Цель исследования: сравнительная оценка содержания VEGF, VEGFR1 и VEGFR2 в сыворотке крови практически здоровых людей, больных раком и доброкачественными опухолями почки, анализ их взаимосвязи с основными клинико-морфологическими особенностями новообразований. Обследованы 99 больных раком и 10 больных доброкачественными опухолями почки. В контрольную группу вошли 80 человек. Концентрацию исследуемых белков определяли с помощью наборов реактивов для прямого иммуноферментного анализа Quantikine® (R&amp;D Systems, США). Содержание VEGF, VEGFR1 and VEGFR2 в сыворотке крови больных раком почки достоверно выше, чем в контроле. Уровень VEGF также повышен у больных доброкачественными опухолями. При пороговом уровне VEGF, равном 365 пг/мл, диагностическая чувствительность выявления первичного рака почки составляет 67 %, специфичность - 70 %. Только уровень VEGFR1 положительно коррелирует со стадией заболевании и индексами T и N. Взаимосвязи уровня маркеров с гистологическим строением и степенью дифференцировки рака почки не выявлено. Таким образом, VEGF и его рецепторы имеют ограниченное диагностическое значение при раке почки, но могут быть использованы для мониторинга и предсказания эффективности антиангиогенной терапии.</p></abstract><trans-abstract xml:lang="en"><p>Achievements in the treatment of renal cancer are associated with antiangiogenic therapy. Therefore, exploration of molecular markers characterizing its angiogenic activity are on the agenda. Objective of the study: comparative evaluation of VEGF, VEGFR 1 and VEGFR2 content in blood serum of healthy persons, renal cancer and benign tumor patients, analysis of associations with the main clinical and pathologic features. 99 cancer and 10 benign renal tumor patients comprised the study group. Control group involved 80 persons. Concentration of the proteins studied was measured with direct ELISA kits (Quantikine®, R&amp;D Systems, USA). VEGF, VEGFR 1 and VEGFR2 levels in the sera of renal cancer patients were significantly higher than in control group. Serum VEGF was also higher in renal cancer patients than in those with benign tumors. At 365 pg/m cut-off level VEGF diagnostic sensitivity for primary renal cancer comprised 67 %o, with specificity 70 %. Only serum VEGFR 1 level was positively associated with clinical stage, T and N indices. No associations with tumor histological type or differentiation grade were found. Conclusion: VEGF and its receptors' levels in blood serum have limited diagnostic value in renal cancer, but might be regarded as promising markers for monitoring of antiangiogenic therapy results and prediction of its efficiency.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак почки</kwd><kwd>сыворотка крови</kwd><kwd>диагностические характеристики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>VEGF</kwd><kwd>VEGFR1</kwd><kwd>VEGFR2</kwd><kwd>renal cancer</kwd><kwd>vascular endothelial growth factor (VEGF)</kwd><kwd>VEGFR 1</kwd><kwd>VEGFR 2</kwd><kwd>blood serum</kwd><kwd>diagnostic characteristics</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">Ainsworth N.
