Kaplan-Meier survival curves show the comparison of patients with high
(enhancing tumor volume [ETV] ≥65 cm3 and enhancing
tumor burden [ETB] ≥4%) and low tumor burden (ETV <65
cm3 and ETB <4%) in (A, B) all
patients (the Barcelona Clinic Liver Cancer [BCLC] B + C group),
(C, D) only patients with BCLC B tumors, and (E,
F) only patients with BCLC C tumors.
