Длительное время считалось, что рак легкого — это болезнь курильщиков и его в значительной степени можно предотвратить путем ограничения употребления табака, однако недавние исследования продемонстрировали тревожный рост заболеваемости среди некурящих лиц обоего пола. Персонализированная медицина, включающая тщательное молекулярно-генетическое исследование, оптимизирует лечение каждого пациента и улучшает его качество жизни в процессе терапии.Предметом рассмотрения в данной статье является конкретный клинический случай эффективного применения осимертиниба — ингибитор тирозинкиназы рецептора эпидермального фактора роста (EGFR) третьего поколения (TKI), который широко применялся в качестве терапии первой линии у пациентов с метастатическим EGFR-мутантным немелкоклеточным раком легкого (НМРЛ), а в данное время показывает прекрасные результаты и в адъювантном режиме. Цель работы — проанализировать эффективность применения ингибитора тирозинкиназы рецептора эпидермального фактора роста (EGFR) третьего поколения (TKI) при аденокарциноме легкого на примере из клинической практики. В ходе обсуждения особенностей лечения пациентки с НМКРЛ используются результаты лабораторных исследований, данные различных методов диагностики и лечения.</p></abstract><trans-abstract xml:lang="en"><p>Lung cancer is the most common malignant neoplasm and ranks first in the structure of cancer mortality. Lung cancer has long been thought to be a smoker’s disease and largely preventable by limiting tobacco use, but recent studies have shown an alarming increase in the incidence of the disease among non-smokers of both sexes. Personalized medicine, including careful molecular genetic testing, optimizes treatment for each patient and improves their quality of life during therapy.The subject of this article is a specific clinical case of the effective use of Osimertinib, a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), which has been widely used as first-line therapy in patients with metastatic EGFR-mutant non-small cell lung cancer (NSCLC), and currently shows excellent results in the adjuvant mode. The aim of the work is to analyze the effectiveness of the use of the third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) in lung adenocarcinoma using an example from clinical practice. During the discussion of the specifics of treatment of a patient with NSCLC, the results of laboratory tests, data from various diagnostic and treatment methods are used.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак легкого</kwd><kwd>таргетная терапия</kwd><kwd>качество жизни</kwd><kwd>осимертиниб</kwd><kwd>комплексное лечение</kwd><kwd>аденокарцинома легкого</kwd><kwd>диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lung cancer</kwd><kwd>targeted therapy</kwd><kwd>quality of life</kwd><kwd>osimertinib</kwd><kwd>complex treatment</kwd><kwd>lung adenocarcinoma</kwd><kwd>diagnostics</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">Thai А.А., Solomon B.J., Sequist L.V.
