The study included 1593 patients, of whom 720 were men (45.2 %) and 873 women (54.8 %). Patients were divided into 3 age groups: under 50 years, 50–70 years and over 70. Overall survival rates were calculated, followed by comparison between groups of patients, taking into account gender and stage of the disease.</p><p><bold>Results</bold>. Analysis of treatment results taking into account a gender approach showed that the prognosis of the disease was most favorable in women. With approximately the same 5-year survival rate in men and women (54.9 and 52.7 %), this indicator correlated with the age of the patients and was significantly better than in men in the group of patients under 50 years of age.</p><p><bold>Conclusion</bold>. The identified gender and age characteristics in the development and course of colorectal cancer are relevant for oncologists when choosing diagnostic, treatment and rehabilitation strategies. </p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Исследования последних лет приводят к выводу о значимости пола как важного фактора, влияющего на прогноз выживания больных колоректальным раком (КРР).</p><p><bold>Цель исследования</bold> – анализ показателей 5-летней общей выживаемости больных КРР разного пола и в различных возрастных группах.</p><p><bold>Материалы и методы</bold>. В исследование включено 1 593 пациента, из них 720 (45,2 %) мужчин и 873 (54,8 %) женщины. Больных разделили на 3 возрастные группы: до 50 лет, 50–70 лет и старше 70 лет. Проводился подсчет общей выживаемости с последующим сравнением между группами пациентов с учетом пола и стадий заболевания.</p><p><bold>Результаты</bold>. Анализ результатов лечения с учетом гендерного подхода показал, что прогноз заболевания наиболее благоприятен у женщин. При практически одинаковой 5-летней выживаемости у мужчин и женщин (54,9 и 52,7 % соответственно) этот показатель коррелировал с возрастом пациентов и был достоверно лучше, чем у мужчин в группе больных моложе 50 лет.</p><p><bold>Заключение</bold>. Выявленные гендерные и возрастные особенности в развитии и течении КРР актуальны для онкологов при выборе диагностических, лечебных и реабилитационных стратегий. </p></trans-abstract><kwd-group xml:lang="en"><kwd>colorectal cancer</kwd><kwd>gender</kwd><kwd>long-term treatment results</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>колоректальный рак</kwd><kwd>гендер</kwd><kwd>отдаленные результаты лечения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sung H., Ferlay J., Siegel R.L. et al.
