Her2 testning i magcancer: en praktisk metod - modern patologi
The reflex code for Immunohistochemistry is currently available. Subsequent to publication of the CAP/ASCO guidelines for HER-2/neu testing for breast cancer, clients have requested that Quest Diagnostics make this testing scenario available to meet the new guidelines set for implementation by December 2017-06-01 HER2 (Other) with Gastric scoring uses the 2016 CAP/ASCP/ASCO consensus guidelines for gastric/gastroesophageal adenocarcinoma for HER2 evaluation. Specimen Requirements Pathology Report: For global HER2 FISH cases we require a copy of the HER2 IHC pathology report (if it is not available to us in NeoLINK™). The case was reflexed to FISH [fluorescence ISH] due to “histopathologic discordance” and reported as equivocal. The HER2/D17Z1 (chromosome 17 centromere) FISH ratio was 1.4 (negative) “to be interpreted with caution” due to the average copy number signals per cell of HER2 … 2019-03-01 HER2 amplification is associated with accelerated disease progression and poor prognosis in malignancies afflicting women, e.g., in breast cancer and endometrial carcinoma 3-5. Amplification of the HER2/neu gene has been identified in 15–30% of breast cancer and endometrial cancer 6-8.

HER2 gene copy number is specified, and the HER2/chromosome 17 ratio is reported; a normal HER2/chromosome 17 ratio is equal to or less than 1.7 FISH analysis was successful in all the cases attempted. In mammoplasty samples, HER-2/neu interphase analysis showed 98.42% + 2.07 (range 95.00 - 100.00%) of the cells with orange to green ratio of less than 2, thus indicating no amplification, while 1.58% + 2.07 (range 0.00 - 5.00%) of the cells showed orange to green ratio of equal to or more than 2 thus indicating HER-2/neu amplification . HER2/neu is the human epidermal growth factor receptor 2, also called ERBB2 (Erb-B2 receptor tyrosine kinase 2) Perform HER2 FISH on the breast core Fluorescence in situ hybridization (FISH) is a test that “maps” the genetic material in a person’s cells.

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. Her2 Neu Positive By Fish.
Test Name FISH for HER2 Gene Amplification Ordering Mnemonic Her2-Neu Reference Range HER2 not amplified. HER2 gene copy number is specified, and the HER2/chromosome 17 ratio is reported; a normal HER2/chromosome 17 ratio is equal to or less than 1.7
If the IHC result is 2+, the HER2 status of the tumor is not clear and is called "equivocal." This means that the HER2 status needs to be tested with FISH to clarify the result.
