На сегодняшний день локальные методы занимают важное место в лечении ретинобластомы (РБ). Несмотря на имеющиеся в литературе публикации по локальному лечению, на сегодняшний день нет научных работ по сравнительному анализу его результатов в зависимости от стадии опухолевого процесса.</p><p>Цель исследования – оценить эффективность локальных офтальмологических методов лечения РБ на разных стадиях опухолевого процесса.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование вошли 274 пациента (357 глаз) с РБ, пролеченных с 2007 по 2022 г. Средний возраст больных на момент лечения составил 15 мес (от 0 до 74 мес), 58 % пациентов (n = 158) были мальчики, 42 % (n = 116) – девочки. Бинокулярная РБ имела место у 193 (70 %) пациентов, монокулярная – у 81 (30 %). У 59 (22 %) локальное лечение проводилось на единственном глазу. Распределение по стадиям и группам согласно классификации TNM и АВС-классификации РБ было следующим: стадия T1a (группа А) – 74 (21 %) глаза, T1b (группа В) – 122 (34 %), T2a (группа C) – 56 (15 %), T2b (группа D) – 104 (29 %), T3 (группа E) – 3 (1 %) глаза. В качестве локальных офтальмологических методов применялись лазерная термотерапия, криодеструкция и брахитерапия. Срок наблюдения составил от 6 до 158 мес (медиана – 49 мес).</p></sec><sec><title>Результаты</title><p>Результаты. Результаты локального лечения оценивались по следующим критериям: локальный контроль над опухолью, осложнения, сохранность глаз, компонентность лечения (количество методов для достижения регрессии опухоли), средние сроки регрессии и выживаемость (общая (ОВ) и безрецидивная (БРВ)). Результаты оценивались как в целом, так и в аспекте сравнительного анализа лечения на разных стадиях опухолевого процесса. Локального контроля над опухолью удалось достичь в 93 % случаев (n = 328), в 7 % (n = 26) был отмечен продолженный рост/ рецидив опухоли. Осложнения локального лечения наблюдались в 23 % случаев (n = 82). Удалось сохранить 329 (93 %) глаз, 25 (7 %) глаз были энуклеированы. Все 3 показателя были достоверны ниже в глазах пациентов с РБ группы D (p &lt; 0,01). При сравнительном анализе эффективности лечения на разных этапах стадия опухоли достоверно оказывала влияние на уровень локального контроля (p = 0,0012), процент осложнений (р = 0,001) и уровень сохранности глаз (р &lt; 0,0001) и не оказывала влияния на сроки регрессии опухоли (p = 0,3), компонентность лечения (p = 0,3) и показатели ОВ (p = 0,74) и БРВ (p = 0,3).</p></sec><sec><title>Заключение</title><p>Заключение. Локальные методы показали высокую эффективность в лечении РБ. Исходная стадия заболевания имеет большое значение в прогнозировании эффективности лечения. Лечение пациентов с РБ группы D по-прежнему остается трудной задачей, как в аспекте достижения локального контроля, так и сохранения глаза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Nowadays local modalities play an important role in retinoblastoma (Rb) treatment. Despite a great number of publications in scientific literature about local treatment there are no scientific works about comparative analysis of treatment results depending on tumor stage.</p><p>Purpose of the study – to evaluate the efficacy of local ophtalmological modalities of Rb treatment in different tumor stages.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study includes 274 patients (357 eyes) with Rb treated from 2007 to 2022. The mean patients’ age at the time of treatment was 15 months (from 0 to 74 months), 58 % patients were male, 42 % – female. 193 (70 %) patients presented with binocular Rb, 81 (30 %) – with monocular. In 59 (22 %) patients local treatment was performed on the single eye. Tumors’ distribution by stages was as followed: T1a stage (group А) – 74 (21 %) eyes, T1b (group В) – 122 (34 %) eyes, T2a (group C) – 56 (15 %) eyes, T2b (group D) – 104 (29 %) eyes, T3 (group E) – 3 (1 %) eyes. As local methods thermotherapy, cryotherapy and brachytherapy were applied. The follow-up varied from 6 to 158 months (median – 49 months).</p></sec><sec><title>Results</title><p>Results. Local treatment modalitites were analyzed by following criteria: local tumor control, complications, eye salvage, number of applied treatment modalities, mean regression period and survival (overall and disease-free). Results were analyzed overall and by comparative analysis on different tumor stages. Local tumor control was achieved in 93 % of cases (n = 328), in 7 % (n = 26) tumor relapse was observed. Local treatment complications were observed in 23 % of cases (n = 82). 329 eyes (93 %) were salvaged, 25 eyes (7 %) were enucleated. All of these criteria were significantly lower in eyes of patients with Rb of group D (p &lt; 0.01). Comparative analysis in different stages showed that tumor stage significantly affected local tumor control (p = 0.0012), complications’ frequency (р = 0.001), eye salvage percentage (р &lt; 0.0001) and doesn’t affect regression period (p = 0.3), number of treatment modalities (p = 0.3), overall (p = 0.74) and disease-free survival (p = 0.3).</p></sec><sec><title>Conclusion</title><p>Conclusion. Local methods showed high efficacy in Rb treatment. Initial tumor stage is relevant in the prognosis of the treatment efficacy. Treatment of patients with Rb of group D still remains to be challenging in aspects of local tumor control and eye salvage.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ретинобластома</kwd><kwd>локальное лечение</kwd><kwd>эффективность</kwd><kwd>стадии</kwd><kwd>сравнительный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>retinoblastoma</kwd><kwd>local treatment</kwd><kwd>efficacy</kwd><kwd>tumor stages</kwd><kwd>comparative analysis</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">Chantada G.L., Fandino A.C., Raslawski E.C., Manzitti J., de Dávila M.T, Casak S.J., Scopinaro M.J., Schvartzman E.
