Paper Abstract

The analysis of the results of photodynamic therapy (PDT) for treating malignant neoplasms of skin, breasts, tongue, oral mucose, lower lip, larynx, stomach, bladder, rectum and other locations has been made. During 1992 - 1996 867 tumoral foci in 222 patients have been treated with PDT. All patients were previously treated with conventional techniques or they were not treated due to contraindications either because of severe accompanying diseases or because of old age. A part of the patients had PDT because of recurrences or intradermal metastases in 1 - 2 years after surgical, radial or combined treatment. Up to now we have follow-up control data within 2 months and 4 years. Positive effect of PDT was seen in 93.7% of patients including complete regression of tumors in 64.9% and partial in 28.8%. Currently this new perspective technique of treating malignant neoplasms is successfully being used in Russia; new photosensitizers and light sources for PDT and fluorescent tumor diagnostics are being developed as well.
