In this week's episode, we'll learn about stopping myeloma maintenance therapy in the modern era. New research suggests that many patients in remission can discontinue lenalidomide, remaining treatment-free, without jeopardizing disease response. After that: a novel congenital neutropenia syndrome. Mutations in the COPZ1 gene impact myeloid differentiation and development of neutropenia. Researchers describe the mechanisms and propose a treatment strategy for restoring granulopoiesis. Finally, ruxolitinib maintenance therapy after allogeneic transplant. In a phase 2 study, this treatment strategy was associated with low rates of chronic graft-versus-host disease. Investigators say the use of JAK inhibitors in this context warrants further study.Featured Articles: Sustained bone marrow and imaging MRD negativity for 3 years drives discontinuation of maintenance post-ASCT in myelomaA new severe congenital neutropenia syndrome associated with autosomal recessive COPZ1 mutationsLow rates of chronic graft-versus-host disease with ruxolitinib maintenance following allogeneic HCT
