Проведено ретроспективное исследование непосредственных и отдаленных результатов хирургического лечения пациентов с раком желудка в ООХМЛ 5 ГБУЗ «ВОКОД» за три года. Выборка разделена на две группы: основную (50 лет и моложе) и контрольную (51 год и старше).</p></sec><sec><title>Результаты</title><p>Результаты. Из 350 пациентов, вошедших в анализ, 34 (9,71 %) были отнесены к основной группе и 316 (90,29 %) к контрольной. Заболевание у более молодых пациентов чаще протекало бессимптомно (p&lt;0,001), они чаще имели опухоли с диффузным типом роста (p=0,001). Различий в объеме хирургического лечения между группами не отмечено (p=0,613). Общая выживаемость была ниже в контрольной группе (p=0,002). Многофакторный анализ позволил установить, что прогноз для всей совокупности пациентов ухудшается при принадлежности пациентов к контрольной группе (HR=12,71), метастазах в регионарные лимфатические узлы (HR=2,64), отдаленных метастазах (HR=1,83), iii/iV стадии заболевания (HR=2,01), лимфоваскулярной (HR=3,15) и периневральной инвазии (HR=2,46), а также осложнениях после хирургического лечения (HR=2,12). Фактором, улучшающим прогноз, явилось проведение адъювантной химиотерапии (HR=0,35).</p></sec><sec><title>Выводы</title><p>Выводы. Пациенты с раком желудка моложе и старше 50 лет имеют ряд клинико-патологических особенностей, обусловливающих прогноз выживаемости.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective.

A retrospective study of surgical treatment outcomes was conducted in 350 gastric cancer patients, who were divided into 2 groups. The study group included 34 (9.71 %) patients aged 50 years and younger and the control group consisted of 316 (90.29 %) patients aged 51 years and older.</p></sec><sec><title>Results</title><p>Results. The analysis of treatment outcomes and survival rates was carried out. The diffuse-type gastric cancer was more frequently diagnosed in younger than in older patients (p&lt;0.001), and asymptomatic disease often present in younger patients (p&lt;0.001). There were no differences in the extent of surgery between the groups (p=0.613). The overall survival rate was lower in the control group than in the study group (p=0.002). The multivariate analysis revealed that a worse prognosis was observed in patients of the control group (hr=12.71), with regional lymph node metastases (hr=2.64), distant metastases (hr=1.83), iii/iv stage of the disease (hr=2.01), lymphovascular (hr=3.15) and perineural invasion (hr=2.46), as well as with postoperative complications (hr=2.12). Adjuvant chemotherapy improved the disease prognosis (hr=0.35).</p></sec><sec><title>Conclusion</title><p>Conclusion.
