Проведено молекулярно-генетическое исследование образцов опухолевой ткани 33 больных с внутрипеченочным холангиоцеллюлярным раком, полученных после хирургического лечения с помощью полимеразной цепной реакции в реальном времени.</p></sec><sec><title>Результаты</title><p>Результаты. В российской популяции частота мутации гена KRAS при ВПХЦР составила 27%, преимущественно в 12 (78%), 13 (33%), 61 (55%), 117 (44%), 146 (44%) кодонах 2, 3, 4-го экзонов. В отношении KRAS-мутации внутрипеченочный холангиоцеллюлярный рак отличается выраженной гетерогенностью: как правило, имеет место множественная мутация гена KRAS в нескольких локусах и комутация в других генах, в частности, в генах IDH1/IDH2, PIK3CA, NRAS, BRAF. Мутация гена KRAS при ВПХЦР встречается у женщин достоверно чаще. Общая выживаемость была достоверно выше у пациентов с KRAS-мутацией по сравнению с диким типом гена. В отношении безрецидивной выживаемости в группах пациентов с мутантным и диким типом гена KRAS достоверной разницы выявлено не было.</p></sec><sec><title>Заключение</title><p>Заключение. В российской популяции негативной ассоциации между мутацией в гене KRAS и клиническими исходами выявлено не было.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the effect of mutations in the KRAS gene on the clinical course of intrahepatic cholangiocellular cancer (ICC) after surgical treatment in the Russian population.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A molecular genetic study of tumour tissue samples from 33 patients with intrahepatic cholangiocellular cancer obtained after surgical treatment was carried out using real-time polymerase chain reaction.</p></sec><sec><title>Results</title><p>Results. In the Russian population, the frequency of mutations in the KRAS gene in ICC was 27%, mainly in 12 (78%), 13 (33%), 61 (55%), 117 (44%) and 146 (44%) codons of 2, 3, 4 exons. In terms of KRAS gene mutations, intrahepatic cholangiocellular cancer is characterised by a pronounced heterogeneity. As a rule, the KRAS gene demonstrates multiple mutations at several loci and co-mutations in other genes, in particular, in IDH1/IDH2, PIK3CA, NRAS and BRAF genes. KRAS gene mutations in ICC were found to be significantly more common in women. The overall survival rate was significantly higher in patients with a KRAS mutation as compared to those with the wild type of the gene. Regarding the relapse-free survival rate in the groups of patients with the mutant and wild type of the KRAS gene, no significant differences were found.</p></sec><sec><title>Conclusion</title><p>Conclusion. In the Russian population, no negative association between mutations in the KRAS gene and clinical outcomes was observed.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>мутация гена KRAS</kwd><kwd>внутрипеченочный холангиоцеллюлярный рак</kwd><kwd>хирургическое лечение</kwd><kwd>клиническое течение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>KRAS gene mutation</kwd><kwd>intrahepatic cholangiocarcinoma</kwd><kwd>surgical treatment</kwd><kwd>clinical course</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">Pellino A., Loupakis F., Cadamuro M., Dadduzio V., Fassan M., Guido M., et al.
