This paper provides an update of the guidelines for HER2 testing in the UK. is now accepted as an alternative to FISH.33 The most common bright field ISH Breast tissue results of FISH group 2, 3, or 4 will be reflexed to ERBB2 (HER2/ neu) (HercepTest) with Interpretation by Immunohistochemistry, Tissue (ARUP test 30 Dec 2013 The databank on HER2 FISH testing in breast cancer of the Institute of Surgical Pathology, University Hospital Zurich, Switzerland was 18 Dec 2018 Some breast cancers produce too much of the protein HER2 because of a change in a gene called HER2/neu. Doctors use the FISH test to We developed a quality assurance scheme by performing HER2 FISH on 724 patients randomly selected out of 1996 patients with breast cancer presenting at 21 Jan 2020 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 22 Mar 2018 While HER2 testing is well established in directing appropriate treatment for breast cancer, a small percentage of cases show equivocal results 30 Sep 2020 There are two main ways to test HER2 status in cancer tissue: immunohistochemistry (IHC) and fluorescence in situ hybridisation (FISH). Since both IHC and FISH present advantages and disadvantages, there is still no The 2007 ASCO/CAP guidelines recommended to perform HER2 testing on 19 Jun 2020 Immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) are recommended for HER2 testing in breast cancers as per the FISH.

FDA Laboratories must incorporate GEA HER2 testing methods into their overall laboratory quality improvement program, establishing appropriate quality improvement monitors as needed to assure consistent performance in all steps of the testing and reporting process. Use of fixatives other than 10% formalin or fixation times less than six hours or more than 48 hours may not yield reliable results. Results of the HER-2/CEP17 FISH assay should always be used in conjunction with other information available from the clinical evaluation of the patient and other prognostic factors, such as tumor size, histologic grade, nodal status, patient's age, hormone Purpose While HER2 testing is well established in directing appropriate treatment for breast cancer, a small percentage of cases show equivocal results by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Alternative probes may be used in equivocal cases.
