В исследование включены 945 пациентов и 120 клинически здоровых лиц. Диагноз рака мочевого пузыря верифицирован морфологически. Результаты исследования проанализированы с использованием непараметрических методов статистики. Выявлены информативные показатели для дооперационной оценки степени инвазии опухоли мочевого пузыря (CYFRA 21-1, UBC, NMP-22, BTA), количества опухолевых очагов (TPA, TPS, UBC), степени злокачественности (NMP-22). Определена диагностическая чувствительность и диагностическая специфичность каждого показателя.</p></abstract><trans-abstract xml:lang="en"><p>The article provides novel information about the concentrations of CYFRA 21-1, TPA, TPS, UBC, NMP-22, BTA and CEA tumor markers in body fluids of stage I-IV bladder cancer patients. The study comprised 945 bladder cancer patients and 120 clinically healthy individuals. Bladder cancer was morphologically verified in all patients. Data were analyzed using nonparametric statistical methods. Выявлены информативные показатели для дооперационной оценки степени инвазии опухоли мочевого пузыря (CYFRA 21-1, UBC, NMP-22, BTA), количества опухолевых очагов (TPA, TPS, UBC), степени злокачественности (NMP-22). Markers with reasonable performance for preoperative assessment of bladder cancer invasion (CYFRA 21-1, UBC, NMP-22, BTA), number of tumor foci (TPA, TPS, UBC) and tumor grade (NMP-22) were identified. Sensitivity and specificity of all markers were defined.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак мочевого пузыря</kwd><kwd>опухолевые маркеры</kwd><kwd>диагностическая информативность</kwd><kwd>bladder cancer</kwd><kwd>tumor markers</kwd><kwd>diagnostic performance</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">Молекулярные маркеры в диагностике мышечно-неинвазивного рака мочевого пузыря / П.В.
