Disease-free survival (DFS) and overall survival (OS) curves of 112 ICC patients. a DFS curves of the 112 ICC patients show that patients with lower EYA4 protein levels, serum carbohydrate antigen 19-9 (CA19-9) level >37 U/L, serum CEA level >5 µg/L, multiple tumors, adjacent organ invasion, lymph node metastasis, and poor differentiation had worse DFS (all P < 0.05). b OS curves of the 112 ICC patients show that patients with lower EYA4 protein levels, serum CA19-9 level >37 U/L, serum CEA level >5 µg/L, multiple tumors, adjacent organ invasion, lymph node metastasis, and poor differentiation had worse OS (all P < 0.05)
