Сохраняется высокая заболеваемость раком желудка, несмотря на увеличение удельного веса I–II стадии, — в 2019 году он составил 37,1 %. Хирургический метод лечения остается актуальным даже у пациентов с «ранними» формами рака желудка (РРЖ). Разработка надежных средств выбора объема оперативного пособия является актуальной задачей у пациентов данной категории.</p></sec><sec><title>Цель</title><p>Цель. Оценить вероятность построения устойчивой прогностической модели пациента с РРЖ для выбора метода оперативного пособия.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В работе использовались данные, полученные из оригинальной базы данных «База данных пациентов с раком желудка, отражающая статистику больных с определенным вариантом хирургического вмешательства, пролеченных в ГБУЗ ЯОКОБ за период с 2009 по 2019 г.». Все пациенты (n = 266) получили различный объем оперативного пособия: внутрипросветные операции (n = 128), клиновидные резекции желудка (n = 36), классическая гастрэктомия или субтотальная резекция желудка (n = 102). В соответствии с выполненным объемом вмешательства произведено разделение на исследуемые группы. С помощью программного обеспечения MedCalc Statistical Software version 20.022 и Statistica 12.5 произведен статистический анализ историй болезни в 3 группах больных.</p></sec><sec><title>Результаты</title><p>Результаты. Выделено 10 факторов, позволяющих сформировать модель пациента, соответствующую каждому из методов оперативного пособия. Справедливость выполненного разделения пациентов на группы проверялась при помощи ROC-анализа с целью определения чувствительности и специфичности совокупности критериев, на основе которых оно осуществляется. С помощью процедуры ROC-анализа, на ее основе мы получили следующие характеристики созданной нами математической модели: К-конкордации = 88,24 %, AUC = 0,893; индекс J = 0,811; Sе = 87,92; Sp = 89,04; +LR = 3,27; -LR = 1,31.</p></sec><sec><title>Заключение</title><p>Заключение.

The incidence of gastric cancer remains high, despite the increase in the share of stage I–II cancers — 37.1% in 2019. Surgical treatment remains relevant even in patients with “early” forms of gastric cancer (EGC). Therefore, the reliable means for determining the surgeon volume in such patients are to be urgently developed.</p></sec><sec><title>Aim</title><p>Aim. To estimate the probability of building a stable predictive model for patients with EGC in order to choose the proper surgical intervention.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Th e research involved the data obtained from “Database of patients with gastric cancer, reflecting statistics of patients with a particular variant of surgical intervention, treated at Yaroslavl Regional Clinical Oncological Hospital during the period from 2009 to 2019”. All patients (n = 266) received different volume of surgery: intraluminal surgery (n = 128), wedge gastric resection (n = 36), classical gastrectomy or subtotal gastric resection (n = 102). According to the volume of intervention, the patients were ratified into several study groups. Statistical analysis involved case records of three groups of patients and was conducted using MedCalc Statistical Soft ware version 20.022 and Statistica 12.5.</p></sec><sec><title>Results</title><p>Results. Ten factors were identified to form a patient model corresponding to each method of surgical treatment. Th e fairness of the division of patients into groups was checked by ROC-analysis in order to determine sensitivity and specificity of the set of criteria for the division. Th e following characteristics of the mathematical model were obtained by means of ROC analysis: concordance coefficient = 88.24%, AUC = 0.893; index J = 0.811; Se = 87.92; Sp = 89.04; +LR = 3.27; -LR = 1.31.</p></sec><sec><title>Conclusion</title><p>Conclusion. Introduction of this approach into clinical practice decreased the rate of gastrectomies and gastric resections by 15% for the last three years.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>персонифицированная медицина</kwd><kwd>лечебно-диагностическая тактика</kwd><kwd>дискриминантный анализ</kwd><kwd>методы хирургических операций</kwd><kwd>анализ данных пациентов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric cancer</kwd><kwd>personalized medicine</kwd><kwd>treatment and diagnostic tactics</kwd><kwd>discriminant analysis</kwd><kwd>surgical methods</kwd><kwd>patient data analysis</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">Сборник медицинской статистики.
