Целью нашей работы является оценка дозной нагрузки и сопоставление ее с выявленными стресс-переломами у выбранной группы пациентов. Материалы и методы. В период с 2011 по 2015 год 129 пациентам с морфологически подтвержденным биопсией плоскоклеточным раком анального канала проведен курс химиолучевой терапии технологией IMRT, химиотерапии на основе препарата митомицин. МРТ проводилось для стадирования, оконтуривания планов лучевой терапии, оценки эффекта лечения. Результаты. По данным МРТ у 5 (3,9 %) пациенток в возрасте 54-75 лет в стадии опухолевого процесса IIIA/IIIB в течение года после окончания химиолучевой терапии выявлены стресс-переломы крестца с отсутствием клинических проявлений. В нашем исследовании все пациентки, у которых случился стресс-перелом, получили на область крестца СОД, не превышающую 45 Гр за весь курс лучевого лечения. Для оценки дозы лучевой терапии на головки бедренных костей они были оконтурены как отдельная структура у 10 больных: D2 % составило 41,62 ± 0,84 Гр, V45 - 3,08 ± 1,75 см3. Выводы. Стресс-переломы являются редким, но значимым осложнением современной лучевой терапии и требуют современных методов диагностики (МРТ). Поскольку современное лечение предусматривает комбинацию лучевой терапии и химиотерапии, большие дозы лучевой терапии на отдельные области тазовых костей могут увеличить риск возникновения стресс-перелома.</p></abstract><trans-abstract xml:lang="en"><p>Objective. There are some descriptions of different boness stress fractures in existing literature, among them fractures of os sacrum and femoral heads. We estimated radiotherapy dose on bones mentioned above and collated them with the revealed stress fractures in selected patients. Materials and methods. Since 2011 till 2015 year 129 patients with morphologically proven squamous cell anal cancer were treated with chemoradiotherapy IMRT and mytomycin-based CT. Results. Stress fractures of a sacrum without any symptoms was diagnosed on MRI scan in 5 (3.9 %) patients, aged 54-75, with stages IIIA/IIIB within one year since treatment finished. In our patients no one of those with stress fracture hadn ’t radiotherapy dose more than 45 Gy on sacrum. For dose estimation on femoral heads they were contoured as separate structure in 10 patients: D2 % was 41.62 ± 0.84 Gy, V45 was 3.08 ± 1.75 cm3. Conclusion. Stress fractures are rare but important complication of modern radiation therapy and call for modern diagnostic methods. State-of-art treatment involves radiotherapy and chemotherapy, and higher doses of radiotherapy on distinct regions of pelvic bones may increase the risk of stress fracture.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>плоскоклеточный рак анального канала</kwd><kwd>лучевая терапия с модуляцией интенсивности</kwd><kwd>стресс-перелом</kwd><kwd>магнитно-резонансная томография</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">Dongryul Oh, Seung Jae Huh.
