Overall survival (A) and disease-free survival (B) in 136 patients with PGC according to the expression levels of SOX4. The analysis with Kaplan-Meier method clearly showed that PGC patients having tumors with strong SOX4 expression (+++) had respectively increased overall (P = 0.008) and DFS (P = 0.01) compared with patients with negative (-), weak (+) or moderate (++) SOX4 expression.
