As we take a closer look at this technological revolution, it becomes evident that AI can help sort out the tricky parts of traditional assessments and offer an objective, consistent evaluation of HER2 scores.

Understanding HER2 Testing and Its Tricky Parts

HER2, or human epidermal growth factor receptor 2, is a protein that plays a super important role in the growth and spread of certain aggressive breast cancers. Traditionally, HER2 levels have been measured using immunohistochemistry (IHC) and in situ hybridization (ISH). These conventional methods, however, come with a set of tangled issues. The process often involves manually reviewing slides to determine whether a tumor is HER2-positive or HER2-negative. Many pathologists encounter confusing bits when differentiating between the subtle gradations of HER2 expression, such as the low levels that now demand special attention.

Recent studies have highlighted the significance of identifying patients with “HER2-low” breast cancer—a group that, while exhibiting lower protein expression, might benefit from targeted therapies. With new treatment options emerging, the need to get into the fine points of HER2 scoring has never been more crucial. This is where AI steps in to help figure a path through the subtle differences present in each sample.

AI Image Analysis: Cutting Through the Confusing Bits in Pathology

AI-assisted image analysis is emerging as a promising solution to reduce the nerve-racking variability inherent in manual scoring. By processing high-resolution digital slides, AI algorithms analyze minute details that can be missed by the human eye. In one notable study led by Krishnamurthy and colleagues, the Galen Breast HER2 AI algorithm was put to the test in clinical settings spanning three countries. This algorithm, developed by Ibex Medical Analytics, uses a multi-step process to assess whole-slide images with a level of precision that helps overcome the intimidating challenges of conventional HER2 testing.
