Device Validation of Augmented-Reality ICG Fluorescence Imaging for Sentinel Lymph Node Detection in Breast Cancer

28. juni 2026 oppdatert av: Borislav Kondov, Ss. Cyril and Methodius University of Skopje

Validation of Augmented-Reality/Virtual-Reality Goggle-Based Near-Infrared Fluorescence Imaging for Sentinel Lymph Node Detection in Patients With Breast Cancer

This study evaluates how accurately augmented-reality goggles with indocyanine green (ICG) near-infrared fluorescence can identify sentinel (first-draining) lymph nodes during breast cancer surgery. The goggles and ICG signal are used to mark candidate sentinel nodes, and an additional observer may record near-infrared images during the operation for device-performance assessment. These imaging findings do not change the surgical procedure. The candidate nodes and all removed tissue are examined by histopathology, which serves as the reference standard. Two hundred patients undergoing breast cancer surgery will take part. The study measures how well the goggle-based imaging detects nodes that contain cancer, compared with final pathology.

Studieoversikt

Detaljert beskrivelse

This is a prospective observational device-validation study in patients undergoing breast cancer surgery with axillary evaluation. Augmented-reality goggle-based near-infrared fluorescence imaging with ICG is used to visualize and mark candidate sentinel lymph nodes. Intraoperative near-infrared imaging may be performed by an observer who is not the operating surgeon, solely to assess device performance; observer findings are not communicated to the operating surgeon before wound closure and do not influence the operation. All marked nodes and removed tissue undergo histopathology, which serves as the blinded reference standard. Device performance is assessed on consecutive eligible patients within defined enrollment windows; for each near-infrared imaging device, sensitivity, specificity, positive and negative predictive value, and node-level ROC analysis are estimated against final histopathology, with confidence intervals accounting for clustering of nodes within patients. The study is non-interventional: the imaging does not alter surgical management.
