Molecular monitoring versus standard clinical care in younger adults with acute myeloid leukaemia: results from the UK NCRI AML17 and AML19 randomised, controlled, phase 3 trials

Background

In patients with acute myeloid leukaemia (AML), finding measurable residual disease (MRD) usually means a poor outlook. This study looked at whether changing treatment based on MRD results could help patients live longer.

Methods

We studied patients aged 16-60 with newly diagnosed AML in the UK, Denmark, and New Zealand. We checked for specific markers in their blood that could help monitor the disease. Patients with these markers were divided into two groups: one group received MRD monitoring during treatment, while the other group received standard care without monitoring. Doctors in the monitoring group could adjust treatment based on MRD results. The main goal was to see how long patients lived.

Findings

In total, 2,801 patients were part of the trials. Of these, 637 were randomly chosen for either MRD monitoring or no monitoring. After about 4.9 years, the survival rates were similar: 70% for the monitoring group and 73% for the no-monitoring group. However, for patients with both NPM1 and FLT3 ITD mutations, the monitoring group had a survival rate of 69% compared to 58% for the no-monitoring group, showing a benefit from MRD monitoring.

Interpretation

Overall, MRD monitoring did not improve survival for all patients. However, it showed benefits for a specific group with certain mutations (NPM1 and FLT3 ITD).
