DuoCISH is a variation of CISH that addresses the need for two different probes on the same slide. 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.

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.

However, for the chromogenic method to achieve status as a safe and reliable technique, the method needs to be validated against already known and validated FISH techniques. Here it is reported from a comparative study where HER2 gene Appendix A: HER2 CISH test interpretation guide HER2 gene amplification Amplification High amplification: >10 dots, or large clusters, or a mixture of multiple dots and large clusters of the HER2 gene present per nucleus in >50% cancer cells.

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.
