Фиброламеллярная гепатоцеллюлярная карцинома (ФлК) развивается чаще всего у молодого населения. В ФлК отмечается вариабельная гистоархитектоника, возможно наличие склерозирующего компонента, очагов некроза и дистрофии опухолевых клеток.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Оценить влияние доли склерозирующего компонента в ФлК печени на течение и прогноз заболевания. Определить взаимосвязь доли склерозирующего компонента в опухоли и частоты микрососудистой инвазии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ретроспективное исследование включено 34 больных с диагнозом «ФлК», которым на первом этапе выполнялось радикальное хирургическое лечение. Произведена гистологическая оценка доли (%) склерозирующего компонента в ФлК. Было оценено влияние доли склерозирующего компонента на общую (ОВ) и безрецидивную (БРВ) выживаемость. Проведен анализ взаимосвязи доли склерозирующего компонента в опухоли и частоты микрососудистой инвазии.</p></sec><sec><title>Результаты</title><p>Результаты. Достоверно худшая БРВ достигнута в группах больных со склерозирующим компонентом в ФлК &gt; 5%, чем в группе больных со склерозирующим компонентом в ФлК ≤ 5% (p = 0,0010; p = 0,024; log-rank test). Медиана БРВ в 1-й группе – 107 (95% ДИ, 22–192) мес.; во 2-й – 11 (95% ДИ, 8–14) мес.; в 3-й – 21 (95% ДИ, 8–33). Частота гистологически подтвержденной микрососудистой инвазии в сравниваемых группах была 29, 74, 87,5% соответственно. ОВ достоверно хуже в двух группах (27 больных суммарно) со склерозирующим компонентом в ФлК &gt; 5%, чем в группе больных со склерозирующим компонентом в ФлК ≤ 5%. Медиана ОВ в 1-й группе – 120 (95% ДИ, 60–180) мес.; во 2-й – 41 (95% ДИ, 15–92) мес.; в 3-й – 69 (95% ДИ, 35–103). Выявлена прямая зависимость между увеличением доли склерозирующего компонента в опухоли и увеличением частоты микрососудистой инвазии.</p></sec><sec><title>Выводы</title><p>Выводы. Можно предположить, что выраженность склерозирующего компонента в опухоли ФлК может служить эффективным морфологическим маркером менее благоприятного прогноза при данном подтипе ГЦР и коррелировать с частотой микрососудистой инвазии. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Fibrolamellar hepatocellular carcinoma (FLC), which develops most often in the younger population. In FLC, variable histoarchitectonics are noted, possibly the presence of a sclerosing component, foci of necrosis and dystrophy of tumor cells.</p></sec><sec><title>Objective</title><p>Objective. Assessment of the influence of the proportion of the sclerosing component in fibrolamellar carcinoma (FLC) of the liver on the course and prognosis of the disease. Determination of the relationship between the proportion of the sclerosing component in the tumor and the frequency of microvascular invasion.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective study included 34 patients with a diagnosis of FLC, who underwent radical surgical treatment at the first stage. A histological assessment of the proportion (%) of the sclerosing component in FLC was made. The effect of  the  proportion of  the  sclerosing component on overall (OS) and relapse-free (DFS) survival was assessed. The  analysis of the relationship between the proportion of the sclerosing component in the tumor and the frequency of microvascular invasion was carried out.</p></sec><sec><title>Results</title><p>Results. Significantly worse RFS was achieved in the groups of patients with a sclerosing component in FLC &gt; 5% than in the group of patients with a sclerosing component in FLC ≤ 5% (p = 0.0010; p = 0.024; log – rank test). Median DDS in group 1 is 107 (95% CI, 22–192) months; at 2 – 11 (95% CI, 8–14) months; in 3 – 21 (95% CI, 8–33). The frequency of histologically confirmed microvascular invasion in the compared groups was 29, 74, 87.5%, respectively. OS was significantly worse in 2 groups (27 patients in total) with a sclerosing component in FLC &gt; 5% than in the group of patients with a sclerosing component in FLC ≤ 5%. Median OS in group 1 120 (95% CI, 60–180) months; at 2 – 41 (95% CI, 15–92) months; in 3 – 69 (95% CI, 35–103). A direct relationship was found between an increase in the proportion of the sclerosing component in a tumor and an increase in the frequency of microvascular invasion.</p></sec><sec><title>Conclusions</title><p>Conclusions. We can assume that the severity of the sclerosing component in the FLK tumor can serve as an effective morphological marker of a less favorable prognosis for this HCC subtype and correlate with the frequency of microvascular invasion. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>фиброламеллярная карцинома</kwd><kwd>опухоль печени</kwd><kwd>прогноз</kwd><kwd>склерозирующий компонент</kwd><kwd>микрососудистая инвазия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fibrolamellar carcinoma</kwd><kwd>liver tumor</kwd><kwd>prognosis</kwd><kwd>sclerosing component</kwd><kwd>microvascular invasion</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">Craig J.R., Peters R.L., Edmondson H.A., Omata M.
