B ретроспективное исследование включены 639 пациентов с морфологически установленным диагнозом диффузной глиомы взрослого типа головного мозга с различной степенью злокачественности (grade 2—4) и IDHwt, пролеченных в 2017—2021 гг. У 67 (10,5 %) пациентов степень злокачественности опухоли соответствовала grade 2, у 59 (9,2 %) — grade 3 и 513 (80,3 %) — grade 4 (глиобластома, ΓБ).</p></sec><sec><title>Результаты</title><p>Результаты. Результаты лечения пациентов с диффузными глиомами взрослого типа с grade 2 (медиана общей выживаемости (ОB) не достигнута, 5-летняя ОB 56,0±6,9 %) были статистически значимо лучше в сравнении с пациентами с grade 3 (медиана 11,5±2,8 мес и 5-летняя ОB 9,5±4,9 %; p&lt;0,001) и grade 4 (медиана 9,4±0,6 мес и 5-летняя ОB 2,1±1,0 %; p&lt;0,001). Статистически значимых различий в ОB пациентов с grade 3 и grade 4 получено не было (p=0,638).</p></sec><sec><title>3аклюцение</title><p>3аклюцение. Bключение пациентов с диффузными глиомами взрослого типа со степенью злокачественности опухоли grade II в нозологический тип «глиобластома» только на основании IDHwt нецелесообразно вследствие более высокой ОB в данной подгруппе опухолей. B случае планирования клинических исследований и включения в них пациентов с диффузными глиомами взрослого типа со степенью злокачественности опухоли grade 2—III с IDHwt в обязательном порядке должны проводится дополнительные молекулярно-генетические исследования (определение амплификации EGFR, мутации TERTp, приобретения хромосомы 7 и потери хромосомы 10) с целью определения возможности отнесения этих опухолей к нозологической категории «глиобластома».</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To establish the prognostic value of the malignancy grading of adult-type diffuse gliomas in the absence of a mutation in the IDH gene (IDHwt).</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The retrospective study included 639 patients with a morphologically established diagnosis of diffuse glioma of the adult type of the brain with varying malignancy grading (grade 2—4) and IDHwt, treated in 2017— 2021. In 67 (10,5 %) patients, the malignancy grading of the tumor corresponded to grade 2, in 59 (9,2 %) — grade 3 and 513 (80,3 %) — grade 4 (glioblastoma, GBM).</p></sec><sec><title>Results</title><p>Results. The results of treatment of patients with diffuse adult gliomas grade 2 (median overall survival (OS) not reached, 5-year OS 56,0±6,9 %) were statistically significantly better compared with patients with grade 3 (median and 5-year OS 11,5±2,8 months and 9,5±4,9 %; p&lt;0,001) and grade 4 (GBM) (median and 5-year OS 9,4±0,6 months and 2,1±1,0 %; p&lt;0,001). There were no statistically significant differences in OS between patients with grade 3 and grade 4 GBM) (p=0,638).</p></sec><sec><title>Conclusion</title><p>Conclusion. Inclusion of patients with diffuse adult-type gliomas with grade 2 into the nosological type «glioblastoma» only on the basis of IDHwt is inappropriate due to the higher OS in this subgroup of tumors. In the case of planning clinical trials and including patients with diffuse adult-type gliomas grade 2—3 with IDHwt, additional molecular genetic studies must be carried out (determining EGFR amplification, TERTp mutation, acquisition of chromosome 7 and loss of chromosome 10 ) in order to determine the possibility of classifying these tumors into the category «glioblastoma».</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диффузные глиомы головного мозга</kwd><kwd>отсутствие мутации в гене IDH</kwd><kwd>выживаемость взрослых пациентов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>diffuse brain gliomas</kwd><kwd>absence of mutation in the IDH gene</kwd><kwd>survival of adult patients</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">Torp S.
