Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in a person’s cells. This test can be used to visualize specific genes or portions of genes. FISH testing is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene.

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. Hormone therapy and drugs that target HER2 … The interpretation of HER2 results must be semi-quantitatively evaluated in order to be useful for treatment planning. (A) Breast tumors with either absent or partial weak membrane staining will typically demonstrate a normal HER2 gene status by FISH and are considered HER2 negative (scored as 0 or 1+).
Purpose ASCO and the College of American Pathologists (ASCO-CAP) recently recommended further changes to the evaluation of human epidermal growth factor receptor 2 gene (HER2) amplification by fluorescent in situ hybridization (FISH).
Fully automated Leica HER2 FISH. System for BONDTM. Contains PathVysion * FISH Probes supplied by Abbott Molecular Inc. 28 May 2015 Her2 amplification by FISH Pros and Cons of Her2 FISH. 12 FISH: Ratio <2.0 and <4 average Her2 copies per cell (was ratio <1.8). IHC 3+ and FISH positive results means you will be treated with medications that target HER2-positive breast cancers. Limitations. While important tests, there are FISH, HER-2/neu, Paraffin Block - HER-2 oncogene amplification in stage 2 lymph node positive breast cancer which aids in treatment selection and HER2 testing is usually done by immunohistochemical assessment of HER2 protein or by fluorescence in situ hybridization (FISH) analysis of the HER2 gene ERBB2 (HER-2) Amplification by FISH.
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
FISH Request AM PM AM PM Day 1 Day 2 AM PM AM PM Day 1 Day 2 AM Day 3 Dewax The Leica HER2 FISH System can deliver next day HER2 results, up to 24 hours faster than current HER2 workflow. Patient cases can be continuously processed on the Leica BOND System without the delay required to batch cases as in manual HER2 FISH staining.

If the FISH test comes back strongly positive for HER2, it is much more likely that a drug called trastuzumab (Herceptin) will work. Trastuzumab targets the HER2 protein.
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. Se hela listan på cancer.ca

HER2-FISH Analyse Bei der HER2-FISH Analyse wird untersucht, ob ein Brustkrebs-relevantes Gen, das Gen HER2 (auch c-erbB2 genannt) verstärkt aktiv (amplifiziert) ist oder nicht. Ist dies der Fall, profitieren die betroffenen Patientinnen von einer Therapie mit dem monoklonalen Antikörper Trastuzmab, der unter dem Handelsnamen Herceptin ® bekannt ist.
