Материал и методы исследования: обследовано 75 пациентов с подозрением на рак предстательной железы по данным пальцевого ректального исследования и (или) повышением уровня общего простатспецифического антигена сыворотки крови. При этом обязательным условием было наличие гипоэхогенных очагов в периферической зоне предстательной железы. Всем пациентам проводилась системная и прицельная биопсия. Прицельная биопсия осуществлялась из гипоэхогенных очагов - зон интереса, которые были предварительно выбраны для количественного анализа контрастного усиления. В соответствии с морфологическими данными были выделены две группы очагов: 30 очагов в группе “РПЖ” (основная группа) и 45 очагов в группе “не РПЖ” (группа сравнения). ТРУЗИ выполнялись на аппарате Epiq 5 (Philips, Нидерланды) внутриполостным микроконвексным датчиком 4-10 МГц. Использовался ультразвуковой контрастный препарат Соновью (Bracco Swiss S.A., Швейцария). При анализе кривой “время-интенсивность” оценивались следующие безразмерностные индексы, представляющие собой отношение соответствующих абсолютных параметров в зоне интереса и эталонной зоне: индекс WIR (wash-in rate), индекс TTP (time to peak), индекс PI (peak intensity), индекс MTT (mean transit time), индекс TPH (time from peak to one half) и индекс RT (rise time). Результаты исследования: достоверные различия между группами получены по индексам WIR (P &lt; 0,0001), PI (P &lt; 0,0001), TTP (P = 0,0008) и RT (P = 0,0248). Тест “индекс PI &gt; 1,174 - рак предстательной железы” характеризуется чувствительностью 83,3%, специфичностью 88,9%, предсказательной ценностью положительного теста 83,3%, предсказательной ценностью отрицательного теста 88,9%, AUC 0,910. Тест “индекс WIR &gt; 1,432 - рак предстательной железы” характеризуется чувствительностью 76,7%, специфичностью 82,2%, предсказательной ценностью положительного теста 74,2%, предсказательной ценностью отрицательного теста 84,1%, AUC 0,808. Тест “индекс TTP ≤ 0,936 - рак предстательной железы” характеризуется чувствительностью 73,3%, специфичностью 66,7%, предсказательной ценностью положительного теста 59,5%, предсказательной ценностью отрицательного теста 78,9%, AUC 0,729. Определяется достоверная корреляция умеренной силы между суммой Глисона и индексом PI (rS = 0,394, P = 0,0311). Выводы: использование относительных параметров (индексов) количественного анализа трансректального ультразвукового исследования с контрастным усилением может привести к повышению эффективности прицельных биопсий. Индексы отличаются большей информативностью, чем абсолютные параметры.</p></abstract><trans-abstract xml:lang="en"><p>To reveal the most significant relative parameters (indices) of quantitative transrectal contrast-enhanced ultrasound in the diagnosis of prostate cancer using the results of ultrasound guided targeted prostate biopsy. Material and methods: 75 patients with the suspicion for prostate cancer based on results of digital rectal examination and/or increased level of serum total prostate-specific antigen. One of obligatory inclusion criteria to the study was the presence of hypoechoic foci in the peripheral zone of prostate. A targeted ultrasound guided biopsy of hypoechoic foci pre-selected for the quantitative analysis of contrast enhanced ultrasound performed in all patients, as well as systemic prostate biopsy. According to the morphological data, all foci were divided into two groups: main (prostate cancer) group consisted of 30 lesions and control (non-prostate cancer) one consisted of 45 lesions. For transrectal contrast- enhanced ultrasound was utilized ultrasound diagnostic system Epiq 5 (Philips, Netherlands) with a 4-10 MHz intracavitary probe and ultrasound contrast agent Sonovue (Bracco Swiss SA, Switzerland). With time-intensity curve analysis the following indices (the ratio of the absolute parameter value in the region of interest to the value of same parameter in the reference region) were assessed: WIR (wash-in rate) index, TTP (time to peak) index, PI (peak intensity) index, MTT (mean transit time) index, TPH (time from peak to one half) index, and RT (rise time) index. Results: Significant differences of WIR index (P &lt; 0.0001), PI index (P &lt; 0.0001), TTP index (P = 0.0008), and RT index (P = 0.0248) were obtained between the groups. The test “PI index &gt; 1.174 - prostate cancer” was characterized by sensitivity of 83.3%, specificity of 88.9%, positive predictive value of 83.3%, negative predictive value of 88.9%, and AUC of 0.910. The test “WIR index &gt; 1.432 - prostate cancer" was characterized by sensitivity of 76.7%, specificity of 82.2%, positive predictive value of 74.2%, negative predictive value of 84.1%, and AUC of 0.808. The test “TTP index &lt; 0.936 - prostate cancer" was characterized by sensitivity of 73.3%, specificity of 66.7%, positive predictive value of 59.5%, negative predictive value of 78.9%, and AUC of 0.729. A significant moderate correlation was determined between the Gleason sum and the PI index (rS = 0.394, P = 0.0311). Conclusions: The use of relative parameters (indices) for quantitative transrectal contrast-enhanced ultrasound can improve the accuracy of targeted biopsies in the diagnosis of prostate cancer. The indices show better diagnostic accuracy than absolute quantitative parameters of quantitative transrectal contrast-enhanced ultrasound.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ультразвуковое исследование с контрастным усилением</kwd><kwd>количественный анализ</kwd><kwd>количественные относительные параметры</kwd><kwd>индексы</kwd><kwd>перфузия</kwd><kwd>предстательная железа</kwd><kwd>рак предстательной железы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>contrast-enhanced ultrasound (CEUS)</kwd><kwd>quantitative analysis</kwd><kwd>relative quantitative parameters</kwd><kwd>indices</kwd><kwd>perfusion</kwd><kwd>prostate</kwd><kwd>prostate cancer</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">Bray F., Ferlay J., Soerjomataram I., Siegel R.L., Torre L.A., Jemal A.
