Поиск литературных источников в базах данных Pubmed, EMBASE и eLibrary продемонстрировал отсутствие исследований, посвященных изучению особенностей и факторов риска рецидивирования интрадуральных опухолей спинного мозга. Цель исследования – выявить особенности и факторы риска рецидивирования интрадуральных опухолей спинного мозга после выполнения микронейрохирургической резекции. материал и методы. В исследование включены медицинские карты 196 пациентов с интрадуральными экстрамедуллярными и интрамедуллярными опухолями спинного мозга. Проанализированы объем микронейрохирургической резекции опухолевой ткани, клиническая эффективность выполненных оперативных вмешательств, факторы риска и особенности рецидивирования интрадуральных спинальных неоплазий. Результаты. Снижение степени неврологического дефицита после оперативного вмешательства отмечено в 116 (59,1 %) случаях, у 47 (24,0 %) пациентов неврологический статус остался прежним и у 33 (16,8 %) больных отмечено ухудшение степени неврологического дефицита. Тотальная микронейрохирургическая резекция интрадуральных опухолей спинного мозга достигнута у 140 (71,4 %) пациентов, субтотальная резекция – в 22 (11,2 %) случаях, частичная резекция – у 25 (12,7 %) пациентов, и биопсия или декомпрессия спинного мозга и/или его корешков выполнена 9 (4,6 %) больным. Вероятность безрецидивной выживаемости пациентов с доброкачественными интрадуральными опухолями спинного мозга значимо превышала такой показатель у больных со злокачественными новообразованиями (p&lt;0,001). Доброкачественные опухоли (χ2=34,7, p&lt;0,05), неоплазии грудной и пояснично-крестцовой локализации (χ2=10,3, p&lt;0,05), низкая степень неврологического дефицита (χ2=31,5, p&lt;0,05), отсутствие признаков сирингомиелии/сирингобульбии (χ2=13,2, p&lt;0,05), а также экстрамедуллярная локализация (χ2=12,6, p&lt;0,05) значимо позволяют достигнуть тотальной микронейрохирургической резекции. Злокачественные опухоли (χ2=34,8, p&lt;0,05), шейная и грудная локализация (χ2=8,4, p&lt;0,05), высокая степень неврологического дефицита (χ2=12,9, p&lt;0,05), выполнение частичной резекции, биопсии или декомпрессии невральных структур (χ2=9,7, p&lt;0,05), интрамедуллярная локализация опухолей значимо повышают риск рецидива. заключение. Гистологические особенности, локализация, степень предоперационного клинико-неврологического дефицита по шкале McCormick и объем оперативного вмешательства являются достоверными факторами риска рецидивирования интрадуральных опухолей спинного мозга.</p></abstract><trans-abstract xml:lang="en"><p>Spinal cord tumors include a variety of nosological units and are classified according to their localization and histological type. The search for literature sources in the Pubmed, EMBASE and eLibrary databases demonstrated the absence of studies devoted to study of the features and risk factors for the recurrence of intradural spinal tumors. the purpose of this study was to reveal features and risk factors of recurrence of intradural spinal tumors after microneurosurgical resection. material and methods. The study included medical records of 196 patients with intradural extramedullary and intramedullary spinal tumors. The extent of microneurosurgical tumor resection, clinical efficacy of surgery, and risk factors for recurrence of intradural spinal cord tumors were been analyzed. results. Improvement in neurologic deficit after surgery was noted in 116 (59.1 %) cases, neurologic status remained the same in 47 (24.0 %) patients, and worsening of neurological deficit was observed in 33 (16.8 %) cases. Total microneurosurgical resection of intradural spinal tumors was performed in 140 (71.4 %) patients, subtotal resection in 22 (11.2 %) patients, partial resection in 25 (12.7 %) patients and spinal cord decompression or biopsy and/or its roots were performed in 9 (4.6 %) of patients. The likelihood of recurrence-free survival of patients with benign intradural spinal cord tumors was significantly higher than that of patients with malignant tumors (p&lt;0.001). Benign tumors (χ2=34.7, p&lt;0.05), thoracic and lumbosacral tumors (χ2=10.3, p&lt;0.05), low degree of neurological deficit (χ2=31.5, p&lt;0.05), absence of syringomyelia/syringobulbia signs (χ2=13,2, p&lt;0,05), as well as extramedullary tumors (χ2=12,6, p&lt;0.05) allowed us to perform total degree microneurosurgical resection. Malignant tumors (χ2=34.8, p&lt;0.05), cervical and thoracic tumors (χ2=8,4, p&lt;0,05), high degree of neurological deficit (χ2=12,9, p&lt;0.05), partial resection, biopsy or decompression of neural structures (χ2=9.7, p&lt;0.05) and intramedullary tumors statistically significantly increased the risk of their recurrence. conclusion. Histological pattern, tumor localization, preoperative clinical and neurological deficit according to the McCormick classification and the extent of surgery are significant risk factors for recurrence of intradural spinal tumors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интрадуральные опухоли спинного мозга</kwd><kwd>микронейрохирургическая резекция</kwd><kwd>рецидивирование</kwd><kwd>факторы риска</kwd><kwd>клинико-морфологические особенности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intradural spinal tumors</kwd><kwd>microneurosurgical resection</kwd><kwd>recurrence</kwd><kwd>risk factors</kwd><kwd>clinical and morphological features</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bhat A.R., Kirmani A.R., Wani M.A., Bhat M.H.
