Paper Abstract

Photophysical reactions have been the focus of laser-tissue interactions. However, these interactions usually have localized and short-term effect, hence only resulting in limited success against systemic lesions, especially against metastatic tumors. Could laser induce a photobiological reaction, specifically a long-term reaction in cancer treatment. Our experimental results on treatment of rat breast cancer indicated that a systemic and long term response against the tumors could be stimulated by a new laser-sensitizer-immunoadjuvant treatment. Long term impact of our method was observed; survival tumor rats and apparent ability against tumor re-challenge. The long term effect was also confirmed by our histochemical studies. Our results pointed to a humoral immune response. A new mechanism of laser-tissue interaction, namely laser-sensitizer- immunoadjuvant induced photobiological reaction, may prove to be crucial in laser cancer treatment.
