Kaplan-Meier analyses of different subgroups. (A) Kaplan-Meier analysis of ABC (26 cases) and GCB (17 cases) DLBCLs. (B) Kaplan-Meier analysis of CD5⁺ (33 cases), CD5^-CD10⁺ (19 cases), and CD5^-CD10^- (44 cases) DLBCLs. The P values were obtained by a log-rank test. The overall survival of 96 cases could be analyzed. This showed that the overall survival for the CD5⁺ group was worse than that of the CD5^-CD10⁺ and CD5^-CD10^- groups (log-rank test, P = .023). There was no significant difference in the overall survival between the CD5^-CD10^- and the CD5^-CD10⁺ groups (log-rank test, P = .504). Expression profiling was performed for 46 cases, 43 of which could be analyzed for overall survival. This indicated that the overall survival for the ABC group was worse than that of the GCB group (P = .003).
