Numerous clinical studies have made it possible to obtain standard protocols for the treatment of primary brain tumors; however, protocols for the treatment of recurrent tumors have not been developed. The choice of treatment usually includes reoperation, systemic chemotherapy, and reirradiation alone or in combination. However, the treatment of recurrent glial tumors is challenging given the lack of effective treatment options and the lack of randomized controlled trials on which to base therapy.</p> <p><bold>AIM:</bold> To determine the most important prognostic factors, as well as the most effective treatment option in patients with continued growth of primary low-grade gliomas of the brain.</p> <p><bold>METHODS:</bold> This study included 40 patients with a confirmed diagnosis of progression of low-malignant glial brain tumors, who underwent inpatient treatment at the Chelyabinsk Regional Clinical Center of Oncology and Nuclear Medicine from 2007 to 2022. The ratio of men and women: 1:1.5. The mean age was 45.6±11.5 years. Patients with grade I astrocytomas predominated (n=23), oligodendroglioma was diagnosed in 8 patients.</p> <p>Reoperation was performed in 11 patients as the first stage of progression treatment. In 7 cases, monochemotherapy with temozolomide was performed. Repeated radiation therapy was performed in 29 patients, of which: 9 patients received a course of combined photon-neutron therapy; 9 patients — stereotactic radiation therapy (was performed on the CyberKnife device); 11 patients — external beam radiation therapy.</p> <p><bold>RESULTS:</bold><bold> </bold>The median overall survival (OS) for all patients with continued growth of low-grade cerebral gliomas after treatment was 120 months. 1-year OS — 97.3%; 3-year — 86.8%; 5-year — 78.2%. Median OS after relapse treatment was 36 months. The median OS was higher in the age group under 50 compared to the older age group: 120 and 95 months (p &gt;0.05).</p> <p>The best results of treatment were noted in patients who underwent reoperation followed by a course of radiation therapy or chemotherapy with temozolomide for 48 months and 36 months respectively (p &gt;0.05). When analyzing the results of treatment after a course of repeated radiation therapy in an independent variant, there were undoubted advantages in patients who underwent stereotactic radiation therapy and photon-neutron therapy for 60 months and 24 months respectively (p &lt;0.05).</p> <p><bold>CONCLUSIONS:</bold> The optimal approach to the treatment of patients with continued growth of primary low-grade glioma brain tumors is to perform a second operation, followed by radiation therapy or chemotherapy. The method of choice for a repeat course of radiotherapy may be photon-neutron therapy or stereotactic radiation therapy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Несмотря на улучшение результатов лечения опухолей головного мозга за последнее десятилетие, у большинства больных спустя 1–2 года после проведённого лечения возникают рецидивы заболевания. Проведённые многочисленные клинические исследования позволили получить стандартные протоколы лечения первичных опухолей головного мозга, вместе с тем не разработаны протоколы лечения рецидивных опухолей. Методом выбора обычно является проведение повторной операции, системной химиотерапии, а также повторного облучения — по отдельности или в комбинации друг с другом. Однако лечение рецидивирующих глиальных опухолей — сложная задача, учитывая нехватку эффективных вариантов лечения и отсутствие рандомизированных контролируемых исследований, на которых построилась бы базисная терапия.</p> <p><bold>Цель —</bold> определение наиболее важных прогностических факторов, а также оптимального варианта лечения у пациентов с продолженным ростом первичных низкозлокачественных глиом головного мозга.</p> <p><bold>Методы. </bold>В данное исследование вошло 40 пациентов с подтверждённым диагнозом «прогрессирование низкозлокачественных глиальных опухолей головного мозга», кому в период с 2007 по 2022 год было проведено стационарное лечение в Челябинском областном клиническом центре онкологии и ядерной медицины. Соотношение мужчин и женщин: 1:1,5. Средний возраст составил 45,6±11,5 года. Преобладали больные с низкозлокачественными астроцитомами (Grade I, n=23), у 8 пациентов была диагностирована олигодендроглиома.</p> <p>У 11 пациентов была проведена реоперация как первый этап лечения прогрессии. В 7 случаях была проведена монохимиотерапия темозоломидом. Повторная лучевая терапия была выполнена 29 пациентам, из них: 9 больных получили курс сочетанной фотонно-нейтронной терапии (СФНТ); 9 — курс стереотаксической лучевой терапии (СТЛТ) на аппарате CyberKnife; 11 — курс дистанционной лучевой терапии.</p> <p><bold>Результаты.</bold> Медиана общей выживаемости (ОВ) для всех пациентов с продолженным ростом низкозлокачественных глиом головного мозга после проведённого лечения составила 120 мес (95% доверительный интервал — 91,6–148,3). Показатели 1-летней ОВ — 97,3%; 3-летней — 86,8%; 5-летней — 78,2%. Медиана ОВ после лечения рецидива — 36 мес (95% доверительный интервал — 15,5–56,4). Медиана ОВ была выше в возрастной группе до 50 лет, в сравнении с более старшей возрастной группой: 120 и 95 мес (<italic>p &gt;</italic>0,05).</p> <p>Наилучшие результаты лечения были отмечены у пациентов после реоперации с последующим проведением курса лучевой терапии или химиотерапии темозоломидом — 48 мес и 36 мес соответственно (<italic>p </italic>&gt;0,05). При анализе результатов лечения после курса повторной лучевой терапии в самостоятельном варианте несомненные преимущества были у тех больных, кому проводилась СТЛТ и СФНТ — 60 мес и 24 мес соответственно (<italic>p &lt;</italic>0,05).</p> <p><bold>Заключение. </bold>Оптимальным подходом к лечению больных с продолженным ростом первичных низкозлокачественных глиом головного мозга является повторная операция с последующим проведением лучевой терапии или химиотерапии. Методом выбора при проведении повторного курса лучевой терапии могут быть СФНТ или СТЛТ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>recurrent</kwd><kwd>astrocytoma</kwd><kwd>temozolomide</kwd><kwd>stereotactic radiation therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рецидив</kwd><kwd>астроцитома</kwd><kwd>темозоломид</kwd><kwd>стереотаксическая лучевая терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Louis D, Perry A, Wesseling P, et al.
