HMGA2 is a highly sensitive marker for DICER1‐related tumours

Histopathology, EarlyView.
Aims DICER1 is a microRNA biogenesis enzyme that, when mutated, results in a rewiring of the transcriptome. Germline pathogenic variants (PVs) in DICER1 result in DICER1‐related tumour predisposition (DRTP) characterized by 30 or more different, generally rare, paediatric or adolescent‐onset tumours.

HierAnom‐Path: Zero‐Shot Rare Cancer Detection in Histopathology via Hierarchical Foundation Model Adaptation

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 ...
