Многие исследования по сочетанной лучевой терапии (СЛТ) больных РПЖ демонстрируют хорошие онкологические результаты, однако до сих пор остается открытым вопрос определения последовательности этапов СЛТ и оптимального временного интервала между ними. Недостаточно рандомизированных исследований, которые могли бы подтвердить преимущества проведения контактной лучевой терапии на первом или втором этапе, а также определить наиболее эффективный временной промежуток между контактной и дистанционной лучевой терапией, связи с чем исследование различных методик СЛТ является перспективным направлением.</p><sec><title>Цель исследования</title><p>Цель исследования. Оценка результатов лечения больных РПЖ высокого риска в зависимости от последовательности этапов сочетанной лучевой терапии и временного интервала между ними.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. 53 больным РПЖ была выполнена сочетанная лучевая терапия на фоне длительной гормональной терапии (ГТ) с использованием на этапе брахитерапии радиоактивных источников 125I. Медиана наблюдения составила 38 месяцев. Возраст больных варьировал от 54 лет до 81 года. Все больные имели высокий риск по D’Amico. Больные были распределены на 2 группы: в первой группе брахитерапия выполнялась на первом этапе (n=31), а во второй — после дистанционной лучевой терапии (ДЛТ, n=22). Интервал между этапами СЛТ составлял: менее 4 недель (n=6), 4–7 недель (n=17), более 8 недель (n=30). ДЛТ проводилась в режиме стандартного фракционирования до суммарной дозы (СД) 46 Гр с использованием технологии VMAT. Имплантация постоянных источников 125I в предстательную железу обеспечивала СД до 110 Гр. ГТ выполнялась в неоадьювантном (2–4 месяца) и адьювантном режимах (не менее 24 месяцев).</p></sec><sec><title>Результаты</title><p>Результаты. У 5 (9,4%) пациентов наблюдалось прогрессирование заболевания: у 2 больных — только биохимические рецидивы, у 3 больных развились отдаленные метастазы. Медиана до прогрессирования заболевания составила 29,85 мес. Один больной с биохимическим рецидивом умер от острого инфаркта миокарда (1,9%). Медиана 5‑летней безрецидивной выживаемости больных составила 84,5±11,7% в первой группе, а во второй 83,5±9,1 (p=0,73). Не было выявлено достоверных различий по частоте токсичности в зависимости от последовательности этапов СЛТ.</p></sec><sec><title>Заключение</title><p>Заключение. СЛТ с использованием радиоактивных источников 125I на фоне длительной гормональной терапии является эффективным и безопасным методом лечения больных РПЖ высокого риска. При увеличении интервала между этапами СЛТ более 8 недель достоверность развития прогрессирования заболевания не выявлена. Изменение последовательности этапов СЛТ не влияет на эффективность лечения и частоту лучевых осложнений.</p></sec></abstract><trans-abstract xml:lang="en"><p>Radiotherapy is one of the radical treatment options used in patients with prostate cancer (PC). Many studies of combined radiotherapy (CRT) for PC have demonstrated good results in respect of response to treatment; however, the sequence of CRT steps and optimal interval between them have not been determined so far. Few randomized studies have been conducted in order to confirm the advantages of brachytherapy at the first or second step or determine the most effective interval between the contact and external beam RT. Therefore, it appears reasonable to evaluate different CRT techniques.</p><sec><title>Purpose</title><p>Purpose. The goal of the study was to evaluate the outcomes of PC treatment depending on the sequence of CRT steps and the interval between them.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 53 patients with PC received 125I radiation therapy in combination with long-term hormone therapy (HT). Median follow-up was 38 months. Patients’ age varied from 54 to 81 years. All patients were in a high-risk group according to the D’Amico Risk Classification System. The patients were allocated to two groups: in Group 1, brachytherapy was used as the first step (n=31); in Group 2, it was applied after external beam therapy (EBT). The interval between the CRT steps could be less than 4 weeks (n=6), 4 – 7 weeks (n=17) and more than 8 weeks (n=30). Standard fractionation EBT with a total dose of 46 Gy using the VMAT technique was conducted. 125I prostate implants were inserted to reach a total dose of 110 Gy. Neoadjuvant (2 – 4 months) and adjuvant (not less than 24 months) regimens of HT were applied.</p></sec><sec><title>Results</title><p>Results. Five (9.4 %) patients had disease progression; two of them experienced only biochemical recurrence; distant metastases were diagnosed in three patients. Median time to disease progression was 29.9 months. One patient with a biochemical relapse died of acute myocardial infarction (1.9 %). Median five-year disease-free survival was 84.5±11.7 % in Group 1 and 83.5±9.1 (p=0.73) in Group 2. There were no significant differences in the incidence of toxicity depending on the sequence of CRT steps.</p></sec><sec><title>Conclusion</title><p>Conclusion. EBT using 125I radiation sources in combination with long-term hormone therapy is an effective and safe treatment option for high-risk PC patients. No significant increase in the incidence of disease progression was observed when the interval between the CRT steps was increased to more than 8 weeks. Changes in the sequence of CRT steps do not affect response to treatment or incidence of radiation-related complications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>дистанционная конформная лучевая терапия</kwd><kwd>сочетанная лучевая терапия</kwd><kwd>брахитерапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>conformal external beam radiation therapy</kwd><kwd>combined radiotherapy</kwd><kwd>brachytherapy</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">Под ред.
