We emphasize that the assessment of treatment and prognosis using specific markers is a promising method. However, clinical data currently outpace the results of molecular testing. Patients with luminal BCa demonstrate worse response to pharmacotherapy than those with other BCa types. The implementation of new drugs such as avelumab, enfortumab, and new drug combinations into clinical practice raised hopes to improve treatment outcomes of patients with locally advanced and metastatic bladder cancer. The development of new pharmacotherapy and immunotherapy regimens will improve treatment outcomes. We describe the experience of some foreign countries with the treatment and outpatient follow-up of patients after radical cystectomy. The article also contains the guidelines by the European Association of Urology on the treatment of patients with urinary tract cancers during the COVID-19 pandemic.</p></abstract><trans-abstract xml:lang="ru"><p>В обзоре представлены современные данные по диагностике и лечению больных раком мочевого пузыря. Подчеркивается, что использование маркеров в оценке лечения и прогнозирования является перспективным методом. Однако в настоящее время клинические данные опережают результаты молекулярно-генетических исследований. Показано, что у больных с люминальным подтипом рака мочевого пузыря ответ на лекарственную терапию хуже по сравнению с таковым у пациентов с другими видами. Надежды на улучшение результатов лечения местно-распространенного и метастатического рака мочевого пузыря связаны с изучением и внедрением в практику новых препаратов, таких как авелумаб, энфортумаб ведотин, и новых комбинаций. Разработка новых схем лекарственной терапии и иммунотерапии позволит улучшить результаты лечения. Представлен опыт ряда зарубежных стран по лечению и амбулаторному наблюдению за пациентами после радикальной цистэктомии. Даны рекомендации Европейского общества урологов по лечению пациентов с онкоурологическими заболеваниями в период пандемии COVID-19.</p></trans-abstract><kwd-group xml:lang="en"><kwd>bladder cancer</kwd><kwd>genetic marker</kwd><kwd>radical cystectomy</kwd><kwd>follow-up</kwd><kwd>recommendation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак мочевого пузыря</kwd><kwd>генетический маркер</kwd><kwd>радикальная цистэктомия</kwd><kwd>динамическое наблюдение</kwd><kwd>рекомендация</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>EAU Guidelines.
