Figure 4.

Survival curves and cumulative incidences of distance metastases after surgery. Patients in cohort 1 (left) and cohort 2 (right) were stratified according to the immunohistochemical (IHC) scores with cutoff values of a score of 6 for phosphorylated mammalian target of rapamycin (p‐mTOR) and a score of 3 for phosphorylated S6 ribosomal protein (p‐S6). The overall survival (A), the relapse‐free survival (B) and the distant metastasis rate (C) for patients with p‐mTOR and p‐S6 expression scores lower than each cutoff score are represented by red lines, and those for patients with expression scores equal to or higher than each cutoff score are represented by blue lines
