N2 - Background & Aims: Cholangiocarcinoma (CCA) displays remarkable anatomical and histological heterogeneity. Besides diagnosis confirmation, histology currently does not have a major role in the management of CCA. We aimed to study the clinical relevance of histological heterogeneity of CCA and putative tissue biomarkers by creating a multicentric digitalized European CCA Histology Registry. Approach & Results: Nine referral centers, participating in the International Cholangiocarcinoma clinical registry, shared samples and data from 293 patients. Histological and immunohistochemistry stains (n=10) were performed. Computed tomography (CT) scans (n=112 cases) were analyzed by morphological and radiomics techniques. A selection of cases (n=18) was processed for spatial transcriptomics analysis. No significant differences in 5-year overall survival (OS) were found in perihilar CCA vs intrahepatic (i) CCA, and in Small Bile Duct (SBD) vs Large Bile Duct (LBD) iCCA. When cases were classified by periodic acid of Schiff (PAS) positivity (mucin content), PASHIGH LBD iCCA showed a significantly worse 5-year OS compared to PASLOW iCCA. Multivariate Cox regression identified PASHIGH LBD iCCA phenotype as an independent predictor of a worse OS. PASHIGH LBD iCCA subtype showed specific molecular characteristics at spatial transcriptomics and immunohistochemistry; CT scans and serology could distinguish PASHIGH LBD iCCA phenotype with excellent accuracy. Conclusions: Our data underline the importance of identifying morphological subclasses with a significant prevalence in CCA as a tool for risk stratification and prognosis. The European CCA Histology Registry represents a valuable platform for integrating digital pathology with clinical, radiological, and molecular information as a framework for digital twin advancement.
