The analysis included 326 patients who underwent partial nephrectomy (PN) in 210 (64.42 %) and radical nephrectomy (RN) - in 116 (35.58 %). Stage cT1a tumors were found in 129 (39.57 %), cT1b - in 149 (45.71 %), cT2a - in 48 (14.72 %) cases. PN and RN for cT1a was performed in 113 (53.81 %) and 16 (13.79 %), for cT1b -in 86 (40.95 %) and 63 (54.31 %), for cT2a - in 11 (5.24 %) and 37 (31.90 %) patients. We used open approach in 5 (1.53 %), laparoscopic in 148 (45.26 %) and robotic in 173 (53.21 %). The median follow-up was 49.9 [26.0; 81.4] months.</p><p><bold>Results</bold>. In the group of patients with stage cT1a disease, 4 recurrences of the tumor process were revealed (3 local recurrences after PN and 1 after RN). Seven deaths were recorded (4 after PR and 3 after RN). Two deaths occurred due to the progression of kidney cancer (1 after PN and 1 after RN). 5-year disease-free survival after PN and RN was 95.93 ± 2.32 % versus 92.31 ± 7.39 % (<italic>p</italic> &gt;0.05); 5-year overall survival - 96.48 ± 2.08 % versus 85.56 ± 9.65 % (<italic>p</italic> &gt;0.05); 5-year cancer-specific survival - 98.33 ± 1.65 % versus 92.25 ± 6.5 % (<italic>p</italic> &gt;0.05).</p><p>In the group of patients with stage cT1b disease, 12 recurrences were revealed (5 after PN and 7 after RN). 14 deaths were recorded (4 after PN and 10 after RN). Four deaths were related to the development of kidney cancer (all after RN). 5-year disease-free survival after PN and RN was 92.97 ± 3.1 % versus 86.99 ± 4.64 % (<italic>p </italic>&gt;0.05); 5-year overall survival -95.1 ± 2.78 % versus 88.63 ± 4.4 % (<italic>p </italic>&gt;0.05); 5-year cancer-specific survival - 100 % versus 94.1 ± 3.33 % (<italic>p</italic> &gt;0,05).</p><p>There were no recurrences of the oncological process or deaths after PN in the group of patients with the stage of cT2a disease during four years of follow-up. After RN six recurrences of the oncological process, four deaths (3 of them due to the progression of kidney cancer) were recorded. Thus, the disease-free survival at was 80.57 ± 7.15 %; overall survival - 90.28 ± 5.34 %; cancer-specific survival - 93.63 ± 4.37 %.</p><p><bold>Conclusion</bold>. PN is the priority treatment for renal cell cancer. Oncological results of nephron-sparing surgery are superior to the results of RN, however, these differences are not reliable and require a longer study.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> - оценка отдаленных онкологических результатов хирургического лечения пациентов с раком почки стадии сТ1-сТ2аN0M0.</p><p><bold>Материалы и методы</bold>. В исследование включены 326 пациентов, среди которых 210 (64,42 %) выполнена резекция почки (РП), 116 (35,58 %) - радикальная нефрэктомия (РНЭ). Стадия опухоли сТ1а диагностирована в 129 (39,57 %), сТ1b - в 149 (45,71 %), сТ2а - в 48 (14,71 %) случаях. РП при стадии сТ1а выполнили 113 (53,81 %), при сТ1b -86 (40,95 %), при сТ2а - 11 (5,24 %) пациентам; РНЭ - 16 (13,79 %), 63 (54,31 %) и 37 (31,90 %) пациентам соответственно. Операции выполняли открытым (1,53 %), лапароскопическим (45,26 %) и робот-ассистированным (53,21 %) доступами. Медиана продолжительности наблюдения составила 49,9 [26,0; 81,4] мес.</p><p><bold>Результаты</bold>. За период наблюдения в группе пациентов со стадией заболевания сТ1а выявлено 4 рецидива опухолевого процесса (3 местных рецидива после РП и 1 рецидив после РНЭ). Зафиксировано 7 летальных исходов (4 после РП и 3 после РНЭ). Причиной 2 летальных исходов стало прогрессирование рака почки (1 после РП и 1 после РНЭ). После РП и РНЭ 5-летняя безрецидивная выживаемость составила 95,93 ± 2,32 и 92,31 ± 7,39 % (<italic>p</italic> &gt;0,05), 5-летняя общая выживаемость - 96,48 ± 2,08 и 85,56 ± 9,65 % (<italic>p</italic> &gt;0,05), 5-летняя раковоспецифическая выживаемость - 98,33 ± 1,65 и 92,25 ± 6,5 % (<italic>p</italic> &gt;0,05) соответственно.</p><p>В группе пациентов со стадией заболевания сТ1b выявлено 12 рецидивов (5 после РП и 7 после РНЭ). Зафиксировано 14 летальных исходов (4 после РП и 10 после РНЭ). Причиной 4 летальных исходов стало прогрессирование рака почки (все после РНЭ). После РП и РНЭ 5-летняя безрецидивная выживаемость составила 92,97 ± 3,1 и 86,99 ± 4,64 % (<italic>p</italic> &gt;0,05), 5-летняя общая выживаемость - 95,1 ± 2,78 и 88,63 ± 4,4 % (<italic>p</italic> &gt;0,05), 5-летняя раковоспецифическая выживаемость - 100 и 94,1 ± 3,33 % (<italic>p</italic> &gt;0,05) соответственно.</p><p>В группе пациентов со стадией заболевания сТ2а после РП рецидивов онкологического процесса и летальных исходов не зафиксировано. После РНЭ отмечено 6 рецидивов онкологического процесса и 4 летальных исхода (3 из них по причине прогрессирования рака почки). Таким образом, за период наблюдения безрецидивная выживаемость после РП составила 100 % против 80,57 ± 7,15 % после РНЭ, общая выживаемость - 100 % против 90,28 ± 5,34 %, раковоспецифическая выживаемость - 100 % против 93,63 ± 4,37 %.</p><p><bold>Заключение</bold>. РП является эффективным методом лечения опухолей почек стадии сТ1-Т2а, онкологические результаты которого превосходят таковые при РНЭ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>kidney cancer</kwd><kwd>partial nephrectomy</kwd><kwd>radical nephrectomy</kwd><kwd>long-term oncological results</kwd><kwd>survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак почки</kwd><kwd>резекция почки</kwd><kwd>радикальная нефрэктомия</kwd><kwd>отдаленные онкологические результаты</kwd><kwd>выживаемость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Axel E.M., Matveev V.B.
