A new study evaluated the robustness of computational pathology foundation models (PFMs) for prostate cancer grading when faced with real-world data variations. Researchers found that while PFMs perform well on data from the same collection site, their performance significantly drops when transferred to images from different sites. This indicates that large-scale pretraining alone does not ensure generalization across diverse clinical settings, and downstream model training data quality remains crucial. AI
