Neoplastic stromal cells have a phenotype of immature osteoblasts synthesizing various cytokines and molecular factors leading to excessive activation of osteoclastogenesis and increased osteolysis in giant cell tumor of bone. Long-term treatment with denosumab is recommended for unresectable or disseminated disease.</p><p>A clinical case of long-term treatment with denosumab of initially generalized giant cell tumor of the right ischial bone with metastases to the lungs is presented. Stabilization of the process was first recorded 3 months after the start of therapy and has been maintained to date. The patient was transferred to a maintenance regimen 3 years after the start of treatment. The treatment was not accompanied by adverse events characteristic of bone-modifying agents.</p><p>Long-term use of denosumab allowed effective control of the tumor process and maintenance of satisfactory quality of life of the patient. Maintenance regimen of denosumab administration was not accompanied by a decrease in treatment effectiveness.</p></abstract><trans-abstract xml:lang="ru"><p>Гигантоклеточная опухоль кости – локально-агрессивное первичное новообразование кости, поражающее преимущественно пациентов в возрасте 20–50 лет. В этой опухоли неопластические стромальные клетки обладают фенотипом незрелых остеобластов, синтезирующих различные цитокины и молекулярные факторы, приводящие к чрезмерной активации остеокластогенеза и усилению остеолиза. При неоперабельном или диссеминированном заболевании рекомендовано длительное лечение деносумабом.</p><p>Представлен клинический случай длительного лечения деносумабом исходно генерализованной гигантоклеточной опухоли правой седалищной кости с метастазами в легкие. Стабилизация процесса впервые зафиксирована через 3 мес после начала терапии и сохраняется по настоящее время. Пациентка переведена на поддерживающий режим спустя 3 года после начала лечения. Лечение не сопровождалось нежелательными явлениями, характерными для остеомодификаторов.</p><p>Длительное применение деносумаба позволило эффективно контролировать опухолевый процесс и сохранить удовлетворительное качество жизни пациентки. Переход на поддерживающий режим введения деносумаба не сопровождался снижением эффективности лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>giant cell tumor of bone</kwd><kwd>denosumab</kwd><kwd>long-term treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гигантоклеточная опухоль кости</kwd><kwd>деносумаб</kwd><kwd>длительное лечение</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">Andrievskikh E.A., Zinoviev G.V., Gafton G.I. et al.
