However, specific anatomical location of the tumor and/or its spread may hinder its complete excision or result in poor functional outcomes. Currently, combination treatment that includes preoperative denosumab and surgery is preferable. It saves patients’ lives and improves their quality of life. Reduction of local recurrence rate by combination therapy for giant-cell tumors of the bone is being actively studied now.</p><p><bold>Objective </bold>– to analyze treatment outcomes of patients with giant-cell tumors of the bone, including those who received combination treatment that included preoperative therapy with denosumab followed by surgery.</p><p><bold>Materials and methods. </bold>This study included 277 patients with giant-cell tumors treated in N.N. Blokhin National Cancer Research Center between 2005 and 2020. The mean duration of follow-up was 56 months. Study participants were divided into two groups. Group 1 included patients who received surgical treatment alone (n = 212), whereas Group 2 comprised patients who received combination treatment (n = 65). Neoadjuvant therapy included subcutaneous denosumab 120 mg on days 1, 8, 15, and 28, then every 4 weeks until stable effect. There were two variants of surgical treatment: radical (removal by a single block or segmental resection with defect replacement, with or without fixation) and non-radical (excochleation or marginal resection with defect replacement, with or without fixation).</p><p><bold>Results. </bold>During treatment, patients in Group 2 had a significantly milder pain syndrome (assessed both using the visual analog scale for pain and Watkins scale) compared to Group 1. In case of radical surgery, the incidence of local recurrence was 12 % and 0 % in Groups 1 and 2, respectively; the difference was significant (р &lt;0.05). Tumor location and volume of surgery played an important role in disease recurrence (р &lt;0.05). The incidence of complications after radical surgery was 36.9 % and 12.5 % in Groups 1 and 2, respectively; the difference was significant (р &lt;0.05). In addition to that, neoadjuvant therapy with denosumab substantially reduced the duration of surgery and blood loss in patients with challenging anatomical location of the tumor (р &lt;0.05).</p><p><bold>Conclusion.</bold> Combination treatment for giant-cell tumors that includes neoadjuvant therapy with denosumab reduces the risk of recurrence, duration of surgery, blood loss, and the risk of postoperative complications. However, it is important to consider tumor location and the volume of surgery. Since the disease is quite rare, further study of long-term efficacy and safety of combination treatment for giant-cell tumors, including rare ones and those with challenging anatomical location, is necessary.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Стандартом лечения гигантоклеточной опухоли кости является хирургическое вмешательство, проведенное в радикальном объеме. Однако в связи с определенной локализацией и/или распространенностью новообразования операция не всегда выполнима или может привести к неудовлетворительным функциональным результатам. В настоящее время предпочтение отдается комбинированному подходу, предполагающему проведение предоперационной терапии деносумабом с последующим хирургическим лечением. Это позволяет сохранить и улучшить качество жизни пациентов. Снижение частоты местного рецидива при комбинированной терапии гигантоклеточной опухоли кости является предметом многих исследований.</p><p><bold>Цель исследования </bold>– анализ результатов лечения пациентов с гигантоклеточной опухолью кости, в том числе с применением комбинированного метода, включающего предоперационную терапию деносумабом и последующее хирургическое вмешательство.</p><p><bold>Материалы и методы. </bold>В исследование включены 277 пациентов с гигантоклеточной опухолью, проходившие лечение в Национальном медицинском исследовательском центре онкологии им. Н.Н. Блохина» в 2005–2020 гг. Средний срок наблюдения составил 56 мес. Были проанализированы 2 группы больных. В 1-ю группу вошли пациенты, которым проводилось только хирургическое лечение (n = 212), а во 2-ю – пациенты, получавшие комбинированную терапию (n = 65). Неоадъювантная терапия с использованием деносумаба проводилась по схеме: 120 мг подкожно в 1, 8, 15 и 28-й дни 1-го месяца и далее 1 раз в 28 дней до стабилизации эффекта. Хирургическое лечение выполнялось в 2 вариантах: радикальном (удаление единым блоком или сегментарная резекция с замещением дефекта, с фиксацией или без нее) и нерадикальном (экскохлеация или краевая резекция с замещением дефекта, с фиксацией или без нее).</p><p><bold>Результаты.</bold> На фоне лечения во 2-й группе выявлено значительное снижение болевого синдрома по визуальноаналоговой шкале боли и шкале Watkins (p &lt;0,001) по сравнению с 1-й группой. Частота местного рецидива при радикальном объеме операции в 1-й группе составила 12 %, во 2-й – 0 %. Снижение частоты местного рецидива во 2-й группе статистически значимо (р &lt;0,05). Большую роль в развитии рецидива заболевания играют локализация заболевания и объем оперативного вмешательства (р &lt;0,05). Частота осложнений после радикального хирургического лечения в 1-й группе составила 36,9 %, во 2-й – 12,5 %. Снижение частоты осложнений во 2-й группе статистически значимо (р &lt;0,05). Также неоадъювантная терапия с использованием деносумаба значительно влияет на сокращение времени операции и объема кровопотери при анатомически сложных локализациях опухоли (р &lt;0,05).</p><p><bold>Заключение. </bold>Комбинированное лечение гигантоклеточной опухоли, включающее неоадъювантную терапию с использованием деносумаба, позволяет снизить риск рецидива заболевания, а также сократить время операции, объем кровопотери и уменьшить риск послеоперационных осложнений. Однако нужно учитывать локализацию новообразования и объем возможного хирургического вмешательства. В связи с редкостью заболевания необходимо дальнейшее изучение отдаленных результатов эффективности и безопасности комбинированных методов лечения гигантоклеточной опухоли, в том числе при редких и анатомически сложных ее локализациях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>giant cell tumor</kwd><kwd>denosumab</kwd><kwd>bone tumor</kwd><kwd>RANKL</kwd><kwd>RANK</kwd><kwd>local recurrence</kwd><kwd>surgery time</kwd><kwd>blood loss</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гигантоклеточная опухоль</kwd><kwd>деносумаб</kwd><kwd>опухоль кости</kwd><kwd>RANKL</kwd><kwd>RANK</kwd><kwd>местный рецидив</kwd><kwd>время операции</kwd><kwd>кровопотеря</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rockberg J., Bach B.A., Amelio J. et al.
