Correlation of multiparametric magnetic resonance imaging (mpMRI) data with RP results remains insufficiently studied, at the same time existing prognostic tools and nomograms show moderate effectiveness during third-party validation and have some drawbacks. Objective: to study pathomorphological results and evaluate the recurrence-free survival of patients after RP, depending on mpMRI data; develop a patient selection algorithm for NST.</p><p><bold>Materials and methods.</bold> The study included 95 patients with clinically localized prostate cancer (PCa), who underwent RP within 2012—2017. All mpMRI series were retrospectively reviewed and evaluated using the Prostate Imaging Reporting and Data System (PI-RADS) version 2 (v2) by one radiologist diagnostician who neither had access to database and clinical information about patients nor participated in data collection and statistical analysis. Patients were divided into 2 groups: low probability of PCa and suspected PCa (PI-RADS 2—3; n = 43); high and very high probability of PCa (PI-RADS 4—5; n = 52). We assessed the presence of positive surgical margins, as well as extracapsular extension and relapse-free survival. We also developed an algorithm to select patients for nerve-sparing PCa based on the PI-RADS category according to mpMRI data.</p><p><bold>Results.</bold> PI-RADS 2—3 group showed less positive surgical margins as compared to PI-RADS 4—5group (2.3 % versus 21.2 %; p = 0.025), as well as no cases of tumor extracapsular extension versus 36.5 % in PI-RADS 4—5group (p &lt;0.001). Patients with Gleason score 6 after demonstrated the same trends: extracapsular extension on the tumor side was observed in 0 and 33.3 % of cases (p &lt;0.001), positive surgical margins — in 2.4 and 15.2 % of cases (p = 0.046), respectively. An increase of the Gleason score after RP was observed in 12.2 % of patients of PI-RADS 2—3 group and in 30.3 % of PI-RADS 4—5 group (p = 0.04). Recurrence-free survival after 60 months was 93.0 and 71.1 %, respectively (p = 0.015).</p><p><bold>Conclusion.</bold> Risk categories for PCa according to mpMRI data are associated with pathomorphological results and recurrence-free survival after RP. Using PI-RADS v2 categories in the patient selection algorithm for NST optimizes the assessment of oncological safety and allows selecting a group of patients for a thorough individual analysis of the benefit/risk profile.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Селекция пациентов для радикальной простатэктомии (РПЭ) с применением нервосберегающей техники (НСТ) является принципиально важным вопросом оптимизации онкологических и функциональных результатов. Соотношение данных мультипараметрической магнитно-резонансной томографии (мпМРТ) с результатами РПЭ остается недостаточно исследованным, а предложенные к настоящему моменту прогностические инструменты и номограммы показывают умеренную эффективность при сторонней валидизации и не лишены недостатков.</p><p><bold>Цель исследования</bold> — изучить патоморфологические результаты и оценить безрецидивную выживаемость пациентов после РПЭ в зависимости от данных мпМРТ; разработать алгоритм селекции пациентов для НСТ.</p><p><bold>Материалы и методы</bold>. В исследование были включены 95 пациентов с клинически локализованным раком предстательной железы (РПЖ), перенесших РПЭ в период с 2012 по 2017 г. Все серии мпМРТ ретроспективно пересмотрены и оценены по системе Prostate Imaging Reporting and Data System (PI-RADS) version 2 (v2) одним лучевым диагностом, не имевшим доступ к базе данных и клинической информации о пациентах, не принимавшем участие в сборе и статистическом анализе информации. Пациенты были разделены на 2 группы: низкая вероятность РПЖ и подозрение на РПЖ (PI-RADS 2—3; n = 43); высокая и очень высокая вероятность РПЖ (PI-RADS 4—5; n = 52). Оценивали наличие положительных хирургических краев, экстракапсулярной экстензии, безрецидивную выживаемость. Разработан алгоритм селекции пациентов для РПЭ с НСТ на основании категории PI-RADS по данным мпМРТ.</p><p><bold>Результаты. </bold>В группе PI-RADS 2—3 по сравнению с группой PI-RADS 4—5 значительно реже отмечены положительные хирургические края (2,3 % против 21,2 %; p = 0,025), а также не выявлено ни одного случая экстракапсулярной экстензии со стороны очага против 36,5 % в группе PI-RADS 4—5 (p &lt;0,001). Среди пациентов с суммой баллов по шкале Глисона 6 после биопсии данные тенденции сохранялись: экстракапсулярная экстензия со стороны очага наблюдалась в 0 и 33,3 % случаев (р &lt;0,001), положительные хирургические края — в 2,4 и 15,2 % случаев (р = 0,046) соответственно. Увеличение суммы баллов по шкале Глисона после РПЭ отмечено у 12,2 % пациентов в группе PI-RADS 2—3 и у 30,3 % в группе PI-RADS 4—5 (р = 0,04). Через 60 мес безрецидивная выживаемость составила 93,0 и 71,1 % соответственно (р = 0,015).</p><p><bold>Заключение.</bold> Категории риска РПЖ по данным мпМРТ связаны с патоморфологическими результатами и безрецидивной выживаемостью после РПЭ. Использование категорий PI-RADS v2 в алгоритме селекции пациентов для НСТ способно оптимизировать оценку онкологической безопасности и позволяет выделить группу пациентов для тщательного индивидуального анализа профиля польза/риск.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>radical prostatectomy</kwd><kwd>magnetic resonance imaging</kwd><kwd>nerve-sparing technique</kwd><kwd>extracapsular extension</kwd><kwd>surgical margin</kwd><kwd>disease-free survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>радикальная простатэктомия</kwd><kwd>магнитно-резонансная томография</kwd><kwd>нервосберегающая техника</kwd><kwd>экстракапсулярная экстензия</kwd><kwd>хирургический край</kwd><kwd>безрецидивная выживаемость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Costello A.J.
