Whether patients with acute myeloid leukemia (AML) harboring Nucleophosmin mutations (NPM1mut) with measurable residual disease (MRD) should undergo allogeneic stem cell transplantation (alloSCT) in complete remission (CR) remains subject of debate. This study aimed to assess whether the presence of bone marrow (BM) NPM1mut MRD, detected using a RT-qPCR assay with a sensitivity of 10-5, could influence the benefit derived from alloSCT. Data from four German transplantation centers were analyzed including 174 AML NPM1mut patients who underwent a first alloSCT between 2011-2022.

However, in the presence of their parental (helper) wt virus, DVGs can interfere with the replication, encapsidation, and spread of functional genomes, acting as a significant selective force in viral evolution. DVGs also affect the host's immune responses and are linked to chronic infections and milder symptoms.

These bursts can be triggered by external factors, such as environmental changes, antiviral therapies, or spill-overs from reservoirs into novel host species. However, it has also been suggested that bursts may result from the intrinsic evolutionary dynamics of viruses.
