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. 2018-07-02 · Press MF, Sauter G, Buyse M, et al. HER2 gene amplification testing by fluorescent in situ hybridization (FISH): comparison of the ASCO-College of American Pathologists guidelines with FISH scores used for enrollment in breast cancer international research group clinical trials.

1980’s 1992 1998. Herceptin created. Metastatic BC Trials. FDA 2018-03-22 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. A score of +3 means the tumor is HER2 positive.

Breast tumors with an equivocal HER2 IHC result need to undergo reflex testing by FISH to resolve the HER2 status, allowing clinical decisions to be made about adjuvant treatment. Breast cancers with diffuse intense circumferential membrane staining (so called “chicken-wire” pattern) in >10% of invasive tumor cells.

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. Repeat HER2 testing on a surgical specimen if the initially tested core biopsy is negative is no longer stated as mandatory.

ASCO and CAP also recommend either using IHC assays for initial evaluation of HER2 status followed by reflex testing by FISH of some IHC categories or primary use of FISH in initial testing.

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. FISH testing is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene.
