Определить частоту и сочетание с основными соматическими драйверами герминальной мутации СHEK2 p.Ile157Thr у пациентов с немелкоклеточным раком легкого (НМРЛ) в Республике Татарстан.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. Панельное NGS-секвенирование ключевых онкогенов выполнено в опухолевом материале 151 пациента. Библиографический поиск проводился вручную в Google Scholar, PubMed по сочетаниям «CHEK2 I157T», «p.Ile157Thr», «c.470T&gt;C», «NSCLC», «germline», «NGS» и др.; формулировки уточнялись с помощью искусственного интеллекта при обязательной ручной вери‑ фикации. Статистическую обработку выполняли в SPSS v18.0; для сравнения долей применяли точный критерий Фишера, уровень значимости p &lt; 0,05).</p></sec><sec><title>Результаты</title><p>Результаты. Вариант p.Ile157Thr выявлен у 12 (7,9 %) пациентов: у 100 % подтверждена гистологически аденокарцинома. Семейный анамнез злокачественных опухолей зафиксирован у 2 (16,7 %) пациентов, множественные первичные новообразования – у 2 (16,7 %). Сопутствующие драйверные мутации обнаружены у 8 (66,7 %): EGFR – у 5 (62,5 %), у 3 (37,5 %) была обнаружена одна из мутаций KRAS (12,5 %), NRAS и BRAF соответственно. У 4 (33,3 %) p.Ile157Thr было единственным молекулярным событием. При сравнении носителей и неносителей CHEK2 p.Ile157Thr по стадиям заболевания и частоте сопутствующих драйверов статистически значимых различий не выявлено (точный критерий Фишера, p &gt; 0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Герминальный вариант CHEK2 p.Ile157Thr (c.470T&gt;C) выявлен у части пациентов с аденокарциномой легкого и в ряде случаев сочетался с соматическими драйверными мутациями. Полученные данные уточняют его частоту в исследуемой популяции и описывают молекулярные особенности опухолей у носителей, что может быть использовано в дальнейших исследованиях кли‑ нического значения CHEK2 при НМРЛ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To determine the frequency and co-occurrence with major somatic drivers of the germline CHEK2 p.Ile157Thr mutation in patients with non-small cell lung cancer (NSCLC) in the Republic of Tatarstan.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. Targeted next-generation sequencing (NGS) of key oncogenes was performed on tumor tissue from 151 patients. A bibliographic search was carried out manually in Google Scholar and PubMed using the terms “CHEK2 I157T,” “p.Ile157Thr,” “c.470T&gt;C,” “NSCLC,” “germline,” “NGS,” among others; search formulations were refined with the aid of artificial intelligence, followed by mandatory manual verification. Statistical analysis was performed in SPSS v18.0. Proportions were compared using Fisher’s exact test with a significance threshold of p &lt; 0.05.</p></sec><sec><title>Results</title><p>Results. The p.Ile157Thr variant was identified in 12 patients (7.9 %); all cases (100 %) were histologically confirmed adenocarcinomas. A positive family history of malignant tumors was recorded in 2 patients (16.7 %), and multiple primary malignancies in 2 patients (16.7 %). Concomitant driver mutations were detected in 8 patients (66.7 %): EGFR in 5 (62.5 %), while 3 patients (37.5 %) harbored mutations in KRAS (12.5 %), NRAS, and BRAF, respectively. In 4 patients (33.3 %), p.Ile157Thr was the sole molecular event. In a comparison of carriers versus non-carriers of CHEK2 p.Ile157Thr, no statistically significant differences were observed in stage distribution or in the frequency of co-occurring driver alterations (Fisher’s exact test, p &gt; 0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. The germline CHEK2 p.Ile157Thr (c.470T&gt;C) variant was identified in a subset of patients with lung adenocarcinoma and in several cases was accompanied by somatic driver mutations. The obtained data refine the frequency of this variant in the studied population and describe the molecular characteristics of tumors in carriers, providing a basis for further evaluation of the potential clinical relevance of CHEK2 in NSCLC.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>CHEK2</kwd><kwd>p.Ile157Thr</kwd><kwd>c.470T&gt;C</kwd><kwd>I157T</kwd><kwd>рак легкого</kwd><kwd>немелкоклеточный рак легкого</kwd><kwd>NGS</kwd><kwd>cеквенирование нового поколения</kwd><kwd>герминальные мутации</kwd><kwd>наследственные мутации</kwd></kwd-group><kwd-group xml:lang="en"><kwd>CHEK2</kwd><kwd>p.Ile157Thr</kwd><kwd>c.470T&gt;C</kwd><kwd>I157T</kwd><kwd>lung cancer</kwd><kwd>non-small cell lung cancer</kwd><kwd>NGS</kwd><kwd>next-generation sequencing</kwd><kwd>germline mutations</kwd><kwd>hereditary mutations</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">Wild CP, Weiderpass E, Stewart BW (eds).
