Diffuse large B-cell lymphoma (DLBCL) is the most frequently-occurring type of malignant lymphoma in the Western world. It has an aggressive natural history, with a median survival of less than one year if left untreated. Immunochemotherapy regimens, consisting of the anti-CD20 antibody rituximab typically in combination with cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP), are currently the treatment backbone. Despite remarkable progress in improving patient survival, clinical outcomes are still unsatisfactory for certain subsets of patients, including the elderly and very elderly and those with highly aggressive disease. This review outlines some of the current treatment strategies for DLBCL and discusses the main issues that affect clinical practice.

Differentiation of antigen-activated B cells into pro-proliferative germinal center (GC) B cells depends on the activity of the transcription factors MYC and BCL6, and the epigenetic writers DOT1L and EZH2. GCB-like Diffuse Large B Cell Lymphomas (GCB-DLBCLs) arise from GCB cells and closely resemble their cell of origin. Given the dependency of GCB cells on DOT1L and EZH2, we investigated the role of these epigenetic regulators in GCB-DLBCLs and observed that GCB-DLBCLs synergistically depend on the combined activity of DOT1L and EZH2.

Gemcitabine + oxaliplatin (GemOx) with rituximab, a standard salvage therapy, yields complete response (CR) rates of approximately 30% and median overall survival (OS) of 10-13 months. Patients with refractory disease fare worse, with a CR rate of 7% for subsequent therapies and median OS of 6 months.

The cell of origin (COO) classification is an expression-based tumor algorithm identifying molecular subtypes of diffuse large B-cell lymphoma (DLBCL) with distinct prognostic characteristics. Traditional immunohistochemical methods for classifying COO subtypes have poor concordance and limited prognostic value in frontline DLBCL. In contrast, RNA-based metrics like the NanoString Lymphoma Subtyping Test (LST) define more robust subtypes with validated prognostic associations.

Background: Patients with transplant-ineligible relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) have limited treatment options and poor outcomes.
Methods: This phase III study (NCT04236141) evaluated the efficacy and safety of polatuzumab vedotin plus bendamustine and rituximab (Pola+BR) versus BR in Chinese patients with transplant-ineligible R/R DLBCL to support regulatory submission in China. Patients were randomized 2:1 to receive Pola+BR or placebo+BR.
Enabling High-Voltage and Long Lifespan Sodium Batteries via Single-Crystal Layer-Structured Oxide Cathode Material.

Manganese-based layer-structured transition metal oxides are considered promising cathode materials for future sodium batteries owing to their high energy density potential and industrial feasibility. The grain-related anisotropy and electrode/electrolyte side reactions, however, constrain their energy density and cycling lifespan, particularly at high voltages. Large-sized single-crystal O3-typed Na[NiMnCuTi]O was thus designed and successfully synthesized toward high-voltage and long-lifespan sodium batteries.
