Рак предстательной железы характеризуется относительно высокими показателями доли пациентов, находящихся на учете 5 и более лет, и индекса накопления. В результате на отдаленные исходы у этих пациентов начинают оказывать влияние другие факторы, отличные от основного заболевания.</p><p>Цель исследования — анализ онкологической заболеваемости пациентов с раком предстательной железы дополнительными злокачественными новообразованиями как одной из вероятных причин снижения их выживаемости в Республике Марий Эл.</p></sec><sec><title>Методы</title><p>Методы. Включено 1434 пациента с раком предстательной железы, впервые взятых на учет в период с 2012 по 2021 год. В этой выборке была идентифицирована группа пациентов, имевших дополнительные злокачественные новообразования (помимо рака предстательной железы), диагноз которых был установлен в период начиная за 6 месяцев до постановки диагноза рака предстательной железы и завершая концом 2021 года. Сравнение частоты злокачественных новообразований среди пациентов с раком предстательной железы и в общей популяции осуществляли в рамках анализа перекрестных таблиц 2 × 2 путем расчета относительного риска и его 95 % доверительного интервала. Достоверность различия констатировали, если рассчитанный 95 % доверительный интервал не включал 1. Кроме того, рассчитывали значения критерия хи-квадрат и соответствующие значения р. Статистические анализы выполняли в программных пакетах SPSS 13.0 (SPSS Inc., США) и Microsoft Excel 2007 (Microsoft Corporation, США).</p></sec><sec><title>Результаты</title><p>Результаты. В период начиная за 6 месяцев до постановки диагноза рака предстательной железы и до истечения 6 месяцев после этого было зарегистрировано 31 (32,29 %) дополнительное злокачественное новообразование (либо рак предстательной железы был констатирован в течение 6 месяцев после постановки диагноза другого злокачественного новообразования), через 6 месяцев — 1 год после постановки диагноза рака предстательной железы — 7 (7,29 %) дополнительных злокачественных новообразований и в более поздний период — 61 (63,54 %) дополнительное злокачественное новообразование. Наиболее распространенными первичными злокачественными новообразованиями среди всех пациентов являлись: рак мочевого пузыря (относительный риск (ОР) = 15,23 [95 % доверительный интервал (ДИ): 10,42–22,26]), немеланомный рак кожи (ОР = 3,77 [95 % ДИ 2,34–6,07]), колоректальный рак (ОР = 2,10 [95 % ДИ 1,24–3,54]), рак желудка (ОР = 2,01 [85 % ДИ 1,08–3,73]) и почки (ОР = 4,69 [95 % ДИ 2,51–8,75]).</p></sec><sec><title>Заключение</title><p>Заключение. Дополнительные злокачественные новообразования в течение 7,1 года (медиана) наблюдения развиваются у 6,7 % пациентов с раком предстательной железы, у которых данный риск выше среднепопуляционных значений, что делает данных пациентов группой риска.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Prostate cancer maintains a relatively high standardized uptake value and share of patients followed up for 5 or more years. Accordingly, distant outcomes in these patients appear to be influenced by factors other than the underlying disease.</p></sec><sec><title>Objective</title><p>Objective. To analyze the morbidity in prostate cancer patients with additional malignancies potentially linked with the decrease in the survival rate in the Mari El Republic.</p></sec><sec><title>Methods</title><p>Methods. The present study involved 1434 prostate cancer patients firstly enrolled in the period from 2012 to 2021. A group of patients in this sample was identified with additional malignancies (other than prostate cancer) diagnosed within the period from 6 months prior to prostate cancer diagnosis to the end of 2021. Comparison of the incidence of malignancies among prostate cancer patients and the general population was performed via a 2 × 2 crosstab analysis by calculating the relative risk and its 95% confidence interval. The difference was considered significant when 95% confidence interval did not include 1. In addition, chi-square values and corresponding p-values were calculated. Statistical analyses were performed using SPSS 13.0 (SPSS Inc., USA) and Microsoft Excel 2007 (Microsoft Corporation, USA).</p></sec><sec><title>Results</title><p>Results. 31 (32.29%) additional malignancies were identified (prostate cancer was diagnosed within 6 months before prostate cancer diagnosis and up to 6 months thereafter), 7 additional malignancies (7.29%) were registered 6 months to 1 year after prostate cancer diagnosis, and 61 additional malignancies (63.54%) during the later period. The most common primary malignancies among all patients included: bladder cancer (relative risk = 15.23 [95% confidence interval: 10.42–22.26]), nonmelanoma skin cancer (relative risk = 3.77 [2.34–6.07]), colorectal cancer (relative risk = 2.10 [1.24–3.54]), gastric cancer (relative risk = 2.01 [1.08–3.73]), and kidney cancer (relative risk = 4.69 [2.51–8.75]).</p></sec><sec><title>Conclusion</title><p>Conclusion. Within 7.1 years (median) of follow-up, additional malignancies develop in 6.70% of prostate cancer patients. These patients reveal the higher risk than the population average value, thereby constituting a risk group.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>дополнительные первичные злокачественные новообразования</kwd><kwd>относительный риск</kwd><kwd>заболеваемость</kwd><kwd>простатэктомия</kwd><kwd>дистанционная лучевая терапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>additional primary malignancies</kwd><kwd>relative risk</kwd><kwd>morbidity</kwd><kwd>prostatectomy</kwd><kwd>remote radiation therapy</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>авторы заявляют об отсутствии спонсорской поддержки при проведении исследования</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The authors declare that no funding was received for this study</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sung H, Ferlay J, Siegel RL, Laversanne M, Soerjomataram I, Jemal A, Bray F.
