Independent predictive factors of disease-free survival (DFS) and overall survival (OS) by multivariate analysis (Cox proportional hazards model).

Notes: HR, hazard ratio; CI, confidential interval; DFS, disease-free survival; OS, overall survival; IHM, intrahepatic metastasis; EHE, extrahepatic extension. All experiments were replicated thrice with triplicate repeated measures within each replication for each time point.
