HER2-FISH Analyse Bei der HER2-FISH Analyse wird untersucht, ob ein Brustkrebs-relevantes Gen, das Gen HER2 (auch c-erbB2 genannt) verstärkt aktiv (amplifiziert) ist oder nicht. Ist dies der Fall, profitieren die betroffenen Patientinnen von einer Therapie mit dem monoklonalen Antikörper Trastuzmab, der unter dem Handelsnamen Herceptin ® bekannt ist.

HER2/neu status in breast cancer specimens: Comparison of immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) methods. Int. J. Morphol., 33(2):737-742, 2015. 739 Keywords: HEr2/NEu, Breast carcinoma, IHC, FISH, Cytogenetics INTRODUCTION Breast cancer is one of the most common malignancies according to the global cancer statistics with high incidence and mortality of breast cancer all over the world.1 India accounts for nearly six percent of deaths due to breast cancer globally.

The HER2/neu gene (also known as ERBB2) is located on chromosome 17 (q11.2-q12) and encodes a glycoprotein known to be a member of the epidermal growth factor receptor family. Clinically, the determination of its amplification status is of utmost importance, as 10-35% of invasive human breast carcinomas come along with HER2/neu overexpression, and treatment has to be adjusted accordingly.

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. This test can be used to visualize specific genes or portions of genes.

Neu is so named because it was derived from a rodent glioblastoma cell line, a type of neural tumor. ErbB-2 was named for its similarity to ErbB (avian erythroblastosis oncogene B), the oncogene later found to code for EGFR. Molecular cloning of the gene showed that HER2, Neu, and ErbB-2 are all encoded by the same orthologs. Gene

They, however, observed no differences in prognosis between amplified and nonamplified tumors.

HER2/neu is the human epidermal growth factor receptor 2, also called ERBB2 (Erb-B2 receptor tyrosine kinase 2) HER2 gene encodes transmembrane growth factor receptor (p185) Cytoplasmic tyrosine kinase is constitutively active when overexpressed due to homo / heterodimerization (International Seminars in Surgical Oncology 2008;5:9)

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. 2016-07-27 2018-07-12 FISH is performed using PathVysion (Abbott Molecular, Inc) probes to the HER2 locus (17q11.2-q12) and the chromosome 17 centromere (D17Z1). Results are reported as a HER2:D17Z1 copy number ratio and interpreted according to ASCO/CAP guideline recommendations. 2020-07-16 HER2 FISH Testing for Breast Cancer Complete Breast and Gastric Cancer Care.
