Материалы и методы. Проводили иммуногистохимическое исследование опухолевой ткани у больных серозным раком яичников высокой степени злокачественности IIIC–IV стадии в возрасте 49–72 лет, чувствительных (n=59) и резистентных (n=22) к платиносодержащим режимам адъювантной полихимиотерапии, у которых был отмечен положительный эффект на неоадъювантную терапию. В ткани опухолей яичников, полученной на этапе хирургического вмешательства после неоадъювантной полихимиотерапии, изучали иммуногистохимические показатели пролиферативной активности (Ki67), экспрессии белка эксцизионной репарации ДНК ERCC1 и белков семейства АВС-транспортеров – Pgp и BCRP, а также статистические связи между этими показателями (коэффициент ранговой корреляции Спирмена). Результаты. На этапе хирургического лечения после эффективной неоадъювантной полихимиотерапии в серозных карциномах яичников, продемонстрировавших в дальнейшем резистентность к платиносодержащим режимам полихимиотерапии, отмечены более выраженные признаки активности процессов пролиферации, репарации ДНК и эффлюкса ксенобиотиков по сравнению с опухолями, сохранившими платиночувствительность. При этом более чем в 40 % случаев наблюдалось совпадение диапазонов значений исследованных показателей в опухолях с различной чувствительностью к препаратам платины. Показано, что экспрессия белков-транспортеров, превышающая 60 % для BCRP и 65 % для Pgp, предшествует развитию резистентности к адъювантному лечению с карбоплатином. В исследуемых группах наблюдались различия по числу, направленности и выраженности статистических связей между изученными показателями. Наиболее значительные отличия отмечены для корреляционной связи Ki67 – BCRP, имевшей противоположную направленность в группах с различной чувствительностью к адъювантному лечению с карбоплатином. Заключение. Получена комплексная иммуногистохимическая характеристика серозных карцином яичников после неоадъювантной полихимиотерапии, продемонстрировавших впоследствии различную чувствительность к платиносодержащим режимам адъювантной полихимиотерапии, с оценкой прогностического значения изученных показателей. Прогностическое значение в отношении эффекта АПХТ могут иметь выявленные критические уровни экспрессии Pgp и BCRP в ткани опухоли. Результаты корреляционного анализа позволяют предполагать связь формирования платинорезистентности с изменением характера регуляторных отношений между пролиферативной активностью и транспортными процессами в ткани опухоли.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to evaluate a prognostic significance of immunohistochemical parameters in serous ovarian carcinomas and their statistical relationships after neoadjuvant treatment to assess the development of tumor resistance to platinum-containing adjuvant polychemotherapy regimens. Material and Methods. An immunohistochemical study of tumor tissue was carried out in patients with high-grade serous ovarian cancer (stage IIIC–IV). The age of the patients ranged from 49–72 years. There were 59 patients who were sensitive and 22 patients who were resistant to platinum-containing adjuvant polychemotherapy. In the tissue of ovarian tumors obtained during surgery after noadjuvant polychemotherapy, we studied immunohistochemical indicators of proliferative activity (Ki67), expression of the DNA excision repair protein ERCC1 and proteins of the ABC transporter family – Pgp and BCRP, as well as statistical relationships between these indicators (Spearman’s rank correlation coefficient). Results. After effective neoadjuvant polychemotherapy, more pronounced signs of activity in the processes of proliferation, DNA repair and xenobiotic efflux were noted in serous ovarian carcinomas, which subsequently demonstrated resistance to platinum-containing polychemotherapy regimens compared to tumors that retained platinum sensitivity. Moreover, in 40 % of cases or more, there was a coincidence in the ranges of values of the studied parameters in tumors with different sensitivity to platinum drugs. The expression of transporter proteins greater than 60 % for BCRP and 65 % for Pgp was shown to precede the development of resistance to adjuvant treatment with carboplatin. In the studied groups, differences in the number and significance of statistical relationships between the variables were observed. The most significant differences were noted for the Ki67 – BCRP correlation, which had the opposite direction in groups with different sensitivity to adjuvant treatment with carboplatin. Conclusion. A comprehensive immunohistochemical analysis of highgrade serous ovarian carcinomas after neoadjuvant polychemotherapy, which further demonstrated different sensitivity to platinum-containing adjuvant regimens, was carried out, and the prognostic value of the studied parameters was assessed. The revealed critical levels of Pgp and BCRP expression in tumor tissue may have a prognostic value regarding the effect of adjuvant polychemotherapy. The results of the correlation analysis suggest a relationship between the development of platinum resistance and changes in the nature of the regulatory relationships between proliferative activity and transport processes in tumor tissue.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>серозная карцинома яичников высокой степени злокачественности</kwd><kwd>платинорезистентность</kwd><kwd>пролиферация</kwd><kwd>транспортные белки</kwd><kwd>статистическая связь</kwd><kwd>биологическая обратная связь</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-grade serous ovarian cancer</kwd><kwd>platinum resistance</kwd><kwd>proliferation</kwd><kwd>transport proteins</kwd><kwd>statistical relationship</kwd><kwd>biofeedback</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">Молекулярно-генетические подтипы рака яичников: перспективы дальнейших исследований.
