Figure 3: Oct2, BCL6 and IRF8 expression at diagnosis predicts prognosis in DLBCL patients. Overall survival Kaplan-Meir curves for Oct2 (A), BCL6 (B) and IRF8 (C). Patients with a high percentage of Oct2, BCL6 or IRF8 stained nuclei cells (more than 70%) had a poor outcome in terms of shorter overall survival.
