Chromogenic in situ Hybridization (CISH) and Silver enhanced in situ Hybridization (SISH) A simple and practical alternative to FISH that does not depend on expensive fluorescence microscopy instrumentation and expertise has been developed and refined since 2000 and is called Chromogenic in situ Hybridization (CISH).

Aim of this study was to compare prognostic relevance of HER2 status in MBC tested by two different methods i.e. immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH). HER2 status of the same group of 107 MBC patients was determined by IHC (protein overexpression) and by CISH …

SPOT-Light® HER2 CISH Kit Cat. # 84-0150 20 tests using 24 mm x 30 mm coverslips Intended use For in vitro diagnostic use The SPOT-Light® HER2 CISH Kit is intended to quantitatively determine HER2 gene amplification in formalin-fixed, paraffin-embedded (FFPE) breast carcinoma tissue sections using chromogenic in situ hybridization (CISH) CISH is a recent advancement in Her-2/ neu detection. It uses a robust unique-sequence probe developed for in situ hybridization and is a promising practical alternative to FISH. After the first CISH study by Tanner and colleagues [ 21 ], seven other reports favorably validated CISH results [ 22 – 28 ]. The importance of HER2 status in breast cancer management has focused attention on the ability of clinical assays to correctly assign HER2 amplification status. There is no consensus as to the best method for assessing HER2 status. Disadvantages of fluorescence in situ hybridization (FISH) testing i … Chromogenic in situ hybridisation (CISH) is similar to FISH in that it identifies the degree of HER2 gene amplification, and has the same advantages of a DNA-based assay.

Seven cases with IHC score 0 were amplified at CISH. FISH analysis revealed an amplification in 5/42 cases (12%). The HER2 genetic testing was performed using 5 assays: HER2 CISH pharmDx Kit-SK109, HER2 FISH pharmDx Kit-K5331, HER2 IQ-FISH pharmDx-K5731 (Dako, Denmark), ZytoDot 2C SPEC HER2/CEN17 Probe Kit-C-3022-40 and SPEC HER2/CEN17 Dual Colour Probe Kit-Z-2020 (ZytoVision, Germany).

The CISH technique uses digoxigenin-labeled DNA probes that are specific for the HER2 gene locus on chromosome 17q11.2-21 to hybridize to the complementary nucleic acids present in the breast cancer specimen. The labeled HER2 probe is made using Subtraction Probe Technology (SPT™), a proprietary and patented technology

2021-03-18 2021-03-12 2013-07-22 HER2-CISH, Breast Cancer The Human Epidermal Growth Factor Receptor 2 (HER2) is a central biomarker in invasive breast cancer, and the HER2 status has both important prognostic implications, and is predictive for the patient’s response to HER2-targeted treatment. In 2008, FDA approved another test, the SPOT-Light HER2 CISH Kit, for use with Herceptin, but Herceptin’s labeling does not mention this assay by name (Approval Letter for P050040, 2008). Tykerb (lapatinib), which also treats breast cancer tumors overexpressing HER-2, was approved in 2007 for use after failure of Herceptin ( Approval Letter from Richard Padzur, 2007 ).
