Abstract. Human epidermal growth factor receptor 2 (HER2) overexpression is increasingly recognized as a frequent molecular abnormality in gastric and 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 receptor (PR), and human epidermal growth factor receptor-2 (Her2). Breast cancer has four main subtypes: luminal A, luminal B, basal-like, and HER2- positive. Der HER2-Rezeptor kann Paare bilden (Dimerisierung) und zwar sowohl mit Testergebnis.

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 tissue to determine if the cancer is HER2-positive. 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.

HER2-positive breast cancers have abnormally high levels of HER2 receptors, whereas HER2-negative breast cancers don’t. There are a few differences between HER2-positive and HER2-negative breast cancers, including the tumor's risk factors, its biology, and its anticipated aggressiveness. In other cases, tissue from one area of a breast cancer can test HER2-positive and tissue from a different area of the cancer can test HER2-negative. Inaccurate HER2 test results may cause women diagnosed with breast cancer to not get the best care possible. If all or part of a breast cancer is HER2-positive but test results classify it as HER2-negative, doctors aren't likely to recommend anti-HER2 treatment — even though the woman could potentially benefit from those medicines. Under current treatment guidelines, breast cancer is categorized as HER2-positive or HER2-negative. However, some investigators use the term HER2-low expressing (or HER2-low expression) in clinical trials and research to describe HER2-negative tumors that test IHC 1+ or 2+ and FISH-.
