ПАЦИЕНТЫ И МЕТОДЫ. Ретроспективно изучены материалы клинического обследования 16 больных переходно-клеточным раком мочевого пузыря. Сосуды образцов опухолевой ткани были окрашены иммуногистохимическим методом с использованием антител к CD34. РЕЗУЛЬТАТЫ. Глубина инвазии рака Tis, Та, Т1,Т2, Т3 Т4 и ТХ была выявлена в 1 (6%), 2(13%), 1 (6%), 6 (36%), 2 (13%), 2 (13%), 2 (13%) случаях соответственно, а степень дифференцировки G1, G2 и G3 – в 6 (36%), 6 (36%) и 4 (28%) случаях соответственно. С понижением степени дифференцировки переходно-клеточных карцином число микрососудов в опухолевой ткани возрастало (r=0,68; p=0,04; rs=0,56; p=0,023; H=6,55; p=0,038; F=9,41; p=0,003). Опухоли с умеренной и низкой степенью дифференцировки достоверно различались по плотности микрососудов (t=2,94; p=0,019). Сравнительное изучение опухолевой ткани со степенями дифференцировки G1 и G3 показало, что они отличались по числу микрососудов в поле зрения в наибольшей степени (t=4,34; p=0,002; U=0,00; p=0,011). ЗАКЛЮЧЕНИЕ. Проведенное исследование дает основание считать, что определение ангиогенной активности карцином мочевого пузыря может быть полезным для прогноза течения заболевания. Определение интенсивности кровоснабжения опухоли позволило нам сделать вывод о том, что оно тесно связано со степенью дифференцировки переходно-клеточных карцином и может быть рекомендовано в качестве клинико-морфологического критерия, дополняющего существующую классификацию переходно-клеточного рака мочевого пузыря.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM of the study to investigate the special features of angiogenesis of transitional cell cancer of urinary bladder and correlate them with clinical data, degree of differentiation and deep invasion of the tumor. PATIENTS AND METHODS. The retrospective analysis of clinically investigated 16 patients with transitional-cellular tumor of urinary bladder was conducted. The vessels of the tumor tissues were colored by means of immunohistochemical method with the use of CD34 antibodies. RESULTS. The depth of the invasion of the tumor Tis, Ta, T1, T2, T3, T4 and TX was detected in 1 (6 %), 2 (13 %), 1 (6 %), 2 (13 %), (13%), 2 (13 %) cases accordingly, and the stage of the differentiation G1, G2 and G3 – in 6 (36 %), 6 (36 %) and 4 (28 %) cases accordingly. With the lower stage of the differentiation of transitional cell carcinoma the amount of micro-vessels in the tumor tissues increased (r=0,68; p=0,04; rs=0,56; p=0,023; H=6,55; p=0,038; F=9,41; p=0,003). Tumors with moderate and low stage of the differentiation were reliably different by the density of micro-vessels (t=2,94; p=0,019). The comparative study of tumor tissue with the stages of differentiation G1 and G2 showed that they differ in the number of micro-vessels in the observation field inthe greatest extent (t=4,34; p=0,02; U=0,00; p=0,011). CONCLUSION. The conducted investigation allows to make the conclusion that the determination of the angiogenic activity of carcinoma of the urinary bladder can be a valuable factor for prognosis of the disease course. The determination of the intensity of the blood flow of the tumor allows us to suppose that it is closely connected with the differentiation stage of the transitional cell carcinoma and could be recommended as a clinic-morphological criteria, supplementing the current classification of the transitional-cellular tumor of urinary bladder.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>переходно-клеточный рак мочевого пузыря</kwd><kwd>ангиогенез</kwd><kwd>прогноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>transitional-cellular tumor of urinary bladder</kwd><kwd>angiogenesis</kwd><kwd>prognosis</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">Parkin DM, Pisani P, Ferlay J.
