Первичные опухоли центральной нервной системы составляют около 2 % от всех опухолей человека. Удаление опухоли, как правило, – необходимый этап лечения. Основная задача хирургии внутримозговых опухолей – максимальнo радикальное удаление образoвания в пределах физиологически дозволенных границ, что напрямую влияет на качество и продолжительность жизни больных.</p><p>Цель исследования – оценить результаты хирургического лечения опухолей моторных зон и выявить предикторы развития необратимых двигательных нарушений.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Ретроспективно проанализированы результаты хирургического лечения 105 пациентов с опухолями, поражающими кортикоспинальный тракт и первичную моторную кору головного мозга или находящимися в непосредственной близости от них (на расстоянии до 10 мм). Все больные пролечены в нейрохирургическом отделении ФГБУ «Национальный медико‑хирургический центр им. Н. И. Пирогова» Минздрава России (Москва) в период с 2014 по 2020 г. Мужчин – 48 (46 %), женщин – 57 (54 %). Возраст пациентов – от 22 до 79 (средний возраст 47,6 ± 14,5) лет. Объем опухоли до операции варьировал в пределах от 5,16 до 283,3 (средний объем 80,9 ± 55,1) см3. Размеры и взаимоотношение опухолей с окружающими структурами оценивали по данным предоперационной магнитно‑резонансной томографии и магнитно‑резонансной трактографии. Для интраоперационной оценки динамики состояния моторных зон использовали транскраниальную электростимуляцию (n = 105, 100 %), прямую транскортикальную стимуляцию первичной моторной коры мозга с применением 8‑контактного электрода‑полоски (n = 68, 64,8 %). Близость расположения моторных зон оценивали с помощью прямой кортикальной и субкортикальной би‑ и монополярной электростимуляции (n = 105, 100 %).</p></sec><sec><title>Результаты</title><p>Результаты. Тотально удалены 67 (63,8 %) опухолей, близко к тотальному – 22 (20,9 %), субтотально – 11 (10,5 %), частично – 5 (4,8 %). После операции объем опухоли варьировал от 0 до 84,4 (средний объем 3,54 ± 5,01) см3. Через 24 ч развитие нового или нарастание имевшегося до операции двигательного дефицита выявлено у 46 (43,8 %) пациентов, через 7 дней – у 32 (30,5 %). Однако на фоне консервативной терапии дефицит регрессировал у большинства пациентов и при осмотре через 6 мес сохранялся только у 12 (11,4 %) пациентов. При оценке факторов, влияющих на развитие стойкого двигательного дефицита, получена статистически значимая связь с интраоперационным снижением амплитуды ответа по данным транскраниальной стимуляции (p &lt; 0,001), а также транскортикальной стимуляции (p &lt; 0,001). Не отмечено значимых изменений в функциональном статусе пациентов в послеоперационном периоде в зависимости от силы стимула прямой стимуляции, на которой была остановлена резекция (р = 0,9), а также от радикальности удаления опухоли (p = 0,393).</p></sec><sec><title>Выводы</title><p>Выводы:</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Primary tumors of central nervous system account for about 2 % of all human tumors. Generally, the tumor removal is a necessary treatment step. The main goal of the intracerebral tumors surgical treatment is the formation removal in the most radical physiologically possible way, because this directly affects the patients’ life length and its quality.</p></sec><sec><title>Aim</title><p>Aim. To assess the results of surgical treatment of motor zone tumors and identify predictors of development of irreversible motor disorders.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective analysis of results of surgical treatment from 105 patients with tumors that affect corticospinal tract and primary motor cortex of the brain or localized in close proximity to those areas (up to 10 mm). All patients were treated in the neurosurgical department of N.I. Pirogov National Medical and Surgical Center, Ministry of Health of Russia (Moscow) in the period from 2014 to 2020. There were 48 (46 %) men, 57 (54 %) women aged from 22 to 79 (mean age 47.6 ± 14.5) years. Tumors volume before surgery ranged from 5.16 to 283.3 (mean volume 80.9 ± 55.1) cm3. The tumors’ size and their relationship with the surrounding structures were assessed by pre‑surgery magnetic resonance imaging and magnetic resonance tractography. For the intraoperative assessment of motor zone state dynamics, the transcranial electrical stimulation (n = 105, 100 %) and direct transcortical stimulation (with the eight‑contact electrode stripe) (n = 68, 64.8 %) of the primary motor cortex were used. To assess the proximity of the motor zones, a straight cortical and subcortical bi‑ or monopolar electrical stimulation was used (n = 105, 100 %).</p></sec><sec><title>Results</title><p>Results. Sixty‑seven tumors (63.8 %) were removed completely, close to total removal was in 22 (20.9 %) tumors, 11 (10.5 %) tumors removal was subtotal and 5 (4.8 %) tumors were removed partially. Tumor volume after surgery ranged from 0 to 84.4 (mean volume – 3.54 ± 5.01) cm3, Development of novel motor deficiency or increase in pre‑surgery motor deficiency was observed in 46 (43.8 %) patients 24 hours after surgery and in 32 (30.5 %) of them 7 days after the treatment. However, during course of conservative therapy, the majority of patients showed regress of motor deficit and it remained only in 12 (11.4 %) patients on examination that was performed 6 months after surgery. Assessment of factors affecting development of persistent motor deficiency revealed its statistically significant association with intraoperative response decrease according to transcranial stimulation (p &lt; 0.001) and transcortical stimulation (p &lt; 0.001) data. There were no significant changes in the functional status of patients during postoperative period depending on strength of the direct stimulation when the resection was stopped (р = 0.9) or depending on radicality of tumor removal (p = 0.393).</p></sec><sec><title>Conclusion</title><p>Conclusion.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>опухоли головного мозга</kwd><kwd>глиомы</kwd><kwd>нейрофизиологический мониторинг</kwd><kwd>опухоли моторных зон</kwd><kwd>кортикоспинальный тракт</kwd></kwd-group><kwd-group xml:lang="en"><kwd>brain tumors</kwd><kwd>gliomas</kwd><kwd>neurophysiological monitoring</kwd><kwd>motor zones tumors</kwd><kwd>corticospinal tract</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">Ostrom Q.T., Patil N., Cioffi G. et al.
