Purpose: In the literature, substantial differences have been reported regarding incidence and outcomes for the pediatric and adult groups with non-Hodgkin’s lymphoma (NHL). Diffuse large B cell lymphoma (DLBCL) is the most common NHL subtype, and its outcome in adolescents and young adults (AYA) has not been widely investigated. This study aims at reporting our experience on the outcome of DLBCL in the AYA group. Methods: One hundred twenty DLBCL patients, 40 AYA patients, and 1:2 matched 80 control non-AYA patients were diagnosed and followed up at our center included. Results: In both groups, the median progression-free survival (PFS) and overall survival (OS) were not reached, without any difference between groups (p = 0.7, p = 0.7, respectively). The median follow-up time was 28 (range 1–133) months in all patients. In both groups, international prognostic index scores and early relapse were associated with worse PFS and OS, but in the non-AYA group, the immunohistologic type was, in fact, related to worse outcomes. Conclusion: DLBCL in AYA is a predominantly overlooked subject, due to the rarity of the disease. The outcome of DLBCL in this age group is not encouraging, which not only needs to be further investigated, but novel approaches must also be developed.
