2019-12-05 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. J Clin Oncol. 2016 Oct 10;34 (29):3518-3528. doi: 10.1200/JCO.2016.66.6693. HER2 gene amplification analysis is offered specifically as a prognostic and predictive molecular marker for invasive breast carcinoma and as an adjunctive test in the manage-ment of patients with advanced breast carcinoma for whom therapy with trastuzumab is contemplated. FISH also may be useful as a confirmatory reflex assay for breast carcinoma METHODS: A total of 122 gastric cancer cases scored IHC 2+ were retrospectively analyzed for HER2 amplification by fluorescence in situ hybridization (FISH).

FISH also may be useful as a confirmatory reflex assay for breast carcinoma METHODS: A total of 122 gastric cancer cases scored IHC 2+ were retrospectively analyzed for HER2 amplification by fluorescence in situ hybridization (FISH). The correlation between HER2/neu expression and clinicopathologic features was analyzed. RESULTS: HER2/neu gene was amplified in 17 out of the 122 gastric cancer samples.

6 *Vysis PathVysion® If A Patient is IHC 2+ or 3+ and FISH-, are they HER2+? Overexpression of the HER2 protein rarely occurs in the absence of gene amplification.10 FISH has also been successfully done on unfixed cells. A target-specific probe, composed of 20 oligonucleotide pairs, hybridizes to the target RNA(s). Separate but compatible signal amplification systems enable the multiplex assay (up to two targets per assay).

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).We retrospectively assessed the impact of these new guidelines by using annotated Breast Cancer International Research Group (BCIRG) -005, BCIRG-006, and BCIRG-007 2020-04-28 HER2 gene amplification status was classified according to the guidelines of the American Society of Clinical Oncology and College of American Pathologists (ASCO/CAP). Comparison of the cut-off values for HER2/chromosome 17 centromere copy number ratio obtained by NMFISH and FISH showed that there was almost perfect agreement between the two methods (κ coefficient 0.920).

The patient was randomly assigned to BCIRG-005 (BCIRG01911, original magnification, ×1,000). BCIRG/TRIO central laboratory reportedthe case asHER2 not ampliﬁed byFISH, with anaverage HER2 gene copy number of 4.22 per tumor cell, an average CEP17 copy number of 2.23 per tumor cell, and, Test Usage This test detects amplification of the HER2 gene via fluorescence in situ hybridization (FISH) in formalin-fixed, paraffin-embedded breast cancer tissue specimens. FISH is performed using PathVysion (Abbott Molecular, Inc) probes to the HER2 locus (17q11.2-q12) and the chromosome 17 centromere (D17Z1). HER2 Gene Amplification by Fluorescence In Situ Hybridization (FISH) Compared With Immunohistochemistry (IHC) in 122 Equivocal Gastric Cancer Cases. Liu X(1), Wang X, Wang B, Ren G, Ding W. Author information: (1)Department of Pathology, The First Affiliated Hospital, College of Medicine, Zhejiang University, Hangzhou, Zhejiang, China. BCIRG/TRIO central laboratory reported the case as HER2 not amplified by FISH, with an average HER2 gene copy number of 4.22 per tumor cell, an average CEP17 copy number of 2.23 per tumor cell, and, therefore, an HER2 -to-CEP17 FISH ratio of 1.89.
