The study objective is to analyze the capabilities of upper respiratory tract fibroscopy for the detection of primary tumor in patients with cervical lymph node metastases from squamous-cell carcinoma without the primary tumor found.</p><p><bold>Materials in methods.</bold> A total of 70 patients with cervical lymph node metastases without the primary tumor found, in whom cytological examination of biopsy specimens collected from cervical lymph nodes revealed squamous-cell carcinoma, underwent upper respiratory tract fibroscopy in N.N. Blokhin National Medical Research Center of Oncology between January 2017 and May 2020.</p><p><bold>Results.</bold> In 24 out of 70 patients, fibroscopy helped to identify the primary tumor and collect biomaterial for morphological examination. Twelve patients were found to have oropharyngeal cancer; ten patients were diagnosed with nasopharyngeal cancer; and 2 patients had laryngopharyngeal cancer. Fifteen out of 24 patients had tumors less than 1.2 cm.</p><p><bold>Conclusion.</bold> Upper respiratory tract fibroscopy is a highly effective method for detecting small asymptomatic tumors. It can be recommended for the examination of patients with metastases from squamous-cell carcinoma without the primary tumor found, if the primary tumor is believed to be located in the upper respiratory tract</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Обнаружение первичного очага при метастазах рака в лимфатических узлах шеи без выявленного первичного очага крайне важно, поскольку локализация первичной опухоли зачастую определяет тактику лечения.</p><p><bold>Цель исследования</bold> – изучить возможности фиброскопии верхних дыхательных путей в выявлении и оценке первичной опухоли при метастазах плоскоклеточного рака в лимфатических узлах шеи без выявленного первичного очага.</p><p><bold>Материалы и методы.</bold> С января 2017 г. по май 2020 г. в Национальном медицинском исследовательском центре онкологии им. Н.Н. Блохина была выполнена фиброскопия верхних дыхательных путей у 70 пациентов с метастазами в лимфатических узлах шеи без выявленного первичного очага, у которых при цитологическом исследовании пунктата лимфатических узлов шеи выявлен плоскоклеточный рак.</p><p><bold>Результаты.</bold> В 24 из 70 случаев фиброскопия позволила обнаружить первичную опухоль и получить материал для морфологического исследования. У 12 больных выявлен рак ротоглотки, у 10 – рак носоглотки, у 2 – рак гортаноглотки. В 15 из 24 случаев размеры опухоли не превышали 1,2 см.</p><p><bold>Заключение.</bold> Как высокоэффективный метод выявления небольших бессимптомных опухолей фиброскопия верхних дыхательных путей рекомендована при обследовании пациентов с метастазами плоскоклеточного рака без выявленного первичного очага, если предполагается локализация первичной опухоли в верхних дыхательных путях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>squamous cell carcinoma</kwd><kwd>metastases without a primary tumor found</kwd><kwd>cervical lymph nodes</kwd><kwd>upper respiratory tract fibroscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>плоскоклеточный рак</kwd><kwd>метастазы без выявленного первичного очага</kwd><kwd>лимфатические узлы шеи</kwd><kwd>фиброскопия верхних дыхательных путей</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">Cancer without detected primary focus.
