Pretreatment MRI reveals hidden breast cancer phenotype

Researchers have identified a latent structural phenotype in pretreatment MRI scans that influences breast cancer treatment outcomes, independent of molecular subtypes. This phenotype, termed structural entropy, was found to be a more robust predictor of treatment response and recurrence risk than conventional clinical and genomic data. The study suggests that while tumors may appear to shrink volumetrically, their underlying structural disorder can persist, potentially leading to a deceptive appearance of response. This discovery, validated across multiple datasets, highlights the importance of advanced imaging analysis for a more accurate understanding of treatment efficacy. AI

IMPACT This research could lead to more accurate cancer prognoses and personalized treatment plans by uncovering hidden patterns in medical imaging.

    Pretreatment MRI reveals a latent, molecular-subtype-independent structural phenotype that organizes treatment trajectories and recurrence risk

    arXiv:2607.02768v1 Announce Type: cross Abstract: Pathologic complete response and tumor shrinkage measure whether breast cancer responds to neoadjuvant therapy, but not whether that response was structurally favorable, persistent, or hidden beneath volume loss. We built an outco…
