This declines with age, with the poorer prognosis being associated with an age greater than 65 years, and the poorest prognosis seen in those aged 75–84.As of 2001, cure rates in clinical trials have ranged from 20 to 45%; although clinical trials often include only younger people and those able to tolerate aggressive therapies. The overall cure rate for all people with AML (including the elderly and those unable to tolerate aggressive therapy) is likely lower. Cure rates for APL can be as high as 98%. Subtypes
Secondary AML has a worse prognosis, as does treatment-related AML arising after chemotherapy for another previous malignancy. Both of these entities are associated with a high rate of unfavorable genetic mutations. Cytogenetics
Different genetic mutations are associated with a difference in outcomes. Certain cytogenetic abnormalities are associated with very good outcomes (for example, the (15;17) translocation in APL). About half of people with AML have "normal" cytogenetics; they fall into an intermediate risk group. A number of other cytogenetic abnormalities are known to associate with a poor prognosis and a high risk of relapse after treatment.A large number of molecular alterations are under study for their prognostic impact in AML. However, only FLT3-ITD, NPM1, CEBPA and c-KIT are currently included in validated international risk stratification schema. These are expected to increase rapidly in the near future. FLT3 internal tandem duplications (ITDs) have been shown to confer a poorer prognosis in AML with normal cytogenetics. Several FLT3 inhibitors have undergone clinical trials, with mixed results.
The FDA has approved certain epigenetic modifying drugs like ivosidenib and enasidenib, which are used in patients that can no longer receive intensive induction chemotherapy; specifically, they are involved in the therapy of IDH1 and IDH2 mutations. Further research must be done to prove the efficacy of epigenetic treatments, but the development of new epigenetic therapies along with immunotherapies holds potential in the future treatment of AML. In pregnancy
AML is rare in pregnancy, affecting about 1 in 75,000 to 100,000 pregnant women. It is diagnosed and treated similarly to AML in non pregnancy, with a recommendation that it is treated urgently. However, treatment has significant implications for the pregnancy. First trimester pregnancy is considered unlikely to be viable; pregnancy during weeks 24 – 36 requires consideration of the benefits of chemotherapy to the mother against the risks to the foetus; and there is a recommendation to consider delaying chemotherapy in very late pregnancy (> 36 weeks). Some elements of supportive care, such as which antibiotics to prevent or treat infections, also change in pregnancy. Medication
Olutasidenib (Rezlidhia) was approved for medical use in the United States in December 2022. Prognosis
Multiple factors influence prognosis in AML, including the presence of specific mutations, and a person with AMLs age. In the United States between 2011 and 2016, the median survival of a person with AML was 8.5 months, with the 5 year survival being 24%.
