HER2-тестирование методами иммуногистохимии, флуоресцентной (FISH) и хромогенной (SISH) in situ гибридизации при раке желудка и пищеводно-желудочного перехода
Статья посвящена анализу различных методов определения HER2-статуса распространенного рака желудка. На собственном материале проведено сравнение различных антител, использующихся при тестировании, и различных вариантов выявления амплификации гена HER2. Даны рекомендации по использованию предлагаемых методов.
Ключевые слова: HER2, рак желудка, иммуногистохимия, in situ гибридизация.
________________________________________________
Recent evidence suggests that trastuzumab, a monoclonal antibody which targets HER2, in combination with chemotherapy is a therapeutic option in patients with HER2-positive gastric or gastroesophageal junction cancer. In this connection determine of HER2-overexpression/amplification is crucial aspect for adequate treatment such patients. The article presents our own results of the comparison of different antibodies used for HER2 testing and analysis of different options to identify gene amplification HER2 with practical recommendations.
