Patients who were MRD positive after induction and became MRD negative after consolidation chemotherapy C in the first course (n = 7) had a significantly worse DFS compared with patients who were MRD negative after induction chemotherapy A in the first course (n = 26) (69% vs. 29%, p = 0.004).Back to article page
