Influence of ERG expression on outcome in childhood acute lymphoblastic leukemia patients. (A) Patients with low ERG expression had inferior RFS (P=0.036). Kaplan-Meier analysis demonstrated that estimated 5-year RFS rate for low ERG expressers was 58%, whereas the estimated 5-year OS rate for high ERG expressers was 79%. (B) No significant difference in OS was observed between the high and low ERG groups (B) (P=0.62). ERG, ETS-related gene; RFS, relapse-free survival; OS, overall survival.
