Paper Abstract

The visible light, which is used for the activation of photosensibilizator, penetrates the tissue approximately only 2 cm. If the tumor is large, PDT alone is only the palliative method of treatment. Nd:YAG laser evaporation of big size tumors together with PDT let us provide the radical treatment. Since 1989 to 1996 there were 119 patients with 172 tumors of head and neck treated with PDT. The size of the tumor varied from 0.2 cm2 to 6 cm2. The thickness of the tumor varied from 0.1 to 1.5 cm. There were 30 patients with 82 large head and neck tumors with the ones settled in the location difficult to reach too. Nd:YAG laser (30 - 40 W) was used in order to remove the tumors mass. After 2 - 4 days passed, the PDT treatment was provided for all these 30 patients. The immediate result of Nd:YAG laser evaporation of large tumors together with PDT was the same as in usual usage PDT, when PDT was provided for considerably smaller tumors.
