В исследуемую группу вошло 78 пациентов, из них с диагнозом анапластическая астроцитома (АА) 48 (61,5%) пациентов и анапластическая олигодендроглиома (АОД) 30 (38,5%) пациентов; во всех случаях супратенториальной локализации. Всем пациентам выполнена ПЭТ-КТ с 11С-метионином по стандартной методике, а также МРТ в режимах Т1, Т2, Т2-FLAIR, DWI и 3D Т1+Gd. В 71 случае выполнено удаление опухоли, в 8 – верификация гистологического диагноза путем стереотаксической биопсии. Все опухоли подверглись молекулярно-генетическому анализу, в том числе с исследованием мутации IDH1 и ко-делеции 1p/19q.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. Метаболический объем опухоли и величина ИН РФП были статистически значимо выше в группе IDH-негативных АА, нежели в группе IDH-позитивных АА; кроме того, АА дикого типа продемонстрировали более высокие значения долевого накопления РФП. Наименьший общий объем опухоли по МРТ продемонстрировали АОД, при этом долевой объем контрастирования этих опухолей был значительно выше, чем в общей группе астроцитарных опухолей; для АОД характерно минимальное отличие общего объема опухоли от метаболического. Значения ИН РФП уменьшается в ряду АА IDH− – АОД – AA IDH+, однако эти различия не достигли статистически значимых величин. В группе IDH-негативных АА объем метаболически активной ткани по данным ПЭТ демонстрировал слабоотрицательную зависимость с общей и безрецидивной выживаемостью, а объем опухоли в группе IDH-мутантных АА коррелировад только с безрецидивной выживаемостью.</p></sec><sec><title>Заключение</title><p>Заключение. Настоящая работа на крупнейшем клиническом материале анализирует соотношения результатов МРТ и ПЭТ-КТ с 11С-метионином в группе глиом Grade III. На основании полученных данных удалось продемонстрировать неоднозначность зависимости значений ИН РФП в группе анапластических глиом от наличия олигодендрокомпонента в гистоструктуре опухоли, где, в отличие от глиом Grade II, не получено значимых отличий в уровне метаболической активности астроцитарных и олигодендроглиом, обе группы демонстрировали большой разброс показателей.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of this study was to evaluate average 11C-methionine uptake for grade II (anaplastic) gliomas in a large cohort, as well as relations between MRI and PET characteristics and their unfluence on overall and progression-free survival.</p><sec><title>Materials and methods</title><p>Materials and methods. The study was based upon 78 patients with supratentorial tumors, among them 48 with anaplastic astrocytoma (AA) and 30 with anaplastic oligodendroglioma (AO). ALL patients underwent PET-CT with 11C-methionine and MRI study (Т1, Т2, Т2-FLAIR, DWI и 3D Т1+Gd regimes). Tumor removal was performed in 71 cases, stereotactic biopsy in 8 patients. Tumor specimen were assessed by neuropatomorphologists and IDH1-status and 1p/19q co-deletion were evaluated.</p></sec><sec><title>Study results</title><p>Study results. AA IDH− tumors demonstrated statistically significant bigger metabolic volume and radiotracer uptake comparing with AA IDH+. Moreover, AA IDH − characterized by higher fractional MET uptake. The smallest tumors (by MRI) were AOs, meanwhile their fractional contrast enhancement was higher than for AAs. AOs were also known as tumors with minimal difference between MRI and PET-CT volume. MET uptake decreased in a row АА IDH− – АОД – AA IDH+, but the difference has not reached statistical significance. For wild-type AAs metabolic volume correlated with OS and PFS, meanwhile for IDH-mutant AAs tumor volume (measured by MRI) correlated only with PFS.</p></sec><sec><title>Conclusion</title><p>Conclusion. Present study based on the largest cohort of patients with anaplastic gliomas who underwent both MRI and PET with 11C-methionine. It turned out, that unlike grade II oligodendogliomas, AOs do not always demonstrate higher than their astrocytic counterparts MET uptake levels.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ПЭТ-КТ</kwd><kwd>11С-метионин</kwd><kwd>анапластическая астроцитома</kwd><kwd>анапластическая олигодендроглиома</kwd><kwd>IDH</kwd><kwd>метаболический объем опухоли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>PET-CT</kwd><kwd>11C-methionine</kwd><kwd>anaplastic astrocytomas</kwd><kwd>anaplastic oligodendrogliomas</kwd><kwd>IDH</kwd><kwd>metabolic tumor volume</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Минобрнауки в рамках научного проекта № 075-15-2020-809.</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">McNeill K.A.
