Оценка влияния включения препарата лактоглобулина в комплекс предоперационной подготовки больных раком ободочной кишки на состав микробиоты опухоли и ткани, взятой по линии резекции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. 40 больным раком ободочной кишки II–III стадий, у которых операция была первым этапом лечения, в курсе стандартной предоперационной подготовки вводили препарат антител против условно-патогенных микроорганизмов кишечника, полученный из молозива иммунизированных коров, по 2 г 2 раза в день перорально перед операцией в течение 3-х дней (суммарная доза 12 г) (основная группа); 40 больных получали стандартную антибиотикопрофилактику (контрольная группа). В образцах удаленной опухоли и ткани линии резекции определяли количественный состав микробиоты.</p></sec><sec><title>Результаты</title><p>Результаты. У больных основной группы общая микробная обсемененность опухоли была в 9,2 раза ниже контрольной; частота выделения E.сoli и Clostridiae была также статистически значимо ниже (р = 0,004 и 0,03 соответственно). В опухолях больных основной группы из двенадцати исследованных представителей микроорганизмов количество шести было статистически значимо ниже контроля, а три из обнаруженных в контрольной группе не выявлялись. Поскольку они относились к потенциально патогенным (Pseudomonas aeruginosa, Staphylococcus aureus, грибы рода Сandida), микробный состав опухоли больных основной группы можно считать более благоприятным, чем контрольной. Подобные различия отмечены и в неопухолевой ткани кишки, в которой содержание Enterobacter spp, Streptcocci, Clostridiae, Peptostreptococci было статистически значимо ниже, чем в контроле.</p></sec><sec><title>Заключение</title><p>Заключение. Итак, пероральное применение антительного препарата лактоглобулина вызывает положительные изменения микробиоты опухоли и неопухолевой ткани кишки. Учитывая возможное влияние состава микробиоты на ответ больного на дальнейшую химио- и иммунотерапию, считаем целесообразным использование препарата для подготовки к адъювантному лечению.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To assess the effect of inclusion of lactoglobulin in complex preoperative preparation of colon cancer patients on their tumor and resection line tissue microbiota.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 40 patients with colon cancer stages II–III, in whom the operation was the first stage of treatment, during standard preoperative preparation, were injected with a preparation of antibodies against opportunistic intestinal microorganisms obtained from colostrum of immunized cows, 2 g twice a day orally before surgery for 3 days (total dose of 12 g) (main group); 40 patients received standard antibiotic prophylaxis (control group). The quantitative composition of the microbiota was determined in the samples of the removed tumor and tissue of the resection line.</p></sec><sec><title>Results</title><p>Results. The total microbial contamination of the tumor was 9.2 times lower in the main group relative to the control group; the frequency of E.coli and Clostridiae excretion was also statistically significantly lower (p = 0.004 and 0.03, respectively). In the tumors of patients of the main group out of twelve studied representatives of microorganisms, the number of six was statistically significantly lower than in control group, and three of those found in the control group were not detected. Since they were potentially pathogenic (Pseudomonas aeruginosa, Staphylococcus aureus, fungi of the Candida spp.), the microbial composition of the tumor of patients in the main group can be considered more favorable than the control group. Similar differences were noted in non-t umor intestinal tissue, in which the content of Enterobacter spp, Streptococcus, Clostridiae, Peptostreptococci was statistically significantly lower than in the control group.</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus oral administration of colostrum antibodies caused positive changes in tumor and colon tissue microbiota. We suggest the application of lactoglobulin to be useful for surgical treatment of such patients taking into account the possible impact of microbiota in patients’ response to chemo- and immunotherapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак ободочной кишки</kwd><kwd>микробиота опухоли и интактной ткани кишечника</kwd><kwd>лактоглобулин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colon cancer</kwd><kwd>tissue microbiota</kwd><kwd>tumor and intact colon tissue</kwd><kwd>lactoglobulin</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">Abreu MT, Peek RM.
