Современным стандартом радикального лечения местнораспространенного рака желудка (мРЖ) является комбинация радикального хирургического лечения и адъювантной полихимиотерапии (АПХТ). Это не позволяет предупредить развитие метахронной перитонеальной диссеминации (МПД), особенно при инфильтративных формах мРЖ, что диктует необходимость дополнения существующего стандарта интраперитонеальной химиотерапией (ИХТ).</p></sec><sec><title>Цель</title><p>Цель. Оценить показатели выживаемости и кумулятивную инцидентность прогрессирования мРЖ рТ1-4N1-3M0 после применения нормотермической ИХТ и системной АПХТ по схеме капецитабин/оксалиплатин.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проанализированы отдаленные результаты лечения 341 радикально оперированного по поводу мРЖ пациента (pT1-4N1-3M0, III-IV тип по R.Bormann). В качестве адъювантного лечения использованы: нормотермическая ИХТ цисплатином, АПХТ (капецитабин/оксалиплатин). Для оценки отдаленных результатов лечения использованы метод множительных оценок Каплана-Мейера, анализ конкурирующих рисков с оценкой кумулятивной инцидентности (КИ) прогрессирования, в том числе МПД. Для оценки влияния ИХТ и АПХТ на риск развития прогрессирования опухолевого процесса (МПД, отдаленных лимфогематогенных метастазов (ОЛГМ) и их сочетания) использовали модель Файна–Грея.</p></sec><sec><title>Результаты</title><p>Результаты. Применение нормотермической ИХТ и АПХТ сопровождалось снижением:</p><p>1) 3-летней КИ прогрессирования опухолевого процесса в сравнении с хирургическим лечением (59,7±3,1%), составив после каждого из вышеприведенных вариантов лечения соответственно 48,3±9,6% и 37,0±6,9% (рGray = 0,001); 2) 3-летней КИ МПД (в изолированном варианте) в сравнении с хирургическим лечением (32,0±3,0%) – 17,2±7,2% и 7,7±3,8% (рGray &lt; 0,001). Проведение как нормотермической ИХТ, так и АПХТ снижает риск развития МПД (в изолированном варианте) в сравнении с хирургическим лечением – ОР 0,31 (95% ДИ 0,12–0,80), р = 0,016 и ОР 0,17 (95% ДИ 0,06–0,47), р &lt; 0,001, не влияя на риск развития ОЛГМ и комбинации МПД+ОЛГМ (р &gt; 0,05).</p></sec><sec><title>Вывод</title><p>Вывод. Возможность предупреждения МПД после проведения системной АПХТ и нормотермической ИХТ определяет необходимость учета объема лекарственного лечения при оценке вероятности развития МПД после радикального лечения мРЖ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The currently used standard of radically treating locally advanced gastric cancer (lGC) employs a combination of radical surgery and adjuvant polychemotherapy (APCT) that cannot prevent metachronous peritoneal dissemination (MPD), especially when treating infiltrative lGC. Therefore, it needs to be supplemented by intraperitoneal chemotherapy (ICT).</p></sec><sec><title>Objectives</title><p>Objectives. Evaluating survival rates and cumulative incidence of рТ1-4N1-3M0 lGC after administering normothermic ICT and systemic capecitabine/oxaliplatin APCT.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Long-term results of radical surgery performed on 341 lGC patients (pT1-4N1-3M0, type III-IV on the R. Borrmann scale) were analyzed. The adjuvant treatment comprised cisplatin-based normothermic ICT and capecitabine/oxaliplatin APCT. Long-term treatment results were analyzed by means of the Kaplan-Meyer multiplier estimation method, competing risks analysis to evaluate cumulative incidence (CI) of progression including that of MPD. The Fine-Gray model was used to assess the effect of ICT and APCT on the risks of tumor progression (MPD, distant lymphohematogenous metastases (RLHM) and their combinations).</p></sec><sec><title>Results</title><p>Results. The application of normothermic ICT and APCT resulted in the decrease (1) in the 3-year CI of tumor progression in comparison to surgical treatment alone (59.7±3.1%), scoring after each of these procedures 48.3±9.6% and 37±6.9%, respectively, (рGray = 0.001); (2) in the 3-year MPD CI (in an isolated variant) in comparison to surgical treatment alone – (32.0±3.0%) – 17.2±7.2% и 7.7±3.8% (рGray &lt; 0.001). Both normothermic ICT and APCT reduce the risk of developing MPD (in an isolated variant) in comparison to surgical treatment – HR 0.31 (95% confidence interval 0.12–0.80), р = 0.016and HR 0.17 (95% confidence interval 0.06–0.47), р &lt; 0.001, without effecting RLHM and combined MPD+RLGM development risks (р &gt; 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. The possibility of preventing MPD after administering systemic APCT and normothermic ICT highlights the importance of accounting the extent of drug therapy in evaluating the probability of MPD development after lGC radical surgery.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак желудка</kwd><kwd>интраоперационная интраперитонеальная химиотерапия</kwd><kwd>адъювантная системная полихимиотерапия</kwd><kwd>метахронная перитонеальная диссеминация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric cancer</kwd><kwd>intraperitoneal chemotherapy</kwd><kwd>adjuvant systemic polychemotherapy</kwd><kwd>metachronous peritoneal dissemination</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">Алгоритмы диагностики и лечения больных злокачественными новообразованиями / Ю.И.
