ABSTRACT
Allogeneic hematopoietic stem cell transplantation (SCT) after a patient with acute myeloid leukemia (AML) achieves a remission from intensive chemotherapy (IC) is given with curative intent. Recently, venetoclax-based regimens have become the standard of care for patients with newly diagnosed AML who are unfit for IC. If these patients achieve remission, they may also be considered for potentially curative consolidation with SCT. There are limited data comparing outcomes after SCT with these different induction strategies. The purpose of the current study was to evaluate depth of remission before SCT and outcomes after SCT in adults with nonrelapsed/refractory AML receiving pre-SCT therapy with either venetoclax/azacitidine (ven/aza) or IC. This was a retrospective, single-institution analysis of 169 patients receiving SCT in first remission after IC or ven/aza. Patient demographics and AML risk features were collected, as well as pre-SCT measurable residual disease (MRD) assessed by flow cytometry and molecular methods. Relapse, transplantation-related mortality, incidence of acute and chronic graft-versus-host-disease (GVHD), and death from any cause were also recorded. Descriptive and survival statistics were applied to these data to compare IC and ven/aza groups. Cox proportional hazard models were used for univariate and multivariate analyses. We demonstrate that despite differences in baseline factors between these groups, outcomes were similar. Relapse-free and overall survival, as well as cumulative incidences of transplantation-related mortality, relapse, and acute and chronic GVHD were comparable between groups. Exploring survival in younger (<65 years) versus older (≥65 years) patients by treatment group did not alter these results. Finally, although pre-SCT MRD by flow cytometry was significantly predictive of post-SCT relapse and survival in the IC + SCT patients, it was not significantly predictive of relapse and survival in the ven/aza + SCT patients. Although these findings require prospective validation in a larger cohort of patients, they suggest that ven/aza followed by SCT is a reasonable management strategy for transplantation candidates at any age.
