Evidence of Epstein-Barr virus (EBV) infection in patients continues to be associated with the development of various lymphomas, and EBV genomic regions are detected in some lymphoma cells. Its role in causality and progression of disease versus the role of a passenger continues to be debated. Several reports of Asian T-cell lymphomas have also associated these diseases with evidence of EBV infections. Asian T-cell lymphomas are clinically distinct from Western T-cell lymphoma, and are also associated with increased levels of cytokine production, including tumor necrosis factor (TNF). The current study reports correlations of EBV + T-cell lymphoma with higher levels of TNF, and suggests some prognostic correlations.

Tumour 'bulk' has historically been considered an important prognostic marker and clinical tool to guide treatment in patients with lymphoma. However, its use and definitions in trial designs varies significantly and it is unclear how this has influenced the relevance of bulk in contemporary practice. This comprehensive literature review evaluated the definitions, applications and prognostic impact of bulk in phase 3 randomised trials in four major lymphoma subtypes.

While it is the most common non-anaplastic mature T-cell lymphoma of childhood, it is quite rare and therefore, the standard of care remains largely undefined. It is a disease characterized by clinical and pathological heterogeneity and is generally associated with an aggressive clinical course and poor prognosis in adults.

Epcoritamab, a bispecific T-cell engager (BiTE) antibody targeting CD3 and CD20, has shown significant efficacy in treating refractory diffuse large B-cell lymphoma (DLBCL). However, its use can lead to severe side effects, such as tumor flare. Here, we report the case of an 84-year-old male with relapsed DLBCL who developed fatal unilateral pleural effusion following Epcoritamab treatment.

Background: Post-transplant lymphoproliferative disease (PTLD) is a significant complication that can arise following solid organ transplantation or hematopoietic stem cell transplantation. It encompasses a spectrum of lymphoproliferative lesions, ranging from benign reactive hyperplasia to malignant tumors, and is among the most severe complications following liver transplantation in children. It is essential for clinicians to gain a comprehensive understanding of the prevention, clinical manifestations, early diagnosis, and treatment strategies for PTLD in order to reduce mortality rates.
