У женщин мутации встречались в 3,8 раза чаще, чем у мужчин. У пациентов с I и II стадиями заболевания мутации выявлялись в 2,8 раза чаще, чем у пациентов c III и IV стадиями. У пациентов саха (якуты) частота мутаций в 3,4 раза выше, чем в этнической группе русские. У мужчин саха (якуты) частота мутаций гена EGFR в 9,6 раза выше, чем у мужчин в этнической группе русские. Показано, что при положительном статусе мутаций EGFR общая 36-месячная выживаемость пациентов увеличивается в 2,5 раза. Из них у пациентов с I и II стадиями заболевания выживаемость выше в 1,4, у пациентов до 65 лет в 2,9, у женщин в 2,4 раза.</p></abstract><trans-abstract xml:lang="en"><p>The frequency of Del 19 and L858R mutations of the EGFR gene was studied among patients of the Yakut Republican Oncology Dispensary with lung adenocarcinoma (n=177). Mutations were found 3.8 times more commonly in female population than in male. Mutations were detected 2.8 times more regularly among patients with stages I and II of the disease in compare with stages III and IV. The mutation frequency was 3.4 times over in the Sakha (Yakut) ethnic group patients as opposed to Russian ethnic group. In addition the mutation frequency was 9.6 times over in the Sakha (Yakut) ethnic group male patients as opposed to Russian ethnic group. It was shown that the overall 36-month survival of patients with a positive status of EGFR mutations increases by 2.5 times (from 29.3% to 74.1%). Moreover in patients with stages I and II of the disease, survival rate increases by 1.4 times, in patients over 65 years old in 2.9 times, in female patients in 2.4 times.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>немелкоклеточный рак легкого</kwd><kwd>аденокарцинома</kwd><kwd>мутации гена EGFR</kwd><kwd>выживаемость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>non-small cell lung cancer</kwd><kwd>adenocarcinoma</kwd><kwd>EGFR gene mutations</kwd><kwd>survival</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">Афанасьева Л.
