Zymeds  Methods and results: We found 100% agreement between HER2 status determined by FISH and dual-colour CISH. Furthermore, we observed that the time used  Herceptin är indicerat för behandling av patienter med HER2-positiv ett starkt HER2 överuttryck klassificerat som 3+ med IHC eller ett positivt FISH eller CISH-.

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-

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).

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).

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.

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.
