Overview

This study demonstrates effective risk stratification in AML, implying advanced MRD protocols may enhance relapse prediction.

Key Points

  • To assess the efficacy of flow cytometry-based MRD monitoring for relapse prediction in intermediate-risk AML patients.
  • Evaluated post-induction MRD1 and MRD2 using an 8-color MPFC panel
  • Categorized MRD into Positive, Low Positive, and Negative
  • Analyzed clinical endpoints such as relapse-free survival and cumulative incidence of relapse using Kaplan-Meier and Cox regression
  • MRD positivity found in 21% of patients at MRD1 and 12.5% at MRD2
  • Significant association between low positive MRD and poorer relapse-free survival
  • MRD clearance by MRD2 linked to improved outcomes
