Blokhin National Medical Research Center of Oncology.</p><p><bold>Materials and methods</bold>. We analyzed the data of 115 ENB patients who had undergone treatment between 1965 and 2019.</p><p><bold>Results</bold>. The 15-year overall survival rate was 1.2–1.7 times higher in patients receiving comprehensive treatment (47.7 ± 11.3 %) than in those receiving other types of therapy. In addition to that, comprehensive treatment ensured the highest rates of 3-year, 5-year, and 10-year relapse-free survival (49.3 ± 11.8 %), as well as the longest median survival (7.2 years). Chemoradiotherapy was effective in 34.8 % of patients with locally advanced ENB, while in 9 out of 45 patients (20.0 %), it resulted in partial response, which suggest that such treatment can control aggressive disease course and increase survival. Surgical treatment (alone or in combination with chemotherapy and radiotherapy) was indicated for 64 patients. However, only in 43 of them (67.1 %), it was performed as originally planned. Five patients (7.8 %) had partially radical surgeries and sixteen patients (25.1 %) had non-radical surgeries.</p><p><bold>Conclusion</bold>. The most effective treatment strategy for locally advanced ENB is a combination of surgery, chemotherapy, and radiotherapy. Chemoradiotherapy at the first stage followed by surgery was found to be an optimal treatment scheme. Tumor sensitivity to chemo- and radiotherapy affects both short-term and long-term treatment outcomes. Partially radical surgeries for locally advanced ENB are acceptable if conservative treatment is planned after operation. Treatment strategy should depend on the tumor spread (stage), grade, and proliferative activity, as well as patient’s age, somatic status, and comorbidities. Multivariate analysis has demonstrated that none of treatment methods decrease survival. The most significant factors negatively affecting the prognosis were as follows: T3–4 tumor, involvement of regional lymph nodes before treatment initiation, distant metastasis, grade IV tumor, and Ki-67 index &gt;21 %.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – обобщить клинический опыт лечения эстезионейробластомы (ЭНБ), накопленный в Национальном медицинском исследовательском центре онкологии им. Н.Н. Блохина.</p><p><bold>Материалы и методы</bold>. Проанализированы данные 115 пациентов с ЭНБ, которые прошли лечение в период с 1965 по 2019 г.</p><p><bold>Результаты</bold>. Общая 15-летняя выживаемость в 1,2–1,7 раза выше при комплексном лечении (47,7 ± 11,3 %), чем при других его вариантах. Уровень 3-, 5-, 10- летней безрецидивной выживаемости (49,3 ± 11,8 %) и медиана выживаемости (7,2 года) при использовании комплексного метода являются наиболее высокими. Химиолучевая терапия оказалась эффективной у 34,8 % пациентов с местно-распространенной ЭНБ, а у 9 (20,0 %) из 45 пациентов привела к частичному регрессу, что свидетельствует о возможности сдерживания агрессивного течения опухоли и увеличения продолжительности жизни. Хирургические операции, назначенные 64 пациентам как самостоятельное лечение и в комбинации с химио- и лучевой терапией, удалось выполнить в запланированном объеме у 43 (67,1 %) из 64 пациентов, условно-радикальные операции проведены у 5 (7,8 %) из 64, нерадикальные операции – у 16 (25,1 %).</p><p><bold>Заключение</bold>. Наиболее эффективной тактикой лечения местно-распространенной ЭНБ является комбинация хирургического, лучевого, химиотерапевтического методов. Оптимальным представляется проведение химиолучевой терапии на 1-м этапе и операции на 2-м этапе лечения. Чувствительность опухоли к химио- и лучевой терапии влияет на непосредственные и отдаленные результаты лечения. При планировании консервативного лечения после хирургического являются оправданными условно-радикальные хирургические вмешательства при местно-распространенных ЭНБ. Тактика лечения определяется распространенностью поражения (стадией), злокачественностью, пролиферативной активностью опухоли, возрастом и соматическим состоянием пациента, наличием сопутствующих патологий. Многофакторный анализ показал, что все методы лечения не ухудшают прогноз жизни пациента. Наиболее значимыми факторами, ухудшающими прогноз лечения, оказались распространенность опухолевого процесса T3–4, поражение регионарных лимфатических узлов до начала лечения, отдаленное метастазирование, IV степень злокачественности, индекс Ki-67 &gt;21 %.</p></trans-abstract><kwd-group xml:lang="en"><kwd>esthesioneuroblastoma</kwd><kwd>nasal cavity</kwd><kwd>treatment methods</kwd><kwd>efficacy</kwd><kwd>survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эстезионейробластома</kwd><kwd>полость носа</kwd><kwd>методы лечения</kwd><kwd>эффективность</kwd><kwd>продолжительность жизни</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">Shtil A.A., Korolev V.A., Zaitsev V.B.
