Метаболическая навигация с 5‑АЛК – один из методов интраоперационной визуализации в нейроонкологии.</p><p>Цель исследования – провести сравнительный анализ чувствительности метаболической навигации с 5‑АЛК в хирургии первичных и вторичных опухолей головного мозга различной гистологической природы и степени злокачественности.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. За период с 2013 по 2020 г. с использованием метаболической навигации нашей группой прооперировано 403 пациента: микрохирургические резекции выполнены у 384 человек с опухолями головного мозга, из них 220 – с глиальными опухолями, 101 – с интракраниальными менингиомами, 63 – с метастатическим поражением головного мозга. Среди пациентов с метастазами у 39 пациентов отмечалось солитарное поражение, у 16 – многоочаговое, поэтому в данной группе рассмотрено 72 случая метастатических узлов. Стереотаксические биопсии с 5‑АЛК‑ассистенцией выполнены у 19 человек. Метаболическая навигация выполнялась с препаратом 5‑АЛК, который принимали в дозе 20 мг/кг за 2 ч до операции перорально. Интраоперационная флуоресценция оценивалась с помощью микроскопа с флуоресцентным модулем.</p></sec><sec><title>Результаты</title><p>Результаты. Метаболическая навигация с применением микроскопа имеет высокую чувствительность при микрохирургических операциях (в том числе повторных) в случаях анапластических глиом (65 % – в целом, 58 % – яркое свечение), глиобластом (94 % – в целом, 53 % – яркое свечение), интракраниальных менингиом (94 % – в целом, 64 % – яркое свечение). Использование 5‑АЛК имеет существенные ограничения в чувствительности при диффузных глиомах (46 % – в целом, 27 % – яркое свечение) и метастазах в головном мозге (в целом 87 % – для солидной части, 52 % – для ложа, яркое свечение – 51 %). При диффузных глиомах участки свечения имели достоверно более высокий пролиферативный индекс и плотность ядер клеток, чем флуоронегативные зоны. Из важнейших факторов, влияющих на свечение глиом, можно отметить: статус мутации IDH1, объем контрастирующейся части глиомы по данным МРТ, индекс накопления метионина по данным позитронно‑эмиссионной томографии, показатели опухолевого кровотока по данным метода маркирования артериальных спинов – ASL‑перфузии.</p></sec><sec><title>Заключение</title><p>Заключение. Использование 5‑АЛК с применением микроскопа имеет высокую чувствительность при глиобластомах, анапластических глиомах (особенно для выявления неконтрастирующейся части опухоли, которая визуально не изменена в белом свете операционного микроскопа) и менингиомах головного мозга. Метод менее эффективен при глиомах низкой степени злокачественности и интракраниальных метастазах.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Metabolic navigation with 5‑ALA is one of methods for intraoperative imaging in neuro‑oncology.</p></sec><sec><title>Aim</title><p>Aim. To perform a comparative analysis of sensitivity of metabolic navigation with 5‑ALA during surgery of primary and secondary brain tumors of various histological nature and degree of malignancy.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. During the period from 2013 to 2020, our group have performed surgery to 403 patients using metabolic navigation: microsurgical resections were performed in 384 people with brain tumors, 220 of them were with glial tumors, 101 were with intracranial meningiomas, 63 were with metastatic brain damage. Among patients with metastases, 39 patients had a solitary injury, 16 had a multi‑focal injury, so 72 cases of metastatic nodes were considered in this group. Stereotactic biopsies with 5‑ALA‑assistance were performed in 19 people. Metabolic navigation was performed with the drug 5‑ALA, which was taken orally at a dose of 20 mg/kg 2 hours before surgery. Intraoperative fluorescence was evaluated using microscope with a fluorescent module.</p></sec><sec><title>Results</title><p>Results. Metabolic navigation using microscope has a high sensitivity when employed during microsurgery (including repeated implementation of surgery) in cases of anaplastic gliomas (65 % in total, 58 % with bright glow), glioblastomas (94 % in total, 53 % with bright glow), intracranial meningiomas (94 % in total, 64 % – with bright glow). The use of 5‑ALA has significant limitations in sensitivity in cases of diffuse gliomas (46 % – in total, 27 % – with bright glow) and brain metastases (in total 87 % – for the solid part, 52 % – for the bed, with bright glow – 51 %). In diffuse gliomas, the glow areas had significantly higher proliferative index and cell nuclei density than the fluoronegative zones. Among the most important factors affecting the glow of gliomas it can be noted: the status of the IDH1 mutation, the volume of the contrasting part of the glioma according to MRI data, the methionine accumulation index according to positron emission tomography, the tumor blood flow indicators according to the arterial spin marking method – ASL perfusion.</p></sec><sec><title>Conclusions</title><p>Conclusions. Implementation of 5‑ALA navigation with the use of microscope provides high sensitivity in cases of glioblastomas, anaplastic gliomas (especially for detecting of non‑contrasting part of tumor that is not visually altered in the white light of operating microscope) and brain meningiomas. The method is less effective in low‑grade gliomas and intracranial metastases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>метаболическая навигация</kwd><kwd>опухоли головного мозга</kwd><kwd>5‑АЛК</kwd><kwd>протопорфирин</kwd><kwd>флуоресценция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metabolic navigation</kwd><kwd>brain tumors</kwd><kwd>5‑ALA</kwd><kwd>protoporphyrin</kwd><kwd>fluorescence</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (грант № 22-75-10074, Радиомика перифокальной зоны глиом головного мозга: применение диффузионно-куртозисных, релаксационных и перфузионных параметров для определения границ опухолевой инвазии).</funding-statement><funding-statement xml:lang="en">The work was supported by the Russian Science Foundation (grant No. 22-75-10074, Radiomics of the perifocal zone of brain gliomas: application of diffusion-curtosis, relaxation and perfusion parameters to determine the boundaries of tumor invasion).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Потапов А.А., Горяйнов С.А., Охлопков В.А. и др.
