YAP1 and gastric cancer: As to the tumor type, we found that YAP1 high expression was associated with poor DFS in liver cancer (HR = 1.67, 95% CI (1.25, 2.23), P=0.001) and pancreatic cancer (HR = 1.95, 95% CI (1.30, 2.93), P=0.001), while colorectal cancer (HR = 1.74, 95% CI (0.77, 3.92), P=0.180), esophageal cancer (HR = 1.56, 95% CI (0.61, 3.97), P=0.351), and gastric cancer (HR = 1.02, 95% CI (0.49, 2.12), P=0.968) have no statistical difference.
