Оценить диагностические  характеристики  маркера   эпителиальных карцином СА‑62 при выявлении ранних стадий рака предстательной железы (РПЖ) в рамках   двойного   слепого клинического  исследования   и  изучить возможность использования   ракового антигена СА‑62 в качестве дополнительного инструмента для принятия решения   при  диагностике РПЖ.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. Слепое  клиническое исследование было   проведено  на 325 клинически верифицированных  образцах сыворотки крови  (144 больных РПЖ, 79 условно здоровых   добровольцев–мужчин и 102 больных с доброкачественной гиперплазией предстательной железы (ДГПЖ)). Количественное измерение   общего и свободного простат-специфического антигена  (ПСА), а также маркера  СА‑62 в образцах сыворотки  крови проводили   с использованием электрохемилюминесцентного  иммуноанализа ECLIA Elecsys Total и Free PSA (COBAS, Roche Diagnostics GmbH, Германия, ЕС) и хемилюминесцентного  иммуноанализа  ИХА‑СА‑62 (ООО «Джейвис Диагностикс,  Москва, РФ).</p></sec><sec><title>Результаты</title><p>Результаты. Сравнение    диагностических характеристик маркера   СА‑62 с общим   и свободным ПСА, а также   с другими методами диагностики  (prostate cancer antigen (PCA3), индекс  здоровья простаты (ИЗП)) показало,  что маркер СА‑62 обладает наиболее высокими  значениями прогностической  ценности положительного результата  (PPV 94,4 %) и прогоностической ценности отрицательного результата (NPV 93,1 %). Это может повысить достоверность принятия решения о наличии РПЖ и использоваться врачами  в качестве аргумента для  необходимости   проведения   пациенту  биопсии предстательной железы. Показано, что применение нового онкомаркера   СА‑62 позволяет выявлять до  90 % ранних  стадий РПЖ   при 97,2 % специфичности (AUC = 0,969).</p></sec><sec><title>Заключение</title><p>Заключение.

Evaluation of the diagnostic characteristics of the CA‑62 marker for epithelial carcinomas for detecting early‑stage prostate cancer in a double‑blind clinical study. This study is also focused on the possibility of using the CA‑62 antigen as an auxiliary tool for decision‑making in prostate cancer diagnosis.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A blinded clinical study was conducted on 325 clinically verified blood serum samples. This includes 144 prostate cancer samples, 79 generally healthy volunteers‑men and 102 samples from patients with benign prostatic hyperplasia (BPH). Quantitative determination of the total and free prostate specific antigen (PSA) levels, as well as the CA‑62 marker of serum samples was performed using the electrochemiluminescent immunoassay ECLIA Elecsys Total and Free PSA (COBAS, Roche Diagnostics GmbH, Germany, EU) and the chemiluminescent immunoassay CLIA‑CA‑62 (JVS Diagnostics LLC, Moscow, RF).</p></sec><sec><title>Results</title><p>Results. A comparison of the CA‑62 level with the results for total and free PSA, as well as other diagnostic methods (PCA3, PHI) for the analysis of the BPH and prostate cancer groups was performed. The results show that the CA‑62 marker has the highest PPV (94.4 %) and NPV (93.1 %). This may increase the reliability of the decision related to the presence of PC and be used by doctors as an argument as an argument for a prostate biopsy referral. It has been demonstrated that using the novel cancer marker CA‑62 makes it possible to detect up to 90 % of the early‑stage prostate cancer with 97.2 % specificity (AUC = 0.969).</p></sec><sec><title>Conclusion</title><p>Conclusion. Using the CA‑62 marker as an auxiliary diagnostic method within the PSA “grey zone” (from 2.5 to 10 ng/ml) made it possible to significantly increase the accuracy of detecting the PC early stages at biopsy up to 93.1 %. It will help the doctors to effectively differentiate between prostate cancer and benign prostatic hyperplasia.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>онкомаркер</kwd><kwd>рак предстательной железы</kwd><kwd>доброкачественная гиперплазия предстательной железы</kwd><kwd>простат‑специфический антиген</kwd><kwd>раковый антиген СА‑62</kwd><kwd>биопсия предстательной железы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cancer marker</kwd><kwd>prostate cancer</kwd><kwd>benign prostatic hyperplasia</kwd><kwd>prostate‑specific antigen</kwd><kwd>CA‑62 cancer antigen</kwd><kwd>prostate biopsy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена   при  финансовой   поддержке    Министерства науки и  высшего   образования Российской  Федерации   в рамках государственной поддержки создания  и  развития  научных  центров мирового   уровня «Цифровой биодизайн   и  персонализированное  здравоохранение»   № 075–15–2022–304.</funding-statement><funding-statement xml:lang="en">The study was conducted with funding of the Ministry of Science and Higher Education of the Russian Federation within the framework  of state support for the creation and development of World‑Class Research Centers «Digital bio design and personalized  healthcare» № 075‑15‑2022‑304.</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">International Agency for Research on Cancer.
