Эпидемиологическими исследованиями отмечен прогрессивный рост заболеваемости почечно-клеточным раком (ПКР). Не смотря на улучшение лучевой диагностики ПКР, количество первично метастатических форм и количество вторично прогрессивных форм после радикального хирургического лечения остается довольно высоким, без явной тенденции снижения. Это может быть связано с изменением биологии самого ПКР, выражающейся в повышении агрессивности опухолевой ткани. Однако исследований по изменению биологических характеристик опухолей в течение длительного периода времени очень мало.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Оценить и сравнить профили больных ПКР, морфологические характеристики опухолей почек, варианты хирургического лечения и его результаты в двух последовательных декадах.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включено 306 оперированных и мониторированных больных ПКР. Пациенты разделены на две группы: 1 группа - 149 больных, пролеченных с 1996 по2005 г. и 2 группа - 157 больных, пролеченных с 2006 оп 2015 гг. В группах анализированы профили больных и морфологические характеристики опухолей.</p></sec><sec><title>Результаты</title><p>Результаты. У пациентов 2 группы опухоли &gt;4 см характеризовались более низкой степенью дифференцировки ткани (G2-G3) в сравнении с аналогичными по размерам опухолями 1 группы (54,54% против 48,57%) и стадией ТЗа (60% против 42,26%). Аналогичная разница отмечена для опухолей размерами 4-7 см (G2-G3 - 67.69% против 57,75%; ТЗа - 79,54% против 32,15%). Опухоли 2 группы в стадиях На, Tib, Т2 и ТЗа реже имели высокую степень дифференцировки (G1) в сравнении с опухолями аналогичных стадий 1 группы (52,17% против 59,26%, 35,71% против 58,06%, 11,11% против 18,75% и 12,12% против 28%, соответственно). Во 2 группе чаще, чем в 1 группе, отмечалось регионарное и отдаленное метастазирование (34,6% против 20,33%). Выживаемость во 2 группе снизилась в сравнении с 1 группой (3-летняя: общая - 78,37% против 83,02%, онкоспецифическая - 81,43% против 87,15%; 5-летняя: общая - 73,86% против 79,21%, онкоспецифическая - 78,69% против 83,91%).</p></sec><sec><title>Выводы</title><p>Выводы. Проведенный сравнительный анализ показал увеличение агрессивного потенциала опухолей во 2 группе в сравнении с 1 группой.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Epidemiological studies noted a progressive increase in the incidence of renal cell carcinoma (RCC). Despite the improvement in radiation diagnosis of RCC, the number of primary metastatic forms and number of secondary progressive forms after radical surgical treatment remains high with no apparent downward trend. This may be due to changes in the biology of RCC, which is expressed in the increasing aggressiveness of the tumor tissue. However, studies on the biological characteristics of the change in tumor for a long period of time is very small.</p></sec><sec><title>Objective</title><p>Objective. To evaluate and compare the profiles of patients with RCC, the morphological characteristics of renal tumors, the options for surgical treatment and its results in two consecutive decades.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study included 306 operated and monitored patients with RCC. The patients were divided into two groups: 1 group - 149 patients treated from 1996 to 2005 and 2 group - 157 patients treated from 2006 op 2015. The group analyzed the profiles of patients and morphological characteristics of the tumor.</p></sec><sec><title>Results</title><p>Results. In patients of the group 2, tumors &gt;4 cm were characterized by a lower degree of tissue differentiation (G2-G3) compared to the group 1 (54.54% vs. 48.57%) and T3a (60% vs. 42.26%). A similar difference was noted for tumors measuring 4-7 cm (G2-G3 - 67.69% vs. 57.75%, T3a - 79.54% vs. 32.15%). Tumors of the group2 in the stages Tla, Tib, T2 and T3a are less frequent had a high degree of differentiation (Gl) in comparison with tumors of similar stages of group 1 (52.17% vs. 59.26%, 35.71% vs. 58.06%, 11.11% vs. 18.75% and 12.12% vs. 28%, respectively.) In the group 2, regional and distant metastasis was noted more often than in group 1 (34.6% vs. 20.33%). Survival in group 2 decreased in comparison with group 1 (3-year-old: total - 78.37% vs. 83.02%, oncological - 81.43% vs. 87.15%, 5-year-old: total - 73.86% vs. 79.21%, oncological - 78.69% vs. 83.91% ).</p></sec><sec><title>Conclusions</title><p>Conclusions. The comparative analysis showed an increase in aggressive tumor potential in group 2 compared to group 1.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>почечно-клеточный рак</kwd><kwd>размеры опухолей</kwd><kwd>стадия</kwd><kwd>дифференцировка</kwd><kwd>морфологический вариант</kwd><kwd>выживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>renal cell carcinoma</kwd><kwd>tumor size</kwd><kwd>stage</kwd><kwd>differentiation</kwd><kwd>morphological variant</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">Jemal A, Siegel R, Ward E, Murray T, Xu J et al.
