We defined clinically relevant time points for NPM1(mut) MRD assessment that allow for the identification of patients with AML who are at high risk of relapse. Monitoring of NPM1(mut) transcript levels should be incorporated in future clinical trials to guide therapeutic decisions.

The addition of irinotecan to the standard AIO FU/FA regimen was associated with a highly significant improvement in PFS and response rate and was well tolerated. The results of this study confirm that irinotecan in combination with high-dose infusional FU/FA is a reference first-line treatment.
