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.

Home; Fish > Her2 Neu Fish The interpretation for HER2 FISH testing (HER2/CEP17 ratio and gene copy number) is given below: Positive HER2 amplification: FISH ratio is greater than 2.2 or HER2 gene copy is greater than 6.0. 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. The excess copies of the HER2 gene result in the continuous overexpression of the HER2 protein on the cell surface. 6 *Vysis PathVysion® If A Patient is IHC 2+ or 3+ and FISH-, are they HER2+?

Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than other breast cancers, but are much more likely to respond to treatment with drugs that target the HER2 protein . A FISH test that detects amplification of the HER-2/neu gene in human breast cancer tissue specimens. HER2-positive and HER2-negative refer to two different types of breast cancer. In recent years, there have been significant developments in the treatment of HER2-positive breast cancer. Learn more HER2 overexpression (by IHC or FISH) identifies patients who might derive benefit from HER2 targeted therapy Trastuzumab based chemotherapy in patients with HER2 overexpression results in prolongation in median survival, progression free survival, overall response rate, clinical benefit rate and duration of response (Lancet 2010;376:687) The second part involved reassessment of HER2 status in breast cancers from women accrued to BCIRG-005 (ClinicalTrials.gov Identifier NCT00312208) whose cancers had HER2-to-CEP17 FISH ratios of less than 2.0 and an average of 4.0 to 5.99 HER2 genes per tumor cell (ISH-equivocal) or cancers with FISH ratios of less than 2.0 and average HER2 gene copies less than 4.0 per tumor cell (ISH-negative HER2/neu遺伝子とは HER2/neu遺伝子はがん遺伝子のひとつであり、1986年にその配列が決定されました(1)。この遺伝子のコードする産物（HER2/neu タンパク）はチロシンキナーゼ活性をもつ分子量185kDaの細胞膜を貫通する受容体型タンパクであり、乳癌や卵巣がん・胃癌において高頻度に増幅または Wann ist eine HER-2/neu-FISH-Analyse nötig ?

The original tumours were cut into 0.5 cm blocks, fixed in buffered 4% formaldehyde, and embedded in paraffin. Paraffin blocks were sliced at 4 mm and stained with H&E2saffran (H&ES).
