Expression profiling of 224 gene predictors and the prognosis of patients. A: Hierarchical clustering using 224 gene predictors of patients with or without HCC recurrence. Patients with HCC recurrence within 2 years are shown in red and patients with HCC recurrence after the cessation of peretinoin are boxed in red. B: Pathway analysis of differentially expressed genes using MetaCore (GeneGo). Functional ontology enrichment analysis was performed to find differentially expressed pathway maps or map folders using 224 differentially expressed genes (p<0.002) between patients with and without HCC recurrence. C, D: Kaplan-Meier estimation of recurrence-free ratio (C) and survival ratio (D) of patients with recurrence expression patterns (red) and those with non-recurrence expression (blue).
