All patients were undergone a repeated transurethral resection was performed in 6 weeks after the first operation. In the case of the absence of residual tumor, cystoscopy was performed every 3 months during the first year then every 3–6 months during next 5 years. The average time of follow-up was 43.2 months. According to the standard protocol an immunohistochemical study with detection of p53 was carried out on 72 sections of formalin-fixed and paraffin-embedded tumor fragments. p53 expression was also determined in 10 histologically unchanged fragments of the bladder mucosa.<bold/></p><p><bold>Results.</bold> Depending on the percent of nuclei with p53 expression, two groups were identified. The first group included 40 tumor samples (55.5 %) with p53 expression less than 20 % and 17 tumor samples (23.6 %) without p53 expression. The second group included 15 tumor samples (20.9 %) with p53 expression more than 20 % (4 patients – 20–40 %, 8 patients – 40–60 %, 3 patients – 60–80 %). р53 expression was not determined in the all 10 samples of normal bladder tissue. During follow-up period 1 of 57 patients of the first group has a disease progression comparing with 13 of 15 patients in the second group. Patients of the both group were similar in respect with clinical characteristics. The mean time to disease progression was 17.3 months.<bold/></p><p><bold>Conclusion.</bold> Results of the current study shows that p53 immunohistochemical marker is a prognostic factor in the development of superficial urothelial bladder carcinoma.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Примерно 80 % первично диагностируемых уротелиальных карцином мочевого пузыря являются поверхностными. При этом у 10–20 % пациентов с первично выявляемым поверхностным уротелиальным раком впоследствии развивается мышечно-инвазивное и метастатическое поражение. В связи с этим важной является идентификация прогностических факторов, которые могли бы выделить группу поверхностных опухолей с более высоким потенциалом агрессивности.<bold/></p><p><bold>Цель исследования</bold> – определение роли экспрессии р53 как фактора прогноза в развитии поверхностных уротелиальных карцином мочевого пузыря.<bold/></p><p><bold>Материалы и методы</bold>. Ретроспективно проанализированы 72 истории болезни пациентов (11 женщин и 61 мужчины) с первично диагностированным поверхностным уротелиальным раком мочевого пузыря I и II степеней злокачественности. Всем пациентам была проведена повторная трансуретральная резекция через 6 нед после 1-й операции. При отсутствии остаточной опухоли пациентам выполняли цистоскопическое исследование каждые 3 мес в течение 1-го года после вмешательства и каждые 3–6 мес в последующем. Среднее время наблюдения составило 43,2 мес. Иммуногистохимическое исследование с онкопротеином р53 было проведено по стандартному протоколу на 72 срезах поверхностных зафиксированных формалином и залитых в парафин фрагментов опухоли. Экспрессия р53 также была определена в 10 гистологически неизмененных фрагментах слизистой оболочки мочевого пузыря.<bold/></p><p><bold>Результаты.</bold> В зависимости от процента ядер с экспрессией р53 были выделены 2 группы: 1-ю составили 40 (55,5 %) образцов опухоли с экспрессией р53 &lt; 20 % и 17 (23,6 %) образцов без экспрессии р53; 2-ю – 15 (20,9 %) образцов с экспрессией р53 &gt; 20 % (4 пациента – 20–40 %, 8 – 40–60 %, 3 – 60–80 %). В нормальной ткани мочевого пузыря во всех 10 образцах экспрессия р53 не определялась. За время наблюдения у 1 из 57 пациентов 1-й группы было отмечено прогрессирование заболевания, во 2-й группе их число достигало 13 из 15. Пациенты групп сравнения одинаковы по клиническим характеристикам. Среднее время до прогрессирования заболевания составило 17,3 мес.<bold/></p><p><bold>Заключение.</bold> Результаты настоящего исследования доказывают, что онкомаркер p53 является фактором прогноза в развитии поверхностных уротелиальных карцином мочевого пузыря.</p></trans-abstract><kwd-group xml:lang="en"><kwd>superficial bladder cancer</kwd><kwd>prognosis</kwd><kwd>recurrence</kwd><kwd>markers</kwd><kwd>p53 gene</kwd><kwd>expression</kwd><kwd>immunohistochemical study</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>поверхностный рак мочевого пузыря</kwd><kwd>прогноз</kwd><kwd>рецидив</kwd><kwd>маркеры</kwd><kwd>ген р53</kwd><kwd>экспрессия</kwd><kwd>иммуногистохимическое исследование</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">1.
