A standardized method of pathoanatomic examination includes assessing the quality and severity of surgical intervention with evaluation of both distal and circular resection margins, determining surgical clearance, pathological stage of the tumor ((y)pTpN), its histological type and the degree of differentiation. The results of morphological examination have great prognostic importance and serve as a basis for planning postoperative treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Основная роль морфологического исследования при хирургическом лечении рака прямой кишки заключается в определении индивидуальных факторов прогноза местного и общего рецидива. Стандартизированная методика патологоанатомического исследования включает оценку качества и радикальности хирургического вмешательства с исследованием как дистального, так и циркулярного краев резекции, определение хирургического клиренса, патоморфологической стадии опухоли ((у)рТр, ее гистологического типа и степени дифференцировки. Результаты морфологического исследования имеют важное прогностическое значение и служат основой для планирования послеоперационного лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Mesorectum</kwd><kwd>total mesorectal excision</kwd><kwd>circular resection margin</kwd><kwd>surgical clearance</kwd><kwd>predictors of local recurrence</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>мезоректум</kwd><kwd>тотальная мезоректумэктомия</kwd><kwd>циркулярный край резекции</kwd><kwd>хирургический клиренс</kwd><kwd>предикторы местного рецидива</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Злокачественные новообразования в России в 2016 г.
