Deep learning prediction of pathological complete response in breast cancer using Mamba architecture

A deep learning model helps predict which breast cancer patients will respond completely to chemotherapy before treatment starts, across multiple hospitals.

A novel Mamba-architecture deep learning model predicts pathological complete response to neoadjuvant chemotherapy in breast cancer from routine needle biopsy images with AUROC up to 0.923 in training and 0.761-0.809 across four independent external hospital cohorts. This multi-hospital validation across 1646 patients suggests clinical readiness for decision-support integration to help tailor NAC regimens.

What the study was

Study design
Multi-center retrospective validation study
Population
Breast cancer patients receiving neoadjuvant chemotherapy (NAC), 5 Chinese tertiary hospitals
Sample size
1646 patients (1023 training/validation, 623 external test across 4 hospitals)
Category
Diagnostics
Maturity
Validated
Journal
NPJ Digital Medicine

Why it surfaced

Large multi-center validation (n=1646) of a novel Mamba-architecture AI model for predicting breast cancer pCR after NAC. Robust external validation across 4 independent hospitals is a strong signal of clinical applicability. pCR prediction has direct treatment decision implications (surgery timing, regimen continuation/change).
