- GI vs. Breast Guidelines: Understanding the critical differences in interpreting HER2 Immunohistochemistry (IHC) results, including scoring criteria, membrane staining requirements, and tissue sampling specifics (e.g., cohesive cell clusters in biopsies).
- Testing Rationale and Methods: Why first-line HER2 testing is now standard for BTC and GEA, and the advantages of usin ...
