Показано, что в предоперационном периоде большинство больных получает запланированное лечение в полном объеме, при этом проведенная химиотерапия не оказывает негативного влияния на течение послеоперационного периода. Однако адъювантные курсы химиотерапии завершает примерно 60 % pадикально прооперированных больных. В связи с чем обсуждается вопрос о переносе всех курсов химиотерапии при резектабельном РЖ на предоперационный период.</p><p>Целью исследования явилось изучение непосредственной эффективности и токсичности тотальной неоадъювантной химиотерапии по модифицированной схеме Flot у больных с резектабельным РЖ.</p><sec><title>Материал и методы</title><p>Материал и методы. В НИИ онкологии Томского НИМЦ с 2020 г. проводится пилотное исследование, в которое включено 25 больных резектабельным раком желудка сt2–4N0–2m0, получавших 8 курсов неоадъювантной химиотерапии по схеме FloТ c последующей радикальной операцией в объеме гастрэктомии или дистальной субтотальной резекции желудка.</p></sec><sec><title>Результаты</title><p>Результаты. Предоперационная химиотерапия в запланированном объеме завершена у 25 (100 %) больных. Токсические реакции, возникшие в процессе химиотерапии, не требовали отмены или перерыва в лечении, редукции первоначальной дозы цитостатиков, наиболее частыми нежелательными явлениями являлись эметогенные реакции (92 %), периферическая нейропатия (60 %), нейтропения (48 %), во всех случаях нежелательные явления были i–ii степени и купировались стандартной терапией сопровождения. Радикальные операции в среднем выполнялись через 6 нед после завершения 8-го курса химиотерапии. Не наблюдалось значимых послеоперационных осложнений (iii степени и выше по шкале clavien–dindo) и летальных исходов. По данным патоморфологического исследования операционного материала был выявлен лечебный патоморфоз tRg2–3 степени у 21 (84 %) больного, снижение клинической стадии по индексу t и N («downstaging») отмечено у 13 (52 %) больных.</p></sec><sec><title>Заключение</title><p>Заключение. Тотальная неоадъювантная химиотерапия в режиме 8 курсов по схеме Flot при резектабельном раке желудка демонстрирует высокую непосредственную эффективность, умеренную контролируемую токсичность, не оказывая отрицательного влияния на течение периоперационного периода.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Currently, perioperative chemotherapy is the standard treatment option for resectable gastric cancer (GC ) at stages higher than T1. Preoperative chemotherapy was shown do not adversely affect the course of the postoperative period in gastric cancer patients. However, approximately 60 % of radically operated patients complete adjuvant chemotherapy. In this regard, the problem arises of postponing all courses of chemotherapy for operable gastric cancer to the preoperative period.</p><p>The purpose of the study was to analyze short-term efficacy and toxicity of total neoadjuvant chemotherapy with FLOT regimen in patients with resectable gastric cancer.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. Since 2020, the Research Cancer Institute of Tomsk National Research Medical Center has been conducting a pilot study, which included 25 patients with resectable gastric cancer (T2–4N0–2M0) who received 8 cycles of neoadjuvant chemotherapy with FLOT regimen followed by radical surgery (gastrectomy or distal subtotal resection of the stomach).</p></sec><sec><title>Results</title><p>Results. Preoperative chemotherapy was completed in 25 (100 %) patients. Side effects that occurred during chemotherapy did not require cancellation or interruption of treatment and reduction in the initial dose of drugs. The most common adverse events were emetogenic reactions (92 %), peripheral neuropathy (60 %), and neutropenia (48 %). All patients had no greater than grade II toxicity, which was reversed with standard maintenance therapy. Radical surgeries were performed 6 weeks after completion of chemotherapy cycle 8. There were no significant postoperative complications (grade III or higher according to the Clavien–Dindo scale) and deaths. The histological examination revealed pathological response of TG R2–3 grade in 21 (84%) patients. Downstaging in both T and N categories was found in 13 (52%) patients.</p></sec><sec><title>Conclusion</title><p>Conclusion. Eight cycles of total neoadjuvant chemotherapy for resectable gastric cancer demonstrates high efficacy, moderate toxicity, and do not adversely affect the course of the perioperative period.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>резектабельный рак желудка</kwd><kwd>комбинированное лечение</kwd><kwd>тотальная неоадъювантная химиотерапия</kwd><kwd>токсичность</kwd><kwd>непосредственная эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>resectable gastric cancer</kwd><kwd>multimodality combined treatment</kwd><kwd>total neoadjuvant chemotherapy</kwd><kwd>toxicity</kwd><kwd>short-term efficacy</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">Bray F., Ferlay J., Soerjomataram I., Siegel R.L., Torre L.A., Jemal A.
