Kaplan-Meier survival curves for patients with and without PIK3R1Met326Ile mutations. (A) Progression-free survival of patients with PIK3R1Met326Ile was significantly shorter than that of patients without PIK3R1Met326Ile (p = 0.0407). (B) Overall survival of patients with PIK3R1Met326Ile was significantly shorter than that of patients without PIK3R1Met326Ile (p = 0.0125).
