Amplification of 9p24.1, causing PD-L1 overexpression, plays a significant role in EBV-positive DLBCL and EBV-positive cHL, whereas EBVMCU, DLBCL-CI, FA-DLBCL, and LyG primarily depend on an (local) immunosuppressive condition. In conclusion, the molecular pathogenesis of EBV LPD is less reliant on driver mutations and instead rely on EBV latent genes and immune evasion; both factors provide promising targets for future therapy.
In vitro proteomics showed their impact on key oncogenic pathways, revealing significant enrichment of replication and transcription-related proteins. Interpretation and conclusions The expression of miR-193b-5p, miR-1307-5p, and miR-671-5p miRNAs in diffuse large B-cell lymphoma tissues may serve as predictive biomarkers.
This study provides valuable real-world insight into the clinical landscape of DLBCL in Saudi Arabia. Overall outcomes are consistent with international data, although older age and comorbidities remain associated with poorer prognosis. As advanced therapies such as chimeric antigen receptor T-cell therapy and bispecific antibodies become more available, further improvements in survival are expected. These findings underscore the need for a national lymphoma registry and continued investment in research infrastructure to guide evidence-based, personalized care.

A patient with biopsy-proven VRL underwent longitudinal vitreous cytokine analysis during intravitreal methotrexate (MTX) and dexamethasone (DEX) therapy. Co-expression of IL-10 and IL-May 16, reflect a dynamic interaction between lymphoma cells and the TME, contributing to immune modulation and treatment resistance. Longitudinal IL-16 monitoring may provide additional insight into disease activity and therapeutic response; however, this requires validation in larger VRL cohorts, ideally including inflammatory controls.
Functional studies in DLBCL cell lines further confirmed that TAp73 enhances sensitivity to serum deprivation and doxorubicin, whereas ΔNp73 overexpression promotes survival and chemoresistance...Functional studies showed TAp73 sensitizes DLBCL cells to stress and chemotherapy, while ΔNp73 enhances resistance. These findings highlight ΔNp73 as a potential biomarker and therapeutic target in DLBCL.
