It is a well-established technique for HER-2/neu amplification detection even though it is sometimes reported to be less effective than FISH. 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. However, visualisation is achieved using a peroxidase-based chromogenic reaction, similar to IHC. HER2-positive breast cancer is when breast cancer cells have a protein receptor called HER2 (human epidermal growth factor receptor 2). Normally, this protein helps breast cells grow, divide, and In endometrial carcinoma, HER-2/neu gene status can be readily assessed by CISH in routine clinical practice, and it gives more prognostic information than HER-2/neu by immunohistochemistry. FISH analysis in (2+) cases but negative by CISH may detect additional tumours with low-level amplification.

Two parallel sets of 5-mm-thick, formalin-ﬁxed, paraﬃn-embedded sections were cut from the tumor blocks used for HER2 staining and examined by CISH using the Zymed protocol and our modiﬁed protocol with the Zymed Spot-Light HER2 CISH kit (84-0146, Zymed Laboratories, San 2020-09-21 2020-10-06 2014-01-09 The new VENTANA HER2 Dual ISH DNA Probe Cocktail assay is a fully automated, ready-to-use brightfield solution for determining HER2 gene status. VENTANA HER2 Dual ISH helps identify breast and gastric cancer patients eligible for treatment with HER2-targeted personalized therapies. Increased performance. Oligo probes and new detection kits At CISH analysis 10/37 cases (27%) were amplified, 6 cases with HER2 amplification showed positive HER2 IHC (3+, 2+, 1+). Seven cases with IHC score 0 were amplified at CISH.

HER2 proteins are found on the surface of breast cells. They’re involved in normal cell growth but can become “overexpressed.” This means Evaluating HER2 Gene Amplification Using Chromogenic In Situ Hybridization (CISH) Method In Comparison To Immunohistochemistry Method in Breast Carcinoma. Atabati H(1), Raoofi A(2), Amini A(3), Farahani RM(3). Author information: (1)Leishmaniasis Research Center, Sabzevar University of Medical Sciences, Sabzevar, Iran. 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.
