Modern, highly selective photo-sensitisers, such as Chlorin E6 or ICG (indocyanine green) and others are available for the treatment of various types of cancer.
Recent research has shown that classical chemotherapy agents also act as photosensitisers and become strongly stimulated by specific wavelengths of light. Thus, low-dose, non-toxic chemotherapy can be used in combination with photodynamic therapy.
Compared with classical chemotherapy, a special advantage lies in the fact that during the follow-up treatment the immune system is not stressed, but strengthened by the intravenous laser therapy. Moreover, the photodynamic therapy itself exerts a secondary immune-boosting effect.
