Multiple laser irradiation of ORL organ tumors in photodynamic therapy

摘要

The results of ORL organ tumor photodynamic therapy with the use of Phtalocyanine Al and multiple sequences of laser irradiation are presented. The possibility of decreasing the concentration of the preparation in accordance with laser irradiation tactics was investigated. The process of tissue necrotization for big and difficult tumors for laser irradiation access has been investigated. The estimation of photosensitizer distribution character for local injection has been carried out. The principal possibility of using local injection of photosensitizer for photodynamic therapy has been shown.
