Clinical evaluation of the CrossNN DNA methylation classifier for central nervous system tumors
Brain Pathology, EarlyView.CrossNN demonstrated non‐inferiority to the Heidelberg CNS Tumor Methylation Classifier. A dual‐classifier approach increased the number of clinically informative classifications with correct tumor type assignment while maintaining a low rate of incorrect predictions.

Brain Pathology, EarlyView.C3aR expression in IDH‐wildtype glioblastoma is predominantly associated with the myeloid/macrophage compartment and heterogeneous macrophage states. C3aR‐high tumors are enriched among MGMT promoter‐methylated tumors and show improved overall survival, although the prognostic association requires independent validation.

Immunohistochemistry as a tool for identifying PDGFRA amplification in central nervous system tumors
Brain Pathology, EarlyView.PDGFRA gene amplification is now recognized as a diagnostically and prognostically relevant molecular alteration in central nervous system tumors. Herein, we demonstrated that PDGFRA immunohistochemistry is a highly specific and sensitive biomarker for identifying PDGFRA amplification and should be part of the neuropathologist's routine panel of ...

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.ABSTRACT Rare cancers collectively represent 20%–25% of all malignancies yet yield fewer than 50 annotated whole‐slide images (WSIs) per subtype in publicly available archives, rendering supervised deep learning inapplicable. We present HierAnom‐Path, to the best of our knowledge, the first framework for zero‐shot rare cancer anomaly detection in ...
