Photodynamic therapy in the treatment of stomach cancer

Abstract

The analysis of the results of treatment of 10 patients with gastric cancer with high surgical risk, who in the treatment complex used photodynamic therapy with photosensitizer Photolon and further irradiation with a semiconductor laser with a wavelength of λ = 0.67 μm cross-irradiation fields introduced through the biopsy channel of the endoscope. Endoscopic PDT can be used at the stage of combined treatment in combination with drug therapy and surgical interventions and is an effective means of preventing the development of esopha- geal-small intestinal anastomosis failures in the early postoperative period. Endoscopic PDT can also be used in the postoperative period as a prophylaxis of early postoperative complications in cases of detection of tumor cells in the margins of resection.
