Artificial intelligence-driven pathomics in hepatocellular carcinoma: current developments, challenges and perspectives
Hepatocellular carcinoma (HCC) is a highly malignant tumor with elevated incidence and mortality rates globally. Its complex etiology and pronounced heterogeneity present significant challenges in diagnosis and treatment. Recent advancements in artificial intelligence (AI) have demonstrated transformative potential to usher a new wave of precision oncology. Pathomics, an AI-based digital pathology technique, facilitates the extraction of extensive datasets from whole-slide histopathological images, enabling quantitative analyses to improve diagnosis, treatment, and prognostic prediction for HCC. Despite its promise, pathomics research in HCC remains in its infancy, with clinical implementation hindered by challenges such as data heterogeneity, model interpretability, ethical concerns, regulatory issues, and the absence of standardized industry protocols.

Histological Classification
A pioneering effort by Cheng et al. introduced a DL model, HnAIM, for the differential diagnosis of seven types of hepatocellular nodular lesions (HNLs). This model demonstrated robust performance at both patch and slide levels, contributing to early diagnosis and risk stratification.

Genetic Marker Prediction
Zhou et al. demonstrated that a pathomics model could accurately predict the expression of Enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) and its associated prognosis in HCC.
Case Study: Predicting EZH2 Expression
Zhou et al. demonstrated that a pathomics model could accurately predict the expression of Enhancer of zeste 2 polycomb repressive complex 2 subunit (EZH2) and its associated prognosis in HCC.
- PM accurately predicted EZH2 expression with AUROC of 0.815 (training) and 0.742 (test).
- High pathomics scores (PSs) were associated with worse OS.
- Offers a cost-effective and reproducible approach for biomarker prediction.
