2020-10-06 The FISH (fluorescence in situ hybridization) test checks the DNA of your cancer cells for extra copies of the HER2/neu gene. This gene makes proteins called HER2 (human epidermal growth factor 2020-01-21 FISH also may be useful as a confirmatory reflex assay for breast carcinoma cases for which an equivocal score has been identified previously by immunohistochemistry. Interpretation HER2 gene amplification is reported as either amplified, not amplified, or equivocal. The HER2 gene copy number is specified, and the HER2/chromosome 17 ratio is reported. 2020-06-06 This means that the HER2 status needs to be tested with FISH to clarify the result. Triple-negative breast tumors don’t have too much HER2 and also don’t have estrogen or progesterone receptors. They are HER2-, ER-, and PR-negative.

If the IHC result is 2+, the HER2 status of the tumor is not clear and is called "equivocal." This means that the HER2 status needs to be tested with FISH to clarify the result. Triple-negative breast tumors don’t have too much HER2 and also don’t have estrogen or progesterone receptors. They are HER2-, ER-, and PR-negative. 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. A score of 3+ is considered HER2-positive. If the IHC test results are borderline, it’s likely that a FISH test will be done on a sample of the cancer tissue to determine if the cancer is HER2-positive. FISH test (F luorescence I n S itu H ybridization): The FISH test uses special labels that attach to the HER2 proteins.

2013-12-30 · Background The gold standard of HER2 status assessment in breast cancer is still debated. Immunohistochemistry (IHC) and in-situ technology as fluorescent-labeled methodology (FISH) can be influenced by pre-analytical factors, assay-conditions and interpretation of test results. We retrospectively conducted this quality control study and analyzed HER2 test results in breast cancer within the 2016-07-27 · FISH HER2 positivity was based on the HER2/CEP17 ratio (> 2.2) and on the average gene copy numbers. Gene copy numbers of >6 and cluster formation (6 copies by smaller clusters and 12 copies by larger clusters) were also defined as positive status.
