Целью работы является оценка дозовой нагрузки и сопоставление ее с выявленными стресс-переломами у выбранной группы пациентов.</p></sec><sec><title>Материал и методы</title><p>Материал и методы: С 2011 по 2015 гг. 129 пациентам с морфологически подтвержденным биопсией плоскоклеточным раком анального канала проведен курс химиолучевой терапии по технологии IMRT + химиотерапия на основе препарата митомицин. МРТ проводилась для стадирования, оконтуривания планов лучевой терапии и оценки эффекта лечения.</p></sec><sec><title>Результаты</title><p>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. У всех больных доза на область крестца, как критической структуры, не превышала 30–35 Гр за весь курс лучевого лечения. Оценка дозы лучевой терапии на головки бедренных костей проведена у 10 больных: D2 % составила 41,62 ± 0,84 Гр, V45 – 3,08 ± 1,75 см3.</p></sec><sec><title>Выводы</title><p>Выводы: Стресс-переломы являются редким, но значимым осложнением химиолучевой терапии и требуют современных методов диагностики (МРТ и КТ). Современное лечение предусматривает химиолучевое воздействие в радикальной дозе. Комбинация технологий конформной лучевой терапии на нижние отделы таза, люмбо-сакральный и подвздошный отделы позволяет контролировать дозу лучевого воздействия на здоровые структуры, не превышая допустимую (по данным QUANTEC).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose: There are some descriptions of different bones’s stress fractures in radiation therapy, 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.</p></sec><sec><title>Material and methods</title><p>Material and methods: Since 2011 till 2015 129 patients with morphologically proven squamous cell anal cancer were treated with chemoradiotherapy – IMRT and mytomycin-based CT.</p></sec><sec><title>Results</title><p>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 – 3.08 ± 1.75 cm3.</p></sec><sec><title>Conclusion</title><p>Conclusion: Stress fractures are rare but important complication of modern radiation therapy and call for modern diagnostic methods  (MRI). 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></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>плоскоклеточный рак анального канала</kwd><kwd>лучевая терапия  с модуляцией интенсивности (IMRT)</kwd><kwd>стресс-перелом</kwd><kwd>магнитно-резонансная томография (МРТ)</kwd></kwd-group><kwd-group xml:lang="en"><kwd>anal canal</kwd><kwd>squamous cell carcinoma</kwd><kwd>intensity modulated radiation therapy (IMRT)</kwd><kwd>stress fracture</kwd><kwd>magnetic resonance imaging (MRI)</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.
