Актуальность. Мутации в гене PIK3CA относятся к наиболее частым генетическим повреждениям при эстроген-рецептор-(ER)-позитивном раке молочной железы (РМЖ). Детекция мутаций PIK3CA приобрела особую значимость после недавнего внедрения в практику ингибитора PI3K алпелисиба. Частота и спектр обнаруживаемых соматических дефектов PIK3CA зависят от особенностей включенных в анализ случаев, в том числе распределения гистологических и экспрессионных вариантов опухолей, возрастного и даже этнического состава изучаемой группы. Цель. Характеристика частоты и спектра мутаций PIK3CA у российских пациенток с РМЖ. Материалы и методы. Присутствие мутаций в 7, 9 и 20-м экзонах гена PIK3CA определено в выборке из 206 случаев распространенного ER+/HER2- РМЖ. Для поиска мутаций использовалась комбинация плавления ПЦР-продуктов с высоким разрешением, аллель-специфической полимеразной цепной реакции (ПЦР) и цифровой капельной ПЦР. Результаты. Мутации в гене PIK3CA детектированы в 62/206 (30%) случаев. Примечательно, что абсолютное большинство выявленных повреждений (59/62, 95%) представлено всего тремя частыми разновидностями миссенс-замен: p.E542K, p.E545K и p.H1047R. При анализе клинико-морфологических характеристик обнаружены тенденции к ассоциации мутаций PIK3CA со старшим возрастом и более частым метастатическим поражением легких. Заключение. Информация о частоте и спектре соматических аберраций PIK3CA может быть применена при организации молекулярно-генетического тестирования больных РМЖ и использовании ингибиторов PI3K в нашей популяции.
Background. PIK3CA belongs to the top three most frequently mutated genes in breast cancer (BC), especially in estrogen receptor (ER) positive, HER2 negative BC subtype. With an approval of selective PI3K-alpha inhibitor, alpelisib, this alteration has become actionable in ER+HER2- tumors. The frequency and spectrum of PIK3CA alterations in various cohorts is affected by a number of factors, including the distribution of BC expression subtypes, histological types, patient age, and even ethnicity. Aim. Aim of the current study was to characterize the frequency and spectrum of PIK3CA alterations in Russian BC patients. Materials and methods. The analysis of PIK3CA exon 7, 9 and 20 mutations was performed in a cohort of Russian ER+HER2- BC patients by a combination of high-resolution melting analysis, allele-specific PCR, and digital droplet PCR. Results. PIK3CA lesions were identified in 62/206 (30%) patients. Noteworthy, 59/62 (95%) of the identified variants were represented by the three most common p.E542K, p.E545K, and p.H1047R substitutions. The analysis of clinical and morphological characteristics revealed the trends towards association of PIK3CA mutations with older age and more frequent metastatic lung involvement. Conclusion. The obtained data on the frequency and spectrum of PIK3CA somatic aberrations can be helpful when organizing molecular genetic testing of breast cancer patients and using PI3K inhibitors in Russian population.
