Towards robust foundation models for digital pathology.

PathoROB benchmark quantifying FM robustness in digital pathology to non-biological variations (lab protocols, scanner hardware)

This Nature Communications study introduces PathoROB, a public benchmark quantifying foundation model (FM) robustness in digital pathology to non-biological variations — particularly differences in laboratory protocols and scanner hardware. These variability sources pose real clinical deployment risks as FMs may learn non-biological features. PathoROB provides a standardized tool to assess robustness pre-deployment.

FM deployment in digital pathology is hampered by the lack of robustness standards — a high-performing model in development may fail on a different scanner or slightly modified staining protocol. PathoROB fills this critical methodological gap and should become a validation standard for clinical deployment.
