Artificial Intelligence (AI) Image Analysis for Chromosomal Instability (CIN) in Primary and Metastatic Breast Cancers (BC)

Measures of CIN yield phenotypic features that can be robustly identified by AI analysis of H&E WSI in primary and metastatic BCs. Subtype stratification of BC was robust with respect to AUC and more readily detectable in primary than in metastatic BC. This study provides the basis for development of AI-based tools to detect CIN not only in breast cancer but across cancer types, and a means to test CIN broadly within clinical trials.

Artificial Intelligence (AI) Assisted Detection of Microsatellite Instability Mismatch Repair Deficiency (MSI-H dMMR) in Multiple Tumor Types from Whole Slide Images (WSI) of H&E Sections

Paige trained an AI-assisted digital pathology assay for MSI-H/dMMR from WSIs of H&E-stained sections in CRC (AUC 0.939) and GC (AUC 0.905). Validation in CRC and GC from TCGA and PAIP datasets confirmed generalization to unseen external data. These results compare favorably to prior digital assays for MSI-H in CRC and GC.
