Background:
Acute myeloid leukemia (AML) poses a significant global health burden. This study evaluates long-term trends in AML burden from 1990 to 2021, focusing on global and Chinese patterns using Global Burden of Disease (GBD) data.
Methods:
We extracted AML-related mortality, incidence, prevalence, and disability-adjusted life years (DALYs) from the GBD 1990-2021 dataset. Age-standardized rates (ASRs) were analyzed using Joinpoint regression to calculate annual percentage change (APC) and average APC (AAPC). Contributions of smoking, high body mass index (BMI), and occupational exposures were also evaluated.
Results:
Globally, AML deaths rose by 73.8%, with a 17.45% increase in ASMR. Conversely, China's ASMR declined by 14.76%. DALYs showed a global AAPC of -0.83%, with a sharper decline in China (-2.40%). Males and older adults (>65 years) bore a disproportionate burden. Smoking remained the top risk factor, while high BMI showed the fastest growth in attributable burden.
Conclusion:
While AML's absolute burden is increasing worldwide, age-adjusted metrics are stabilizing or declining in China, likely due to healthcare improvements. Targeted prevention, risk control, and geriatric-oriented AML strategies are urgently needed.

01:27Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
02:07Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
