Chromogenic in situ hybridization (CISH) is a reliable method for detecting HER-2 gene status in breast cancer - USCAP2008; Chromogenic in situ hybridization (CISH): A practical method to confirm the immunohistochemical (IHC) results for HER-2 amplification in archival breast carcinoma sample Interpretation der Her-2/neu-Immunhistochemie. the tumour cells is observed. more than 10% of the tumour cells. The cells are only stained. in part of their membrane. observed in more than 10% of the tumour cells. more than 10% of the tumour cells In conclusion, SISH represents a novel approach for the determination of HER2 status in breast cancer. The overall concordance between SISH and FISH is excellent, and the interpretation of SISH results by pathologists is most reproducible using the HER2/CHR17 ratio CISH / FISH. Die In-situ-Hybridisierung (ISH) ist eine Methode zum Nachweis von spezifischen DNA- und RNA-Sequenzen direkt auf dem histologischen Schnittpräparat (in situ). Die nachzuweisenden Sequenzen können virale RNA oder DNA sein oder auch Translokationen, Deletionen und Amplifikationen von humanen Genen beinhalten Interpretation of staining results in breast cancer Breast carcinomas that are considered positive for HER2 protein overexpression must meet a threshold criteria for the intensity and pattern of membrane staining (3+ on a scale of 0 to 3+), and for the percent positive tumour cells (greater than 10%).

Chromogenic in situ hybridization (CISH) is the only FDA approved single probe ISH test for HER2 Quantitative reverse transcription polymerase chain reaction can also be used (Am J Clin Pathol 2008;129:563) Immunohistochemistry (IHC) detects evidence of protein overexpression via evaluation of the membranous staining in the tumor cell HER2/neu (human epidermal growth factor receptor 2, offizieller Name: ERBB2, erb-b2 receptor tyrosine kinase 2) gehört zur Familie der epidermalen Wachstumsfaktorrezeptoren (EGF-Rezeptor). HER2/neu stimuliert die Zellproliferation über den RAS-MAP-Kinase-Weg und hemmt den programmierten Zelltod (Apoptose) über den mTOR-Signalweg We assessed Her-2/ neu alteration using CISH on formalin-fixed paraffin-embedded primary invasive ductal carcinoma tumors in which IHC (CB11 antibody) had previously been performed, and we compared the results with IHC. The 160 selected cases were equally stratified randomly into the four IHC categories (scores of 0, 1+, 2+, and 3+) testing measures the HER2/neugene copy number against a standard internal chromosomal control (CEP 17). Results are expressed as a ratio of the number of HER2 gene copies (orange) per number of chromosome 17 copies (green). 3 A normal ratio is less than 2 (FISH-). 3 A ratio greater than or equal to 2 HER2/neugene copies per chromosome 17 is gene CISH or SISH has been used to detect a single DNA target (Fig. 7.2), but detecting multiple targets required using serial sections. For example, one slide is stained for HER2 gene target and the next is stained for CEN17 target. Ideally, both HER2 and CEN17 targets should be detected simultaneously on the same slide to more accurately determine the ratio of HER2/CEN17, particularly the tumor heterogeneity

Die HER2-Testung kann sowohl an Biopsien als auch an Resektaten durchgeführt werden. Die frühzeitige Kenntnis des HER2-Status ist letztlich nicht nur für den Einsatz einer zielgerichteten Therapie entscheidend, sondern auch für die Auswahl des optimalen Chemotherapieregimes. Wird eine Chemotherapie begonnen, bevor der HER2-Status bekannt ist, kann zu einem späteren Zeitpunkt ein Wechsel des zunächst initiierten Chemotherapieregimes erforderlich sein Bei der HER2-FISH Analyse wird untersucht, ob das Brustkrebs-relevante Gen HER2 verstärkt aktiv (amplifi-ziert) ist oder nicht.

A French multicenter, cross-sectional, histopathological study assessed the concordance of HER2 status determined by immunohistochemistry and silver (SISH) or chromogenic in-situ hybridization (CISH) on core-needle biopsies with HER2 status determined by fluorescence in-situ hybridization (FISH) on surgical specimens. The concordance between biopsy and operative results was also assessed for each method. We studied 260 breast tumors from 24 centers between April 2003 and August 2009. Similar to immunohistochemical analysis, CISH allows detection of HER2 gene copy signals with a conventional peroxidase reaction and enumeration of the HER2 signals with simultaneous histologic examination by ordinary bright-field microscopy. 21 However, the reliability of CISH needs to be validated, ideally with large series of cases and tested at different sites This study shows a strong concordance between FISH and dc-CISH techniques and indicates that dc-CISH is a good alternative method for HER-2 gene amplification assessment in breast cancer.

Fluorescence in situ hybridization or CISH for HER2 gene amplification has become an integral part of the diagnostic workup for patients with breast cancer. The principles of in situ hybridization are simple: DNA probes complementary to genomic sequences of interest are generated, labeled, and then hybridized to the target tissue. Fluorescence in situ hybridization/CISH methods can be applied to a wide range of samples: cell lines, frozen tissue, paraffin-embedded tissue, and. The Genetic Testing Registry (GTR) provides a central location for voluntary submission of genetic test information by providers.

For the 89 invasive breast cancer cases, the overall rate of con- cordance between consensus 4B5 and consensus SISH, fluorescence ISH, and chromogenic ISH was 96.6% (86/89), 97.8% (87/89), and 96.6% (86/89), re-spectively. Overall concordance between positive and negative SISH and fluorescence ISH results. Amplification of the HER2 gene, present in 15-30% of breast carcinomas, correlates with poor outcome and is an indication for treatment with trastuzumab. Standard testing methods for HER2 amplification are fluorescence (FISH) or chromogenic in situ hybridization (CISH). In FISH/CISH scoring, correction for chromosome 17 polysomy is believed to be critical for determination of true HER2. CISH results were successfully obtained from all fifty PDAC cases. According to the CISH Test Interpretation Guide, HER2/neu gene amplification was detected in 8/50 cases (16%). In 3 of those amplified cases, more than 10 scattered dots and/or large clusters, representing scattered or accumulated gene copies, respectively, were detected in.

interobserver differences in interpretation of HER2 IHC result are also important issues (1, 15, 17, 18, 22, 23). Overexpression of the HER2 protein generally ( 95%) results from HER2 gene.

How is HER2 FISH testing for breast cancer interpreted

Roche launches new VENTANA HER2 Dual ISH companion diagnostic test for breast and gastric cancer patients eligible for targeted therapy. Basel, 23 April 2019. Nearly 2.1 million new cases of breast cancer are diagnosed worldwide each year, and more than 620,000 people will die from the disease. 1 About 15 to 20 percent of women diagnosed with breast cancer are HER2 positive. 2; The VENTANA. The study by van de Vijer et al was not the first to identify that assessment and interpretation of HER2 cases with very low level of amplification (6-10 signals per cell) benefit from inclusion of the chromosome 17 probe. Inclusion of the chromosome 17 probe in such cases had proved to be robust and reproducible between other laboratories.64 A correlation of 100% was found between CISH and. Name. HER2 is so named because it has a similar structure to human epidermal growth factor receptor, or HER1. Neu is so named because it was derived from a rodent glioblastoma cell line, a type of neural tumor. ErbB-2 was named for its similarity to ErbB (avian erythroblastosis oncogene B), the oncogene later found to code for EGFR.Molecular cloning of the gene showed that HER2, Neu, and ErbB.
