Dual in situ hybridization (DISH), an alternative to fluorescence in situ hybridization (FISH) and immunohistochemistry, is now available. To compare the FISH and DISH methods, we tested 251 samples enriched for common or difficult-to-assess HER2 anomalies. The interpretation for HER2 FISH testing (HER2/CEP17 ratio and gene copy number) is given below: Positive HER2 amplification: FISH ratio is greater than 2.2 or HER2 gene copy is greater than 6.0. The present data suggest that it could be advisable to perform the FISH test in IHC 1+ breast cancers, in order to identify HER2-positive cases that could be misclassified as HER2-negative, thus denying those patients the opportunity of benefitting from HER2-targeted therapy. What do the test results mean?

Changes in genes can make the cancer cell: produce particular proteins Breast tissue results of FISH group 2, 3, or 4 will be reflexed to ERBB2 (HER2/neu) (HercepTest) with Interpretation by Immunohistochemistry, Tissue (ARUP test code 0049174). Additional charges apply.

ASCO and the College of American Pathologists (ASCO-CAP) recently recommended further changes to the evaluation of human epidermal growth factor receptor 2 gene (HER2) amplification by fluorescent in situ hybridization (FISH). With a FISH test, special labels with chemicals added to them change color and glow in the dark when they attach to HER2 proteins. It looks for extra copies of the HER2 gene. The FISH test is the Testing for HER2 Testing for HER2 may be done by means of either immunohistochemistry (IHC) or fluorescence in situ hybridization (FISH).
