Исследование было проведено в 2024–2025 гг. на базе кафедры болезней мелких домашних, лабораторных и экзотических животных ФГБОУ ВО «Российский биотехнологический университет (Росбиотех)». Объектом исследования являлись 40 собак с нерезектабельными саркомами мягких тканей неопределенного фенотипа в области головы, подтвержденными гистологически.</p><p>Цель работы — изучение влияния «Фирококсиба» в комплексной терапии нерезектабельных сарком мягких тканей с оценкой течения локального воспалительного процесса. В ходе исследования были сформированы 4 группы собак, в которых определяли объем пораженной ткани, степень воспаления, болевой синдром и скорость роста нерезектабельных злокачественных новообразований у собак. В трех группах применяли «Фирококсиб» в качестве нестероидного противовоспалительного препарата в сочетании с «Карбоплатином» (алкилирующим антинеопластическим препаратом), четвертая группа служила контролем (для животных в данной группе применяли «Карбоплатин» в монорежиме).</p><p>По результатам исследования было выявлено, что «Фирококсиб» снизил воспалительный компонент и степень болезненности в области локализации онкологического процесса, что позволило значительно улучшить качество жизни во всех трех группах собак по сравнению с контрольной, при этом побочных эффектов выявлено не было. Показано, что «Фирококсиб» значительно усиливает противоопухолевую активность «Карбоплатина» за счет купирования воспалительного процесса и предполагаемого частичного ингибирования развития опухоли, приводя к частичной ремиссии и увеличению общей выживаемости.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of long-term use of “Firocoxib” for the treatment and control of the inflammatory process in animals with a confirmed diagnosis of soft tissue sarcoma of an indeterminate phenotype in the head area. The study was conducted in 2024–2025 on the basis of the Department of Diseases of Small Domestic, Laboratory and Exotic Animals of the Russian Biotechnological University (Rosbiotech). The object of the study was 40 dogs with unresectable soft tissue sarcomas of an indeterminate phenotype in the head region, confirmed histologically.</p><p>The aim of the work was to study the effect of “Firocoxib” in the complex therapy of unresectable soft tissue sarcomas with an assessment of the course of the local inflammatory process. During the study, 4 groups of dogs were formed, in which the volume of the affected tissue, the degree of inflammation, pain syndrome and the growth rate of unresectable malignant neoplasms in dogs were determined. “Firocoxib” was used in three groups as a nonsteroidal anti-inflammatory drug in combination with “Carboplatin” (an alkylating antineoplastic drug), the fourth group served as a control (“Carboplatin” was used in monotherapy for animals in this group).</p><p>According to the results of the study, “Firocoxib” reduced the inflammatory component and the degree of pain in the area of localization of the oncological process, which significantly improved the quality of life in all three groups of dogs compared with the control, while no side effects were detected. “Firocoxib” has been shown to significantly enhance the antitumor activity of “Carboplatin” by relieving the inflammatory process and partially inhibiting tumor development, leading to partial remission and increased overall survival.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ингибитор циклооксигеназы-2</kwd><kwd>«фирококсиб»</kwd><kwd>злокачественные новообразования</kwd><kwd>апоптоз</kwd><kwd>неоплазия</kwd><kwd>воспаление</kwd><kwd>собаки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>сyclooxygenase-2 inhibitor</kwd><kwd>“Firocoxib”</kwd><kwd>malignant neoplasms</kwd><kwd>apoptosis</kwd><kwd>neoplasia</kwd><kwd>inflammation</kwd><kwd>dogs</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">Лозовская Е.А., Силкин И.И.
