Повысить безрецидивную выживаемость пациентов с местно-распространенным раком полости рта, языка и глотки путем использования химиолучевой терапии в режиме динамического ускоренного гиперфракционирования дозы излучения с сопутствующим бустом.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В рандомизированное проспективное клиническое исследование вошло 280 мужчин, соответствующих критериям включения, с диагнозом плоскоклеточного рака слизистой оболочки полости рта, языка и глотки III и IVА,В стадий. Все пациенты рандомизированы на основную и контрольную группы. В основной группе лучевая терапия проводилась в режиме динамического ускоренного гиперфракционирования дозы с сопутствующим бустом. В контрольной группе применялась лучевая терапия с классическим режимом фракционирования дозы излучения.</p></sec><sec><title>Результаты</title><p>Результаты. Для сравнительного анализа развития локо-регионарных рецидивов и безрецидивной выживаемости включены 172 пациента с полным ответом опухоли на химиолучевое лечение. В основной группе рецидивы первичной опухоли развились в 8 случаях, в регионарных лимфатических узлах – в 7 случаях. В контрольной группе локальные рецидивы выявлены у 16 пациентов, регионарные – у 13, а локо-регионарные – у 16 пациентов. Выявлены статистически значимые различия (р &lt; 0,001) показателей 5-летней безрецидивной выживаемости пациентов основной (58,2%±6) и контрольной (21,9%±6) групп.</p></sec><sec><title>Заключение</title><p>Заключение. Разработанный режим динамического ускоренного гиперфракционирования дозы с сопутствующим бустом является эффективным вариантом лучевого лечения пациентов с местно-распространенным раком орофарингеальной зоны. Применение данного режима при химиолучевом лечении приводит к уменьшению количества локорегионарных рецидивов и увеличению безрецидивной выживаемости.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: To increase the relapse-free survival rate of patients with locally advanced cancer of the oral cavity, tongue and pharynx using concurrent chemoradiоtherapy with dynamic accelerated hyperfractionation with concomitant boost.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A randomized, prospective clinical trial included 280 men with diagnosis of squamous cell carcinoma of the oral cavity, tongue and pharynx III and IVA, B stages. All patients randomized to the main and control groups. In the main group, radiation therapy was performed by dynamic accelerated hyperfractionation with concomitant boost. In the control group, the conventional chemoradiotherapy used.</p></sec><sec><title>Results</title><p>Results. For a comparative analysis of the development of loco-regional relapses and relapse-free survival, we included 172 patients with a complete tumor response. In the main group, recurrences of the primary tumor developed in 8 cases, in regional lymph nodes – in 7 cases. In the control group, local recurrences detected in 16 patients, regional – in 13, and locoregional – in 16 patients. Statistically significant differences (p &lt; 0.001) of 5-year relapse-free survival rate of patients of the main (58.2%±6) and control (21.9%±6) groups were revealed.</p></sec><sec><title>The conclusion</title><p>The conclusion. The chemoradiоtherapy with dynamic accelerated hyperfractionation with concomitant boost is an effective option for treatment of patients with locally advanced head and neck cancer. The use of this option leads to a decrease in the number of loco-regional relapses and an increase in relapse-free survival.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак головы и шеи</kwd><kwd>химиолучевая терапия с нетрадиционным режимом фракционирования</kwd><kwd>безрецидивная выживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>head and neck cancer</kwd><kwd>chemoradiotherapy with altered fractionation</kwd><kwd>loco-regional relapses</kwd><kwd>relapse-free survival</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">IAEA-TECDOC-1588: Transition from 2-D Radiotherapy to 3-D Conformal and Intensity Modulated Radiotherapy / IAEA, VIENNA, 2008. – 61 р.</mixed-citation><mixed-citation xml:lang="en">IAEA-TECDOC-1588: Transition from 2-D Radiotherapy to 3-D Conformal and Intensity Modulated Radiotherapy / IAEA, VIENNA, 2008. – 61 р.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Overgaard J.
