Hematoporphyrin (Photodyn), a porphyrin prepared from hemin, is used as a photosensitizer in photodynamic therapy. Photodynamic therapy is based on the use of light-sensitive photosensitizers. Photoactivation causes the formation of singlet oxygen, which produces peroxidative reactions that can cause cell damage and death. Hematoporphyrin was used as the therapeutic agent in patients with manic-depressive reactions and in patients with involutional melancholia. One of the last studies has shown, that Hematoporphyrin-Photodynamic therapy (PDT) combined with stent placement is an effective and safe treatment for extrahepatic cholangiocarcinoma (EHCC).
