The study covered in this summary was published on researchsquare.com as a preprint and has not yet been peer reviewed.

Key Takeaway

  • Low serum albumin is significantly associated with 60-day mortality in primary acute myeloid leukemia (AML).

Why This Matters

  • Early mortality is a substantial problem in AML.

  • The results suggest that patients with AML whose serum albumin level is <35 g/L are most at risk for earlier mortality and require particular attention.

Study Design

  • Serum albumin was measured after admission in 394 patients with primary AML from January 2013 to May 2021.

  • Multivariable Cox regression was used to determine the relationships between albumin and 60-day mortality.

Key Results

  • Overall, 60-day mortality was 43.8% for patients with a serum albumin <34.5 g/L; it was 27.5% for patients with albumin levels 34.5 – 38.5 g/L; and it was 16.5% for patients with levels ≥38.6 g/L.

  • After adjusting for confounders, the researchers observed a 9% decrease in the 60-day mortality rate with each 1 g/L increase in albumin (hazard ratio, 0.91; P = .001).

Limitations

  • The study was retrospective and was limited to the Hakka population of southeastern China, a Han Chinese subgroup.

  • Unmeasured factors may have contributed to the increased risk of poor outcomes with low serum albumin.

Disclosures

  • There was no funding for the study; the investigators have disclosed no relevant financial relationships.
