Breastcancer.org: "HER2 Status," "How Triple-Negative Breast Cancer Behaves and Looks,” “Inform HER2 Dual ISH Test,” “SPoTLight HER2 CISH Test.” The human HER2 gene with the generic name ERBB2 (also known as NEU) encodes the HER2 protein or p185HER2. The HER2 protein is a membrane receptor tyrosine kinase with homology to the epidermal growth factor receptor (EGFR). The HER2 gene is a normal component present in two copies in all normal diploid cells. In a fraction of patients (15-20%) with breast cancer, the HER2 gene is amplified as This paper examined the concordance of human epidermal growth factor receptor 2 (HER2) status in core needle biopsy (CNB) specimens as determined by immunohistochemistry (IHC) or silver in situ hybridization (SISH), fluorescent in situ hybridization (FISH), or chromogenic in situ hybridization (CISH) with HER2 status of matched surgical resection specimens as determined by FISH as well as the CISH and HER2 FISH (Table 3) were HercepTest™ IHC 2+ equivocal cases, and the remaining three were 0, 1+ and 3+, respectively. The discordant cases had aHER2/ CEN-17 ratio very close to or within the borderline area defined from 1.8 and 2.2 for at least one of the three meth- 2011-12-14 2008-10-22 2018-06-19 Keywords: HER2, FISH, SISH, CISH, qPCR, Multicenter analysis Background HER2 overexpression occurs in 14% to 20% of early breast cancers.

The HER2 scoring, which is supported by a standardized and validated protocol, is considerably faster with a CISH test than with a FISH test. 2016-09-21 At CISH analysis 10/37 cases (27%) were amplified, 6 cases with HER2 amplification showed positive HER2 IHC (3+, 2+, 1+).

The resulting chromogens precipitate at the probe target site and can be detected under a standard bright-field microscope. HER2 stands for human epidermal growth factor receptor 2. HER2 proteins are found on the surface of breast cells.

• Chromogenic in situ hybridization (CISH) is a cytogenetic technique that combines the chromogenic signal detection method of immunohistochemistry (IHC) techniques with in situ hybridization. It was developed around the year 2000 as an alternative to fluorescence in situ hybridization (FISH) for detection of HER-2/neu oncogene amplification.

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. 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 cells In CISH, probes are labeled with an antigenic moiety and detected via antibodies conjugated to an enzyme, typically horseradish peroxidase (HRP) or alkaline phosphatase (AP), that catalyzes reactions of chromogenic substrates. The resulting chromogens precipitate at the probe target site and can be detected under a standard bright-field microscope.
