Abstract

Triple-negative breast cancer (TNBC) is a rare cancer, characterized by high metastatic potential and poor prognosis, and has limited treatment options. The current standard of care in nonmetastatic settings is neoadjuvant chemotherapy (NACT), but treatment efficacy varies substantially across patients. This heterogeneity is still poorly understood, partly due to the paucity of curated TNBC data. Here we investigate the use of machine learning (ML) leveraging whole-slide images and clinical information to predict, at diagnosis, the histological response to NACT for early TNBC women patients. To overcome the biases of small-scale studies while respecting data privacy, we conducted a multicentric TNBC study using federated learning, in which patient data remain secured behind hospitals' firewalls. We show that local ML models relying on whole-slide images can predict response to NACT but that collaborative training of ML models further improves performance, on par with the best current approaches in which ML models are trained using time-consuming expert annotations. Our ML model is interpretable and is sensitive to specific histological patterns. This proof of concept study, in which federated learning is applied to real-world datasets, paves the way for future biomarker discovery using unprecedentedly large datasets.

  • Ogier du Terrail and colleagues presented a federated learning approach for predicting response to neoadjuvant chemotherapy in triple-negative breast cancer.

    “A recent study by Ogier du Terrail and colleagues (83) presented a federated learning approach for predicting response to neoadjuvant chemotherapy in triple-negative breast cancer.”
  • That approach used weakly supervised training to predict response from H&E whole slide images and interpretability methods identified features correlating with higher response predictions, such as TILs and necrosis.

    “The approach included weakly supervised training to predict response from H&E whole slide images, with subsequent application of interpretability approaches to identify features that correlate with higher response predictions, such as the presence of tumor-infiltrating lymphocytes (TILs) and necrosis.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
