In this How I Treat series episode Blood Associate Editor, Dr. Jason Gotlib speaks with Drs. Aaron Gerds, Andreas Reiter, and Claire Harrison. The conversation focuses on the work and contributions of these authors to How I Treat Myeloproliferative Neoplasms, and exciting advances in the treatment and management of MPNs.

In this week's episode we'll learn about the role of autologous transplant for relapsed myeloma. In an updated analysis of the GMMG ReLApsE trial, salvage autologous transplant offered no survival benefit compared to control chemotherapy. These findings may have clinical implications in an era of alternative, and highly effective, treatment options. After that: Response to DDAVP, or desmopressin, in bleeding disorders. This study is the first large scale meta-analysis to assess the response rate to DDAVP in bleeding disorders. Authors provide new insights into determinants of response, which vary according to the disease type. Finally, turning to diffuse large B cell lymphoma. Germinal center B cells depend on the activity of DOT1 and EZH2 to maintain their pro-proliferative identity. New research shows that combined treatment with DOT1L and EZH2 inhibitors has synergistic activity in vitro.

In this week's episode we’ll learn about the role of interleukin-1 signaling in the bone marrow microenvironment in the development of myelodysplastic syndromes, the immune checkpoint regulator VISTA as a potential target for preventing graft-vs-host disease, and epcoritamab plus gemcitabine and oxaliplatin in transplant-ineligible relapsed/refractory diffuse large B-cell lymphoma.
