High prognostic value of pre-allogeneic stem cell transplantation minimal residual disease detection by WT1 gene expression in AML transplanted in cytologic complete remission

These data show that pre allo-SCT molecular MRD evaluation using WT1 expression is a powerful predictor of post allo-SCT outcomes in AML undergoing SCT in cCR. Patients with both cCR and MRD-WT1 negativity before SCT have a very good outcome with lower RR and improved OS. The pre allo-SCT MRD-WT1 stratification in AML is a valuable tool to identify patients at high risk of post-SCT relapse, and can influence conditioning regimen intensification and/or post-SCT preemptive strategies.
