BTC is a rare and aggressive cancer in which accurate biomarker evaluation is critical for identifying patients who may benefit from HER2-targeted therapies.<\/p>\n<p>Conducted by investigators at CHA Bundang Medical Center and CHA Ilsan Medical Center in South Korea, in collaboration with Lunit researchers, the retrospective analysis included 309 HER2-stained whole-slide images from 291 advanced BTC patients treated between 2019 and 2022. Three board-certified pathologists independently evaluated HER2 expression, and their assessments were compared against AI-based scoring performed using Lunit SCOPE HER2.<\/p>\n<p>According to the study, complete agreement among pathologists was observed in 62.1% of light microscopy assessments and 63.4% of digital pathology assessments, reflecting the inherent variability in HER2 interpretation. Against this background, Lunit SCOPE HER2 achieved an overall concordance rate of 83.5% with pathologist-defined ground truth, indicating close alignment with expert-reviewed interpretations.\u00a0 The findings underscore the well-recognized challenges of HER2 interpretation in biliary tract cancer, particularly in cases with low or borderline expression, where variability among pathologists was more pronounced. Within this context, the study suggests that AI-based analysis may help support more consistent interpretation when integrated into digital pathology workflows.<\/p>\n<p>\u201cAccurate and consistent biomarker assessment is critical as precision oncology continues to expand into more complex and less common cancers,\u201d said Brandon Suh, CEO of Lunit. \u201cThis study shows that AI-powered pathology can closely align with expert pathologists in HER2 interpretation for biliary tract cancer, an area where variability has been a longstanding challenge. We believe AI can play a meaningful role in supporting more standardized and reproducible decision-making as new targeted therapies emerge.\u201d<\/p>\n<p>The full study, titled \u201cPathologist\u2013Artificial Intelligence Concordance in HER2 Interpretation for Advanced Biliary Tract Cancer: Intraobserver, Interobserver, and Human\u2013Artificial Intelligence Variability,\u201d is <a href=\"https:\/\/www.laboratoryinvestigation.org\/article\/S0023-6837(25)00169-2\/abstract\">available online in <em>Laboratory Investigation<\/em><\/a>.<\/p>\n<p style=\"text-align: center;\">###<\/p>\n<p><strong>About Lunit<\/strong><\/p>\n<p>Founded in 2013, Lunit (KRX: 328130) is a global leader on a mission to conquer cancer through AI.
