Key Takeaways
- In the United States, approximately 20,380 new cases of acute myeloid leukemia (AML) are expected to be diagnosed in 2023.
- The incidence rate of AML in the US is about 4.3 cases per 100,000 men and women per year based on 2017–2021 data.
- AML accounts for about 1.3% of all new cancer cases in the US, with 80% of cases occurring in adults.
- Exposure to benzene increases AML risk by 2-5 fold, primary in occupational settings like petrochemical industry.
- Prior chemotherapy with alkylating agents raises AML risk 10-100 fold, latency 5-10 years.
- Smoking doubles AML risk, attributable to benzene and other toxins in cigarettes.
- Bone pain present in 25-40% of AML patients at diagnosis due to marrow expansion.
- Fatigue and weakness reported in 90% of AML cases as initial symptom.
- Anemia (hemoglobin <10 g/dL) found in 85-95% at AML diagnosis.
- NPM1 mutations found in 30% of AML, often with normal karyotype.
- FLT3-ITD mutations present in 25-30% of AML, associated with poor prognosis.
- TP53 mutations occur in 10-15% of de novo AML, 40% in therapy-related.
- 5-year overall survival for favorable risk AML is 60-70% with intensive chemo.
- Intensive induction chemo (7+3: cytarabine + daunorubicin) achieves CR in 60-80% young adults.
- Allogeneic HCT 2-year survival 50-60% in first CR for intermediate risk.
Acute Myeloid Leukemia is a serious adult cancer most common after age sixty-eight.
