A Link Between Allergy and Hematological Malignancies? Focus on Possible Mechanisms and the Potential Role of Biological Therapies

Clinical and Translational Allergy, Volume 16, Issue 3, March 2026.
ABSTRACT Immune dysregulation has been widely recognized in the international literature as an underlying condition for hematological malignancies and allergic disorders. This commonality has led researchers to study the potential association, positive or negative, between blood cancers and allergy, but the results remain unclear.
