MTOR and gastric cancer: Kaplan-Meier analysis showed that diffuse-type GC patients with strong p-mTOR expression had a significantly worse prognosis than those with weak p-mTOR expression (n = 227; P = 0.044; Fig. 4d), while significant differences were not found in non-diffuse type GC patients (n = 377; P = 0.485; Fig. 4b).
