Клинические стадии II и III были подтверждены у 2 (8,3%) и 22 (91,7%) больных, соответственно. В рамках комбинированного лечения проводилось 3 курса химиотерапии по схеме FOLFOX 4 с последующим хирургическим лечением. В послеоперационном периоде при T4 и N+ применялась адъювантная химиотерапия общей продолжительностью до 6 месяцев, включая время предоперационного лечения.</p></sec><sec><title>Результаты</title><p>Результаты: предоперационная химиотерапия по схеме FOLFOX 4 была завершена у всех больных. Токсичность химиотерапии составила 38,9%, нежелательные явления соответствовали I-II степени. При оценке эффекта химиотерапии (по шкале RECIST 1.1) у 18 (75%) больных отмечена частичная регрессия опухоли. Через 4 недели после завершения химиотерапии у всех больных были выполнены радикальные операции (100%). Послеоперационные осложнения развились у 4 (16,7%) больных, из них у 1 (4,2%) больного было осложнение IIIb степени (по шкале Сlavien-Dindo), что потребовало повторной операции. Полный ответ опухоли, подтвержденный морфологически (TRGl по схеме Mandard A.M.), зафиксирован у 1 (4,2%) больного. Адъювантную химиотерапию получали 13 (54,2%) больных. Медиана наблюдения за больными составила 38 (17-54) месяцев. За указанный период времени в 3 (12,5%) случаях развились местные рецидивы, в 4 (16,7%) — отдаленные метастазы. Общая и безрецидивная 3-летняя выживаемость больных достигла 91,7% и 79,2%, соответственно.</p></sec><sec><title>Заключение</title><p>Заключение: комбинированное лечение с использованием предоперационной химиотерапии по схеме FOLFOX 4 у больных раком прямой кишки с поражением верхнеампулярного отдела характеризуется хорошей переносимостью и приводит к существенной регрессии опухолевого процесса, что обеспечивает высокие показатели 3-летней выживаемости, в том числе при наличии неблагоприятных факторов прогноза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: to analyze outcomes of multimodal treatment including preoperative chemotherapy with FOLFOX 4 regimen in patients with upper rectal cancer.</p></sec><sec><title>Patients and Methods</title><p>Patients and Methods: the pilot study included 24 patients. Stages II and III were confirmed in 2 (8.3%) and 22 (91.7%) patients, respectively. All patients underwent 3 cycles of chemotherapy in FOLFOX 4 regimen followed by surgery. In the postoperative period, patients with T4 and N+ underwent adjuvant chemotherapy administered over 6 months including the time of preoperative treatment.</p></sec><sec><title>Results</title><p>Results: all patients completed preoperative chemotherapy with the FOLFOX 4 regimen. The toxicity of chemotherapy was 38.9%; adverse events did not exceed grades I-II. Partial tumor regression (RECIST 1.1 criteria) was achieved in 18 (75.0%) patients. All patients underwent surgery 4 weeks after chemotherapy. Postoperative complications occurred in 4 (16.7%) patients, 1 (4.2%) had grade IIIb complication (Clavien-Dindo scale), which required re-surgery. Pathological complete response (TRG1 by Mandard scale) was revealed in 1 (4.2%) patient. Thirteen patients (54.2%) received adjuvant chemotherapy. The mean follow-up was 38 (17-54) months. Three patients (12.5%) developed local recurrence and 4 (16.7%) patients — distant metastases. The 3-year overall and diseasefree survival rates were 91.7% и 79.2%, respectively.</p></sec><sec><title>Conclusion</title><p>Conclusion: multimodal treatment including preoperative chemotherapy with the FOLFOX 4 regimen was well tolerated and produced tumor regression with high 3-year survival rates in patients with upper rectal cancer.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак прямой кишки</kwd><kwd>предоперационная химиотерапия</kwd><kwd>токсичность</kwd><kwd>патоморфоз</kwd><kwd>выживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rectal cancer</kwd><kwd>preoperative chemotherapy</kwd><kwd>toxicity</kwd><kwd>pathomorphosis</kwd><kwd>survival</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">Oronsky B, Reid T, Larson C, et al.
