Проведение ЛТ увеличивает выживаемость до 5 мес., проведение ХТ — от 5 до 26 мес. (в зависимости от статуса гена MGMT). Тем не менее, в отдельных случаях ЛТ и ХТ позволяет продлить жизнь более этого срока. Одним из механизмов, улучшающих прогноз таких больных является повышенная чувствительность к лекарственной терапии, которая обусловлена индивидуальными особенностями молекулярно-генетического статуса конкретной опухоли.</p></sec><sec><title>МЕТОД И ОПИСАНИЕ СЛУЧАЯ</title><p>МЕТОД И ОПИСАНИЕ СЛУЧАЯ: На основании материала, полученного у больного 39 лет при стереотаксической биопсии, гистологически и иммуногистохимически (GFAP (+) и Ki-67 18–20%) была верифицирована глиобластома с мутацией в гене IDH(R132H). Наличие мутации в генах IDH1 (экзон 4) и IDH2 (экзон 4) в опухолевой ткани определяли при помощи методики анализа кривых плавления ПЦР-продуктов с высоким разрешением (HRMA — High Resolution Melting Analysis) с последуюшим секвенированием ДНК. С помощью ПЦР в режиме реального времени в образце, выделенном из залитого в парафин фрагмента опухоли, определен уровень экспрессии гена MGMT, который оказался одним из самых низких (∆Сt=7,7) среди серии исследований, насчитывающих более 250 больных с разными опухолями головного мозга, которые были выполнены в нашей лаборатории.</p></sec><sec><title>РЕЗУЛЬТАТ</title><p>РЕЗУЛЬТАТ: Больному проведена протонная терапия в СОД (70 Гр) и ХТ темозоломидом (15 циклов) в адьювантном режиме с полным ответом на терапию. По данным МРТ безрецидивный период от момента диагностики на настоящий момент не достигнут и составляет 9 лет 2 мес., а ОВ — 10 лет 2 мес.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: Исключительно низкий уровень экспрессии мРНК гена MGMT (который способствует активному восстановлению опухолевых клеток после ХТ темозоломидом при его высоком уровне экспрессии) определил успешный результат химиолучевой терапии у неоперированного больного с достижением чрезвычайно длительной продолжительности жизни свыше 10 лет. Случай не окончен.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: Overall survival (OS) of untreated patients with glioblastoma (GB) typically does not exceed 2–4 months. Radiation without surgery prolongs OS up to 5 months and chemotherapy enables further prolongation up to 5–26 months (depending on MGMT status). In particular cases both modalities exert very long-lasting responses leading to survival times of the patients far beyond average values. These cases are thought to be at least in part characterized by very high sensitivity of the tumor to cytostatics which is due to certain individual molecular features of malignant cells.</p></sec><sec><title>METHOD AND CASE REPORT</title><p>METHOD AND CASE REPORT: 39 years old male patient was diagnosed with glioblastoma with mutation IDH1(R132H) on the basis of stereotaxic core biopsy specimen histologic (microscopic appearance, endothelium proliferation, necrosis) and IHC (GFAP+, Ki-67 18–20%) features. Mutations in IDH1 (exon 4) and IDH2 (exon 4) were tested by High Resolution Melting Analysis (HRMA) with subsequent sequencing. MGMT mRNA expression was assessed by RT-PCR in formalin fixed paraffin embedded tumor tissue. The expression level of the gene in this case appeared to be one of the lowest among series of more than 250 brain tumors which were evaluated in our laboratory (∆Ct=7,7).</p></sec><sec><title>RESULTS</title><p>RESULTS: The patient undergone 70Gy radiation (proton therapy) and 15 cycles of temozolomide monotherapy with a complete response to therapy. Until now the patient is still alive and response is ongoing. Progression-free survival is 9 years 2 months up to date and OS — 10 years 2 months.</p></sec><sec><title>CONCLUSIONS</title><p>CONCLUSIONS: We propose that in this case remarkably low expression of MGMT (which is when highly expressed considered to be the powerful tool for tumor cell recovery after temozolomide treatment) caused unprecedented suxcess of radiochemotherapy without surgery with 10+ years ОS.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>первичная глиобластома</kwd><kwd>длительная продолжительность жизни при глиобластоме</kwd><kwd>прогностические факторы</kwd><kwd>мутации в генах IDH1/2</kwd><kwd>ген MGMT</kwd></kwd-group><kwd-group xml:lang="en"><kwd>glioblastoma</kwd><kwd>long-term survival glioblastoma</kwd><kwd>prognostic factors</kwd><kwd>mutations IDH1/2</kwd><kwd>gene MGMT</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.
