What are the types of AML?

On this page:

World Health Organization (WHO) classification

The WHO classification system divides AML into several broad groups by the type of abnormal myeloid cell and if:

• There are genetic changes in the cells.
• The leukaemia developed from a blood disorder.
• The leukaemia developed after chemotherapy and radiotherapy.
• More than one type of blood cell has abnormal changes.

AML risk groups 

• Low risk: Your leukaemia is likely to be cured and there’s less chance of the cancer coming back (relapse). Low-risk patients won’t usually need a stem cell transplant, unless they relapse.
• Intermediate risk: It is hard to predict how you will respond to treatment. You may or may not need a stem cell transplant. 
• High risk: There’s a high risk of the leukaemia coming back (relapse) so you will have very intensive treatment. You are likely to have a stem cell transplant if you are suitable for one.
