Probability of development of multiple primary tumors in patients who received treatment due to head and neck cancers varies between 5.6 and 35.9 % per different sources. moreover, treatment capabilities are severely limited by postoperative anatomical changes and previous radiation therapy, and the second tumor frequently causes death in these patients.</p><p><bold>The study objective</bold> is to identify the epidemiological features of the development of synchronous and metachronous primary multiple tumors in the head and neck.</p><p><bold>Materials and methods</bold>. The article analyzes data on 103 patients with multiple primary tumors who received treatment due to tumors of the head and neck between 1991 and 2020 at the N.N. Blokhin National medical Research Center of Oncology and A.S. Loginov Moscow Clinical Scientific Center.</p><p><bold>Results</bold>. During the study, typical locations of metachronous tumors in patients who received treatment due to primary malignant tumors of the head and neck were determined, duration of development of multiple primary tumors, treatment methods and survival rates were analyzed.</p><p><bold>Conclusion</bold>. Due to high risk of multiple primary tumors in patients who received treatment due to malignant tumors of the head and neck in the next 5 plus years, it is expedient to observe these patients during their whole lifetime. Considering typical locations of metachronous tumors, examination during dynamic observation should include instrumental methods such as panendoscopy. Surgical treatment should involve the whole spectrum of minimally invasive interventions including CO<sub>2</sub> laser surgery and transoral robot-assisted interventions.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Вероятность развития первично-множественных опухолей у пациентов, получавших лечение по поводу злокачественных опухолей головы и шеи, составляет, по разным источникам, от 5,6 до 35,9 %. при этом возможности лечения резко ограничиваются как послеоперационными изменениями анатомии, так и последствиями проведенной лучевой терапии, в связи с чем вторая опухоль зачастую является причиной смерти таких больных.</p><p><bold>Цель исследования</bold> - выявление эпидемиологических особенностей развития синхронных и метахронных первично-множественных опухолей в области головы и шеи.</p><p><bold>Материалы и методы</bold>. Проанализированы данные 103 пациентов с первично-множественными опухолями, получавших лечение по поводу опухолей головы и шеи в период с 1991 по 2020 г. на клинической базе Национального медицинского исследовательского центра онкологии им. Н.Н. Блохина Минздрава России и московского клинического научного центра им. А.С. Логинова Департамента здравоохранения г. Москвы.</p><p><bold>Результаты</bold>. В ходе исследования определены типичные локализации метахронных опухолей у пациентов, первично получавших лечение по поводу злокачественных новообразований головы и шеи, проанализированы сроки возникновения первично-множественных опухолей, методы их лечения и показатели выживаемости.</p><p><bold>Заключение</bold>. В связи с высоким риском возникновения первично-множественных опухолей у пациентов, получивших лечение по поводу злокачественных новообразований головы и шеи в сроки, превышающие 5 лет, целесообразно продолжать их динамическое наблюдение в течение всей жизни. с учетом типичных локализаций метахронных опухолей в комплекс обследований при динамическом наблюдении следует включать инструментальные методы, такие как панэндоскопия. при хирургическом лечении необходимо использовать весь спектр малоинвазивных вмешательств, в том числе СO<sub>2</sub>-лазерную хирургию и трансоральные робот-ассистированные вмешательства.</p></trans-abstract><kwd-group xml:lang="en"><kwd>squamous cell carcinoma</kwd><kwd>head and neck tumors</kwd><kwd>multiple primary tumors</kwd><kwd>reconstructive surgery</kwd><kwd>СO<sub>2</sub> laser surgery</kwd><kwd>transoral surgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>плоскоклеточный рак</kwd><kwd>опухоли головы и шеи</kwd><kwd>первично-множественные опухоли</kwd><kwd>реконструктивная хирургия</kwd><kwd>СO<sub>2</sub>-лазерная хирургия</kwd><kwd>трансоральная хирургия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Gonzalez-Garda R., Naval-G^as L., Roman-Romero L. et al.
