PIK3CA was significantly upregulated in gastric carcinoma and was prognostic for OS and DFS in gastric carcinoma.

Notes: (A) Immunohistochemistry (IHC) assays of PIK3CA expression in 107 paired gastric carcinoma and adjacent nontumorous tissues. Scale bars, 50 μm. (B) Box plot graph showing PIK3CA expression level compared among gastric carcinoma and adjacent nontumorous tissues. (C, D) Prognostic significance assessed by Kaplan–Meier survival estimates and log-rank tests. Comparison of OS and DFS by PIK3CA. P<0.05.

Abbreviations: OS, overall survival; DFS, disease-free survival; T, tumorous tissues; NT, nontumorous tissues.
