Figure 4From: Gene expression profiling of cholangiocarcinoma-derived fibroblast reveals alterations related to tumor progression and indicates periostin as a poor prognostic markerMultivariate analysis using Kaplan-Meier method. Cumulative survival analysis showed significantly shorter survival time of the patients with high PN expression in fibroblasts when compared to those who had low PN expression in fibroblasts (P = 0.026).Back to article page
