Background: HCC is one of the most prevalent and deadliest malignancies worldwide, with a poor prognosis. Altered histone modifications have been shown to play a significant role in HCC. However, the biological roles and clinical relevance of specific histone modifications, such as the asymmetric dimethylation on arginine 3 of histone H4 (H4R3me2a), remain poorly understood in HCC. Methods: In this study, immunohistochemical staining was performed to assess histone H4R3me2a modification in 32 pairs of HCC tissues …

Colorectal cancer (CRC) is a leading malignancy worldwide, where histopathological assessment of hematoxylin and eosin (H&E) stained whole-slide images remains the diagnostic gold standard. However, current computational pathology models suffer from domain shifts, unreliable uncertainty estimation, and spurious correlations, limiting clinical reliability. We present UAD-FM, an Uncertainty-Aware and Causally Adaptive Foundation Model that integrates epistemic-aleatoric uncertainty decomposition, causal test-time ad…
