Abstract. Photodynamic therapy (PDT) is a promising method for the treatment of tumors with a broad potential of clinical and research applications. However, there remain issues that need to be clarified. Among them are photosensitizer (PS) biodistribution in the tumor, photodynamic reactions which occur in human tumors, and morphological responses. Studying of the morphological response of human skin tumours after PDT with Chlorine E-6 photosensitizers is necessary for understanding mechanisms of PDT and developing new treatment strategies.
Key words: photodynamic therapy (PDT), Chlorine E-6 photosensitizers, morphological changes, vascular mechanisms of PDT.
