Лангергансоклеточный гистиоцитоз (ЛКГ) является самым распространённым вариантом из всех гистиоцитозов и относится к потенциально смертельным заболеваниям, в исходе которого имеет большое значение ранняя постановка диагноза. На данный момент роль ядерной медицины в диагностике ЛКГ не определена. В лаборатории радиоизотопной диагностики НМИЦ онкологии им. Н.Н. Блохина накоплен многолетний опыт наблюдения детей с ЛКГ.</p></sec><sec><title>Цель</title><p>Цель: Провести ретроспективный и проспективный анализ результатов остеосцинтиграфии у пер- вичных пациентов детского возраста с ЛКГ и рассчитать диагностическую эффективность остеосцинтиграфии.</p></sec><sec><title>Материал и методы</title><p>Материал и методы: Проанализированы результаты исследований 60 первичных пациентов с верифицированным диагнозом ЛКГ с 2014 г. по 2019 г. Сканирование на томографе Symbia E, T2 (Siemens, Германия) проводили в режиме «всё тело» с остеотропным РФП 99mТс-технефором через 3 ч после в/в введения. Средний возраст пациентов составил 5,6 лет.</p></sec><sec><title>Результаты</title><p>Результаты: У 60 пациентов при остеосцинтиграфии было визуализировано 88 очагов в костях с па- тологическим уровнем накопления РФП. Из них: 84 с повышенным уровнем аккумуляции (&gt;120 %); 3 с незначительно повышенным (100–120 %) и 1 с пониженным (&lt;100 %) уровнем. Средний уровень накопления РФП в патологическом очаге составил 268 %. Максимальный – 1422 % у пациента с субтотальным поражением бедренной кости. Минимальный — 60 % у пациента с крупным литическим очагом в орбите. При рентгенографии зафиксировано 97 очагов остеолитической деструкции. У трех пациентов с полиоссальной формой поражения при остеосцинтиграфии обнаружены дополнительные очаги поражения, в дальнейшем подтверждённые рентгенологически. При остеосцинтиграфии были не распознаны 8 патологических очагов у 8 пациентов.</p></sec><sec><title>Выводы</title><p>Выводы: Показатели диагностической эффективности ОСГ в выявлении очагов остеодеструкции у первичных пациентов с ЛКГ составляют: чувствительность — 91,6 %, специфичность — 50,0 %, от- рицательная прогностическая ценность — 11,1 %, положительная прогностическая ценность — 98,9 %.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: Histiocytosis is a heterogeneous group of rare diseases of unknown etiology. LCH is characterized by an abnormal proliferation of histiocytes (activated dendric cells and macrophages). Langerhans cell histiocytosis (LCH) is the most common form of histiocytosis, it is a potentially fatal diseases. Early detection of LCH plays an important role in its prognosis and outcome. However, the role of advanced methods of nuclear medicine in diagnosis of LCH is still to be researched. We have long-term experience in observing pediatric patients with LCH. Taking into the account the difficulty of diagnostic task for bone scintigraphy in identifying lytic bone destruction, we stated the following objective of the study.</p></sec><sec><title>Purpose</title><p>Purpose: Retrospective and prospective analysis of bone scintigraphy examinations of treatment-naive pediatric patients with LCH and calculate the diagnostic efficacy of bone scintigraphy. Material and methods: We analyzed 60 examinations of treatment-naive pediatric patients with proven case of LCH (2014-2019). The scanning was performed using whole body mode, 3 hours after intravenous injection of bone-seeking radiopharmaceutical 99mTc-MDP on Symbia E, T2 (Siemens, Germany). The median age was 5.6 years.</p></sec><sec><title>Results</title><p>Results: During examination we visualized 88 lesions with pathological level of accumulation of radiopharmaceutical in 60 patients. 84 with high level of accumulation (&gt;120 %); 3 with slightly increased level of accumulation (100–120 %) and 1 with lower than normal level of accumulation (&lt;100 %). The median level of accumulation of radiopharmaceutical was 268 %. Max level of accumulation was 1422 % (patient with subtotal involvement of femoral bone). Min — 60 % (patient with lytic destruction in orbital bone). During X-Ray we found out 97 pathological focuses of bone lytic destruction. In 3 patients with polyostotic form we found extra focuses on scintigraphy, which were confirmed with following examination and X-Ray. 8 lesions were not found on scintigraphy in 8 patients.</p></sec><sec><title>Сonclusions</title><p>Сonclusions: We evaluated diagnostic accuracy of bone scintigraphy with 99mTc-MDP in treatment-naïve pediatric patients with proven case of LCH. Sensitivity, specificity, NPV and PPV — 91.6, 50.0, 11.1, 98.6 %, respectively.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лангергансоклеточный гистиоцитоз</kwd><kwd>онкопедиатрия</kwd><kwd>остеосцинтиграфия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Langerhans cell histiocytosis</kwd><kwd>oncology</kwd><kwd>pediatry</kwd><kwd>bone scan</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">Львов АН, Волощук ИН, Варшавский ВА и др.
