Дизайн исследования – мультицентровое ретроспективное исследование. В исследование были включены 246 пациентов с папиллярным раком щитовидной железы, разделенных на две возрастные группы: подростки и молодые взрослые (15 – 39 лет) и пациенты старше 39 лет.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. У подростков и молодых взрослых отмечались большой размер первичной опухоли, более высокая частота метастазов в лимфатические узлы (43,8 против 23,4%; p=0,007) и рецидивов (8,9 против 2,0%; p=0,035). Мутация BRAF V600E встречалась реже у подростков и молодых взрослых (52,6 против 76,1%; p=0,001). В группе подростков и молодых взрослых рецидив был ассоциирован с метастазами в лимфатические узлы, более высокой категорией T, мутацией TERT-p и сочетанием BRAF V600E/TERT-p.</p></sec><sec><title>Выводы</title><p>Выводы. Результаты свидетельствуют, что у подростков и молодых взрослых папиллярный рак щитовидной железы характеризуется более агрессивным локорегионарным течением, что обосновывает необходимость комплексной клинико-молекулярной оценки риска рецидива.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim.

The study design was a multicentre retrospective study.

The BRAF V600E mutation was less common in adolescents and young adults (52.6% versus 76.1%; p=0.001). In the group of adolescents and young adults, recurrence was associated with lymph node metastases, a higher T stage, the TERT-p mutation, and the BRAF V600E/TERT-p combination.</p></sec><sec><title>Conclusions</title><p>Conclusions.
