DCLK1 and gastric adenocarcinoma: In addition, high DCLK1 expression in the tumor tissues also predicted poor overall survival (OS; p = 0.021 for colon adenocarcinoma (COAD) and p = 0.0002 for stomach adenocarcinoma (STAD)), and progression-free survival (PFI) (p = 0.0086 for COAD and p < 0.0001 for STAD) (Figure S1A–D).
