Abstract
Our objective was to evaluate the non-germinal center (GC) profile as a marker for response and survival in DLBCL and to compare the characteristics of patients with GC and non-GC DLBCL treated with rituximab-containing regimens. In this patient-level meta-analysis, retrospective data from 712 newly diagnosed DLBCL patients treated with chemoimmunotherapy from 7 centers were analyzed. GC and non-GC profiles were defined according to the Hans algorithm. Although the non-GC profile showed a trend towards worse overall survival (HR 1.24, 95% CI 0.92-1.66; p = 0.15) and progression-free survival (HR 1.29, 95% CI 0.96-1.73; p = 0.09), it did not retain its value in the multivariate survival analysis. Additionally, the non-GC profile was independently associated with worse complete response rates (OR 0.55, 95% CI 0.37-0.83; p < 0.01) in the multivariate logistic regression analysis. Interestingly, Asian patients had higher proportion of GC DLBCL (p = 0.01).
