Материалы и методы: в исследование включено 70 больных с плоскоклеточным раком пищевода II-III стадии. Основную группу составили 35 больные, которые получали 2 курса предоперационной химиотерапии, а после проводилось радикальное оперативное вмешательство, в контрольную группу входили 35 больные, которым проведено только хирургическое лечение. Проанализированы двухлетние результаты. Результаты: комбинированное лечение с использованием предоперационной химиотерапии по схеме гемцитабин/цисплатин переносится удовлетворительно. В результате проведения комбинированного лечения в основной группе 2-летняя безрецидивная выживаемость больных РП II-III стадии составила 71,8%, в контрольной группе - 39,4% (р&lt;0,05). Общая 2-летняя выживаемость больных в основной группе составила 81,3%, в контрольной группе при проведении хирургического лечения - 51,5% (р&lt;0,05). Заключение: комбинированное лечение рака пищевода II-III стадии с использованием предоперационной ХТ по схеме гемцитабин/цисплатин достоверно снижает частоту местных рецидивов и отдаленных метастазов, повышает 2-летнюю выживаемость больных раком пищевода II-III стадии относительно только хирургического лечения, в том числе при наличии таких неблагоприятных прогностических факторов как метастатическое поражение регионарных лимфоузлов (N+) и высокоагрессивные формы (G3) плоскоклеточного рака.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the study was to analyze efficacy and tolerability of combined modality treatment including preoperative chemotherapy with gemcitabine/cisplatin in patients with stage II-III esophageal squamous cell carcinoma. Materials and methods. The study included 70 patients with stage II-III esophageal squamous cell carcinoma. All patients were divided into two groups. Group I (study group) consisted of 35 patients, who received 2 courses of preoperative chemotherapy followed by radical surgery. Group II (control group) comprised 35 patients who underwent surgery alone. The 2-year survival rates were analyzed. Results. Combined modality treatment including preoperative chemotherapy with gemcitabine/cisplatin was well tolerated. The 2-year disease-free survival rates were 71.8% and 39.4% in groups I and II, respectively (р&lt;0.05). The overall 2-year survival rate was 81.3% in patients who received chemotherapy followed by surgery and 51.5% in patients who underwent surgery alone (р&lt;0.05). Conclusion. Compared to surgery alone, combined modality treatment including preoperative chemotherapy with gemcitabine/cisplatin significantly reduced the frequency of local recurrence and distant metastases and increased 2-year survival rate in patients with stage II-III esophageal squamous cell carcinoma, including the presence of unfavorable prognostic factors, such as regional lymph node metastases (N+) and high-grade (G3) squamous cell carcinoma.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>плоскоклеточный рак пищевода</kwd><kwd>комбинированное лечение</kwd><kwd>предоперационная химиотерапия</kwd><kwd>лечебный патоморфоз</kwd><kwd>непосредственные и отдаленные результаты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>esophageal squamous cell carcinoma</kwd><kwd>combined modality treatment</kwd><kwd>preoperative chemotherapy</kwd><kwd>pathological response</kwd><kwd>short-and long-term treatment outcomes</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">Urmonov U.B., Dobrodeev A.
