Photoditazine mediated chemosensitized blood photomodification: advanced tumor treatment preliminary results

Abstract

Beside the classical photodynamic therapy (PDT) procedure, another possible mode of PDT treatment exists. In the latter case the light does not have to be delivered directly to tumor as soon as it is not always technically possible. In some cases systemic cytotoxic effects of photomodified blood can cause tumor damage. Possibly this happens due to apoptosis induction. These observations broaden possible PDT applications significantly.
