Материалы и методы. В исследование включены 64 пациента с первичными ретроперитонеальными саркомами с вовлечением почки и структур почечной ножки, проходивших хирургическое лечение в торакоабдоминальном отделении МНИОИ им. П.А. Герцена (2010–2021). Нефрэктомии выполнены у 21 больного, у 43 больных применены нефронсберегающие технологии. Изучен морфологический профиль сарком, половозрастной состав, возможности нефронсберегающих технологий, частота послеоперационных осложнений в обеих группах, а также отдаленные результаты лечения, в том числе в зависимости от различных факторов. С этой целью проведен многофакторный анализ. Результаты. У 43 больных с первичными ретроперитонеальными саркомами с вовлечением в опухолевый процесс почки, мочеточника, сосудистой ножки почки операции выполнялись с применением нефронсберегающих технологий: прецизионное выделение почки, мочеточника и сосудистых структур почки из опухолевых узлов, резекция почки, стентирование мочеточника, резекция устьев почечных вен, резекция мочеточников, аутотрансплантация почки. Послеоперационные осложнения: группа нефрэктомий – 19,0 % (4 пациента, типы II, IIIB, IV и V по Clavien–Dindo), группа нефронсберегающих операций – 30,2 % (13 пациентов: типы II – 8, IIIA – 1, IIIB – 3, IV – 1); летальных исходов не было. При статистическом анализе групп нефрэктомий и нефронсберегающих операций безрецидивный период и выживаемость статистически не отличались. Однолетняя выживаемость во всей группе составила 84,1 %, 3-летняя – 65,9 %, 5-летняя – 51,4 %. При мультифакторном анализе достоверно повышается смертность у пациентов старше 64 лет, связанная как с рецидивом процесса, так и наличием сопутствующей патологии (p=0,009). Также выявлена тенденция к уменьшению выживаемости у больных лейомиосаркомой (р=0,066). Выводы. При ретроперитонеальных саркомах рациональной хирургической тактикой представляется удаление опухоли с сохранением органов и структур, не вовлеченных непосредственно в опухолевый процесс. Нефронсберегающие технологии не ухудшают как непосредственные, так и отдаленные результаты лечения. При лейомиосаркомах более целесообразным является удаление опухоли с нефрэктомией.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to clarify the indications for the use of nephron-sparing technologies in surgical treatment of patients with retroperitoneal sarcomas. Material and Methods. The study included 64 patients with primary retroperitoneal sarcomas with kidney and renal pedicle invasion, who underwent surgical treatment in the Thoracic-abdominal Department of the P.A. Herzen Moscow Oncology Research Institute from 2010 to 2021. Twenty-one patients underwent nephrectomies, and 43 patients underwent nephron-sparing surgery. The morphological profile of sarcomas, age and gender of the patients, feasibility of using nephron-sparing technologies, postoperative complications, and long-term outcomes in patients of both groups were analyzed. Results. Forty-three patients with primary retroperitoneal sarcomas with invasion of the renal parenchyma, ureter, and renal pedicle underwent nephron-sparing surgery (precision mobilization of the kidney, ureter and vascular structures of the kidney from tumor tissue, kidney resection, ureteral stenting, resection of the renal vein orifices, resection of the ureters, and kidney autotransplantation). Postoperative complications were observed in 19.0 % of nephrectomy group patients (4 pts: II, IIIB, IV and V types according to Clavien–Dindo) and in 30.2 % of nephron-sparing group patients (15 pts: types II – 8, IIIA – 1, IIIB – 3, IV – 1). No statistical differences in the relapse-free period and survival time between two groups were observed. The 1-, 3- and 5-year survival rates were 84.1 %, 65.9 %, and 51.4 %, respectively. Multifactorial analysis showed that mortality increased significantly in patients over 64 years of age and was associated with both disease recurrence and concomitant pathology (p=0.009). There was also a trend toward decreased survival in patients with leiomyosarcoma (p=0.066). Conclusion. In retroperitoneal sarcomas, tumor resection with preservation of organs and structures not directly invaded by the tumor is the optimal surgical strategy. Nephron-sparing technologies do not worsen both immediate and long-term treatment outcomes. For leiomyosarcoma, tumor resection with nephrectomy is the most suitable approach.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>неорганные забрюшинные комплексы</kwd><kwd>ретроперитонеальные саркомы</kwd><kwd>нефронсберегающие операции</kwd><kwd>липосаркома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>retroperitoneal neoplasm/surgery</kwd><kwd>liposarcomas</kwd><kwd>nephron surgery</kwd><kwd>disease progression</kwd><kwd>nephrectomy</kwd><kwd>nephron-sparing resection</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">Toulmonde M., Bonvalot S., Ray-Coquard I., Stoeckle E., Riou O., Isambert N., Bompas E., Penel N., Delcambre-Lair C., Saada E., Lecesne A., Le Péchoux C., Blay J.Y., Piperno-Neumann S., Chevreau C., Bay J.O., Brouste V., Terrier P., Ranchère-Vince D., Neuville A., Italiano A.; French Sarcoma Group.
