Степень резекции опухоли (СРО) является доказанным прогностическим фактором выживаемости пациентов с ГВЗ. Поиск литературных источников в базах данных Pubmed, Medline и e-Library показал отсутствие исследований по применению флуоресцентной навигации с 5-аминолевулиновой кислотой (ФН-5-АЛК) в хирургии ГВЗ, основанных на сопоставлении нейровизуализационных, интраоперационных параметров и клинических данных. Цель исследования – провести анализ результатов применения ФН-5-АЛК в хирургии ГВЗ путем изучения и сопоставления нейровизуализационных характеристик, интраоперационных параметров и клинических результатов. Материал и методы. В исследование включены 48 пациентов (30 мужчин, 18 женщин) в возрасте от 35 до 76 лет (средний возраст – 47,3 ± 8,4 года), прооперированных по поводу впервые диагностированных ГВЗ головного мозга. Определены значения СРО, особенности интраоперационной флуоресценции различных типов ГВЗ и возможность определения границ опухоли с прилежащим веществом головного мозга при использовании ФН-5-АЛК, а также изучены показатели функционального статуса пациентов по индексу Карновского. Результаты. Анализ СРО показал, что в 40 (83,3 %) случаях впервые диагностированных ГВЗ удалось достигнуть максимальной СРО (90–98 %). Максимальная СРО выполнена у 28 (58,3 %) пациентов с глиобластомами и у 12 (25 %) пациентов с глиомами III степени злокачественности (p=0,408). Кроме того, максимальная СРО достигнута при микронейрохирургическом удалении 9 (18,75 %) ГВЗ, имеющих объем ≥9 см3 , и 21 (43,75 %) ГВЗ объемом&lt; 9 см3 (р=0,029). При сопоставлении данных ФН-5-АЛК и интраоперационной нейронавигации у 28 (58,3 %) пациентов границы опухолевой ткани не совпадали. Расхождения в полученных данных относительно границ опухолей отмечены у 19 (39,5 %) пациентов с глиобластомами и в 3 (6,25 %) случаях глиом III степени злокачественности (p=0,014), а также в 9 (18,75 %) случаях ГВЗ объемом ≥9 см3 и в 14 (29,1 %) случаях ГВЗ, имеющих объем&lt; 9 см3 (p=0,677). Оценка функционального статуса пациентов до и после оперативного вмешательства показала следующие результаты: у 36 (75 %) пациентов отмечено улучшение функционального статуса по индексу Карновского, в 9 (18,75 %) случаях статус остался на прежнем уровне и у 3 (6,25 %) пациентов отмечено ухудшение функционального статуса. Заключение. Применение ФН-5-АЛК при микронейрохирургической резекции ГВЗ различных локализаций позволяет в большинстве случаев достигнуть тотальной СРО. Размеры ГВЗ и локализация являются важнейшими факторами в достижении максимальной СРО.</p></abstract><trans-abstract xml:lang="en"><p>High grade gliomas (HGG) are the most aggressive primary brain tumors. The extent of resection (EOR) is proved to be an important prognostic factor in patients with HGG. There are no yet published studies on the use of fluorescent-guided resection using 5-aminolevulinic acid (5-ALA) in HGG surgery, based on the comparison of neuroimaging characteristics, intraoperative parameters and clinical outcomes. The purpose of this study was to analyze the results of 5-ALA fluorescent-guided resection in patients with HGG by comparing neuroimaging characteristics, intraoperative parameters and clinical outcomes. Material and methods. The study included 48 patients (30 men and 18 women) aged 35 to 76 years (mean age 47.3 ± 8.4 years) with newly diagnosed HGG. The patients underwent fluorescent-guided surgery that permitted the intraoperative visualization of malignant glioma tissue and supported the neurosurgeon with real-time guidance for differentiating tumor from normal brain. The Karnofsky performance status (KPS) was assessed. Results. The maximum EOR (90–98 %) was achieved in 40 (83.3 %) patients with newly diagnosed HGG. The maximum EOR was performed in 28 (58.3 %) patients with glioblastomas and in 12 (25 %) patients with grade III gliomas (p=0.408) In addition, the maximum EOR was achieved by microneurosurgical removal of 9 (18.75 %) HGGs having a volume of ≥9 cm3 and 21 (43.75 %) of HGGs with a volume&lt;9 cm3 (p=0.029). The tumor boundaries detected by neuronavigation differed by fluorescence data in 28 (58.3 %) patients The divergence between neuronavigation and 5-ALA fluorescence was reported in 19 (39.5 %) patients with glioblastomas and in 3 (6.25 %) patients with grade III gliomas (p=0.014); and in 9 (39.5 %) and in 14 (29.1 %) patients affected with larger (≥9 cm3 ) and smaller (&lt;9 cm3 ) tumor, respectively (p=0.677). Overall, 36 (75 %) patients experienced an improvement in their KPS score, 9 (18.75 %) remained stable, and 3 (6.25 %) declined. Conclusion. The use of 5-ALA fluorescence in surgery for HGG makes it possible to achieve the gross total resection in most cases. The localization of HGGs and their size are the most important factors in achieving maximum EOR.

Overall, 36 (75 %) patients experienced an improvement in their KPS score, 9 (18.75 %) remained stable, and 3 (6.25 %) declined. Conclusion.
