We aimed to refine HCA natural history according to an updated molecular classification. Methods 607 samples of 533 HCA from 411 patients collected in 28 centers were systematically analyzed by expression profiling and sequencing 20 and 8 genes, respectively. Microarray analysis, RNA sequencing, whole-exome and genome sequencing were performed in selected cases. Clinical and pathological features were compared with molecular data. Results Symptomatic bleeding occurred in 14% of the patients (female 85%, median age 38 y), 7% of the nodules were borderline between adenoma and carcinoma (HCA/HCC) and in 3% HCC developed on HCA. We defined a new molecular classification of HCA in 8 molecular subgroups. Among them, we identified a new HCA subgroup (4%, previously unclassified) associated with obesity and bleeding. These tumors were characterized by a sonic Hedgehog pathway activation due to focal deletions creating INHBE promoter/GLI1 fusions. Analysis of inter-tumor genetic heterogeneity of multiple HCA in patients revealed a "molecular subtype field effect" with tumors harboring private mutations leading to similar pathway deregulation. Specific molecular HCA subtypes were associated with various risk factors and estrogen/androgen hormonal balances. Finally, the molecular classification enabled to stratify patients according to the risk of bleeding and malignant transformation. Conclusion INHBE-GLI1 fusion defined a new subgroup of HCA characterized by sonic hedgehog activation. Molecular classification identified subgroups of patients related to specific risk factors, clinical behavior and pathological features laying the foundations for personalized treatment.
