In about 80 % of cases, this pathology is diagnosed at stage III–Iv, which causes an unfavorable prognosis of the disease.</p><p><bold>Aim. </bold>To evaluate effectiveness of an integrated approach to treatment of stage III–Iv squamous cell carcinoma of the nasal cavity and paranasal sinuses.</p><p><bold>Materials and methods.</bold> The study included 126 patients with locally advanced squamous cell carcinoma of the nasal cavity and paranasal sinuses who were treated and observed during 2000–2020 at the N. N. Blokhin National medical Research Center for Oncology. Depending on the choice of treatment tactics at the 1<sup>st</sup> stage, patients were divided into 3 groups. group 1 (<italic>n</italic> = 55) included patients who underwent conservative treatment (radiation or chemoradiation) therapy in an independent version, group 2 (<italic>n</italic> = 31) – patients who underwent surgery with adjuvant radiation therapy, group 3 (<italic>n</italic> = 40) – patients who underwent induction radiation or chemoradiation therapy with subsequent surgery. <bold>Results.</bold> Overall 5-year survival rates did not differ between the 3<italic> </italic>groups <italic>(p </italic>&gt;0.05). At the same time, 5-year progression-free survival in group 2 (surgery + adjuvant radiation or chemoradiation therapy) was significantly higher (50.5 %) as compared with groups 1 (conservative treatment) (17 %; <italic>p =</italic> 0.021) and 3 (induction radiation or chemoradiation therapy + surgery) (25.5 %; <italic>p</italic> = 0.031). The five-year progression-free survival of patients with T3 tumor in group 2 was 59.4 %, which was significantly higher than in groups 1 (17.9 %; <italic>p</italic> = 0.021) and 3 (27.1 %; <italic>p</italic> = 0.031). However, there were no between-group differences in progression-free survival in patients with T4 tumor.</p><p><bold>Conclusion.</bold> Local recurrence is the most common cause of disease progression. Surgery with adjuvant radiation therapy, especially in patients with T3 tumor, improves the prognosis of the disease. At the same time, it is advisable to conduct conservative treatment to patients with T4 tumor.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>плоскоклеточный рак полости носа и придаточных пазух является одним из редких злокачественных новообразований. примерно в 80 % случаев данную патологию диагностируют на III–Iv стадии, что обусловливает неблагоприятный прогноз заболевания.</p><p><bold>Цель исследования </bold>– оценить эффективность комплексного подхода к лечению плоскоклеточного рака полости носа и околоносовых пазух III–Iv стадии.</p><p><bold>Материалы и методы. </bold>В исследование включены 126 пациентов с местно-распространенным плоскоклеточным раком полости носа и околоносовых пазух, получавших лечение и наблюдавшихся в 2000–2020 гг. в Национальном медицинском исследовательском центре онкологии им. Н. Н. блохина. В зависимости от выбора тактики лечения на 1-м этапе больные разделены на 3 группы. В группу 1 (<italic>n</italic> = 55) вошли пациенты, которым проведено консервативное лечение – лучевая или химиолучевая терапия в самостоятельном варианте, в группу 2 (<italic>n</italic> = 31) – пациенты, которым выполнена операция с адъювантной лучевой терапией, в группу 3 (<italic>n</italic> = 40) – пациенты, которым проведена индукционная лучевая или химиолучевая терапия с последующим хирургическим вмешательством.</p><p><bold>Результаты. </bold>показатели<bold> </bold>общей 5-летней выживаемости в 3 группах не различались (<italic>p</italic> &gt;0,05). при этом 5-летняя выживаемость без прогрессирования в группе 2 (операция + адъювантная лучевая или химиолучевая терапия) была значительно выше (50,5 %) по сравнению с группами 1 (консервативное лечение) (17 %; <italic>p</italic> = 0,021) и 3 (индукционная лучевая или химиолучевая терапия + операция) (25,5 %; <italic>p</italic> = 0,031). пятилетняя выживаемость без прогрессирования пациентов с опухолью Т3 в группе 2 составила 59,4 %, что оказалось существенно выше, чем в группах 1 (17,9 %; <italic>p</italic> = 0,021) и 3 (27,1 %; <italic>p</italic> = 0,031). Однако межгрупповых различий в выживаемости без прогрессирования у больных с опухолью Т4 выявлено не было.</p><p><bold>Заключение. </bold>Локальный рецидив является наиболее частой причиной прогрессирования заболевания. хирургическое вмешательство с адъювантной лучевой терапией, особенно у пациентов с опухолью Т3, улучшает прогноз заболевания. В то же время больным с опухолью Т4 целесообразно проводить консервативное лечение.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cancer of nasal cavity and paranasal sinuses</kwd><kwd>squamous cell carcinoma</kwd><kwd>locally advanced process</kwd><kwd>long-term result</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак полости носа и придаточных пазух</kwd><kwd>плоскоклеточный рак</kwd><kwd>местно-распространенный процесс</kwd><kwd>отдаленный результат</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Youlden D.R., Cramb S.M., Peters S. et al.
