This week's episode accompanies the Review Series on Marginal Zone Lymphoma published in this week's issue of Blood. Associate editor, Dr. Philippe Armand interviews authors Dr. Juan Pablo Alderuccio and Dr. Ariela Noy on their contribution to this review series titled "The treatment of marginal zone lymphoma". The article is crucial in highlighting the clinically and biologically heterogenous nature of MZL diseases, and how current treatment options and available research do not allow for comprehensive MZL specific therapies. Drs. Alderuccio and Noy share their insights on specific avenues for the expansion of the MZL care landscape.

In this week's episode we've pulled a vault recording from 2025! Blood editor Dr. Laurie Sehn interviews authors Drs. David-Alexandre Trégouët and Johannes Schetelig on their research published in volume 146 issue 19 of Blood journal. Dr. Trégouët's study conducted a genome-wide association study supplemented by transcriptome and Mendelian randomization analyses to identify 28 loci and proteins associated with VTE recurrence risk. This work provides genomic evidence that inherited variants contribute to the risk of VTE recurrence, raising the possibility of a more personalized approach to the prevention of recurrent VTE. The study conducted by Dr. Schetelig and colleagues report the results of a long term trial on patients with poor-response AML, comparing outcomes between patients who received salvage chemotherapy versus immediate transplantation. With no difference in survival rates at 5 years, outcomes seem to be determined mainly by genetic risk factors, age, and comorbidities, therefore challenging the routine use of intensive remission induction before allogeneic transplant in patients with an available donor and underscore the need for novel therapeutic strategies for poor-risk AML.

In this week's episode, Blood editor Dr. James Griffin interviews authors Drs. Vincent Muczynski and Mark Geyer on their latest research published in Blood. Dr. Muczynski's research asks if there could there be a better gene than the factor VIII (FVIII) gene to transfer for curative treatment of hemophilia A? Dr. Geyer then explores CAR T cells armed with interleukin-18 (IL-18) secretion that target CD371, a transmembrane glycoprotein with high expression on AML and leukemia-initiating cells. Both studies explore finding novel targets for these powerful treatment modalities.

In this week's episode, Blood editor Dr. Laurie Sehn interviews three of the latest Blood authors: Drs. Vijay Sankaran, Ruud Delwel, Françoise Kraeber-Bodere. Two studies on the MECOM gene have been paired in this episode, analyzing new groundwork for potential novel myeloid differentiation therapies via repression of MECOM restoring enhancer mediated CEBPA expression. We'll also hear about the results of CASSIOPET, imaging companion study of the CASSIOPEIA trial, and how achieving negativity in PET before starting maintenance therapy is significant even in patients who still show residual disease in the bone marrow.

In this week's episode, Blood editor Dr. James Griffin speaks with Drs. Emanuele Zucca and Sandra Pinho about their latest articles published in Blood. Dr. Zucca discusses his second analysis of the IELSG37 trial, where findings suggested that R-CHOP21 rituximab, cyclophosphamide,
doxorubicin, vincristine, and prednisone, administered every 21 days) may be a suboptimal frontline regimen for PMBCL. Dr. Pinho discusses the aging megakaryocytic niche and its influence on the age-associated decline in HSC and progenitor cell function. The authors demonstrate that remodeling of the megakaryocytic niche and associated platelet factor 4 (PF4) downregulation are central mechanisms driving HSC aging.

In this week's episode, Blood editor Dr. Laurie Sehn interviews authors Drs. Lorenzo Falchi and Robert Levy on their latest papers published in Blood Journal. Dr. Falchi discusses his work on an open-label, multicenter phase 1b/2 study evaluating fixed-duration epcoritamab with rituximab and lenalidomide in 108 patients with relapsed or refractory follicular lymphoma. Dr. Levy shares his work on demonstrating that in vivo expansion of Tregs in recipients prior to transplant is possible by activating TNFRSF25 (also known as death receptor 3) in combination with low-dose interleukin-2 in preclinical models. Both papers showed impressive and promising results for the treatment of lymphoma and GVHD.
