Om cancer är FISH positiv, kommer det troligen att svara till Tykerb. SpoT-Light-testet använder en fläck som gör att HER2 / neu-gener ändrar 

vissa bröstcancer producerar för mycket av proteinet HER2 på grund av en förändring i en gen som kallas HER2 / neu. Läkare använder FISKTESTET för att Fish testing görs av en patolog. En patolog är en expert som tittar 

A new HER2 test may (no longer should) be ordered on the excision specimen on the basis of some criteria (such as tumor grade 3). A more rigorous interpretation criteria of the less common patterns that can be seen in about 5% of all cases when HER2 status in breast cancer is evaluated using a dual-probe ISH testing. 5 With FISH testing, the results are quantitative instead of qualitative; tumors are interpreted as HER2 "negative" or "positive" by enumerating the HER2/neu gene copy number. Using FISH, they observed that 4 of the 10 cases that were analyzed showed HER2/neu gene amplification. They, however, observed no differences in prognosis between amplified and nonamplified tumors. p53 positivity was found in 58% of SDCs studied by Felix and colleagues 251 but did not correlate with the clinical course.

Pathology Report: A copy of the pathology report is required for HER2 testing (global cases only). Breast tissue results of FISH group 2, 3, or 4 will be reflexed to ERBB2 (HER2/neu) (HercepTest) with Interpretation by Immunohistochemistry, Tissue (ARUP test code 0049174). Additional charges apply. FISH, HER-2/neu with Reflex to IHC - The test would mimic (FISH, HER-2/neu Paraffin Block). The reflex code for Immunohistochemistry is currently available.

Methodology: Fluorescence in-situ hybridization (FISH) by FISH is designed to detect amplification of the ERBB2 (Her-2/neu) gene, That section was hybridized with fluorescent probes from the Vysis PathVysion (TM) HER2 DNA Probe K

The HER2 gene makes HER2 proteins (also sometimes referred to as HER2/neu proteins). HER2 proteins are receptors on breast cells. Normally, HER2 receptors help control how a healthy breast cell grows, divides, and repairs itself. But in about 10% to 20% of breast cancers, the HER2 gene doesn't work correctly and makes too many copies of itself HER2 gene amplification is a permanent genetic change.

Normally, HER2 receptors help control how a healthy breast cell grows, divides, and repairs itself. But in about 10% to 20% of breast cancers, the HER2 gene doesn't work correctly and makes too many copies of itself HER2 gene amplification is a permanent genetic change. The excess copies of the HER2 gene result in the continuous overexpression of the HER2 protein on the cell surface.

Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in a person’s cells. This test can be used to visualize specific genes or portions of genes. FISH testing is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene.
