Outline of Final Research Achievements |
We hypothesized that the combination of the existence of photo enhancer and low dose laser irradiation can heat the target tumor selectively to kill the cancer. Systemically administrated porphysomes nano-particles accumulate in lung cancer at higher level than that of normal tissue and absorb red light energy to heat the tumor. Locally injected Indocyanine green also absorb the infra-red light energy to heat the tumor. Using lung cancer animal models, we confirmed the cytotoxic effect of the combination therapy of photo-enhancer administration and low power laser irradiation. Reflect on the promising results of the current study, we are preparing for the clinical study in the next step.
