Так как основным методом лечения распространённых форм опухоли является лекарственный, сохраняется необходимость разработки и внедрения в клиническую практику новых эффективных методов химиотерапии колоректального рака. В данной статье представлен промежуточный анализ лечения пациентов с диссеминированным колоректальным раком, проходивших лечение в УЗ «МГКОД» в 2016–2019 гг., с использованием метрономной поддерживающей химиотерапии (n = 60). Метрономный режим включал в себя приём капецитабина 500 мг 3 раза в день и циклофосфана 50 мг ежедневно. Медиана времени наблюдения за пациентами составила 18,5 мес. Медиана времени, свободного от прогрессирования, составила 9,0 и 7,4 мес. в исследуемой и контрольной группах соответственно. Медиана общей выживаемости, рассчитанная от момента начала индукционной химиотерапии, в настоящий момент составляет 22,9 мес. в группе поддерживающей химиотерапии и 14,7 мес. в группе контроля. Контрольная группа состояла из пациентов с диссеминированным колоректальным раком, получавших такую же индукционную химиотерапию (FolFox или Xelox), без поддерживающего лечения в период с 2011-ого по 2015-ый год (n = 70). Факторами прогноза чувствительности к метрономной химиотерапии у пациентов с колоректальным раком являются низкие уровни экспрессии генов TS, DPD и VEGFR1, высокий уровень экспрессии гена TP, низкий уровень маркеров РЭА, СА 19-9. На основании этих данных может быть выделена группа пациентов, которым рекомендовано применение данного метода лечения.</p></abstract><trans-abstract xml:lang="en"><p>The treatment of colorectal cancer is one of the most challenging problems of modern oncology due to the high incidence both in the Republic of Belarus and in the whole world. Since chemotherapy remains the main method of treatment of metastatic disease, there remains a need to develop and introduce into clinical practice new effective methods of chemotherapy for colorectal cancer. This article presents the interim results of treatment of colorectal cancer patients in Minsk City Clinical Oncologic Dispensary with the use of maintenance metronomic chemotherapy, who were enrolled from 2016 till 2019 (n = 60). Metronomic regimen consisted of oral capecitabine 500 mg 3 times a day and oral cyclophosphane 50 mg daily. The control arm consisted of mCRC patients who received the same induction chemotherapy without maintenance from 2011 till 2015 (n = 70). Median follow-up time was 18,5 months. Median progression-free survival (PFS) was 9.0 and 7.4 months in the maintenance and control arms respectively. Median overall survival (OS), counted from the beginning of induction chemotherapy, is currently 22.9 months in the maintenance arm, and 14.7 months in control. Low expression levels of genes, encoding enzymes TS (thymidylate synthetase), DPD (dihydropyrimidine dehydrogenase) and receptor VEGFR1, high expression level of gene TP (thymidylate phosphorylase), as well as low levels of tumor markers CEA and СА 19-9 are the prognostic factors of sensitivity to metronomic chemotherapy given to colorectal cancer patients. Based on these data, we identified a group of patients who are recommended to use this method of treatment.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метрономная химиотерапия</kwd><kwd>колоректальный рак</kwd><kwd>факторы чувствительности</kwd><kwd>опухолевые маркеры</kwd><kwd>полиморфизм генов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metronomic chemotherapy</kwd><kwd>colorectal cancer</kwd><kwd>factors of sensitivity</kwd><kwd>tumor markers</kwd><kwd>gene polymorphism</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">Океанов, А.
