Outcomes of de novo AML patients whose CR sample was analyzed molecularly within a month after CR date according to whether their DNMT3A R882 mutations were cleared at CR or not.

Group 1 is defined as patients whose DNMT3A R882 mutation cleared below the VAF cut-off of 3% in their remission sample and who had no other AML mutation, and Group 2 is defined as patients with a DNMT3A R882 mutation with a VAF >3% with or without other AML mutations in their remission sample.
