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 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 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

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.
