The Bottom Line: AML patients with hyperleukocytosis receiving leukapheresis had a significantly lower risk for early death by Day 21 than patients treated without leukapheresis.

There were no procedure-related adverse events. By Day 21 of therapy, 13 of 53 patients had died, resulting in an overall early death rate of 25 percent. In a multivariate logistic regression model, patients in Cohort B had a significantly lower risk of early death than patients in Cohort A (16% vs. 32%, respectively). With a median follow-up of 24.2 months, the overall survival was similar in both cohorts (Cohort A, 7.5; Cohort B, 6.5 months). Thus, leukapheresis had no impact on patients’ long-term survivals.
