HER2 gene amplification and receptor prevalence correlates with poor breast HER2 IQFISH pharmDx is a direct fluorescence in situ hybridization (FISH) 

HER2-positive and HER2-negative refer to two different types of breast cancer. In recent years, there have been significant developments in the treatment of HER2-positive breast cancer. Learn more

If your cancer is HER2/neu positive, you may respond to a specific drug that targets HER2/neu receptors. Results for IHC: A score of 0 or +1 means your tumor is HER2 negative. HER2 assessment is routinely used to select patients with invasive breast cancer that might benefit from HER2-targeted therapy. The aim of this study was to validate a fully automated in situ hybridization (ISH) procedure that combines the automated Leica HER2 fluorescent ISH system for Bond with supervised automated analysis with the Visia imaging D-Sight digital imaging platform.

FISH test results are reported as either negative or positive. FISH negative means that the levels of the HER2 gene in the cells are normal, and the tumour is HER2 negative.. FISH positive means that there is at least 4 copies of the HER2 gene in the cells, and the tumour is HER2 positive.. HER2-positive cancers are more aggressive, which means that they tend to grow and spread more quickly

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.

Positive means your breast cancer cells make too much HER2 and your doctor should treat you with drugs that target that protein. 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. Equivocal HER2 amplification: FISH ratio of 1.8-2.2 or HER2 gene copy of 4.0-6.0. Negative HER2 HER2 är ett protein som i vissa fall finns i ökad mängd på cancercellernas yta. FISH-mätningen bekräftar att HER2-är positiv. HER2 signalerar en viss grad av aggressivitet, men erbjuder även möjligheten att behandla med specifika antikroppar, Trastuzumab tillsammans med cytostatika.

2019年12月16日 決定是否可以使用HER2標靶治療的關鍵第一步，就是透過免疫組織化學染色（IHC ）或是螢光原位雜交（FISH）方法來準確地判斷HER2是否有 

FISH: HER2 per tumore alla mammella 20 Agosto 2020 Il tumore della mammella è la neoplasia più frequente per incidenza nella donna, rappresentando il 29% di tutti i tumori della popolazione femminile. 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. HER2 equivocal status by FISH was defined as a HER2/CEP17 ratio of 1.8–2.2.

Create a Lean 2020-04-28 If your cancer is HER2/neu positive, you may respond to a specific drug that targets HER2/neu receptors. Results 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.

Performance and interpretation of the assay are done in accordance with ASCO/CAP guidelines for HER2 testing (reference below).
