Abstract

The human epidermal growth factor receptor (HER) family plays a critical role in the development, migration, and invasion of various cancers. Currently, the FDA has approved numerous targeting therapies for the HER family consist of small molecule drugs, monoclonal antibodies and antibody-drug conjugates. To facilitate precision therapy using currently approved targeted agents, early detection and quantification of each HER receptor are essential for assessment, treatment, and prognostic purposes. This study provides a comprehensive review of the latest advancements in detection and quantification of HER receptors, including traditional biopsies, liquid biopsies, and non-invasive detection methods. Although traditional histological methods, such as immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH), have yielded valuable insights, advancements in real-time and non-invasive detection technologies necessitate improved methods for the dynamic evaluation of HER status. This article also reviews several emerging real-time techniques for detecting and quantifying HER status in circulating tumor cells (CTCs) extracted from blood samples, as well as in vivo assessments using positron emission tomography (PET) and single-photon emission computed tomography (SPECT) imaging. This review emphasizes the importance of continuous innovation in the application of HER receptor imaging technologies, with the goal of enhancing treatment outcomes and prognoses for cancer patients.
