С целью оценки прогностической значимости пПСА проведен ретроспективный анализ результатов лечения 714 пациентов c РПЖ, получавших комбинированную гормонолучевую терапию в ФГБУ «РНЦРХТ им. акад. А.М. Гранова» Минздрава РФ в период с января 1996 по декабрь 2016 г. В зависимости от распространенности опухолевого процесса пациенты были разделены на группы локализованного (n=272), местнораспространенного (n=231) и метастатического РПЖ (n=211). Для оценки прогностической значимости и установления пороговых значений признака пПСА, достоверно влиявших на показатели выживаемости, нами были последовательно применены методы ROC-анализа, множительных оценок Каплана–Мейера и модель пропорциональных рисков Кокса.</p></sec><sec><title>Результаты</title><p>Результаты. Значения признака пПСА у больных локализованным РПЖ, превышение которых сопровождалось снижением показателей ОВ и ОСВ, составили 0,34 нг/мл/см3 и 0,36 нг/мл/см3 соответственно. Больные с «низкой» пПСА демонстрировали достоверно лучшие показатели ОВ и ОСВ по результатам как однофакторного, так и многофакторного анализа. Пороговые значения признака пПСА у больных местнораспространенным РПЖ составили 0,28 нг/мл/см3 и 0,63 нг/мл/см3 для ОВ и ОСВ соответственно. Превышение указанных значений в группе больных местнораспространенным РПЖ, однако, не сопровождалось статистически достоверным снижением показателей выживаемости. У больных метастатическим РПЖ пороговые значения признака пПСА составили 2,25 нг/мл/см3 и 2,30 нг/мл/см3 для ОВ и ОСВ соответственно. По результатам однофакторного анализа больные генерализованным РПЖ с «низкой» пПСА демонстрировали статистически значимо лучшие результаты ОВ и ОСВ. По результатам многофакторного анализа, однако, выявленные тенденции не подтвердились.</p></sec><sec><title>Выводы</title><p>Выводы. Плотность ПСА является надежным инструментом оценки показателей выживаемости больных локализованным РПЖ, перенесших комбинированное гормонолучевое лечение.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose</title><p>Purpose. To evaluate prostate specifc antigen density (PSAD) as a predictor of overall (OS) and cancerspecifc survival (CSS) in patients with prostate cancer (PC) who have undergone combined hormonal-radiation therapy.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. In order to assess the prognostic signifcance of PSAD we retrospectively analyzed outcomes of 714 PCa patients who received combined hormonal-radiation therapy at the A.M. Granov Russian Scientifc Center of Radiology and Surgical Technologies, Ministry of Healthcare of Russia, between January 1996 and December 2016. Since the prognosis and management differ according to the extent of tumor involvement, patients were categorized into localized (n=272), locally advanced (n=231) and metastatic (n=211) PC groups. We equentially applied ROC-analysis, Kaplan-Meier product limit estimator and Cox proportional hazards model to assess the prognostic relevance and establish threshold values of PSAD that had a signifcant impact on survival rates.</p></sec><sec><title>Results</title><p>Results. In the localized PC group, PSAD threshold values of 0.34 ng/mL/cc and 0.36 ng/mL/cc were associated with a decrease in OS and CSS, respectively. Patients with “low” PSAD had signifcantly better OS and CSS survival rates in both uni- and multivariate analyses. In locally advanced PC group, PSAD threshold values were 0.28 ng/mL/cc and 0.63 ng/mL/cc for OS and CSS, respectively. However, exceeding the specifed values, in the locally advanced PC group, was not accompanied by a statistically signifcant decrease in survival rates. Finally, in the metastatic PC group, established PSAD threshold values were 2.25 ng/mL/cc and 2.30 ng/mL/ccfor OS and CSS, respectively. According to the results of univariate analysis, patients with “low” PSA tend to demonstrate statistically signifcant better OS and CSS rates. The results of multivariate analysis, however, failed to prove PSAD as an independent prognostic factor within the metastatic PC cohort. Conclusion. PSA density is a reliable tool for assessing survival rates in patients with localized PC who have undergone combined hormonal-radiation therapy.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>плотность простат-специфического антигена</kwd><kwd>комбинированная гормонолучевая терапия</kwd><kwd>исходы лечения.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>prostate-specific antigen density</kwd><kwd>combined hormonal-radiation therapy</kwd><kwd>survival rate</kwd><kwd>treatment outcomes</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">Albertsen P.C.
