Introduction: Histone deacetylase inhibitors (HDACi) and combination chemotherapy are independently used to treat relapsed/refractory (R/R) lymphoma. In vitro studies suggest that the addition of HDACi to platinum-based chemotherapy is synergistic.

Patients And Methods: We conducted a phase I study of romidepsin, gemcitabine, oxaliplatin and dexamethasone (Romi-GemOxD) in R/R aggressive lymphomas with an expansion cohort in T-cell lymphomas.

Treatment for relapsed/refractory (R/R) follicular lymphoma (FL) has evolved over recent years with the introduction of multiple novel immunotherapies: anti-CD3  ×  CD20 bispecific antibody (BsAb) T-cell engagers and anti-CD19 chimeric antigen receptor T cells (CAR T). Both drug classes are highly active, and their adverse event profiles overlap considerably, with cytokine release syndrome, cytopenias, and infections being most common. However, key differences include accessibility and logistical considerations as well as distinct neurologic toxicities, which make recommending a BsAb or CAR T a nuanced decision for each patient with R/R FL.

Mosunetuzumab and other CD20/CD3 bispecific antibodies (BsAbs) have efficacy in B-cell lymphomas relapsing after or refractory to CD19-directed chimeric antigen receptor-modified T cells (CAR-T). The optimal timing of BsAbs and biomarkers of BsAb response after CAR-T are unknown. We addressed these questions using clinical data and blood samples from patients previously treated with CAR-T treated on a phase I/II study of mosunetuzumab (clinicaltrials.

Article Synopsis
  • Ongoing research is essential for tracking and understanding the emergence of new SARS-CoV-2 variants, particularly as diagnostic testing declines in Australia during the COVID-19 pandemic.
  • In 2023, collaborations with pathology and genomics teams allowed for the monitoring of SARS-CoV-2 variants in New South Wales through various methods, including viral culture and analysis of immune responses from a large pool of blood donations.
  • Findings indicated that while existing antibodies generally neutralized many variants, specific mutations in emerging strains, particularly JN.1, suggested future challenges in controlling their spread due to enhanced transmissibility.

Marginal zone lymphoma (MZL) can have varied presentations and pathologic features, including high Ki-67 expression ( > 20%) as well as increased numbers of large B cells (LC). However, there are limited data available demonstrating the prognostic significance of these variables in patients with MZL. In this multi-institutional retrospective cohort study of patients with MZL treated at 10 centers, we evaluated the association between the presence of Ki-67 expression and increased LCs on survival and risk of histologic transformation (HT).

Introduction: Submersion results in blood redistribution into the pulmonary circulation, causing changes in pulmonary compliance and increased cardiac preload. Few studies have compared incremental exercise to exhaustion (VO max testing) in a dry environment with exercise underwater. We hypothesized that the physiological effects of submersion would result in lower heart rate (HR), minute ventilation (V), and peak oxygen uptake (VO peak) compared with dry conditions.

The role of frequently touched surfaces in the transmission of infectious diseases is well-documented, and the urgent need for effective surface technologies with antipathogen activity has been highlighted by the recent global pandemic and rise in antimicrobial resistance. Here, we have explored combinations of up to 3 different classes of compounds within a polymeric matrix to enable the fabrication of coatings with broad-spectrum activity. Compounds were either based on metals or metal oxides, namely, copper, silver, and copper oxide, essential oils, namely, cinnamaldehyde, tea tree oil, and carvacrol oil, or cationic polymers, namely, poly(ε-lysine) and poly(hexamethylene biguanide).

Although initial therapy of mantle cell lymphoma (MCL) is not standardized, bendamustine plus rituximab (BR) is commonly used in older patients. Rituximab (R) maintenance after induction is often used. Thus, the open-label, randomized phase 2 ECOG-ACRIN Cancer Research Group E1411 trial was designed to test 2 questions: (1) does addition of bortezomib to BR induction (BVR) and/or (2) addition of lenalidomide to rituximab (LR) maintenance improve progression-free survival (PFS) in patients with treatment-naïve MCL? From 2012 to 2016, 373 previously untreated patients, 87% aged ≥60 years, were enrolled in this trial.

Although it is evident that standard-dose whole-brain radiotherapy as consolidation is associated with significant neurotoxicity, the optimal consolidative strategy for primary central nervous system lymphoma (PCNSL) is not defined. We performed a randomized phase 2 clinical trial via the US Alliance cancer cooperative group to compare myeloablative consolidation supported by autologous stem cell transplantation with nonmyeloablative consolidation after induction therapy for PCNSL. To our knowledge, this is the first randomized trial to be initiated that eliminates whole-brain radiotherapy as a consolidative approach in newly diagnosed PCNSL.
