Адренокортикальный рак (АКР) является орфанным заболеванием с неблагоприятным прогнозом. Наиболее эффективная терапевтическая опция в лечении метастатического АКР — это назначение комбинации химиотерапии по схеме EDP и митотана. Однако публикаций по сравнению эффективности терапии по схеме EDP в комбинации с митотаном и без него нет.</p></sec><sec><title>Цель</title><p>Цель. Сравнение эффективности химиотерапии по схеме EDP с митотаном и без него в терапии метастатического АКР, а также изучение предиктивных и прогностических факторов эффективности терапии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Ретроспективный анализ историй болезни пациентов с гистологически подтвержденным метастатическим АКР, получивших хотя бы один курс химиотерапии по схеме EDP±митотан. В исследование включено 73 пациента, из которых 49 получили комбинацию EDP и митотана и 24 — химиотерапию по схеме EDP.</p></sec><sec><title>Результаты</title><p>Результаты. Частота объективных ответов составила 18,4% в группе EDP+митотан против 4,1% в группе EDP. Контроль заболевания наблюдался в 25 (51%) и 13 (54,2%) случаев, соответственно. Достоверных различий в выживаемости без прогрессирования (ВБП) между группами EDP и EDP+митотан не получено, медиана ВБП составила 6,5 и 6,0 месяца, соответственно. Медиана общей выживаемости (ОВ) в общей популяции составила 20,9 месяцев, достоверных различий между группами не получено. Однако у больных, достигших терапевтической концентрации митотана, отмечалось увеличение медианы ВБП. При этом достижение терапевтической концентрации митотана было единственным фактором, достоверно ассоциированным с улучшением ВБП (отношение рисков [HR] 0,44, р =0,006). Достоверными фактором неблагоприятного прогноза, ассоциированными с ухудшением ОВ, стали уровень Ki-67 в первичной опухоли &gt;20% (HR 10,5, р =0,006) и наличие более 1 зоны метастазирования (HR 3,82, р =0,02).</p></sec><sec><title>Заключение</title><p>Заключение. В данном исследовании показано, что добавление митотана к химиотерапии по схеме EDP не улучшает медиану ВБП и ОВ во всей популяции больных, но достижение терапевтической концентрации митотана достоверно связано с улучшением ВБП.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Adrenocortical carcinoma (ACC) is an orphan disease with an unfavorable prognosis. The most effective therapeutic option in the treatment of ACC is EDP plus mitotane combination chemotherapy. However, no studies comparing the efficacy of the EDP regimen with or without mitotane have been published.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective analysis of health records of patients with histologically confirmed metastatic ACC, who received at least one chemotherapy cycle with EDP ± mitotane. The study included 73 patients, 49 of which received a combination of EDP and mitotane and 24 were treated with EDP chemotherapy.</p></sec><sec><title>Results</title><p>Results. The objective response rate was 18,4 % in the EDP + mitotane group versus 4,1 % in the EDP group. Disease control was reported in 25 (51 %) and 13 (54,2 %) patients, respectively. No significant differences were found in progression-free survival (PFS) rates between the EDP and EDP + mitotane groups; the median PFS rate was 6,5 and 6,0 months, respectively. The median overall survival (OS) in the total population was 20,9 months; no significant differences were found between the groups. However, an increase in median PFS was observed in patients who achieved a therapeutic concentration of mitotane. Moreover, the achievement of therapeutic mitotane concentrations was the only factor significantly associated with improved PFS (HR 0.44, p = 0.006). Significant unfavorable prognostic factors associated with lower OS were Ki-67 level in the primary tumor &gt; 20 % (HR 10.5, p = 0.006) and more than 1 site of metastases (HR 3.82, p = 0.02).</p></sec><sec><title>Conclusions</title><p>Conclusions. This study showed that the addition of mitotane to EDP chemotherapy does not improve the median PFS and OS in the total patient population, however, the achievement of therapeutic mitotane concentrations is significantly associated with improved progression-free survival.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>адренокортикальный рак</kwd><kwd>химиотерапия</kwd><kwd>митотан</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adrenocortical carcinoma</kwd><kwd>chemotherapy</kwd><kwd>mitotane</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">Kerkhofs TM, Verhoeven RH, Van der Zwan JM, et al.
