Материал и методы. С 2018 по 2021 г. в МРНЦ им. А.Ф. Цыба проходило исследование II фазы, которое включало 47 пациентов с морфологически верифицированным местнораспространенным раком желудка, стадированных по классификации сTNM как сT3/Т4а–b – 26/21; сN0/N1–3 – 20/27. Верхняя треть желудка была поражена у 19 больных (у 9 с распространением на пищевод), средняя треть – у 13, нижняя треть – у 14, тотальное поражение – у 1 пациента. Аденокарцинома G3 диагностирована у 23, G2 – у 13, G1 – у 7, перстневидно клеточный рак – у 4 больных. Программа лечения заключалась в проведении 2 циклов индукционной химиотерапии по схеме FLOT (оксалиплатин 85 мг/м2 + кальция фолинат 200 мг/м2 + доцетаксел 50 мг/м2 в 1-й день + фторурацил 2600 мг/м2 24-часовая инфузия с 1-го дня; 1 раз в 2 нед). В последующем проводили курс 3d-конформной дистанционной лучевой терапии (РОД 2 Гр, до СОД 46 Гр) на фоне химиотерапии капецитабином и оксалиплатином. Далее выполнялось контрольное обследование пациента с целью исключения прогрессирования опухоли и планировался хирургический этап лечения. Оценка послеоперационных осложнений проводилась согласно классификации Clavien–dindo. Результаты. Неоадъювантная химиолучевая терапия после индукционных циклов сопровождается удовлетворительной переносимостью. К хирургическому этапу лечения в срок приступило 45 (95,7 %) больных, радикальные операции которым были выполнены в 97,7 % случаев. Послеоперационные осложнения отмечены у 11 (23,4 %) пациентов, при этом осложнения III степени и выше – в 3 (6,4 %) случаях. Послеоперационная летальность имела низкие показатели и составила 2,2 % (n=1). Заключение. Предложенная методика индукционной полихимиотерапии по схеме FLOT с химиолучевым компонентом комбинированного лечения удовлетворительно переносится больными, воспроизводима в полном объеме у абсолютного большинства пациентов, не уменьшает частоты R0-резекций и не увеличивает частоту послеоперационных осложнений.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to analyze of the safety and feasibility of neoadjuvant chemotherapy (2 cycles of FLOT chemotherapy + chemoradiotherapy) followed by surgery in the treatment of locally advanced gastric cancer. Material and Methods. The phase II clinical trial included 47 patients with histologically verified locally advanced gastric cancer (cT3/T4a-b: 26/21 and cN0/N1–3: 20/27) treated at the A.F. Tsyba MRRC from 2018 to 2021. Lesion location was: upper third in 19 patients (esophageal invasion in 9 patients), middle third in 13 patients, lower third in 14 patients, and entire stomach in 1 patient. The tumor grade was G3 in 23 patients, G2 in 13 patients and G1 in 7 patients. Signet ring cell carcinoma was revealed in 4 patients. The patients received 2 cycles of induction chemotherapy with FLOT regimen (85 mg/m2 oxaliplatin + 200 mg/m2 calcium folinate + 50 mg/m2 docetaxel on day 1 + 2600 mg/m2 fluorouracil as 24-hour infusion from day 1; every 2 weeks) followed by 3d-conformal external beam radiotherapy (46 Gy in daily fractions of 2 Gy) combined with chemotherapy with capecitabine and oxaliplatin). The patients then underwent follow-up examination to exclude disease progression and to plan surgery. Postoperative complications were analyzed using the Clavien-dindo classification. Results. Induction chemotherapy followed by concurrent chemoradiotherapy was well tolerated. Forty-five (95.7 %) patients underwent surgery, 97.7 % of them underwent radical surgery. Postoperative complications were observed in 11 (23.4 %) patients. Grade III and more severe complications were observed in 3 (6.4 %) patients. It should be noted that postoperative mortality rate was low, amounting to 2.2 % (1 patient). Conclusion. Induction FLOT polychemotherapy followed by concurrent chemoradiotherapy was shown to be safe, feasible, and tolerable. Moreover, this treatment regimen did not reduce the frequency of R0 surgeries and did not increase incidence and severity of postoperative complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>неоадъювантная химиотерапия</kwd><kwd>неоадъювантная химиолучевая терапия</kwd><kwd>токсичность</kwd><kwd>хирургическое лечение</kwd><kwd>послеоперационные осложнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric cancer</kwd><kwd>neoadjuvant chemotherapy</kwd><kwd>neoadjuvant chemoradiotherapy</kwd><kwd>toxicity</kwd><kwd>surgical treatment</kwd><kwd>postoperative complications</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">Sung H., Ferlay J., Siegel R.L., Laversanne M., Soerjomataram I., Jemal A., Bray F.
