However, cancer cells that have extra copies of the HER2 gene create too much of the HER2 protein. HER2-targeted treatments such as trastuzumab, pertuzumab or lapatinib may be part of the treatment plan for patients with HER2-positive cancer. Peripheral Blood: N/A. They dont take into account individual factors or very recent advances in treatment. Paraffin-embedded tissues are cut at 5 microns and mounted on positively charged glass slides. The standard of care is to test all breast cancers for HER2 status. WebThere are various tests to measure HER2 levels. For assistance, contact. Reports also interpret the HER2 copy number changes relative to chromosome 17 copy number (aneusomy) or potential structural genomic abnormalities that increase HER2 copy number. J Clin Oncol. tenderness, heaviness, or dull pain in both breasts. WebIf you get an IHC test for HER2 receptors, the lab gives your doctor a number for a result: 0 or 1+ means your breast cancer doesnt have receptors for HER2. What are the results of my HER2 test? Use of fixatives other than 10% formalin or fixation times less than six hours or more than 48 hours may not yield reliable results. Fluorescence in situ hybridization with labeled DNA probes to the pericentromeric region of chromosome 17 and to the HER2 locus can be used to determine if a patient's breast cancer has HER2 gene amplification. The results of HER2 testing are included in a pathology report. The DR thinks it's Stage IIB, maybe Stage III. During a surgical breast biopsy, a doctor will remove all or part of the breast lump. Targeted therapy drugs bind to specific proteins on or in cancer cells.

HER2 testing provides information about a patients prognosis, which relates to how the cancer is most likely to behave. Currently, immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), and chromogenic in situ hybridization (CISH) including silver in situ hybridization (SISH) are regarded as standard methods for determination of HER2 status in breast cancer, and some of them have been approved by The results are interpreted based on the 2018 guidelines established by the American Society of Clinical Oncology (ASCO) and College of American Pathologists (CAP). As such, treatments for HR-positive breast cancers often targets hormone receptors. FISH testing is done on breast cancer tissue removed during biopsy to see if the cells have extra copies of the HER2 gene. It may be helpful to ask your doctor about whether HER2 testing is appropriate for your diagnosis. This means their tumor cells have many copies of the HER2 gene (also called human epidermal growth factor receptor 2, HER2/neu, or ERBB2). You may be wondering if having HER2-negative breast cancer is better than having HER2-positive breast cancer. Get the latest articles about breast cancer sent to your inbox. Perez EA, Roche PC, Jenkins RB, et al: HER2 testing in patients with breast cancer: poor correlation between weak positively by immunohistochemistry and gene amplification by fluorescence in situ hybridization. This is why its important to reassess these markers if a cancer recurs. Clinically used breast cancer markers such as estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 are unstable throughout tumor progression [Abstract]. FISH results are usually available within a few days. Human epidermal growth factor receptor 2 (HER2) is a protein thats found on the surface of breast cells. Because triple-negative breast cancer lacks both HER2 and hormone receptors, it doesnt respond to treatments that target these factors. The selection of tissue and the identification of target areas on the hematoxylin and eosin (H and E)-stained slide are performed by a pathologist.
