[TREATMENT AND PREVENTION OF METASTASIS TO THE PRE- AND PARATRACHEAL LYMPH NODES IN CANCER OF THE LARYNX WITH SPREAD TO THE SUBGLOTTIC SECTION].

Based on the specificity of the subglottic cancer, the basic method of treatment is surgical, because many years of experience have shown the ineffectiveness of chemotherapy and the low effectiveness of radiation therapy. We have developed and introduced in practice the method of extended-combined laryngectomy is effective not only in terms of treating the underlying disease, but also for preventive purposes, reducing the risk of metastases in pre- and paratracheal lymphatic zones. The method of extended-combined laryngectomy includes mobilization of the larynx and its removal at level V or VI of the tracheal rings, lymph node dissection at level VI, both on the affected side and prophylactically from the opposite side, as well as removal of either the thyroid gland on the side of the lesion subglottic cancer, or at its circulatory location total removal of the gland.

[EVALUATION OF THE EFFICACY OF THE EXTENDED-COMBINED OPERATIONS ON THE ZONES OF PRE- AND PARATRACHEAL METASTASIS IN SUBGLOTTIC CANCER OF THE LARYNX].

After a retrospective study of the history of patients with a diagnosis of laryngeal cancer (2151 people), as well as the analysis of their own clinical materials, subglottic cancer was found in 103 patients, which was 4.8% of the total number of patients admitted to the hospital. One group of patients (n=39) underwent laryngectomy with subsequent irradiation, another group (n=64) was carried out by us developed and introduced into practice the method of the extended-combined laryngectomy.
