Роль онкомаркеров как показателей рецидива, а также взаимосвязь распространенности заболевания при ПЭТ/КТ с 68Ga-DOTATATE и уровнями онкомаркеров изучена в единичных публикациях.</p></sec><sec><title>ЦЕЛЬ</title><p>ЦЕЛЬ: Определить значение онкомаркеров и лучевых методов исследования при динамическом наблюдении больных с НЭО ПЖ.</p></sec><sec><title>МАТЕРИАЛЫ И МЕТОДЫ</title><p>МАТЕРИАЛЫ И МЕТОДЫ: ПЭТ/КТ с 68Ga-DOTATATE выполнена у 73 пациентов с диагнозом НЭО ПЖ: 57 пациентов (78%) получали лечение ранее, у 16 пациентов (22%) проводилось первичное стадирование. Изучены уровни серотонина и хромогранина-А (ХгА) на момент ПЭТ/КТ и на момент начала заболевания, а также МСКТ и МРТ-архивы, выполненные в течение 2 мес до ПЭТ/КТ. Статистика: Для корреляций использовали коэффициент Спирмана. Для определения уровней онкомаркеров, при которых рекомендуется назначать ПЭТ/КТ с 68Ga-DOTATATE, проведен ROC-анализ. Результат ROC-анализа представлен с 95% доверительным интервалом.</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ: При МСКТ и МРТ метастазы диагностированы у 45 пациентов (61,6%), при ПЭТ/КТ очаги выявлены у 56 пациентов (76,7%), из них у 13 человек отмечены метастазы других анатомических локализаций, поражение которых не было выявлено ранее. Чувствительность ПЭТ/КТ с 68Ga-DOTATATE к НЭО ПЖ — 94,8%, специфичность — 93,3%. При ROC-анализе площадь под кривой составила для cеротонина 0,8 (ДИ 95% 0,676–0,924), для ХгА 0,81 (ДИ 95% 0,695– 0,925). Отмечена слабая взаимосвязь между степенью повышения онкомаркеров и числом очагов: для серотонина r=0,32 (p&lt;0,05), для ХгА r=0,298 (p&lt;0,05). Не выявлено корреляции между числом очагов и индексом пролиферативной активности опухоли (Ki67). Также для всех локализаций очагов не выявлено зависимости SUV max от уровней маркеров и Ki67.</p></sec><sec><title>ОБСУЖДЕНИЕ</title><p>ОБСУЖДЕНИЕ: В нашем исследовании ПЭТ/КТ с 68Ga-DOTATATE выявила больше метастазов, чем рутинные методы, благодаря этому скорректирован план лечения и объемы оперативных вмешательств. Повышение уровней онкомаркеров с большой долей вероятности свидетельствует о рецидиве заболевания. Однако низкий коэффициент корреляции Спирмана между числом очагов и уровнями серотонина и ХгА не позволяет достоверно предположить распространенность опухолевого процесса по величине этого подъема. Также не выявлено значимой взаимосвязи между распространенностью опухоли и уровнями исследуемых онкомаркеров.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ: ПЭТ/КТ с 68Ga-DOTATATE обладает более высокой точностью в диагностике НЭО ПЖ, чем рутинные методы визуализации. В сочетании с определением уровней онкомаркеров повышается вероятность обнаружения опухолевых очагов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>INTRODUCTION</title><p>INTRODUCTION: Follow-up of patients with pancreatic neuroendocrine tumors (p-NETs) remains little studied and relevant. The role of tumor markers as indicators of recurrence, as well as the relationship between the prevalence of the disease in 68Ga-DOTATATE PET/CT and levels of tumor markers, has been studied in a few publications.</p></sec><sec><title>OBJECTIVE</title><p>OBJECTIVE: To determine the significance of markers and visualization methods in the follow-up of patients with p-NETs.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: 68Ga-DOTATATE PET/CT was performed in 73 patients diagnosed with pancreatic NET: 57 patients (78%) were previously treated, 16 patients (22%) underwent primary staging. The levels of serotonin and chromogranin-A (CgA) were studied at the time of PET/CT and at the onset of the disease. CT and MRI were performed within 2 months before PET/CT. Statistics: Spearman’s coefficient was used for correlations. To determine the levels of markers at which it is recommended to enroll 68Ga-DOTATATE PET/CT, a ROC-analysis was performed. The result of the ROC-analysis is presented with a 95% confidence interval.</p></sec><sec><title>RESULTS</title><p>RESULTS: CT and MRI revealed metastases in 45 patients (61.6%), PET/CT revealed foci in 56 patients (76.7%), of which 13 patients had metastases of other anatomical locations, which were not previously detected. Sensitivity of 68Ga-DOTATATE PET/CT to pancreatic NET is 94.8%, specificity is 93.3%. In ROC-analysis, the area under the curve was 0.8 for serotonin (CI95% 0.676–0.924), for CgA 0.81 (CI95% 0.695–0.925). A weak relationship was revealed between the degree of oncomarkers increase and the number of foci: for serotonin r=0.32 (p&lt;0.05), for CgA r=0.298 (p&lt;0.05). No correlation was found between the number of foci and the tumor proliferative activity index (Ki67). Also, for all foci localizations, there was no dependence of SUV max on the levels of markers and Ki67.</p></sec><sec><title>DISCUSSION</title><p>DISCUSSION: In our study, 68Ga-DOTATATE PET/CT revealed more metastases than routine methods, due to this, the treatment plan and the volume of surgical interventions were adjusted. An increase in the levels of tumor markers highly likely indicates a relapse of the disease. However, the low Spearman correlation coefficient between the number of foci and the levels of serotonin and CgA does not allow us to assume the prevalence of the tumor process by the degree of this rise. In addition, no significant relationship was found between the prevalence of the tumor and the levels of the studied tumor markers.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: 68Ga-DOTATATE PET/CT has higher accuracy in the diagnosis of p-NETs than routine imaging methods. In combination with the determination of the tumor markers levels, the probability of detecting tumor foci increases.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейроэндокринная опухоль</kwd><kwd>поджелудочная железа</kwd><kwd>ПЭТ/КТ</kwd><kwd>68Ga-DOTATATE</kwd><kwd>серотонин</kwd><kwd>хромогранин-А</kwd><kwd>ROC-анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neuroendocrine tumor</kwd><kwd>pancreas</kwd><kwd>PET/CT</kwd><kwd>68Ga-DOTATATE</kwd><kwd>serotonin</kwd><kwd>chromogranin-A</kwd><kwd>ROC-analysis</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">Gordon-Dseagu V.L., Devesa S.S., Goggins M., Stolzenberg-Solomon R.
