Изучить пролиферативную активность немелкоклеточного рака легкого при распространении опухоли по воздушным пространствам.Материалы и методы. В исследование включены 88 пациентов с немелкоклеточным раком легкого стадии IА-IIIA. Оценивался операционный материал. Гистологическое и иммуногистохимическое исследование выполнялись по стандартной методике. Применялись антитела к Ki67 (клон SP6, Cell Marque). В оцифрованных препаратах с применением автоматизированной системы Pannoramic MIDI с программным обеспечением Slide Viver V2.8. и многомодульной платформы Quant Center (3D HISTECH, Венгрия) подсчитывалась доля клеток (%) с позитивной ядерной экспрессией Ki67 в опухоли в целом и в зоне распространения по воздушным пространствам. Статистическая обработка проводилась с применением пакета программ Statistica 10.0. Статистически значимыми считали различия при р &lt; 0,05.Результаты. Экспрессия Ki67 (%) в ткани первичного опухолевого узла была выше в случаях с наличием распространения опухоли по воздушным пространствам, в том числе и при стадии IА аденокарциномы легкого. Экспрессия Ki67 (%) в зоне распространения опухоли по воздушным пространствам была выше в сравнении с экспрессией в опухоли в целом. Более высокая пролиферативная активность в зоне распространения опухоли по воздушным пространствам наблюдалась в случаях с обширным распространением в сравнении со случаями с ограниченным вариантом распространения по воздушным пространствам.Заключение. Полученные результаты дополняют сведения о механизмах распространения опухоли по воздушным пространствам как формы инвазивного роста и одного из вариантов опухолевой прогрессии, характерного для рака легкого.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To study the proliferative activity of non-small cell lung cancer with tumor spread through air spaces.Materials and methods. The study included 88 patients with stage IA-IIIA non-small cell lung cancer. The operative material was evaluated. Histologic and immunohistochemical examination was performed according to the standard technique. Antibodies to Ki67 (clone SP6, Cell Marque) were used. On digitized preparations using automated system Pannoramic MIDI with software Slide Viver V2.8. and multi-module platform Quant Center (3D HISTECH, Hungary) we counted the percentage of cells with positive nuclear expression of Ki67 in the tumor as a whole and in the area of spreading. Statistical processing was performed using the STATISTICA 10.0 software package. Differences at p &lt; 0.05 were considered statistically significant.Results. The percentage of Ki67 expression in the tissue of the primary tumor node was higher in cases with the presence of tumor spread through air spaces, including stage IA lung adenocarcinoma. The percentage of Ki67 expression in the area of air space spread of the tumor was higher compared to the percentage of expression in the tumor as a whole. Higher proliferative activity in the zone of tumor air space spread was observed in cases with extensive spread compared to cases with a limited variant of air space spread.Conclusion. The results obtained complement the existing data on the mechanisms of tumor spread through air spaces as a form of invasive growth and one of the variants of tumor progression characteristic of lung cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак легкого</kwd><kwd>распространение по воздушным пространствам</kwd><kwd>пролиферативная активность</kwd><kwd>Ki67</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lung cancer</kwd><kwd>spread through air spaces</kwd><kwd>proliferative activity</kwd><kwd>Ki67</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">Han Y.B., Kim H., Mino-Kenudson M., Cho S., Kwon H.J., Lee K.R. et al.
