| Outline of Final Research Achievements |
The effect of Photodynamic therapy can be expected as an adjunct therapy for unresectable cholangiocellular carcinoma. On the other hand, there are side effects such as ray hypersensitivity. Accordingly, the development of a new photosensitizer of high anti-cancer effects and high tumor specificity is expected. We compared the effects of photodynamic therapy for bile duct carcinoma using glucose-conjugated chlorine(G-PDT), which is expected as a new photosensitizer and talaporfin sodium(L-PDT), which is a photosensitizer that is currentry used.
In experiments with cells, apoptotic induction rate in the G-PDT showed more increased rate in comparison with that in the L-PDT. Cytocidal effect in the G-PDT was higher than in the L-PDT. In animal experiments, A treatment of the new G-PDT showed the high inhibition of tumor growth in the treatment of bile duct carcinoma cells.
