Zusammenfassung

Für die HER2-gerichtete Therapie ist der Nachweis einer Rezeptor-Überexpression und/oder der Genamplifikation mittels In-situ-Hybridisierung (ISH) von entscheidender Bedeutung. Im Laufe von mehr als 15 Jahren haben die Amerikanische Krebsgesellschaft (ASCO) und die Kanadisch-Amerikanische Pathologengesellschaft (CAP) mehrere Empfehlungen zur optimalen HER2-Testung verfasst. Für das Mammakarzinom wurde zuletzt 2018 eine Aktualisierung herausgegeben, wobei für die Interpretation von ISH-Befunden spezielle diagnostische Gruppen (1-5) definiert wurden. Die vor allem auf der ToGA-Studie basierende Empfehlung für das Magenkarzinom (2017) wird häufig auch als Leitlinie für die Testung anderer gastrointestinaler Tumoren, einschließlich Pankreas und Gallenwege, und das Bronchialkarzinom verwendet. Als Entscheidungsgrundlage für HER2-gerichtete Therapien dient neuerdings als dritte Form der HER2-Genalteration (neben Überexpression und Amplifikation) auch der Mutationsnachweis. Dieser erfolgt mit Hilfe des Next Generation Sequencing (NGS) und eröffnet im Falle einer aktivierenden HER2-Mutation neue Therapieoptionen.

Abstract

A prerequisite for all HER2 directed therapies is the demonstration of HER2 receptor protein overexpression and/or gene amplification by in situ hybridization (ISH). ASCO and CAP have published several HER2 test guidelines over the past 15 years for both breast and gastric cancer. The latest version for breast cancer (2018) focuses on special issues of ISH related to the definitions of special diagnostic groups (1–5). The guidelines for gastroesophageal adenocarcinoma (2017), essentially based on ToGA trial data, are now also being used for other tumors such as pancreas, gallbladder, and non-small-cell lung cancer. For colorectal cancer, a modified testing procedure has been proposed. Recently, besides overexpression and amplification, a third type of HER gene alteration, namely mutation, has gained much interest. Next-generation sequencing (NGS) allows detection of both amplification and mutation of the HER2 gene providing new options of therapy especially in the case of activating mutations.
