The incidence of head and neck cancer in Russia is 4.12 per 100,000. Despite all the achievements of current oncology, approximately 50–60 % of patients with locally advanced head and neck cancer develop relapses within the first 2 years after treatment completion.</p><p><bold>The study objective </bold>is to analyze the effectiveness of regional intra-arterial polychemotherapy in the combined and comprehensive treatment of locally advanced oral cancer.</p><p><bold>Materials and methods.</bold> This prospective study included 29 patients with oral squamous cell carcinoma treated and followed-up at N.N. Blokhin National Cancer Research Center between 2017 and 2020. The majority of patients (82.8 %) had stage III–IV disease. We evaluated clinical response to neoadjuvant regional intra-arterial chemotherapy, pathomorphosis of the primary tumor after surgery, treatment toxicity, overall survival, and relapse-free survival.</p><p><bold>Results.</bold> The objective response rate assessed for the primary oral tumor after regional intra-arterial chemotherapy was 100 %; complete regression of the primary tumor was achieved in 82.8 % of patients. More than one-third of participants (35.5 %) had complete regression of metastases in regional lymph nodes. In 73.5 % of patients who had under gone neoadjuvant regional intra-arterial chemotherapy followed by surgery, we observed grade IV therapeutic pathomorphosis of the primary tumor. The 2-year relapse-free survival rate was 100 % in individuals with stage II–III disease and 92.9 ± 6.9 % in patients with stage IV disease.</p><p><bold>Conclusion.</bold> The administration of regional intra-arterial chemotherapy as an induction stage ensures high treatment efficacy and high rate of complete pathomorphological responses. This suggests the opportunity of conservative treatment for patients with locally advanced oral cancer, which is currently considered impossible for such patients. Moreover, this method demonstrated moderate systemic toxicity, which expands the indications for its use and increase treatment compliance.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Рак органов головы и шеи является актуальной медико-социальной проблемой. Ежегодно в мире диагностируется 377 713 новых случаев данного заболевания и 177 757 летальных исходов, связанных с ним. Стандартизованный показатель заболеваемости в России находится на уровне 4,12 случая на 100 тыс. населения. Несмотря на все достижения современной онкологической практики, у 50–60 % пациентов с местно-распространенными формами рака органов головы и шеи развивается рецидив в первые 2 года после окончания лечения.</p><p><bold>Цель исследования </bold>– изучение эффективности регионарной внутриартериальной полихимиотерапии в комбинированном и комплексном лечении рака слизистой оболочки полости рта.</p><p><bold>Материалы и методы.</bold> В проспективное исследование включены 29 пациентов с плоскоклеточным раком слизистой оболочки полости рта, наблюдавшихся и получавших лечение в Национальном медицинском исследовательском центре онкологии им. Н.Н. Блохина с 2017 по 2020 г. У 82,8 % больных было заболевание III–IV стадии. Оценивался клинический ответ опухоли на неоадъювантную регионарную внутриартериальную химиотерапию, а также патоморфоз в опухолевом очаге после хирургического вмешательства, токсичность лечения и показатели общей и безрецидивной выживаемости.</p><p><bold>Результаты. </bold>Частота объективного ответа в отношении первичного опухолевого очага полости рта после регионарной внутриартериальной химиотерапии составила 100 %, частота полной регрессии опухолевого очага – 82,8 %. В отношении метастазов в регионарных лимфатических узлах полная регрессия выявлена у 35,5 % пациентов. У 73,5 % больных, которым выполнено хирургическое вмешательство, после неоадъювантной регионарной внутриартериальной химиотерапии в опухолевом очаге зарегистрирован патоморфоз IV степени. Показатель 2летнейбезрецидивной выживаемости пациентов с заболеванием II–III стадии был на уровне 100 %, с заболеванием IV стадии – 92,9 ± 6,9 %.</p><p><bold>Заключение. </bold>Применение регионарной внутриартериальной химиотерапии в качестве индукционного этапа демонстрирует высокую эффективность и высокий уровень полных патоморфологических ответов. Это позволяет сделать предположение о возможности проведения консервативного лечения местно-распространенных форм рака слизистой оболочки полости рта, что на сегодняшний день является недостижимой опцией в терапии данной группы больных. Также немаловажно, что весьма умеренный спектр системной токсичности позволяет расширить показания к применению данной методики и повысить комплаентность к лечению.</p></trans-abstract><kwd-group xml:lang="en"><kwd>intra-arterial chemotherapy</kwd><kwd>cancer of the oral mucosa</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>внутриартериальная химиотерапия</kwd><kwd>рак слизистой оболочки полости рта</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Warnakulasuriya S.
