In the GIST-60 cohort, patients with PTEN low expression had significantly reduced DFS (mDFS, 43.73 months; 95% CI, 30.19 to not reached [NR]) compared with patients with PTEN high expression (mDFS, 117.95 months; 95% CI, 65.61 to NR; P = .0084). Here, PTEN is linked to gastrointestinal stromal tumor.
