Granov Russian Scientific Center of Radiology and Surgical Technologies for the period from 2018 to 2022. The main group included 89 patients with morphologically confirmed diagnosis of the pancreatic cancer without metastases. The control group included 71 patient with the confirmed diagnosis of chronic pancreatitis. Vitamin D concentration was controlled prior to treatment.</p> <p><bold>Results</bold><bold>.</bold> The size of the tumor node with the location of pathological process in the head of the pancreas varied from 2.1 to 6.3 cm. In the subgroup of patients with tumor lesion of the head of the pancreas, decompression of biliary ducts due to mechanical jaundice was implemented in 43 (82.6 %) persons. When comparing the indicators of 25(ОН)D concentration, in 36 (69.2 %) patients of the main group, different degrees of fall of vitamin D concentration in blood plasma were found. Most often a pronounced deficit of vitamin D was diagnosed in patients with the tumor localized in the head of the pancreas (8 (15.9 % patients). Out of 37 patients with localization of the tumor node in the body/tail, 25 (67.5 %) persons demonstrated normal values of blood plasma vitamin D and 12 (13.4 %) – different degrees of decrease in vitamin D concentration. A marked deficit of vitamin D was diagnosed in 2 (16.6 %) patients, deficit of vitamin D – in 7 (58.3 %), insufficiency – in 3 (25 %). In the control group, decrease in vitamin D level was determine in 12 (16.9 %) patients. An apparent deficit of vitamin D was diagnosed in 3 (4.2 %) patients, deficit of vitamin D– in 4 (5.6 %), and insufficiency of vitamin D – in 7 (9.8 %); normal values were registered in 57 (80.2 %) persons.</p> <p><bold>Conclusions</bold><bold>.</bold> Taking into account the obtained data regarding a reliable association between the deficit and insufficiency of vitamin D and the cancer of the head of the pancreas as well as literature data, it is worthwhile to use this indicator as a marker of early detection of pancreatic cancer in risk group patients.</p> <preformat> </preformat></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Проанализировать уровни дегидрохолекальциферола у пациентов с различными формами злокачественных новообразований поджелудочной железы и хроническим панкреатитом. Раннее выявление злокачественных новообразований имеет важное практическое значение для улучшения результатов лечения.</p> <p><bold>Материалы и методы.</bold> В когортное исследование включены данные 160 пациентов, прошедших обследование и лечение в ФГБУ РНЦРХТ им акад. А.М. Гранова в период с 2018 по 2022 г. В основную группу включены 89 пациентов с морфологически подтвержденным диагнозом рака поджелудочной железы без метастазов. В группу контроля включен 71 пациент с установленным диагнозом хронического панкреатита. Контроль концентрации витамина D выполняли до начала лечения.</p> <p><bold>Результаты.</bold> Размер опухолевого узла при локализации патологического процесса в головке поджелудочной железы варьировался от 2,1 до 6,3 см. В подгруппе больных с опухолевым поражением головки поджелудочной железы декомпрессия желчных протоков в связи с механической желтухой была выполнена у 43 (82,6 %) человек. При сравнительной оценке показателей концентрации 25(ОН)D у 36 (69,2 %) человек основной группы установлены различные степени снижения концентрации витамина D в плазме крови. Наиболее часто выраженный дефицит витамина D диагностирован у пациентов с локализацией опухоли в головке поджелудочной железы (8 (15,9 %) больных). Из 37 пациентов с расположением опухолевого узла в теле/хвосте у 25 (67,5 %) определены нормальные значения уровня витамина D в плазме крови, а у 12 (13,4 %) – выявлены различные степени снижения концентрации витамина D. У 2 (16,6 %) больных диагностирован выраженный дефицит витамина D, у 7 (58,3 %) – дефицит витамина D, еще у 3 (25 %) – недостаточность. В контрольной группе исследования у 12 (16,9 %) пациентов определено снижение уровня витамина D. Выраженный дефицит витамина D диагностирован у 3 (4,2 %), дефицит витамина D – у 4 (5,6 %), а недостаточность витамина D – у 7 (9,8 %), нормальные значения данного показателя зарегистрированы у 57 (80,2 %) человек.</p> <p><bold>Выводы.</bold> Учитывая полученные нами данные о достоверной связи дефицита и недостаточности витамина D и раком головки поджелудочной железы, а также данные литературы, можно сделать предположение о перспективе использования данного показателя в качестве маркера раннего выявления ЗНО ПЖ у пациентов групп риска.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pancreatic cancer</kwd><kwd>chronic pancreatitis</kwd><kwd>early detection</kwd><kwd>vitamin D</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак поджелудочной железы</kwd><kwd>хронический панкреатит</kwd><kwd>раннее выявление</kwd><kwd>витамин D</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>American Cancer Society.
