4-key-genes are poor prognostic predictors for ICC patients with adjuvant TACE. A The transcriptional levels of 4-key-genes were evaluated via qRT-PCR in 40 paired ICC specimens. B Kaplan–Meier curve suggested that ICC patients with adjuvant TACE tend to have poor overall survival if they had a high transcriptional level of the 4-key-genes. C Representative western blot analysis of ICC tumor tissues and paired paratumor tissues. D The 4-key-genes expression in TMA (71 ICC patients with adjuvant TACE). E Representative immunohistochemical images of 4-key-genes expression in TMA (magnification, 200 ×). (**p < 0.01, ***p < 0.001; T, tumor; P, paratumor)
