title: [Photodynamic therapy of recurrent and residual oropharyngeal and laryngeal tumors].
abstract: Photodynamic therapy (PDT) was given to 61 patients with recurrent cancer of the tongue, oral mucosa, lower lip, oro- and nasopharynx, larynx. Photosensitizers photogem and photosens of Russian produce were employed. The radiation was given twice with the interval 24 and 48 hours, the exposure to light 3 to 30 min. The impact was external, through the instrumental canal of the fibroscope, by intracavitary and interstitial techniques. The response was assessed within 4-6 weeks after the PDT course. The effect was observed in 95.1% patients. Its duration ranged from 4 months to 5 years. Complete resorption of the tumor was achieved in 57.4%. The treatment failed in 4.9% patients.
