Целью исследования явилось изучение уровня экспрессии EGFR в ткани опухоли у больных плоскоклеточным раком языка и слизистой оболочки дна полости рта в зависимости от эффективности проводимой терапии. Материал и методы: В исследование были включены данные о 60 больных плоскоклеточным раком языка и слизистой дна полости рта T3-4N0-1M0. Основную группу составили 30 пациентов, которым проведен курс химиотерапии (цисплатин/фторурацил) в сочетании с таргетной терапией цетуксимабом. В контрольную группу вошли 30 пациентов с проведением курса химиотерапии без цетуксимаба. Обе группы были поделены на две подгруппы: с чувствительностью и резистентностью. Результаты: В ходе исследования при применении цетуксимаба в случае резистентности в основной группе среднее значение экспрессии EGFR было в 2 раза меньше относительно фоновых значений (р = 0,0080) и в 1,7 раза выше по сравнению с подгруппой резистентности в контрольной группе (р = 0,0157). В случае чувствительности среднее значение экспрессии EGFR было в 19,8 раза меньше (р = 0,0020) относительно фоновых значений и в 14,9 раза выше (р = 0,0067) по сравнению с подгруппой чувствительности в контроле. Выводы: Таким образом, выявлено закономерное снижение экспрессии EGFR в образцах ткани опухоли в результате применения таргетной терапии. Однако часть пациентов оказалась резистентной к цетуксимабу, что подтверждает необходимость поиска предикторов эффективности к таргетной терапии у больных местнораспространенным плоскоклеточным раком языка и слизистой оболочки дна полости рта.</p></abstract><trans-abstract xml:lang="en"><p>Introduction: Squamous cell carcinoma of the oral cavity is one of the most common head and neck cancers with an aggressive course and high mortality rates. The aim of the study was to determine the EGFR expression levels in tumor tissues in patients with squamous cell carcinoma of the tongue and oral mucosa depending on the efficacy of the therapy. Material and methods: The study included 60 patients with squamous cell carcinoma of the tongue and oral mucosa T3-4N0-1M0. The main group included 30 patients receiving chemotherapy (cisplatin/fluorouracil) in combination with targeted therapy with cetuximab. The control group included 30 patients receiving chemotherapy without cetuximab. Both groups were divided into two subgroups: sensitive and resistant. Results: In treatment-resistant patients of the main group with cetuximab, the average EGFR expression was twice lower than the initial levels (p = 0.0080) and 1.7 times higher than in treatment-resistant patients of the control group (p = 0.0157). In treatment-sensitive patients, the average EGFR expression was 19.8 times lower (p = 0.0020) than initial values and 14.9 times higher (p = 0.0067) than in treatment-sensitive controls.  Conclusions: A natural decrease in the EGFR expression in tumor tissues due to the targeted therapy was revealed. However,  some patients were resistant to cetuximab, which dictates the need to search for predictors of targeted therapy efficacy in patients with locally advanced squamous cell carcinoma of the tongue and oral mucosa.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак языка</kwd><kwd>рак слизистой оболочки дна полости рта</kwd><kwd>цетуксимаб</kwd><kwd>EGFR</kwd><kwd>чувствительность</kwd><kwd>резистентность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tongue cancer</kwd><kwd>cancer of the oral floor mucosa</kwd><kwd>cetuximab</kwd><kwd>EGFR</kwd><kwd>sensitivity</kwd><kwd>resistance</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">Leemans C.R., Snijders P.J.F., Brakenhoff R.H.
