Abstract

We made an experimental and clinical researches to examine Intraoperative Photodynamic Therapy (IPT) as a method to prevent the recidives of tumors. In experimental researches on models with radio-inducated fibrosarcomas and Erlich carcinomas of mice the best method of IPT was worked out. The therapeutic effect was studied also on patients with laryngeal cancer. In researches on C3H mice the antirecidive effect of IPT established with local administration of methylene blue and Ar-laser. We found that IPT (He-Ne laser combined with methylene blue administration) was endured by patients with laryngeal cancers without problems. We got good results of treatment 42 patients with laryngeal cancers with middle localization during three years with using IPT method. This can show the perspectives of using this method in treatment of other ENT-oncological diseases.
