According to the updated 2018 HER2 testing guidelines, compared with HER2 FISH group 3 and group 4, which are currently recognized as HER2 positive and negative respectively, the much rarer FISH group 2, particularly IHC-equivocal (2+) cases within the group, were so exceptionally infrequent that it was extremely difficult to assign a HER2 status due to a lack of ample evidence.

2020-04-28 · FISH-EQUIVOCAL HER2 (ERBB2) amplification. ERBB2 (a.k.a. HER2) testing must be requested on every primary invasive breast cancer. Additionally, it is recommended to perform ERBB2 testing on metastatic sites, classified as stage IV, if tissue sample is available. Use of fixatives other than 10% formalin or fixation times less than six hours or more than 48 hours may not yield reliable results.

Why Get a FISH Test At the 2020-01-21 · FISH testing is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene. The more copies of the HER2 gene that are present, the more HER2 receptors the cells have. These HER2 receptors receive signals that stimulate the growth of breast cancer cells. Recently, the 2013 ASCO/CAP guidelines recommend either using IHC assays for initial evaluation of HER2 status followed by reflex testing by FISH of certain IHC categories, or the primary use of FISH in initial testing (18). The agreement between IHC 3+ and FISH amplification should be ≥95% (17).
Cleveland Clinic Laboratories offers HER2 gene amplification analysis of breast carcinoma by interphase fluorescence in situ hybridization (FISH) assay of paraffin-embedded tumor sections. Performance and interpretation of the assay are done in accordance with ASCO/CAP guidelines for HER2 testing (reference below). If aneusomy of chromosome 17 is
To compare the FISH and DISH methods, we tested 251 samples enriched for common or difficult-to-assess HER2 anomalies.
