AML with 11q23 (MLL) abnormalities

(2) AML with multilineage dysplasia

With prior myelodysplastic syndrome

Without prior myelodysplastic syndrome

(3) AML and myelodysplastic syndrome, therapy related

Alkylating agent-related

Topoisomerase type II-related

Other types

(4) AML not otherwise categorised

AML minimally differentiated

AML without maturation

AML with maturation

Acute myelomonocytic leukemia
