Additional Information
- The Gastric HER2 program fulfills the proficiency testing requirement stated in the CAP/ASCP/ASCO Gastroesophageal HER2 Testing Guideline.
- The interpretive criteria for HER2 immunohistochemistry performed on gastroesophageal adenocarcinomas differs significantly from breast carcinoma. The GHER2 program will help participating laboratories understand these differences.
- The Gastric HER2 program also fulfills the proficiency testing requirement for new "Pan-Tumor HER2" treatment indications, since the assay-scoring system combination is the same for both Pan-Tumor and Gastric HER2.
