Hi, Thanks for writing to HCM. I understand your concern for your husband, who unfortunately has acute myeloid leukemia. Acute myeloid leukemia (AML) is a type of blood cancer, which develops in the bone marrow from cells that would turn into white blood cells (other than lymphocytes). I understand that he has already undergone and on appropriate treatment of chemotherapy and blood transfusion. However, of all those with AML, around 20 out of 100 people (20%) will survive for 5 years or more after they are diagnosed. Younger people tend to do much better than older people. Factors that affect outcome for AML and that it is harder to treat if: 1. Age is older (over 60) 2. High white blood cell count when diagnosed 3. AML developed from a condition called myelodysplasia or because of the treatment for another cancer 4. Particular genetic changes (mutations) in the leukaemia cells 5. It takes more than 2 cycles of chemotherapy to get leukaemia under control. Hope the information provided would be clear. Wish him good health.
