В качестве материала для исследования были использованы образцы ДНК, выделенные из опухолевой ткани, полученной из срезов парафиновых блоков. Экстракция ДНК производилась с помощью набора «GeneRead DNA FFPE Kit (50)» (Qiagen). Молекулярно-генетическое исследование проводилось методом высокопроизводительного секвенирования (NGS) с использованием коммерческой панели для целевого обогащения генов GeneReader Actionable Insights Tumor Panel (GRTP – 101X) на платформе QCI Analyser version 1.1 (Qiagen), позволяющей анализировать 12 генов, вовлеченных в канцерогенез: KRAS, NRAS, KIT, BRAF, PDGFRA, ALK, EGFR, ERBB2, PIK3CA, ERBB3, ESR1, RAF1.</p></sec><sec><title>Результаты</title><p>Результаты. Таргетное секвенирование забрюшинных неорганных миксоидных липосарком продемонстрировало генетическую гетерогенность. Нами впервые выявлены мутации и полиморфные варианты в генах EGFR, PIK3CA, ALK, BRAF,ERBB2/3, ESR1, KIT, PDGFRA.</p></sec><sec><title>Заключение</title><p>Заключение. Данное исследование демонстрирует широкий спектр молекулярногенетических перестроек при забрюшинных неорганных миксоидных липосаркомах. Синонимичные мутации в генах EGFR (Q787Q) и PDGFRA (P567P) выявлены во всех случаях (100 %), миссенс-мутация в гене ERBB2 (P1170A) и синонимичные мутации в генах ALK (G845G) и BRAF (G643G) – в 75 %, а миссенс-мутация в гене PIK3CA (I391M) обнаружена в 25 % случаев. Представленные в работе полиморфизмы генов, вероятнее всего, вовлечены в канцерогенез ретроперитонеальных миксоидных липосарком. Необходимы дальнейшие исследования с включением большего количества пациентов и многофакторным анализом отдаленных результатов лечения. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to detect new molecular genetic markers and therapeutic targets in retroperitoneal myxoid liposarcoma.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. DNA samples isolated from tumor tissue and obtained from formalinfixed paraffin-embedded (FFPE) slides were used. DNA was extracted using the GeneRead DNA FFPE Kit (50) (Qiagen). High-throughput next generation sequencing (NGS) using the GeneReader Actionable Insights Tumor Panel (GRTP – 101X) on the QCI Analyzer version 1.1 platform (Qiagen) was used for molecular genetic analysis of 12 genes involved in carcinogenesis: KRAS, NRAS, KIT, BRAF, PDGFRA, ALK, EGFR, ERBB2, PIK3CA, ERBB3, ESR1, RAF1.</p></sec><sec><title>Results</title><p>Results. Targeted sequencing of retroperitoneal extra-organ myxoid liposarcoma demonstrated genetic heterogeneity. Our study was the first to describe mutations and polymorphic variants in genes, such as EGFR, PIK3CA, ALK, BRAF, ERBB2 / 3, ESR1, KIT, PDGFRA in myxoid liposarcoma.</p></sec><sec><title>Conclusion</title><p>Conclusion. This study demonstrated a wide range of molecular genetic rearrangements in retroperitoneal extra-organ myxoid liposarcoma. Synonymous mutations in the EGFR (Q787Q) and PDGFRA (P567P) genes were detected in all cases (100 %). Missense mutations in the ERBB2 gene (P1170A) and synonymous mutations in the ALK (G845G) and BRAF genes were identified in 75 % of cases. Missense mutation in the PIK3CA gene (I391M) was detected in 25 % of cases. The gene polymorphisms presented in this paper are most likely involved in the carcinogenesis of retroperitoneal myxoid liposarcoma. Further studies with larger patient groups and multivariate analysis of long-term treatment results are required. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>липосаркома</kwd><kwd>миксоидные липосаркомы</kwd><kwd>неорганные забрюшинные опухоли</kwd><kwd>высокопроизводительное секвенирование (NGS)</kwd><kwd>полиморфизм</kwd><kwd>мутации</kwd><kwd>EGFR</kwd><kwd>PDGFRA</kwd><kwd>ERBB2</kwd><kwd>BRAF</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liposarcoma</kwd><kwd>myxoid liposarcoma</kwd><kwd>extra-organ retroperitoneal tumor</kwd><kwd>next-generation sequencing (NGS)</kwd><kwd>polymorphism</kwd><kwd>mutation</kwd><kwd>EGFR</kwd><kwd>PDGFRA</kwd><kwd>ERBB2</kwd><kwd>BRAF</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">Каприн А.Д., Старинский В.В., Петрова Г.В.
