Frequency of aberrant cross-lineage expression on myeloblasts in MDS versus AML.

Immunophenotypic Myeloid Blast Aberrancy	Low/Int-1 Risk MDS Patients with Aberrancy (%) [26,27,31]	High Risk MDS Patients with Aberrancy (%) [27,31]	AML > 60 Years * Patients with Aberrancy at Diagnosis (%) [13]	AML < 65 Years * Patients with Aberrancy at Diagnosis (%) [32,33,34]
CD7 cross lineage expression	3.5–22%	3.5–16.7%	23%	25–32%
CD56 cross lineage expression	3.3–18%	?	19%	15–21%
CD5 cross lineage expression	<2%	<1%	ND	<1%
