De novo AML patients were organized into poor-, intermediate-, and good-prognosis risk groups according to karyotype definition

	Cytogenetics prognosis group
Capacity for engraftment	Poor	Intermediate	Good
Yes, no. patients	5	18	0
No, no. patients	0	18	11

Four patients (nos. 7, 9, 10, 2) were excluded due to relapse, data were not collected for one patient (no. 22), and 2 karyotypes (nos. 4 and 5) failed at diagnosis. Engraftment correlates with poor prognosis; conversely, all favorable prognosis patients did not engraft.
