Etiology
Several factors have been implicated in the causation of AML, including antecedent hematologic disorders, familial syndromes, environmental exposures, and drug exposures. However, most patients who present with de novo AML have no identifiable risk factor.
Antecedent hematologic disorders
The most common risk factor for AML is the presence of an antecedent hematologic disorder, the most common of which is myelodysplastic syndrome (MDS). MDS is a bone marrow disease of unknown etiology that occurs most often in older patients and manifests as progressive cytopenias that occur over months to years. Patients with low-risk MDS (eg, MDS with ringed sideroblasts) generally do not develop AML, whereas patients with high-risk MDS (eg, MDS with excess blasts) frequently do.
Other antecedent hematologic disorders that predispose patients to AML include aplastic anemia and myeloproliferative disorders, especially myelofibrosis.
It’s one thing to treat AML, its another to stop it from happening in the first place

Will be Interesting if any of the control group developed AML
