WebJul 24, 2003 · We evaluated HER2/neu gene amplification by fluorescence in situ hybridization (FISH) in archival paraffin-embedded breast cancer tissues. Tumors from 63 human invasive breast cancers were categorized into two groups depending on whether the paraffin-embedded tissue blocks had been stored for more or less than 12 months … WebResults for IHC: A score of 0 or +1 means your tumor is HER2 negative. A score of +2 means the results are unclear and FISH testing should be done. A score of +3 means the tumor is HER2 positive. FISH results are positive or negative. If you are having the blood test, HER2/neu is measured in nanograms per milliliter (ng/mL).
