Intraoperative Monitoring of Photodynamic Therapy Efficacy using Diffuse Optical Spectroscopy in Mesotheloma Patients: Focusing on the Effect of PDT-induced Hypoxia

We used Diffuse Optical Spectroscopy to measure the effect of PDT on hemoglobin concentration changes during intra-operative PDT for mesothelioma. Those with less PDT-created hypoxia had better prognosis than those with severe hypoxia.
