Combined Morphological and Spectroscopic Diagnostic of HER2 Expression in Breast Cancer Tissues Based on Label-Free Surface-Enhanced Raman Scattering

Abstract: Breast cancer is the most commonly diagnosed cancer type worldwide. Overexpression of human epidermal growth factor receptor 2 (HER2) is an important subtype of breast cancer and results in an increased risk of recurrence and metastasis in patients. At present, immunohistochemistry (IHC) is used to detect the expression of HER2 in breast cancer tissues as the golden standard. However, IHC has some shortcomings, such as large subjective impact, long time consumption, expensive reagents, etc. In this paper, a co… Show more

“…Mo and coworkers developed a strategy for the recognition of HER2 expression in breast cancer tissues using a combined morphological and spectroscopic method via label-free SERS ( Fig. 5 a) [ 163 ]. The approach presented in the study enables not only quantitative detection of HER2 expression but also provides information on the spatial distribution of HER2 in breast tissue.…”

“…Indeed, the binding event ampli es the HER2 Raman signal, making easily detectable even the smallest amounts. This combination of selectivity, sensitivity, and molecular speci city renders SERS a breakthrough technique for the detection and quanti cation of membrane biomarkers, particularly HER2 in BC [23,24]. Therefore, while Arti cial Intelligence (AI)-assisted Raman spectroscopy can provide an e cient cell discrimination and identify the speci c metabolic signature of cancer cells, SERS analysis can provide a detailed visualization of the distribution of biomarkers on the cell surface.…”

“…The information obtained by Raman spectroscopy and SERS complements each other and enables a synergistic enrichment of the clinical relevance of the collected data. Nonetheless, despite the numerous works carried out, either on classi cation of BC cell lines using Raman spectroscopy [17,18,[25][26][27] or HER2 detection using SERS strategies [24,28], a combined SERS-Raman approach for BC cells analysis and HER2 expression assessment has not been investigated so far.…”
