Paper Abstract

The rationale of photodynamic therapy is based on the cytotoxic action of products generated by excited photosensitizers. Recent development has brought forward a series of promising photosensitizers ranging from hematoporphyrin derivative, various kinds of phthalocyanines and chlorins, to (delta) -aminolevulinic acid. The therapeutic efficacy is dependent on parameters such as tissue oxygenation, sensitizer distribution, drug clearance, optical irradiation, and exposure time. The general outline of a dosimetry model, which enables all these effects to be taken into account, is discussed.
