This study included 677patients that underwent emergency surgeries for complicated colorectal cancer in 3 hospitals for general surgery in Smolensk over the last 13 years. Severity of postoperative complications was graded using the Clavien—Dindo classification. The length of follow-up varied between 0 and 60 months. Kaplan—Meier survival curves were constructed to assess relapse-free and overall survival. The Cox proportional regression model was used to estimate the risk factors for survival.</p><p><bold>Results.</bold> The main risk factors affecting short-term treatment outcomes were the severity of the overall condition (grave and critical) and time from symptom onset to hospital admission (&gt;24 h). Using univariate and multivariate analysis, we identified independent prognostic factors associated with poorer 5-year relapse-free survival. They included presence of cancer cells at the resection margin (R1 resection) (hazard ratio (HR) 1.36; 95 % confidence interval (CI) 1.284—1.450; p &lt;0.0001), rectal tumor (HR 1.085; 95 % CI 0.974—1.209; p = 0.009), and one-stage surgery (HR 1.141; 95 % CI 1.034—1.259;p &lt;0.0001).</p><p><bold>Conclusions.</bold> Positive resection margin (R1 resection) was an independent prognostic factor associated with poorer overall and relapse-free survival in patients with complicated colorectal cancer.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> — изучить результаты экстренных хирургических вмешательств по поводу осложненного колоректального рака в общехирургических стационарах, оценив факторы риска и их влияние на непосредственные и отдаленные результаты лечения.</p><p><bold>Материалы и методы.</bold> Исследование основано на анализе результатов лечения 677больных, перенесших экстренные хирургические вмешательства по поводу осложненного колоректального рака в 3 общехирургических стационарах г. Смоленска за период 13 лет. Послеоперационные осложнения оценивали по классификации Clavien—Dindo. Продолжительность наблюдения больных составила от 0 до 60мес. Безрецидивную и общую выживаемость анализировали методом Kaplan—Мeier. Для определения влияния потенциальных факторов риска на скорость наступления изучаемого события использовали регрессию Кокса. Результаты. Основными факторами риска, влияющими на непосредственные результаты лечения, стали тяжесть общего состояния больного (тяжелое, крайне тяжелое), время обращения с момента развития заболевания (&gt;24 ч). Путем однофакторного, а в последующем многофакторного анализа определены независимые прогностические факторы, неблагоприятно влияющие на 5-летнюю безрецидивную выживаемость: наличие опухолевого роста по линиям резекции (Я1-резекции) (отношение рисков (ОР) 1,36; 95 % доверительный интервал (ДИ) 1,284—1,450;p &lt;0,0001); локализация опухоли в прямой кишке (ОР 1,085; 95 % ДИ 0,974—1,209; p = 0,009); одноэтапные оперативные вмешательства (ОР 1,141; 95 % ДИ 1,034—1,259; p &lt;0,0001).</p><p><bold>Выводы.</bold> Выполнение R1-резекций явилось независимым прогностическим фактором общей и безрецидивной выживаемости у пациентов с осложненным колоректальным раком.</p></trans-abstract><kwd-group xml:lang="en"><kwd>complicated colorectal cancer</kwd><kwd>emergency surgery</kwd><kwd>prognostic factors</kwd><kwd>survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>осложненный колоректальный рак</kwd><kwd>экстренные операции</kwd><kwd>прогностические факторы</kwd><kwd>выживаемость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Khan M.A., Hakeem A.R., Scott N. et al.
