ПАЦИЕНТЫ И МЕТОДЫ: обследовано 27 пациентов с КРР; у 10 пациентов перитонеальный лаваж выполнен перед и после ВБГХТ. Лаважную жидкость подвергали многостадийной процедуре очистки от фибрина; сконцентрированные клетки окрашивали антителами CD133 VioBright-FITCCD24 PE, CD26 ECD, CD184 PC5 и CD44 PC7 и выполняли проточную цитометрию. РЕЗУЛЬТАТЫ: выявлено повышение экспрессии CD133 (p&lt;0,001) и CD184 (p&lt;0,05) в группе больных с опухолями ободочной кишки. Вовлечение брыжеечных лимфоузлов характеризовалось увеличением экспрессии CD26 (p&lt;0,05). Соотношение экспрессии CD44 / CD26 (p&lt;0,05) было повышено у пациентов с карциноматозом брюшины. Под действием ВБХТ падает экспрессия CD24 у опухолевых стволовых клетках. ЗАКЛЮЧЕНИЕ: предложенный способ выделения и оценки свободных перитонеальных клеток КРР пригоден для применения в клинической практике, в частности, для оценки эффективности ВБГХТ. Показано подавляющее действие ВБГХТ на раковые стволовые клетки.</p></abstract><trans-abstract xml:lang="en"><p>AIM: to test a method of free intraperitoneal colorectal cancer (CRC) cells isolation for the immunophenotyping and evaluation of mitomycin C hypertermic intraabdominal chemotherapy (HICT) PATIENTS AND METHODS: twenty-seven patients with CRC were included in the study.Peritoneal lavage prior and after HICT was performed for 10 of them. We defibrinated lavage fluid and stained concentrated tumour cells with monoclonal antibodies CD133 Vio Bright - FITC, CD24 PE, CD26 ECD, CD184 PC5 and CD44 PC7. FACS analysis was done after staining. RESULTS: patients with colon cancers had the increased expression of CD133 (p&lt;0.001) and CD184 (p&lt;0.05). Mesenteric lymph nodes involvement was followed by an increase of CD26 expression (p&lt;0.05) in CD133+ cancer cells. The ratio of CD44/CD26 expression was increased in patients with peritoneal carcinomatosis (p&lt;0.05). HICT lowers CD24 expression on CD133+ cancer stem cells. CONCLUSION: the method proposed for free peritoneal CRC cells identification and phenotyping can be used in clinical practice, particularly for evaluating the HICT efficacy. Suppressive effect of HICT on cancer stem cells is detected.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>перитонеальный карциноматоз</kwd><kwd>опухолевые стволовые клетки</kwd><kwd>внутрибрюшинная химиотерапия</kwd><kwd>фибрин</kwd><kwd>трипсин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>peritoneal carcinomatosis</kwd><kwd>cancer stem cells</kwd><kwd>intraperitoneal chemotherapy</kwd><kwd>fibrin</kwd><kwd>trypsin</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">Rathore, R.
