There is no information about the choice of classification for fibrolamellar liver carcinoma (FLC) in the world literature, and data on the prognostic significance of clinical aspects in FLC are very contradictory and require further study.</p> <p><bold><italic>AIM:</italic></bold> To evaluate the practical significance of staging systems for operable hepatocellular cancer for fibrolamellar carcinoma (TNM/AJCC, BCLC) as a separate option, to study the influence of clinical aspects (disease stage, gender, age, size of tumor) of patients with FlC on the long-term results of their treatment.</p> <p><bold><italic>MATERIALS AND METHODS:</italic></bold> The retrospective study included 34 patients with FlC who underwent radical surgical treatment at the first stage at the Blokhin National Research Institute of Oncology of the Ministry of Health of the Russian Federation from 2005 to 2020.</p> <p><bold><italic>RESULTS:</italic></bold> When assessing the prevalence of the disease according to the TNM-8/AJCC system, a significant correlation between the FlC stage and the prognosis was revealed. It is proved that the greatest RFS was achieved in the group of stages II–IIIB, while the smallest RFS was achieved in the group with stage IVB (<italic>p</italic>=0.002; <italic>p</italic>=0.000). The highest OS was achieved in the group of stages II–IIIB, while the lowest OS was achieved in the group with stage IVB (<italic>p</italic>=0.050; <italic>p</italic>=0.000). The OV of patients with FlC was not dependent</p> <p><bold><italic>CONCLUSIONS:</italic></bold> The TNM-8/AJCC classification optimally predicts the results of surgical treatment of FlC. The use of the Barcelona staging system for this subtype of liver cancer is impractical. The size of the primary tumor, as part of the FlC staging system, turned out to be an independent prognostic factor. The age of the patient ≥20 years correlates with the deterioration of OV.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Обоснование.</italic></bold> Фиброламеллярная карцинома печени (ФлК) представляет собой редкий подтип рака печени с неизученной этиологией. Информация о выборе классификации для ФлК в мировой литературе отсутствует, а данные о прогностической значимости клинических аспектов при ФлК весьма противоречивы и требуют дальнейшего изучения.</p> <p><bold><italic>Цель.</italic></bold> Оценить практическую значимость систем стадирования операбельного гепатоцеллюлярного рака для ФлК (TNM/AJCC, BCLC) как отдельного варианта, изучить влияние клинических аспектов (стадия заболевания, пол, возраст, размер опухоли) пациентов с ФлК на отдалённые результаты их лечения.</p> <p><bold><italic>Материалы и методы.</italic></bold> В ретроспективное исследование включено 34 больных с ФлК, которым на первом этапе выполнялось радикальное хирургическое лечение в ФГБУ «НМИЦ онкологии им. Н.Н. Блохина» Министерства здравоохранения Российской Федерации с 2005 по 2020 г.</p> <p><bold><italic>Результаты.</italic></bold> При оценке распространённости заболевания по системе TNM-8/AJCC выявлена значимая корреляция стадии ФлК и прогнозом. Доказано, что наибольшая безрецидивная выживаемость (БРВ) достигнута в группе II–IIIB стадий, в то время как самая наименьшая БРВ в группе с IVB стадией (<italic>p</italic>=0,002; <italic>p</italic>=0,000). Наибольшая общая выживаемость (ОВ) достигнута в группе II–IIIB стадий, в то время как наименьшая ОВ – в группе с IVB стадией (<italic>p</italic>=0,050; <italic>p</italic>=0,000). ОВ пациентов с ФлК не зависела от пола (<italic>p</italic>=0,679). Барселонская система стадирования рака печени полноценно не отразила влияние на прогноз заболевания, оценить распространённость онкологического процесса при ФлК невозможно. Доказана связь размера первичной опухоли с прогнозом заболевания. Наибольшая ОВ достигнута в группе ФлК ≤10 см, в то время как самая короткая ОВ в группе ФлК &gt;10см (<italic>p</italic>=0,054). ОВ достоверно выше в группе больных ФлК &lt;20 лет, чем в группах 20 лет включительно и старше (<italic>p</italic>=0,011; <italic>p</italic>=0,042).</p> <p><bold><italic>Заключение.</italic></bold> Классификация TNM-8/AJCC оптимально прогнозирует результаты хирургического лечения ФлК. Применение Барселонской системы стадирования при данном подтипе рака печени нецелесообразно. Размер первичной опухоли как часть системы стадирования ФлК оказался независимым фактором прогноза. Возраст пациента ≥20 лет коррелирует с ухудшением ОВ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>fibrolamellar carcinoma</kwd><kwd>liver tumor</kwd><kwd>forecast</kwd><kwd>TNM classification</kwd><kwd>BCLC</kwd><kwd>floor</kwd><kwd>age</kwd><kwd>tumor size</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>фиброламеллярная карцинома</kwd><kwd>опухоль печени</kwd><kwd>прогноз</kwd><kwd>TNM классификация</kwd><kwd>BCLC</kwd><kwd>пол</kwd><kwd>возраст</kwd><kwd>размер опухоли</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Edmondson HA.
