The main objective of this study was to compare the survival advantage achieved with these options.</p> <p><bold>Materials and methods. </bold>As a result of a systematic search in the PubMed, ClinicalTrials.gov databases, as well as in the materials of international conferences American Society of Clinical Oncology and European Society for Medical Oncology data on the overall survival showed in 11 open randomized trials comparing different generation TKI monotherapy in TKI naïve EGFR mutated non-small-cell lung carcinoma (NSCLC), both in the general population and in subgroups including sex, age, mutational status, smoking status. Using the package netmeta for the programming language R, a network meta-analysis of the obtained data was carried out using a frequency framework.</p> <p><bold>Results. </bold>The 11 selected studies, including 3251 participants, had the following comparison groups: 6 studies (ENSURE, EURTAC, IPASS, NEJ002, OPTIMAL CTONG-0802, WJTOG3405) compared 1st generation TKIs and standard platinum-based drugs (CT); 2 studies (LUX-Lung 3, LUX-Lung 6) compared 2nd generation TKIs and CT; 2 studies (ARCHER 1050, LUX-Lung 7) compared 2nd generation TKIs and 1st generation TKIs; one study (FLAURA) compared 3rd generation TKI and the 1st generation TKIs. It was shown that for overall survival in comparison with CT, 3rd generation TKIs [hazard ratio – HR 0.84 (0.64; 1.08) and 2nd generation (HR 0.86 (0.74; 1.00)] have the same effectiveness. Subgroup analysis did not reveal significant differences in OS except for the subgroup of patients with a deletion in exon 19 of the EGFR gene, where the use of 2nd generation TKIs in comparison with CT had a statistically significant difference – HR 0.71 (0.37; 0.97).</p> <p><bold>Conclusions. </bold>The network meta-analysis of the overall survival data of clinical trials of the use of different generations TKIs as the first line treatment in patients with EGFR-associated NSCLC showed that the use of TKIs of the 3rd and 2nd generation has the same efficacy, and the TKIs of the 2nd generation increase the total survival in a group of patients carrying a mutation in exon 19 of the EGFR gene.</p></abstract><trans-abstract xml:lang="ru"><p>Наличие противоречивых результатов, а также отсутствие прямых сравнительных рандомизированных исследований между ингибиторами тирозинкиназы EGFR II и III поколений в 1-й линии лечения пациентов с распространенным EGFR-ассоциированным немелкоклеточным раком легкого (НМРЛ) определило необходимость сравнения общей выживаемости (ОВ) для таких опций в рамках сетевого метаанализа.</p> <p><bold>Материалы и методы. </bold>В результате систематического поиска в базах данных PubMed, ClinicalTrials.gov, а также в материалах международных конференций Американского общества клинической онкологии и Европейского общества медицинской онкологии были отобраны данные по ОВ (отношение рисков – ОР смерти и 95% доверительный интервал – ДИ к нему) 11 рандомизированных исследований, в которых проводился анализ применения монотерапии ингибиторами тирозинкиназы (ИТК) разных поколений в качестве 1-й линии у пациентов с распространенным EGFR-ассоциированным НМРЛ, как для общей популяции, так и для подгрупп, включающих пол, возраст, мутационный статус, статус курения. С помощью пакета netmeta для языка программирования R был проведен сетевой метаанализ полученных данных с использованием частотного подхода.</p> <p><bold>Результаты. </bold>Критериям включения соответствовали 11 исследований, включавших 3251 пациента. Выделены следующие группы сравнения: в 6 исследованиях (ENSURE, EURTAC, IPASS, NEJ002, OPTIMAL CTONG-0802, WJTOG3405) – сравнение ИТК I поколения и стандартной химиотерапии (ХТ) на основе препаратов платины; в 2 исследованиях (LUX-Lung 3, LUX-Lung 6) – сравнение ИТК II поколения и ХТ; в 2 исследованиях (ARCHER 1050, LUX-Lung 7) – сравнение ИТК II поколения и ИТК I поколения; в 1 исследовании (FLAURA) – сравнение ИТК III поколения и ИТК I поколения. В сравнении с ХТ ОВ увеличивалась одинаково при применении ИТК III поколения (ОР 0,84; 95% ДИ 0,64–1,08) или II поколения (ОР 0,86; 95% ДИ 0,74–1,00). При этом анализ подгрупп не выявил существенных различий в ОВ за исключением подгруппы пациентов с делецией в экзоне 19 гена EGFR, где применение ИТК II поколения было более эффективным (ОР 0,71; 95% ДИ 0,37–0,97).</p> <p><bold>Выводы. </bold>Проведенный сетевой метаанализ данных ОВ клинических исследований применения ИТК разных поколений в качестве 1-й линии терапии у пациентов с EGFR-ассоциированным НМРЛ показал, что применение ИТК III и II поколения имеет одинаковую эффективность, при этом ИТК II поколения достоверно увеличивают ОВ в группе пациентов, несущих мутацию в экзоне 19 гена EGFR.</p></trans-abstract><kwd-group xml:lang="en"><kwd>non-small-cell lung carcinoma</kwd><kwd>EGFR</kwd><kwd>tyrosine kinase inhibitors</kwd><kwd>overall survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>немелкоклеточный рак легкого</kwd><kwd>EGFR</kwd><kwd>ингибиторы тирозинкиназы</kwd><kwd>общая выживаемость</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Siegel RL, Miller KD, Jemal A.
