For interactive e-learning please use the HER2 FISH pharmDxM e-learning program designed to supply laboratory technicians, pathologists and scientists with an accurate and fast knowledge of how to achieve optimal results using HER2 FISH … Gold-facilitated ISH (GOLDFISH) was subsequently developed to detect amplification of the HER2 gene in paraffin-embedded breast carcinoma sections.

c,eDual-probe HER2/CEP17 ratio < 2.0; with an average HER2 copy number ≥6.0 signals/cell Equivocal for HER2 is defined as: IHC 2+ or FISH HER2/CEP17 ratio of 1.8-2.2 or average HER2 gene copy number 4-6 HER2 signals/nucleus for test systems without an internal control probe Must report HER2 test result as equivocal and order reflex test

FISH Analysis for HER2 amplification for breast and gastric cancers.

Results were compared to NordiQC FISH data from reference laboratories to analyze scoring consensus. Consensus scores from the NordiQC BRISH/FISH reference laboratories HER2 fIsH pharmDx™ Kit is a fluorescence in situ hybridization assay that quantitatively determines HER2gene amplification in formalin-fixed, paraffin-embedded (ffPe) breast cancer tissue and ffPe specimens from patients with adenocarcinoma of the stomach, including gastroesophageal junction. 2015-10-09 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 – FISH: Ratio <2.0 and <4 average Her2 copies per cell (was ratio <1.8) • Equivocal: – Immunohistochemistry: ≤10% intense membrane staining (was <30%) – FISH: 4 to 5.9 average Her2 copies per cell (was ratio 1.8 -2.2) • Positive: – Immunohistochemistry: >10% intense membrane staining (was ≥30%) – FISH: Ratio ≥2.0 or ≥6 A new HER2 test may (no longer should) be ordered on the excision specimen on the basis of some criteria (such as tumor grade 3). A more rigorous interpretation criteria of the less common patterns that can be seen in about 5% of all cases when HER2 status in … 2020-07-16 The interpretation of HER2 results must be semi-quantitatively evaluated in order to be useful for treatment planning.

The HER2 gene copy number is specified, and the HER2/chromosome 17 ratio is 2013-12-30 · 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. The overall concordance rate between HER2 immunohistochemistry and FISH was 75% (39/52) when using the FDA criteria, compared with 81% (42/52) by the ASCO/CAP scoring system. In conclusion, in this largest comprehensive study, 35% of endometrial serous carcinoma harbors HER2 protein overexpression and/or gene amplification, over half of which demonstrate significant heterogeneity of protein Se hela listan på neogenomics.com In contrast to IHC and FISH results, the analysis of HER2 amplification by real‐time PCR strongly increased the HER2 positive fraction from 5.0% (IHC and FISH) to 22.5%. This could imply that the IHC and FISH procedures underestimate HER2 status.
