23 cases out of a total of 34 PB-DLBCL patients were further divided into GCB type (11 cases) and non-GCB type (12 cases), with 5-year OS rates of the 2 groups being 70.1% and 20.0% respectively, but the apparent difference did not reach statistical significance ( P = 0.193) and also for PFS there was no statistical significance ( P = 0.299). 20 patients received combined rituximab treatments, but compared with the group without rituximab, OS and PFS were not significantly different (5-year OS 48.4% vs 60.6%, P = 0.494; 5-year PFS 44.9% vs 44.0%, P = 0.432).
