Выявление лиц с высоким онкологическим риском развития плоскоклеточного рака области головы и шеи (ПРГШ) является актуальной проблемой для ранней диагностики этого заболевания. Критерием для прогноза риска возникновения ПРГШ у больных с предопухолевыми заболеваниями верхних отделов респираторного и желудочно-кишечного трактов может быть активность циркулирующих протеасом.</p><p>Цель исследования – изучить химотрипсинподобную и каспазаподобную активности циркулирующих протеасом сыворотки крови в зависимости от локализации предопухолевых и опухолевых заболеваний гортани и ротовой полости.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование вошли 35 пациентов с ПРГШ (T1–3N0–3M0) с гистологически верифицированным диагнозом, 15 человек с хроническим гиперпластическим ларингитом (ХГЛ с dIIII), лейкоплакиями полости рта и 10 здоровых волонтеров, не имеющих хронических заболеваний верхних дыхательных путей в стадии обострения.

Обнаружено повышение изучаемых активностей протеасом в сыворотке крови больных со злокачественной опухолью по сравнению с больными хроническими гиперпластическими заболеваниями, ассоциированными с предопухолевыми изменениями, а  также в группах ПРГШ по сравнению со здоровыми  донорами. В то же время в зависимости от локализации патологического процесса показано, что только химотрипсинподобная (ХТП) активность циркулирующего пула протеасом значимо различается как в группах рак ротовой полости – лейкоплакии, так и в группах рак гортани – хронический гиперпластический ларингит (ХГЛ) с диспластическими изменениями эпителия. Кроме того, были обнаружены различия между ХТП и каспазаподобной активностями циркулирующих протеасом сыворотки крови больных хроническим гиперпластическим ларингитом с дисплазиями и лейкоплакиями ротовой полости, а также у групп больных злокачественными опухолями этих локализаций.</p></sec><sec><title>Выводы</title><p>Выводы. Полученные результаты свидетельствуют о том, что определение ХТП активности циркулирующего пула  протеасом может быть использовано в качестве критерия  для прогноза риска возникновения ПРГШ у больных  предопухолевыми заболеваниями гортани и ротовой полости. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title> Introduction</title><p> Introduction. Identification of persons with a high oncological risk to squamous cell carcinoma of the head and neck region is an urgent problem for the early diagnosis of this disease. The activity of circulating proteasomes can be a criterion for predicting the risk of the larynx and oral cavity cancers in patients with precancerous diseases of the upper respiratory and gastrointestinal tracts. </p><p>The aim of the study is to investigate the chymotrypsin-like and caspase-like activities of circulating serum proteasomes depending on the localization of precancerous and neoplastic diseases of the larynx and oral cavity. </p></sec><sec><title>Material and Methods</title><p>Material and Methods. The study population consisted of 35 patients with histologically verified HNSCC (T1–3N0–3M0), 15 patients with chronic hyperplastic laryngitis (CHL) and oral leukoplakia, and 10 healthy volunteers  who did not have chronic upper respiratory tract diseases in the acute stage. The median age of the patients was 53 ± 5.3 years. </p></sec><sec><title>Results</title><p>Results. An increase in the studied proteasome activities was found in the blood serum of patients with malignant tumors as compared with patients with chronic hyperplastic diseases associated with precancerous changes, as well as in the larynx and oral cavity cancers groups as compared with healthy donors. At the same time, depending on the localization of the pathological process, it was shown that only the chymotrypsin-like activity of the circulating pool of proteasomes significantly differs both in the groups of oral cancer leukoplakia, and in the groups of laryngeal cancer chronic hyperplastic laryngitis with dysplastic epithelial lesions. In addition, differences were found between chymotrypsin-like and caspase-like activities of circulating serum proteasomes in patients with chronic hyperplastic laryngitis with oral dysplasia and leukoplakia. </p></sec><sec><title>Conclusion</title><p>Conclusion. The results obtained indicate that the determination of the CTp activity of the circulating pool of proteasomes can be used as a criterion for predicting the risk of the larynx and oral cavity cancers in patients with  precancerous diseases of the larynx and oral cavity. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак гортани</kwd><kwd>рак ротовой полости</kwd><kwd>дисплазия</kwd><kwd>химотрипсинподобная активность протеасом</kwd><kwd>каспазаподобная активность протеасом</kwd></kwd-group><kwd-group xml:lang="en"><kwd>laryngeal cancer</kwd><kwd>oral cancer</kwd><kwd>dysplasia</kwd><kwd>chymotrypsin-like activity of proteasomes</kwd><kwd>caspase-like activity of proteasomes</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках Государственного задания на 2021 г. в НИИ онкологии Томского НИМЦ.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was conducted within the framework of the State Assignment for 2021 at the Cancer Research Institute, Tomsk National Research Medical Center.</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">Кожанов А.Л.
