HER2 gene copy number is specified, and the HER2/chromosome 17 ratio is reported; a normal HER2/chromosome 17 ratio is equal to or less than 1.7 A high HER2/centromeric probe for chromosome 17 fluorescence in situ hybridization (HER2 FISH) ratio has been found to be a significant predictor of overall clinical response and progression-free survival in patients with metastatic breast cancer treated with NST-T. Term Description. The ratio of HER-2/neu to CEP17 probes by in situ hybridization assays (e.g. FISH) to determine overexpression of HER-2/neu protein in breast cancer.
The nuclei microarray FISH (NMFISH) technology serves as a useful platform for analyzing HER2 gene/chromosome 17 centromere ratio. HER2/neu is the human epidermal growth mere chromosome 17 polysomy without HER2 gene If the HER2/CEP17 ratio remains < 2.0 with ≥ 6.0 HER2 The case was reflexed to FISH [fluorescence ISH] due to “histopathologic discordance” and reported as equivocal. The HER2/D17Z1 (chromosome 17 centromere) FISH ratio was 1.4 (negative) “to be interpreted with caution” due to the average copy number signals per cell of HER2 4.6 and D17Z1 3.2 (equivocal). Receptor tyrosine-protein kinase erbB-2, also known as CD340, proto-oncogene Neu, Erbb2, or ERBB2, is a protein that in humans is encoded by the ERBB2 gene. ERBB is abbreviated from erythroblastic oncogene B, a gene isolated from avian genome. It is also frequently called HER2 or HER2/neu.

2005-06-15 2019-03-01 Herein, the authors define the frequency, immunohistochemical correlates, and other clinicopathological features of breast cancers with HER2/CEP17 ratio of 2 or greater and HER2/neu copy number less than 4 (group A), based on an analysis of an institutional cohort assessed for HER2/neu status by both florescence in situ hybridization and immunohistochemistry and scored using 2013 ASCO/CAP criteria.

ERBB is abbreviated from erythroblastic oncogene B, a gene isolated from avian genome. It is also frequently called HER2 or HER2/neu. HER2 is a member of the human epidermal growth factor receptor family.
In the HER2 gene analysis and chromosome 17 amplification, FISH was performed using 4-μm paraffin sections (12, 23 – 25). FISH conducted with thin tissue sections leads to the underestimation of the true chromosome copy number in various types of cancer (26). 2020-06-06
The probemix covers an approximately 600‐kb large region including the HER2 gene on chromosome 17, and the centromeric region of chromosome 17 (CEN‐17). Using a fluorescence microscope (Zeiss Axio Imager.Z1; Carl Zeiss AG, Feldbach, Switzerland), tumor cells are identified, the number of HER2 and CEN‐17 signals counted to a total of 60 gene signals, and the HER2/CEN‐17 ratio calculated.
The most recent full ASCO-CAP guidelines for HER2 testing by in situ hybridization (ISH) changed the evaluation for HER2 amplification requiring formalized assessment of both average HER2 gene number per tumor cell and ratio of average HER2-to-internal control chromosome 17 centromere (CEP17) for assessment of HER2 status by fluorescence in situ hybridization (FISH). 13,14 This scoring Amongst the 41 cases with HER2 IHC2+ and of FISH group 2 in our cohort, 35 cases had a ≤1.75 average CEP17 copy number/cell by FISH, i.e., hypodisomy, which was ascribed to a loss of the whole chromosome or a partial deletion of chromosome 17 involving the centromere for the FISH result to be increased to a HER2/CEP17 ratio of 2.0 or greater, rather than a “true” HER2 gene amplification HER2/CEN-17 ratio ≥ 2.0). No patients were enrolled whose tumors were not gene amplified but HER2 protein weakly to strongly overexpressing [FISH(-)/IHC 2+], therefore it is unclear if patients whose tumors are not gene amplified but HER2 protein-overexpressing [i.e., FISH(-), IHC 2+ or 3+] will benefit from Herceptin® treatment.
Dual-color dual-hapten in situ hybridization (D-DISH) is a new test for assessment of HER2/neu gene overexpression on light microscopy.Aims: This was a validation study for D-DISH in our laboratory and was conducted to study the concordance between
