Pathology foundation models for training-free case retrieval in salivary gland tumors

The study investigates whether pathology foundation models can enable training‑free, content‑based retrieval of similar cases from digitized archives of salivary gland tumors. Using a region of interest from a whole slide image, the models retrieve morphologically similar cases and their ICD‑O codes without task‑specific training. Evaluation on 137 cases across 12 morphology categories shows that Atlas2 achieves the highest retrieval accuracy, with macro‑averaged F1 scores ranging from 69.0% to 76.6% across models.

WILSON - a pathology foundation model framework for patient-level analysis and diagnostic text generation

WILSON is a vision–language foundation model that represents whole‑slide images and multi‑slide patient cases as single multi‑magnification composite images. Trained on about 189,000 Mayo Clinic slides covering 42 organs and 829 diagnostic entities, it outperforms dedicated case‑level models on internal cohorts and matches slide‑level models while using far less compute. Fine‑tuning on triple‑negative breast cancer data improves histologic subtyping and lymphocyte grading, and the model retrieves diagnostic text with high recall and generates captions closer to report references than prior methods.

CRISP -- Clustering-Based Redundancy-Reduced Instance Sampling for Pathology Case Representation and Retrieval

arXiv:2605. 24253v2 Announce Type: replace-cross Abstract: Digital pathology archives increasingly contain multiple whole-slide images (WSIs) per case, capturing spatially distinct tumour regions and reflecting intrinsic morphological heterogeneity.
