These markers can be used to identify myeloid lineage. They allow the diagnosis of AML if there are no lineage-defining markers of B-lineage or T-lineage. Alternatively, if lineage-defining markers of B-lineage or T-lineage are present then consider a diagnosis of MPAL
Assignment of myeloid lineage: Lineage-associated markers | |
Myeloid lineage assignment using these markers requires that at least two myeloid lineage-associated markers are present | |
CD117 | An early marker of myeloid lineage, seen in up to 80% of AML and vauable in recognising more primitive differentaiion forms (note that aberrant expression is seen in up to 20% of ALL cases) |
CD33 | A good marker for AML, particularly for those cases with granulocytic maturation, CD33 is often less strongly expressed in AML with monocytic dfferentiation and strongly expressed in APL. |
CD13 | A good lineage marker for AML that is acquired a little later in differentation than CD117 or CD33; expression of CD13 is often higher than CD33 in AML with monocytic differentiation. |
