In Russia, only a limited number of administrative regions possess the infrastructure to reliably perform such assessments. The first population-based cancer registry in Russia, established by our team in 1993 and operating in accordance with international standards, significantly expanded these capabilities to the level of a federal district. Utilizing data from the population-based cancer registry of the Northwestern Federal District (NWFD), we currently conduct research reflecting the real state of cancer care delivery in the country.</p> <p><bold>Aim.</bold> To analyze survival trends in patients with bladder cancer (BC) in the NWFD of Russia and to assess current therapeutic approaches.</p> <p><bold>Materials and methods.</bold> The study was based on a population-based cancer registry dataset comprising over 1.6 million cases, including 31,126 patients diagnosed with BC. Data were processed using standard methods in line with the Eurocare protocols.</p> <p><bold>Results.</bold> A marked increase in one-year observed survival was found: from 68.7 % to 75.5 %; as well as in five-year survival: from 42.8 % to 48.4 %. Overall mortality during the observation period declined from 31.3 % to 24.5 %. Among patients under 40 years of age, one-year survival exceeded 90 %, while in the elderly and long-lived cohorts it remained below 50 %. The proportion of patients diagnosed with localized BC increased from 46.9 % to 70.4 %, whereas the rate for advanced disease reached 39.0 %. Patients with stage IV urothelial carcinoma demonstrate the poorest survival outcomes, which is consistent with international epidemiological data. The advent of immunotherapy and targeted agents has marked a new era in the management of the disease, showing improvement in long-term outcomes in selected patient subgroups.</p> <p><bold>Conclusion.</bold> The data demonstrate a positive trend in one-year survival among BC patients in the NWFD of Russia, particularly in those diagnosed with localized disease. The improvement in stage distribution and a reduction in unspecified tumor localizations indicate enhanced diagnostic accuracy and higher quality of oncological care.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Расчет показателя выживаемости онкологических больных является ведущим критерием оценки деятельности онкологической службы. Такими возможностями обладает крайне ограниченное число административных территорий России. Созданный нами в 1993 г. первый в России популяционный раковый регистр, работающий по международным стандартам, расширил эти возможности до уровня федерального округа. На основе баз данных популяционного ракового регистра Северо-Западного федерального округа Российской Федерации (СЗФО РФ) мы в настоящее время осуществляем исследования по реальному состоянию в стране деятельности онкологической службы.</p> <p><bold>Цель исследования</bold> – изучить закономерности изменения параметров выживаемости больных раком мочевого пузыря (РМП) в СЗФО РФ, рассмотреть современные возможности лечения больных.</p> <p><bold>Материалы и методы.</bold> Материалом для исследования являлась база данных популяционного ракового регистра СЗФО РФ объемом более 1,6 млн наблюдений, включая 31 126 пациентов с РМП. Использованы стандартные методы обработки данных по программе Eurocare.</p> <p><bold>Результаты.</bold> Установлено существенное увеличение 1-летней наблюдаемой выживаемости с 68,7 до 75,5 %, 5-летней – с 42,8 до 48,4 %. Летальность больных за весь период наблюдения снизилась с 31,3 до 24,5 %. Одногодичная летальность больных РМП среди лиц до 40 лет превысила 90 %, среди пациентов старческих групп и долгожителей она достигла 50 %. Число больных РМП с локализованным опухолевым процессом за период наблюдения возросло с 46,9 до 70,4 %, с распространенным процессом составило 39,0 %. У пациентов с IV стадией уротелиального рака показатели выживаемости остаются наиболее неблагоприятными, что согласуется с международными эпидемиологическими данными. Согласно представленному обзору литературы, появление иммунотерапии и таргетных препаратов обозначило качественно новый этап в лечении заболевания, продемонстрировав улучшение долгосрочных исходов у части пациентов.</p> <p><bold>Заключение.</bold> Данные свидетельствуют о положительной динамике 1-летней выживаемости больных РМП в СЗФО РФ, особенно в группах с локализованным процессом и при ранней диагностике. Улучшение структуры стадий и снижение доли неуточненных локализаций указывают на повышение качества онкологической помощи и верификации диагноза.</p></trans-abstract><kwd-group xml:lang="en"><kwd>malignant tumor</kwd><kwd>bladder cancer</kwd><kwd>database</kwd><kwd>population-based cancer registry</kwd><kwd>Northwestern Federal District of Russia</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>злокачественное новообразование</kwd><kwd>рак мочевого пузыря</kwd><kwd>база данных</kwd><kwd>популяционный раковый регистр</kwd><kwd>Северо-Западный федеральный округ Российской Федерации</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">Merabishvili V.M.
