HGF and gastric cancer: In terms of progression-free survival, HGF high expressed, MET high expressed, and both HGF and MET high expressed gastric cancer patients have less optimistic prognosis (TCGA/HGF: HR = 3.58 (1.39-9.19), P = 0.0046, MET: HR = 1.61 (1.32-1.98), P <0.0001, and HGF/MET: HR = 1.61 (1.32-1.97), P <0.0001, Figure 2D-F).
