useful as a novel diagnostic and therapeutic agent for HCC.
