Median age was 58 years (range: 16-82 years); the male to female ratio was 2.3:1. The symptoms of tumor venous thrombosis were identified in 232 patients (30.2 %); laboratory abnormalities at baseline were observed in 456 patients (59.3 %). Grade I and II tumor thrombosis was diagnosed in 456 (59.3 %) and 201 (26.2 %) patients, respectively; grade III and IV thrombosis was found in 171 (22.3 %) and 177 (23.0 %) patients, respectively. One hundred and twenty-nine participants (16.8 %) had infrarenal inferior vena cava thrombosis. Regional metastases were detected in 188 individuals (24.4 %), distant metastases were registered in 274 patients (35.7 %). All patients have undergone surgery: either radical (n = 555; 72.3 %) or cytoreductive (n = 213; 27.7 %). All primary tumors were histologically classified as RCC (G<sub>3-4</sub> in 337 cases; 43.9 %). A total of 719 patients (93.6 %) survived the perioperative period; 183 patients with metastasis (23.8 %) received systemic antitumor therapy.</p><p><bold>Results.</bold> The median follow-up was 24 months (range: 1-200 months). The 24-month overall and cancer-specific survival of all patients were 96.9 and 99.7 %, respectively; recurrence-free survival of patients after radical surgery reached 92.9 %. Progression-free survival among those patients who underwent cytoreductive surgery and received first-line therapy/follow-up was 41.7 %. Negative predictive factors of overall survival included hepatomegaly (p = 0.024), ascites (p = 0.033), level IV tumor thrombosis (p &lt;0.0001), infrarenal inferior vena cava thrombosis (p = 0.002), regional metastases (p &lt;0.0001), and cytoreductive surgery (p = 0.012). Depending on the number of risk factors, we have identified 3 prognostic groups: favorable (0 factors), intermediate (1-2 factors), and poor (3-6 factors). Median overall survival differed significantly between the groups and was 128.6 ± 11.8; 40.9 ± 6.7 and 12.3 ± 2.2 months, respectively (p &lt;0.0001 for all).</p><p><bold>Conclusion.</bold> Stratification of patients operated on for RCC and venous tumor thrombosis with their allocation to prognostic groups will ensure the choice of an optimal management strategy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> - выделение независимых факторов неблагоприятного прогноза выживаемости больных почечно-клеточным раком (ПКР) с опухолевым венозным тромбозом, подвергнутых нефрэктомии, тромбэктомии.</p><p><bold>Материалы и методы</bold>. В исследование включены данные 768 больных ПКР с опухолевым венозным тромбозом, подвергнутых нефрэктомии, тромбэктомии. Медиана возраста - 58 (16-82) лет, соотношение мужчин и женщин -2,3:1. Симптомы опухолевого венозного тромбоза имелись у 232 (30,2 %), исходные лабораторные отклонения -у 456 (59,3 %) пациентов. Опухолевый тромбоз I уровня диагностирован у 219 (28,5 %), II уровня - у 201 (26,2 %), III уровня - у 171 (22,3 %) и IV уровня - у 177 (23,0 %) пациентов. В 129 (16,8 %) случаях тромбоз распространялся в инфраренальный отдел нижней полой вены. Регионарные метастазы диагностированы в 188 (24,4 %), отдаленные -в 274 (35,7 %) наблюдениях. Всем больным выполнено хирургическое вмешательство: радикальное - 555 (72,3 %), циторедуктивное - 213 (27,7 %). Гистологически все первичные опухоли имели строение ПКР (G<sub>3-4</sub> 337; 43,9 %). Периоперационный период пережили 719 (93,6 %) больных, системную противоопухолевую терапию получали 183 (23,8 %) пациента с метастазами.</p><p><bold>Результаты.</bold> Медиана наблюдения за всеми выжившими пациентами - 24 (1-200) мес. В исследовании 24-месячная общая выживаемость и специфическая выживаемость всех пациентов составили 96,9 и 99,7 % соответственно; безрецидивная выживаемость радикально оперированных больных достигла 92,9 %, беспрогрессивная выживаемость пациентов, перенесших циторедуктивную операцию и получавших 1-ю линию терапии/динамическое наблюдение, -41,7 %. Независимыми факторами неблагоприятного прогноза общей выживаемости явились гепатомегалия (р = 0,024), асцит (р = 0,033), опухолевый тромбоз IV уровня (р &lt;0,0001), тромбоз инфраренального сегмента нижней полой вены (р = 0,002), регионарные метастазы (р &lt;0,0001) и нерадикальное хирургическое лечение (р = 0,012). В зависимости от количества факторов прогноза выделено 3 группы: благоприятного (0 факторов), промежуточного (1-2 фактора) и неблагоприятного (3-6 факторов) прогноза. Медиана общей выживаемости между группами значимо различалась и составила 128,6 ± 11,8; 40,9 ± 6,7 и 12,3 ± 2,2 мес соответственно (р &lt;0,0001 для всех).</p><p><bold>Заключение.</bold> Стратификация оперированных больных ПКР с опухолевым венозным тромбозом с использованием выделенных прогностических групп может помочь в выборе дальнейшей тактики ведения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>renal cell carcinoma</kwd><kwd>tumor venous thrombosis</kwd><kwd>nephrectomy</kwd><kwd>thrombectomy</kwd><kwd>risk factor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак почки</kwd><kwd>опухолевый венозный тромбоз</kwd><kwd>нефрэктомия</kwd><kwd>тромбэктомия</kwd><kwd>фактор неблагоприятного прогноза выживаемости  </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">Davydov M.I., Matveev V.B., Volkova M.I. et al.
