Residential fine particulate matter linked to minimal residual disease in pediatric leukemia

AI Summary

A study of children with high-risk B-cell acute lymphoblastic leukemia found that higher residential PM₂.₅ exposure during induction therapy was associated with positive end-of-induction minimal residual disease. The finding links ambient air pollution exposure with a leukemia treatment outcome but does not establish causation.

For pediatric patients with high-risk B-cell acute lymphoblastic leukemia (B-ALL), residential fine particulate matter (PM₂.₅) concentrations during induction therapy are associated with positive end-of-induction (EOI) minimal residual disease (MRD), according to a study published in JNCI Cancer Spectrum.
