Characteristics and Outcomes of Acute Leukemias in Adolescents and Young Adults with Down Syndrome: A Single-Center Experience

This is the authors' abstract. We don't add key points for this paper.

Background/Objectives: Acute leukemias in adolescents and young adults (AYAs) with Down Syndrome (DS) are understudied. Methods: This was a single-center, retrospective cohort study. Medical records for pediatric DS (n = 41) and AYA-DS (n = 7) treated with a pediatric chemotherapy regimen for acute leukemia were evaluated. Results: Two-year event-free survival (EFS) in AYA DS acute leukemia patients was lower than that in their pediatric DS counterparts (28.6% (Confidence Interval (CI) 4.1, 61.2) vs. 84.9% (CI 69.5, 92.9); p = 0.002). Conclusions: Additional research is needed to improve outcomes in AYA DS leukemia.
