Bei der Behandlung von Brustkrebs ist entscheident in welchem Stadium sich dieser befindet. Für HER2 werden 3 Stadien ausgewiesen Score 0 und 1+ bedeuten, dass nur wenige HER2-Rezeptoren vorhanden sind. Das Ergebnis wird als negativ gewertet. Score 2+ ist ein fraglicher Befund (mind. 10 Prozent der invasiven Krebszellen mäßig aber kreisförmig angefärbt), hier sollte durch eine weitere Diagnostik des Tumormaterials mit einem zusätzlichen FisH-Test das Ergebnis konkretisiert werden. Score 3+ ist eindeutig positiv. If the IHC result is 0 or 1+, the cancer is considered HER2-negative. These cancers do not respond to treatment with drugs that target HER2. If the IHC result is 3+, the cancer is HER2-positive. These cancers are usually treated with drugs that target HER2. 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.

Her2/neu. Her2 ist eine der typischen molekularbiologischen Abkürzungen, deren Herkunft sich meist kaum noch rekonstruieren lässt. Das Färbeergebnis wird als vierstufiger Score von 0 bis 3+ mitgeteilt. Für den Score werden die .

The IHC gives a score of 0 to 3+ that measures the amount of HER2 proteins on the surface of cells in a breast cancer tissue sample. If the score is 0 to 1+, it's considered HER2-negative. If the score is 2+, it's considered borderline. A score of 3+ is considered HER2-positive. If the IHC test results are borderline, it's likely that a FISH test will be done on a sample of the cancer.

Als HER2/neu bezeichnet man sowohl einen Wachstumsfaktor-Rezeptor als auch das zugehörige Gen auf Chromosom 17.

HER2-positive breast cancer is more aggressive and more likely to recur than HER2-negative breast cancer. Recurrence can happen any time, but it usually takes place within 5 years of treatment 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. Name. HER2 is so named because it has a similar structure to human epidermal growth factor receptor, or HER1. 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.

Human epidermal growth factor receptor 2 (HER2) overexpression is present in approximately 15% of early invasive breast cancers, and is an important predictive and prognostic marker. The substantial benefits achieved with anti-HER2 targeted therapies in patients with HER2-positive breast cancer have emphasised the need for accurate assessment of HER2 status HER2/neu status in CRC.

If a case has an average of ≥ 6.0 HER2 signals/cell with a HER2/CEP17 ratio of < 2.0, formerly diagnosed as ISH positive for HER2, a definitive diagnosis will be rendered based on additional work-up. If not already assessed by the institution or laboratory performing the ISH test, IHC testing for HER2 should be performed using sections from the same tissue sample used for ISH, and the slides.

(It is also known as ERBB2). In some cancers, especially breast cancer or cancers of the stomach and esophagus (gastroesophageal), the tumor cells have extra copies of the gene and excess amounts of the protein that it produces. Tumors in this category are known as HER2-positive and can be more aggressive and respond differently.

HER2 amplification was detected in 89% of IHC 3+ cases, 13% of IHC 2+ cases, and 4% of IHC 0 to 1+ cases. Accordingly, using FISH as the reference standard, the positive predictive value of a positive IHC test (3+) was 89%, and the negative predictive value of a negative test was 96%. Importantly, the positive predictive value of an indeterminate IHC score (2+) for detecting HER2 amplification.

HER2 IHC was conducted with Ventana anti-Her2/neu (4B5) rabbit monoclonal primary antibody (Ventana Medi-cal System, Tucson, AZ) and HER2 immunoreactivity was assessed on a scale of 0 to 3 using the GC consensus panel recommendations [17, 18]. H-scores were calculated based on the formula, (% tumor IHC 1+) + 2 (% tumor IHC 2+) + 3 (% tumor IHC 3+), meaning possible H-score values range from 0.

  1. Human epidermal growth factor receptor 2 (HER2) is an important prognostic and predictive factor in breast cancer. HER2 is overexpressed in approximately 15%-20% of invasive breast carcinomas and is associated with earlier recurrence, shortened disease free survival, and poor prognosis. Trastuzumab (Herceptin) a humanized monoclonal antibody targets the extracellular domain of HER2.
  2. HER2/neu may be made in larger than normal amounts by some types of cancer cells, including breast, ovarian, bladder, pancreatic, and stomach cancers. This may cause cancer cells to grow more quickly and spread to other parts of the body. Checking the amount of HER2/neu on some types of cancer cells may help plan treatment.

HER2—also sometimes referred to as HER-2 or Her-2/neu or erb-b2—is one of more than 100,000 genes found in the nucleus of all human cells. The HER2 gene helps cells grow, divide, and repair themselves. Every cell should have only two copies of the HER2 gene. If it has more than two copies (referred to as gene amplification), these extra genes result in there being too many HER2 protein. HER2/neu is routinely assessed on all invasive breast cancers in our laboratory. In the period May 2005 to July 2006, 60 consecutive breast cancers were consensus-scored by two pathologists as 2+ or 3+ for HER2/ neu (Dako protocol) (many more were negative for HER2/neu, but are not considered here). The original tumours were cut into 0.5 cm. Ertumaxomab (ertu) is a bispecific, trifunctional antibody targeting Her2/neu, CD3 and the Fcγ-receptors I, IIa, and III forming a tri-cell complex between tumor cell, T cell and accessory cells.

Eligibility for the trial is determined by an IHC score of 1 to 2+ and by a HER2-to-chromosome enumeration probe ratio of <2.0, which, together, document the presence of HER2 target receptors on the tumor cell surface and lack of HER2 gene amplification in the cell nucleus. 3 HER2/neu is over expressed in 20-25% of breast cancers. HER2 breast cancers are aggressive and are associated with poor prognosis. The aim of this study was to develop the clinical grade Lu-177-trastuzumab and its preliminary evaluation for specific tumor targeting in HER2 positive breast cancer patients. Trastuzumab was conjugated to bifunctional chelator, DOTA, and characterized for. In general, FISH testing is thought to be more reliable than IHC, but it is more expensive. Equivocal IHC results can be seen in 15% of invasive breast cancers, whereas equivocal HER2 FISH results are seen in less than 3% of invasive breast cancer specimens and those that had previously been considered HER2 positive.
