Basing on their experience with sparing surgery in combined treatment of pharyngeal carcinoma, the authors have developed a method for specification of the diagnosis before treatment and in the course of surgical intervention. Preoperative gamma-beam therapeutic scheme has been improved: long-distance irradiation is carried out under hyperbaric oxygenation with medium-fractionated doses and the total dose is reduced to 23.1 Gy, the intervals between the irradiation and surgery being 7-10 days. In order to improve the functional efficacy of economic radical surgery, methods of sparing surgery for Stages III-IV pharyngeal carcinoma were developed. Favorable functional and 3-year results were achieved in 314 patients with pharyngeal carcinoma, treated according to a multiple-modality scheme, including economic surgery as its second stage.
