Изучить изменение экспрессии фактора неоангиогенеза VEGF в ткани опухоли при проведении таргетной терапии цетуксимабом и химиотерапии у больных плоскоклеточным раком слизистой оболочки полости рта.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. Было проведено иммуногистохимическое исследование образцов опухолевой ткани, полученных от 60 больных с плоскоклеточным раком слизистой оболочки полости рта T3-4N0-1M0. Основную группу составили 30 пациентов, которым была проведена лекарственная терапия препаратами цисплатин и фторурацил с добавлением цетуксимаба. Контрольную группу также составили 30 больных, которые подвергались стандартной химиотерапии без таргетной терапии. По степени эффективности каждая из исследуемых групп была поделена на две подгруппы: по чувствительности к лечению (n = 17 в группе с цетуксимабом и n = 12 в группе без цетуксимаба) и по резистентности к лечению (n = 13 в группе с таргетной терапией и n = 18 в группе со стандартной химиотерапией).</p></sec><sec><title>Результаты</title><p>Результаты. При количественной оценке экспрессии VEGF было выявлено, что минимальное количество сосудов, эндотелий которых окрашен данным маркером в поле зрения, наблюдалось у пациентов основной группы с чувствительностью к ХТ и цетуксимабу. Данный показатель был ниже в 5,3 раза по сравнению с исходными значениями и в 4,3 раза по сравнению с подгруппой пациентов, у которых наблюдалась резистентность к данному лечению (данные статистически значимы р = 0,0132 и р = 0,0455, соответственно). Что касается контрольной группы, то было отмечено, что при чувствительности к проводимому лечению значения были в 1,4 раза ниже исходных цифр (р = 0,921), а при резистентности – в 1,1 раза ниже относительно исходных цифр (р = 0,936). Данные оказались статистически не значимы.</p></sec><sec><title>Заключение</title><p>Заключение. В ходе исследования нами выявлено, что при наличии резистентности к химиотерапии и цетуксимабу количество сосудов в микроциркуляторном русле было в 4,3 раза выше по сравнению с больными, у которых наблюдался эффект от таргетной терапии (р = 0,0455). В контрольной группе значения оказались статистически незначимыми. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. An analysis of changes in the expression of the VEGF neoangiogenic factor in the tumor tissue of patients with squamous cell carcinoma of the oral mucosa receiving targeted therapy with cetuximab and chemotherapy.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. We performed an immunohistochemical study of tumor samples obtained from 60 patients with squamous cell carcinoma of the oral mucosa T3-4N0-1M0. The main group comprised 30 patients who received therapy with cisplatin and fluoruracil plus cetuximab. The control group included 30 patients receiving standard chemotherapy without targeted therapy. Each group was divided into two subgroups with different treatment efficacy: patients sensitive to treatment (n = 17 in the group with cetuximab and n = 12 in the group without cetuximab) and resistant to treatment (n = 13 in the group with targeted therapy and n = 18 in the group with standard chemotherapy).</p></sec><sec><title>Results</title><p>Results. Quantification of the VEGF expression demonstrated minimal numbers of vessels stained positively for this marker in the field of view in patients of the main group sensitive to chemotherapy and cetuximab. The value was 5.3 times lower than initial values, and 4.3 times lower than in the subgroup of patients resistant to the treatment (the data were statistically significant, р = 0.0132 and р = 0.0455, respectively). In the control group, patients who were sensitive to the treatment showed 1.4 times lower values than initially (р = 0.921), and patients who were resistant to the treatment had 1.1 times lower values than initial values (р = 0.936). The data were not statistically significant.</p></sec><sec><title>Conclusions</title><p>Conclusions. The study showed that the number of microvessels in patients resistant to chemotherapy and cetuximab was 4.3 times higher than in patients with effective targeted therapy (р = 0.0455). The differences in the control group were not statistically significant.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>плоскоклеточный рак слизистой оболочки полости рта</kwd><kwd>чувствительность</kwd><kwd>резистентность</kwd><kwd>VEGF</kwd><kwd>неоангиогенез</kwd><kwd>таргетная терапия</kwd><kwd>цетуксимаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oral squamous cell cancer</kwd><kwd>sensitivity</kwd><kwd>resistance</kwd><kwd>VEGF</kwd><kwd>neoangiogenesis</kwd><kwd>targeted therapy</kwd><kwd>cetuximab</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">Mohideen K, Krithika C, Jeddy N, Balakrishnan T, Bharathi R, Sankari SL.
