The patients were divided into four groups: group 1 included 29 women with endometrial adenocarcinoma, group 2 included 31 patients with endometrial polyp, group 3 included 10 women with endometrial hyperplasia, and the comparison group consisted of 25 healthy women. Blood plasma was analyzed via SERS, with three Raman spectra recorded per sample. Spectral measurements of the SERS substrate were assessed using dried samples on an experimental bench equipped with the spectrometric system RL785 (LLC “Foton-Bio”, Russia), incorporating a CCD detector, laser radiation source with a wavelength of 785 nm, and ADF U300 microscope (ADF, China). A silver substrate composed of dried silver colloid was used to demonstrate the enhancement effect on the Raman signal from the surface of the blood plasma.</p> <p><bold>Results. </bold>Spectral and specific features that distinguish adenocarcinoma, polyps, and endometrial hyperplasia were identified and evaluated. Spectral and quantitative differences specific to each condition, which are crucial for the differential diagnosis of pathologic tissues, were also identified. The accuracy rates of the optical diagnostics in distinguishing endometrial adenocarcinoma from the control group and endometrial hyperplasia were 87% and 85%, respectively, for the calibration and verification spectral sets (where the sensitivity and specificity were 66% and 92% for the spectral verification set, respectively). The accuracy rates of distinguishing control from endometrial hyperplasia and endometrial adenocarcinoma were 86% and 85%, respectively, and the accuracy of distinguishing endometrial hyperplasia from control and endometrial adenocarcinoma was 81% for the calibration and verification sets of spectra. In addition, the study demonstrated improved accuracy in differentiating adenocarcinoma from hyperplasia, including polyps. The accuracy rate was 93% in the calibration set of spectra, with sensitivity and specificity of 96% and 90%, whereas in the validation set, it was 91%, with sensitivity and specificity of 93% and 88%, respectively.</p> <p><bold>Conclusions. </bold>The study demonstrated the potential use of SERS for differentiating expression patterns in endometrial cancer from those in benign conditions.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Цель исследования ― повышение эффективности ранней диагностики рака эндометрия у женщин и усовершенствование дифференциальной диагностики доброкачественных заболеваний и рака эндометрия с помощью анализа поверхностно-усиленного рамановского рассеяния плазмы крови.</p> <p><bold>Материалы и методы. </bold>Проведено исследование плазмы крови пациенток в возрасте 22–79 лет. В исследование включили 95 женщин. Всех пациенток разделили на 4 группы: в 1-ю группу вошли 29 женщин с аденокарциномой эндометрия, во 2-ю ― 31 пациентка с полипом эндометрия, в 3-ю ― 10 женщин с гиперплазией эндометрия; группу сравнения составили 25 здоровых женщин. Исследование плазмы крови проводили с помощью спектроскопии поверхностно-усиленного рамановского рассеяния (SERS ― surface-enhanced Raman spectroscopy). Для каждого исследуемого образца плазмы крови фиксировали 3 спектра рамановского рассеяния. Спектральные значения исследуемого SERS-субстрата c высушенными образцами оценивали на экспериментальном стенде, состоящем из спектрометрической системы RL785 («Фотон-Био», Россия) на основе ПЗС-детектора, источника лазерного излучения с длиной волны 785 нм и микроскопа ADF U300 (ADF, Китай). С целью реализации эффекта поверхностного усиления рамановского сигнала от плазмы крови мы применили серебряный субстрат на основе высушенного коллоида серебра.</p> <p><bold>Результаты.</bold> Авторы выполнили оценку и определили спектральные особенности и специфические признаки, характерные для аденокарциномы, полипов и гиперплазии эндометрия. Выявлены спектральные и количественные отличия для каждой патологии, необходимые для дифференцированной диагностики патологических тканей. Точность оптической диагностики при разделении классов аденокарциномы эндометрия относительно контрольной группы и гиперплазии эндометрия для калибровочного и проверочного набора спектров составила 87 и 85%, соответственно (чувствительность 66%, специфичность 92% для проверочного набора спектров). Точность разделения классов контрольной группы относительно гиперплазии и аденокарциномы эндометрия составили 86 и 85%, а гиперплазии эндометрия относительно контрольной группы и аденокарциномы эндометрия ― 81% для калибровочного и проверочного наборов спектров. Кроме этого, показано, что точность дифференциации аденокарциномы возрастает при разделении классов аденокарциномы и гиперплазии, включая полипы, и составила 93% для калибровочного набора спектров (чувствительность 96%, специфичность 90%) и 91% для проверочного набора (чувствительность 93%, специфичность 88%).</p> <p><bold>Заключение.</bold> Проведённое исследование показало возможность использования поверхностно-усиленной рамановской спектроскопии для дифференциальной экспресс-диагностики рака эндометрия и доброкачественных патологических состояний.</p></trans-abstract><kwd-group xml:lang="en"><kwd>adenocarcinoma</kwd><kwd>blood plasma</kwd><kwd>discriminant analysis</kwd><kwd>latent structure projection</kwd><kwd>polyp</kwd><kwd>hyperplasia</kwd><kwd>surface-enhanced Raman spectroscopy (SERS)</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>плазма крови</kwd><kwd>полип</kwd><kwd>гиперплазия</kwd><kwd>аденокарцинома</kwd><kwd>поверхностно-усиленная рамановская спектроскопия (SERS)</kwd><kwd>метод проекций на латентные структуры</kwd><kwd>метод дискриминантного анализа</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Sulima AN, Kolesnikova IO, Davydova AA, Kriventsov MA.
