Combined hormonal-radiation therapy has become a standard of care for localized prostate cancer definitive treatment. As many as 30 % of men are at risk for disease progression within 10 years following radical treatment.</p><p><bold>Aim.</bold> To assess the significance of prostate-specific antigen (PSA) density as a predictor of recurrence-free survival following combined hormonal-radiation therapy in patients with localized prostate cancer.</p><p>Materials and methods. We conducted a retrospective study of 272 patients with clinically localized prostate cancer treatment results who received combined hormonal-radiation therapy between January 1996 and December 2016.</p><p><bold>Results.</bold> On the basis of our study, we confirmed high prognostic value of PSA density among patients with localized prostate cancer who received combined hormonal-radiation treatment. We utilized ROC-analysis in order to determine the threshold value of the PSA density index – 0.376 ng/ml/cm<sup>3</sup>, exceeding of which was associated with statistically significant reduction in the recurrence-free survival rate. The area under the curve was 0.711 (95 % confidence interval 0.653–0.764; p &lt;0.0001). The risk of recurrence increased with rising of PSA density.</p><p><bold>Conclusion.</bold> PSA density has proven to be a reliable tool for assessing the risk of prostate cancer recurrence among patients with localized prostate cancer who have undergone combined hormonal-radiation therapy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Рак предстательной железы является одним из наиболее распространенных онкологических заболеваний. Комбинированная гормонолучевая терапия относится к основным методам радикального лечения рака предстательной железы. У 30 % мужчин возникает прогрессирование заболевания в течение 10 лет после радикального лечения.</p><p><bold>Цель исследования</bold> – определение значимости плотности простатического специфического антигена (ПСА) в качестве предиктора безрецидивной выживаемости после перенесенного комбинированного гормонолучевого лечения у больных локализованным раком предстательной железы.</p><p><bold>Материалы и методы</bold>. В целях оценки клинической и прогностической значимости параметра плотности ПСА проведено ретроспективное исследование результатов лечения 272 пациентов, перенесших комбинированную гормонолучевую терапию в период с января 1996 г. по декабрь 2016 г.</p><p><bold>Результаты</bold>. Установлено прогностическое значение плотности ПСА у больных локализованным раком предстательной железы, получивших комбинированное гормонолучевое лечение. С помощью ROC-анализа определено пороговое значение показателя плотности ПСА – 0,376 нг/мл/см<sup>3</sup>, превышение которого связано со статистически значимым снижением уровня безрецидивной выживаемости. Площадь под ROC-кривой (AUC) составила 0,711 (95 % доверительный интервал 0,653–0,764; p &lt;0,0001). Риск возникновения рецидива возрастал по мере увеличения показателя плотности ПСА.</p><p><bold>Заключение.</bold> Плотность ПСА, обладая высокими показателями клинической и прогностической значимости, представляет собой надежный инструмент оценки риска возникновения рецидива рака предстательной железы у пациентов, перенесших комбинированное гормонолучевое лечение.</p></trans-abstract><kwd-group xml:lang="en"><kwd>prostate cancer</kwd><kwd>combined hormonal-radiation therapy</kwd><kwd>recurrence-free survival</kwd><kwd>prostate-specific antigen density</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак предстательной железы</kwd><kwd>комбинированная гормонолучевая терапия</kwd><kwd>безрецидивная выживаемость</kwd><kwd>плотность простатического специфического антигена</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed without external funding.</funding-statement><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Rider J.R., Wilson K.M., Sinnott J.A. et al.
