Оценить выживаемость пациентов с локализованным раком полости рта (cT1 2N0M0) в зависимости от тактики лечения регионарных зон метастазирования по данным ракового регистра Архангельской области и Ненецкого автономного округа (ПРР АО и НАО) в 2010–2024 гг.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы. Проведено популяционное ретроспективное когортное исследование с включением 204 пациентов из базы данных ракового регистра Архангельской области и Ненецкого автономного округа. В зависимости от тактики лечения все больные были разделены на четыре группы: 1) радикальная хирургическая операция на первичном очаге в сочетании с профилактической шейной лимфодиссекцией (n = 63); 2) радикальная хирургическая операция на первичном очаге с шейной лимфодиссекцией и последующей адъювантной лучевой/ химиолучевой терапией (n = 38); 3) лучевая/химиолучевая терапия в качестве самостоятельного метода (n = 69); 4) только радикальное удаление первичной опухоли без воздействия на регионарные зоны (n = 34). Конечной точкой исследования являлась опухолеспецифическая выживаемость. Для анализа применялись метод Каплана – Мейера, лог-ранговый критерий и регрессионная модель Кокса.</p></sec><sec><title>Результаты</title><p>Результаты. 5‑летняя опухолеспецифическая выживаемость в общей когорте составила 70,8 % (95 % ДИ: 63,2–77,1 %). После коррекции на стадию, возраст, пол, морфологию, место проживания и временной период группа хирургии с профилактической лимфодиссекцией показала наилучший прогноз. Отказ от воздействия на регионарные зоны увеличивал риск смерти в 2,9 раза (HR = 2,90; 95 % ДИ: 1,01–8,37; p = 0,049), а лучевая терапия как самостоятельный метод – в 3,24 раза (HR = 3,24; 95 % ДИ: 1,42–7,38; p = 0,005). Риск в группе с адъювантной лучевой терапией статистически не отличался от референтного (HR = 1,63; p = 0,276). II стадия (HR = 2,72; p = 0,013) и возраст 50–69 лет (HR = 1,99; p = 0,023) являлись независимыми неблагоприятными прогностическими факторами.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты популяционного исследования демонстрируют, что радикальное хирургическое вмешательство на первичном очаге в сочетании с профилактической шейной лимфодиссекцией является оптимальной тактикой лечения пациентов с локализованным раком полости рта. Отказ от воздействия на регионарные зоны или использование лучевой терапии как самостоятельного метода в реальной клинической практике ассоциированы со статистически значимым повышением риска смерти от заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. To evaluate the impact of different management strategies for regional nodal metastases on survival in patients with localized oral cavity cancer (cT1–2N0M0), based on data from the population-based cancer registry of Arkhangelsk Oblast and Nenets Autonomous Okrug (PCR AO and NAO) over the period 2010–2024.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. A population-based retrospective cohort study was conducted including 204 patients from the Population-Based Cancer Registry of the Arkhangelsk Region and the Nenets Autonomous Okrug. According to the treatment strategy chosen, patients were allocated to four groups: 1) radical surgery of the primary tumor with prophylactic neck lymph node dissection (n = 63); 2) radical surgery of the primary tumor with neck lymph node dissection followed by adjuvant radiation/chemoradiation therapy (n = 38); 3) radiation/chemoradiation therapy as a standalone treatment (n = 69); 4) radical surgery directed to the primary tumor only, without regional lymph node treatment (n = 34). Survival analysis was performed using the Kaplan–Meier method, the log-rank test, and the Cox proportional hazards regression model.</p></sec><sec><title>Results</title><p>Results. The 5‑year cancer-specific survival rate in the overall cohort was 70.8 % (95 % CI, 63.2–77.1 %). After adjustment for stage, age, sex, morphology, place of residence, and calendar period, the surgery group with elective neck dissection demonstrated the most favorable prognosis. Compared with this reference group, omission of regional lymph node treatment was associated with a 2.9‑fold increase in the risk of death (HR = 2.90; 95 % CI, 1.01–8.37; p = 0.049), while definitive radiotherapy as a standalone modality was associated with a 3.24‑fold increase (HR = 3.24; 95 % CI, 1.42–7.38; p = 0.005). The risk in the adjuvant radiotherapy group did not differ significantly from that in the reference group (HR = 1.63; p = 0.276). Stage II disease (HR = 2.72; p = 0.013) and age 50–69 years (HR = 1.99; p = 0.023) were independent adverse prognostic factors.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of this population based study demonstrate that radical surgery of the primary tumor combined with prophylactic neck lymph node dissection is the optimal treatment strategy for patients with Stage I–II oral cavity cancer. Omission of regional lymph node treatment or the use of radiation therapy as a standalone method in routine clinical practice are associated with a statistically significant increase in the risk of disease specific mortality.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак полости рта I–II стадии</kwd><kwd>профилактическая лимфодиссекция</kwd><kwd>радиотерапия</kwd><kwd>выживаемость</kwd><kwd>популяционное исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stage I-II oral cavity cancer</kwd><kwd>prophylactic lymph node dissection</kwd><kwd>radiotherapy</kwd><kwd>survival</kwd><kwd>population based study</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">Bray F, Ferlay J, Soerjomataram I, Siegel RL, Torre LA, Jemal A.
