Kaplan-Meier survival curves for patients with intrahepatic cholangiocarcinoma. Patients without nodal or distant disease (N0M0) were stratified according to T-classification using the LCSGJ system (A) and Okabayashi system (B). Additionally, for all patients including those with nodal metastases and distant disease, the LCSGJ staging system (C) is shown. [Used with permission by Nathan et al.
