Современные подходы к лечению рака прямой кишки диктуют необходимость персонализированного подхода не только в назначении неоадъювантной терапии, но и ее коррекции после завершения, в зависимости от местного распространения опухоли и с учетом критериев риска возникновения рецидивов. Цель. Повысить информативность мультипараметрической магнитно-резонансной томографии (мпМРТ) в оценке эффективности лечения и прогноза течения местнораспространенного рака прямой кишки (мрРПК) после неоадъювантного лечения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Ретроспективно изучены данные 112 больных с мрРПК, получивших комбинированное лечение в объеме предоперационной химиолучевой терапии (ХЛТ) (85 больных) и ХЛТ дополненной неоадъювантной полихимиотерапией (27 больных) с последующим хирургическим вмешательством. Всем пациентам выполнялась мпМРТ перед неоадъювантным лечением и через 8-10 недель (медиана 8,4 недели) после ее завершения для оценки ответа. Для сравнительного анализа были включены следующие критерии: состояние циркулярного края резекции (CRM), наличие или отсутствие экстрамуральной венозной инвазии (EMVI), глубина инвазии мезоректальной клетчатки первичной опухолью (T), наличие или отсутствие метастатически пораженных мезорек-тальных лимфатических узлов (N) и степень регресса опухоли (TRG). Для определения диагностических возможностей мпМРТ проводилось сравнение данных МРТ с результатами патоморфологии.</p></sec><sec><title>Результаты</title><p>Результаты. Наибольшей диагностической эффективностью, в сравнении с патоморфологическими результатами, обладали такие МР-критерии, как: N-критерий (чувствительность 81,2%, специфичность 95,6%, точность 91,6%), circumferential resection margin — CRM (чувствительность 84%, специфичность 83,9%, точность 83,9%) и extramural venous invasion — EMVI (чувствительность 75%, специфичность 85,4%, точность 83,9%). В то время как диагностические эффективности Т-критерия (чувствительность 95%, специфичность 59,6%, точность 78,6%) и tumour regression grade — TRG (чувствительность 46%, специфичность 86,3%, точность 72,3%) были недостаточно высокими.</p></sec><sec><title>Заключение</title><p>Заключение. Использование критериев N-, CRM иEMVI в оценке эффективности неоадъювантного лечения местнораспространенного РПК позволяет повысить эффективность мультипараметрической МРТ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Modern treatment strategies of colorectal cancer determine the need for a personalized approach not only in administration of neoadjuvant therapy, but also in correction after its completion, depending on the tumor local extent and taking into account the risk of relapse. Objective. To incrise the diagnostic performance of multiparametric MRI (mpMRI) in assessing the effectiveness of treatment and predicting the clinical course of locally advanced rectal cancer (LARC) after neoadjuvant treatment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 112 patients with LARC who received preoperative chemoradiotherapy (CRT) (85 patients) and CRT supplemented with neoadjuvant polychemotherapy (27 patients) followed by surgery were enrolled in retrospective study. All the patients underwent mpMRI before neoadjuvant treatment and 8-10 weeks (median 8,4 weeks) after its completion in order to evaluate the tumor response. The parameters examined included circumferential resection margin (CRM), extramural venous invasion (EMVI), T stage (T) and N stage (N), TRG (TRG). To determine the diagnostic performance of mpMRI, obtained data are compared with pathomorphology.</p></sec><sec><title>Results</title><p>Results. The MRI parameters with the highest diagnostic performance, in comparison with pathomorphological results, were: N stage (sensitivity 81,2%, specificity 95,6%, accuracy 91,6%), CRM (sensitivity 84%, specificity 83,9%, accuracy 83,9%) and EMVI (sensitivity 75%, specificity 85,4%, accuracy 83,9%). The diagnostic performance of T staging (sensitivity 95%, specificity 59,6%, accuracy 78,6%) and TRG (sensitivity 46%, specificity 86,3%, accuracy 72,3%) were not high enough.</p></sec><sec><title>Conclusions</title><p>Conclusions. Multiparametric MRI has high sensitivity and specificity in assessing the effectiveness of neoadjuvant treatment of locally advanced rectal cancer, and that allows to choose proper patient management.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак прямой кишки</kwd><kwd>диагностика</kwd><kwd>оценка распространенности</kwd><kwd>магнитно-резонансная томография (МРТ)</kwd><kwd>циркулярный край резекции</kwd><kwd>экстрамуральная венозная инвазия</kwd><kwd>степень регресса опухоли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rectal cancer</kwd><kwd>method</kwd><kwd>diagnostics</kwd><kwd>disease extent assessment</kwd><kwd>magnetic resonance imaging (MRI)</kwd><kwd>circumferential resection margin (CRM)</kwd><kwd>extramural venous invasion (EMVI)</kwd><kwd>tumour regression grade (TRG)</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">Sauer R., Becker H., Hohenberger W., Rodel C., Wittekind C., Fietkau R., Martus P., Tschmelitsch J., Hager E., Hess C.
